Mobile database application is an effective way to optimize business processes and ensure that end users always have access to critical business information they need to perform their jobs. Despite the fact that large companies are usually the largest investment in mobility, small businesses can also benefit from the mobilization of their data.
“Mobile” is not the same as the “Internet”
Some people equate “mobile” to “online”, but not the same. Internet applications require a network connection, consistent and reliable to external servers. The browser-based applications is a classic example of a Web application.
A truly mobile application, however, is an application that continues to operate even when the network connection is lost, as opposed to an online questionnaire. To “separate” from the network does not stop the application in their tracks. This is an important feature for many users. Many mobile workers move in and out of the network on a regular basis while doing their jobs, but they need the information to be “always ready”. On-line solution that does not work very well for this type of worker.
Local data = Speed and simplicity
Mobile applications work best when they include some sort of local storage. Supporting mission-critical data local to the device, users are isolated from each network connection problems. Faster data operations (no network lag) and can occur at any time. This leads to a much better experience and less frustrating for users.
Of course, the use of local storage to make the development and implementation of mobile applications is more complex. Even if the application works independently, without the network, eventually a kind of communication must occur between the local data store and one or more external servers. Depending on the application design, monitoring changes and resolve potential conflicts can be very difficult to manage. Mobile database applications often takes more time and more skill development than the online equivalent only because of this.
Network to reduce costs
Besides offering the best user experience, mobile applications and databases can provide significant cost savings in the network. The cost elements in the network can be very high when using Web-based applications, especially web applications. Back and forth constantly between the device and application hosting server rack at the end of the network fast enough. The mobile application is well designed, on the other hand, requires only minimal use of network sharing and data changes are not the entire data set.
While the investment costs for mobile application development database, which is usually higher than an interactive application, the savings in network costs can be significant and make the application more efficient than its counterpart on the Internet. It’s definitely something to consider when developing or purchasing mobile applications.Tags: data mobile, device users, external servers, line solution, mobile database
Protecting your personal information is becoming increasingly necessary as the number of sites that require personal information increases. There are more and more sites that you can buy goods and more sites, spyware, adware, malware and viruses. All this may lead to your information sent over the Internet with other companies, or you may end up losing your data due to accidents.
Firewall security is to provide protection from a variety of things. First, the firewall will limit the program have access to the Internet from your computer. This is to prevent personal information transmitted to the creator of spyware, adware and viruses embedded in your computer, but it also prevents the programs to update automatically. As a result, the need to manually rather than automatic updates.
Firewall to ensure security and provides protection when connecting to the network. This will help to prevent Web sites to access your computer while browsing the Internet. There are different types of sites you can visit the site every day trying to get access to a computer. Firewall security can provide an extra level of security.
There are several things to consider when using a firewall. You should carefully review the program settings to make sure that you end up blocking access to the Internet completely. And “one of the main complaint firewall. They can also block any site that uses a connection, like streaming video sites, download sites and file storage.
The need for this program, however, can not be denied, there are more and more sites that can create problems with the firewall, and there are several different levels of government, the firewall can be configured depending on the type you get. You can go with a software firewall is the most basic security, which can be found in versions of Windows. It does not offer much flexibility when it comes to the development of licensing and monitoring.
There are many different applications, a firewall for security. There is also an application firewall that comes with a set of Internet security and standalone applications. They also have many functions, thus providing greater flexibility. Firewalls can also help ensure privacy and allow you to block certain types of sites. Most firewalls have the ability to block certain sites, and can even help with parental controls to protect his family.
There are several types of firewall. Some of the other major applications only more complicated, but all have one thing in common they are designed to limit access to the Internet and computers to limit access to the Internet on your computer.Tags: file storage, information increases, program settings, protecting your personal information, video sites
Why Web Application Security Web Application Security is the most overlooked aspects of the company’s current software. Theft is on the rise by as much as 75% of cyber attacks are done by using the Internet and use Web-based applications.
Most companies have provided their data at the network level, but missed a crucial step in testing their web applications are vulnerable to attack.
The web application used to create certain security issues. 1. For delivery of services (design plans) for clients, Web applications should be available online 24x7x365 and 2. This means that they are always accessible and can not distinguish between legitimate users and hackers 3. For proper operation of the Web application should have direct access to the database server that contains sensitive information. 4. Most Web applications on your order and rarely pass through stringent quality control check the application ready to use 5. Through ignorance of the nature of hacking, organizations view the Web application layer as part of the network level, when it comes to security issues.
Infrastructure Security Organization convenient to think of infrastructure as an organization with different layers. In the same way you would be protected from rust by using various chemicals and antioxidants in the layers of paint, the system administrator puts into place a number of specific security solutions for each deal with specific areas of concern.
Level of security is an integral worldview is seen as a security hardening steps to minimize risk and maximize the intrusion protection around the key asset of any organization, data.
Layers of standard safety features include:
- Layer that contains the user’s software, including personal firewall, anti-rootkit, clean registry, backup, anti-virus, anti-phishing and anti-spy/adware.
- Transport layer, including SSL encryption, HTTPS, and the same protocol
- The level of access with access control, authentication, crypography, firewall, VPN, firewall, web application
- Network level with firewalls, network scanners, VPN and intrusion detection.
While network security scanner, Safety Analysis of assets on the network for possible vulnerabilities, Web vulnerability scanner (WVS), scan and analyze web-based applications (such as shopping carts, forms, login pages, dynamic content) for each gap due to improper coding that can manipulated by hackers.
For example, it is possible to trick the shape Login to believe that you have administrator rights by introducing a specially crafted SQL (a language understood by the database) command. This is only possible if the input (eg, user name and / or password field) due to sufficient processing (ie, made invulnerable) and sent directly to the SQL-query to the database. This is SQL Injection?
Network security defense provides no protection against such attacks, Web applications, such attacks are launched on port 80 (default for Web sites), which must remain open for business interruption.
Black box testing black box testing methodology to test only design .. In black box testing of web applications, web application itself is considered as a whole, without analyzing the internal logic and structure. Typically, scanners, web applications, whether web-based application can generally be manipulated to gain access to the database. Modern technology allows a greater degree of automation, in fact, reduce the manual input required for testing web applications.
It is important to say, reduction, and not to minimize or do away with. As well as security consultants will tell you, the automation will never replace the intelligence and creativity of human intervention.
In general, the first automatic scanner crawl the entire site, in-depth analysis of each file, they will find and display the entire website structure. After the discovery phase, the scanner automatically checks for vulnerabilities by launching a series of hacker attacks, basically mimics hackers. Scanner will review each page to the place where data can be entered, and then will try all the different combinations of inputs. Scanner will check vulnerabilities on web servers (to open), all Web applications and content of the web site itself. More reliable launch attacks using a variety of products such as smart heuristics level.
Heuristic Scanning the Web is important to understand that a web vulnerability scan should not be limited to specific scanning applications (such as ready mix truck) and / or vulnerability module (for example, from SQL injection, in phpBB Login Form) to the pre-defined library of known issues. If you wish to do so, your application will remain untested for their vulnerability. This is the main weakness of the products is based on matching vulnerability signatures.
Consider the anti-virus software as an example. Standard anti-virus software to scan thousands of known viruses, including viruses and is known for a long time (even those made for Windows 95 systems older). In this day and age it is rarely encounter this OS, but in the minds of consumers, most importantly, “how much virus software detect it?”. In fact, with the latest AV will provide protection for all but the virus works in the wild And this is the virus that causes the greatest damage .. Standard AV products without the right technology will not detect the virus in the wild if they can meet only “known” viruses. Good antivirus technology enables heuristic scanning of files or intellectual trying to find a way to model the behavior of applications that can cause the virus.
Web vulnerability scanning works very similar. It would be useful to detect known vulnerabilities known to the application only. Most of the heuristics involved in the detection of vulnerabilities hackers are very creative and begin their assault on custom web applications to create maximum effect.
Of course, this approach does not give false positives, but there is confusion and chaos. False positives occur due to an automatic scan flag problems that may seem vulnerable. Automation invaluable help and scanning accuracy depends on (a) how well your site is crawled to establish its structure and various components and connections, and (b) the ability to use the scanner wise variety of methods and techniques hackers against Web applications.
Automatic verification will lead to false positives. Of course, this level of technological complexity does not lead to zero false positives. It’s impossible. Automatic scanning will always result in false positives, depending on the products you use.
We always recommend automated scans must be coupled with a manual scan – this may be one point that all security experts emphasize. Unfortunately, companies do not realize the importance of manual input. If you want your web application will secure you need to spend considerable time examining the automatic side of things. This does not mean that automation is inaccurate – instead, it is very accurate and reduces a lot of work. Automatic scanning will help you to flag potential problems, including false positives and manual further investigation quickly.
Source Code Analysis A set of products related to web vulnerability scanning source code analysis, but they work differently for web crawlers vulnerability. Source code analysis of white-box testing tool that helps developers in their work, automatically analyzing the internal structure and logic of the source code itself for errors and security loopholes. The degree of complexity of these products is based on the specific application logic and a different coding languages. This means that there are some stable product on the market, while technology is moving very fast.Tags: integral worldview, intrusion protection, quality control check, stringent quality control, web application security
As the Internet has become a major player in the global economic front, so did the number of investors interested in its development. Thus, you may be wondering how the Internet continues to play an important role in communications, media and news? The key words are: Web Application Projects.
Web applications are business strategies and policies on the Internet with user communication, business and data. This tool is where the future. In this article I will take you through the important phases of the life cycle of a Web application project, explain what options you have and help you develop a plan for successful Web application is the business itself. But first, let’s overview of Web applications.
Who needs a web application and why?
There are many organizations that require applications for the Web-one example would be business-to-business interaction. Many companies in the world today demand to do business with each other on security and private networks. This process is becoming increasingly popular with many foreign companies who outsource projects to each other. From the simple process of transferring funds to a bank account for a large-scale deployment of Web services network, updating the prices on a global scale, the adoption of Web applications infrastructure is vital for many businesses.
Web application model
Web application model, like many software development models, built on 3 levels: User Services, Business Services and Data Services. This model breaks an application into the network of consumers and service providers.
Level of service user creates a visual gateway for consumers to interact with the application. This can range from basic HTML and DHTML to complex COM components and Java applets.
The user services then grab business logic and procedures for business services. This level can range from Web scripting in ASP / PHP / JSP server programming like TCL, CORBA and PERL, that allows users to perform complex actions through a web interface.
Last layer is the Data Service layer. These services store, retrieve and update information at high levels. Databases, file systems, media and writing are examples of data storage and retrieval devices. For Web applications, however, most practical databases. Database allows developers to store, retrieve, add and update information in a systematic and organized categorically.
Choosing the Right Projects
Assessment of your resources, technical skills and abilities of publications should be your first goal. By considering the three levels, to develop a list of all available resources that can be categorically assigned to each level.
Next consider the price. Do you have a budget that can be used to complete this project? What is the cost to design, develop and deliver a complete project with considerable success? These are questions that must be answered before you sign an agreement or contract.
Let’s look at an example. A company called ABC needs to develop a web application that will display sales information created by agents of different sales. Data is updated every day through a fully automated process from all three levels of service. The client tells you that the entire project should be done in ASP / SQL-server and you have to host applications as well.
After assessing all your resources, you and your team come to the conclusion that the company can not perform backups every day. After further discussion, you realize that this is a very important part of the setup for your clients, and you do not have to risk the possibility of the project. It is very likely that you will be better prepared next time a similar project lands on your desk so you refuse to work and to recommend others who could use this right now.
Stages of Web Application Project
Web application development process has four phases:
- In presenting the nature and direction of the project
- Develop a plan
- Testing, support and stability
- Let’s look at each in more detail.
1. In presenting the nature and direction of the project
At this stage, management and developers are working on a project to come together to set goals, decisions must be reached. This includes recognition of the limitations placed on project planning and management of application versions. At the end of this stage should be clear documentation that the application will be achieved.
2. Develop a plan
At this stage, you and your team must determine “what” of the application.
What scripting language is most appropriate, what features should be included and how long will it take? Here are some questions to be answered at the planning stage. The main tangents at this point, the project plans and functional specifications. The project plan defines the activities and tasks, while the functional specification outlines in detail how the application will work and flow.
Upon approval of the project plan and functional specification are ready, made for the basic development work begins. Developer programmer / s or website / from the initial coding, testing and publishing data. This phase sets the variable data, organization, and coding procedures that will be used for the rest of the project. Landmark document prepared by a team of developers, who then provide the leadership for consideration.
4. Testing, support and stability
The stability of the implementation phase of this project is mainly focused on testing and fixing bugs, inconsistencies, and network problems that may cause the application to fail. It is here that the policies and procedures established for a successful support system.
Knowing your options and use them wisely
Well, now you have an understanding of architecture and procedures for developing web applications, let’s see what technical options should be considered for the development process itself.
Windows Web Server
Microsoft has built a loyal customer base to one important factor – easy-to-use their software. Windows NT/2000/XP Web server is very fast and easy to operate. The fact that the operating system Windows Shell means that administrators and authors can easily create a Web server to communicate with other application software and hardware for transmitting and receiving data over the Internet. Server popular scripting language that is used with the Windows server, the ASP / ASP. Net, Java Server Pages and PHP.
UNIX / Linux, Web-server
UNIX has long been known for their reliability. This is a web server and a powerful and reliable operating system. Unix is a server of choice for many large sites that require content management system, or receive a large volume of traffic. A popular server side scripting language for UNIX is a Java Server Pages, PERL, PHP, and CORBA
Each scripting language has its pluses and minuses. I am not writing a book here, I will use the ASP model, as a work of art my tongue. When dealing with a Windows server, there are some important parameters that developers have to throw in the equation, including security, speed scalability, and application development. So below I will help you formulate a successful plan for all types of web projects.
In order to dramatically reduce the risk of project failure, I always approached my projects to develop applications in the following order.
1. Specify the business logic and entities
To start collecting information about everything you do. If you want to work with the database, start by listing the number of people that will be used in business logic. For example, if your program provides data on sales, ticket sales will face.
Once you have identified all of your face, to establish clear guidelines for their relationship. This can be done through presentations, flowcharts, or even reports.
2. Creating the functional specification and project plan
This section is, in my opinion, is the most important part of the project. Functional specification (or functional specification) is a map, or plan for how you want a particular web application to look and work. Specifications detail what the finished product will be done, user interaction, and appearance.
The advantage of writing a functional specification is that it simplifies the development process. He received the difference and eliminate the programming process, because the level of detail, which is part of a plan to minimize the misunderstandings that are usually associated with project failure. See examples of well-written functional specifications for RayComm.com.
After completion of functional specifications, project plans must be developed. Task of the project plan and timing of events that occur during the project. Project or program manager, as a rule, a person who creates the project plan, and focuses on the record the issue in detail, able to accommodate resource planning and information. You can download the sample Excel file for the draft plan Method123.com.
3. Bring the application model in the game
As already mentioned, the application model consists of three levels – the level of user, business and data services, each of which serves an important purpose.
Practically speaking, it is always better to start with a level of data because you have identified the person and understand their relationship. Level data can be SQL-server databases, text files, or even Oracle’s robust and reliable. Creation of tables, relationships, work, and procedures, depending on what platform you choose. If the data warehouse (ie, data that already exists and does not depend on the actual interaction time), then make sure that new and additional data can be added safely and measurable.
Quick tip: Using the representation in SQL Server / Oracle can dramatically improve performance and application performance. They increase the speed, because they are “stored query” which has no physical existence.
Level of commercial service, in my opinion, is the heart of the application. This includes the implementation of business logic in the script or programming language.
At this stage, make sure you have created their own environment for testing and debugging. Always make sure that at least two copies of your application, in the end, which can work well for you, can not do well on other platforms or machines. ASP, XML, PHP, JSP, CGI, and some examples of server-side scripting language used in business services. Whatever language you choose, make sure it can handle all the business logic is represented in the functional specification.
Final user level, which is absolutely necessary for the interactive and strategic element in the application. This provides the user with a visual gateway to business services posting images, icons, graphic elements and layout in strategic areas of interest are often based on management studies. If you develop your own user-level, be sure to have learned from competitors. The last thing you need is your application to look exactly like everyone else.
4. Develop a support scheme
Able to support and stabilize your application is very important. Definition of procedure calls for cases of failure, failure, and even downtime. Giving your customers the opportunity to contact you in an emergency related to the program.
A good example of schema support ticket tracking system. This system allows users to make their case regarding the request for support and support, making the case tracking capabilities. This means that the request is identified by a unique code or number. Although the ticket tracking system, commonly used hosting company or a large scale in the ASP (application service provider), they still serve a useful purpose in helping to keep the application stable.Tags: business interaction, scale deployment, services business services, web application development, web application project
To meet the automation of sales and services process, the database is usually needed for the database that hosts what to consider when choosing a web host for you Internet business.
The database is nothing more than a set of interrelated information or data is stored electronically on computer for easy access. There are different types of database programs which can be used to integrate different applications and create a central database, which increase the efficiency and the efficiency of business operations and business management.
Some database programs, turnkey applications can only be install and use, but for automation, database The parameters usually have to be adjusted. Because the Internet automatically companies tend to combine with their database solutions Site to automate the online business functions, databases, the necessary facilities.
When choosing a database hosting company is more important that you choose one that has the technology and software storage that meets your needs and integration requirements related to business process automation.
In order to effectively evaluate and select the database that hosts Alternatively, you can select the database solution integration with existing systems of your business, or to change the entire system to ensure compatibility and the ability to integrate and automate business functions efficiently.
Some programming languages ??are most widely used database provides automation capabilities, including Oracle and SQL, though There are many more. The database host must choose able to maintain the database and Automation The function of the programming language used by your enterprise applications on your computer.
Because automated databases and planning special enough and highly technical in nature, it is wise to seek advice database programming services professional or Special automation.
Statement on the computer, the solution to your database and you database that houses all have to work together effectively automate business processes for maximum efficiency.
Every business has its own unique business processes, however, several key business functions and enterprise systems Benefits include automated point of sale systems, operating Systems, marketing, accounting and information systems management systems.
Using a database that hosts the database, the system We all can be integrated so that data shared between them. Automation through the integration of companies to significantly improve functions and processes, such as data entry, archiving and research That will enhance your online business for the higher level of service and productivity with faster and easy access to relevant information when you need it.
Customer Relationship Management (CRM) is an example of The functions that can help your business by automation and database hosting. An effective system of CRM, which allows manage the business to learn more about their customers and The prospect that they can build strong, lasting relationships with them.
CRM brings a wealth of information about customers, prospects and market trends that can be used to improve marketing and building sustainable relationships with customers through a monitoring service. CRM system that is activated process automation and database web hosting does not give you provide products and services that you expect customers It is necessary to facilitate cross-selling and building areas.
Management Information System is another example of a function work using an automatic exchange of information through hosting the database, which gives management more accessible to more variety of information that can be used to build business activities.
Without a doubt, the benefits of business automation. Automation makes standard business functions are simpler, more practical and more effective in terms of time and cost. Using databases and effective database hosting option that allows automation.
Select the database and database application hosting suppliers is an important first step towards automation and release the full potential of your online business.Tags: automation capabilities, business process automation, database programming services, solution integration, turnkey applications
