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
