Here are some reasons why you should use a database, relational databases and, in particular, our data:
Reducing Inconsistency
The database is created to ensure that all information is stored only once. If the file has changed, then replaced on all reports. With other methods, such as files or written records that can be modified, if necessary, the data in one place and do not forget to upgrade to the next.
Fewer errors
A lot of information that can be inserted into the drop-down list. For example, if a student is to add a category to find a program that actually use the drop-down list to prevent knocking in a category that does not exist in reality. Without a database, which can mean the name wrong course or a class type, which was recently discontinued.
Totals
The data in the database quickly spread. If I recall the days of my office when we use paper, I always study, which has a particular file, and you should find a file necessary data. If you have a database that can easily find the latest entry at this time is accumulated in a variety of people and is registered in the standard way.
The calculation is done only once
Using the database, the formula or calculation is made once every time you work with the latest data. The problem with spreadsheets Excel, as in the fact that we have to change the sheets, and sometimes a new formula for the calculation. For example, when we add the data that we have to insert a row, and possibly create a new data aggregation. It should also ensure that our people are still focusing on the appropriate cells.
Security
A certain amount of data in a corporate or sensitive personnel. Database applications have security measures with the user ID and password, and you’ll have a set of tables locked so that only authorized persons. It is much better than the files that have been deployed in the office or organization that is very difficult to maintain.
Ease of use
Databases can be simple to use. We can build a menu which is a completely different options for different end users. As a result, the receiver can only find the button, which should also contact information for employees, but the administrator can see the buttons for research and personal archives.
