2.2.4 Benefits of Storage, as well as a database for storing a separate file for each sub-task will cause several benefits
2.2.4.1. Reduce the complexity of the data (Reduce Redundancy) because the data is collected in a single source to extract the diffusion model based on various machines, and reduce the storage can be time consuming data entry and wasted space. The store repeatedly to reduce the cost of backup
2.2.4.2. Reduce data conflicts (Reduce Inconsistence)
storage is a small file in a different assignment. When the update will erase the data. Add or edit information All must be done, otherwise it will cause data inconsistency problem occurs, for example, when the Drawing. Deactivate. Need to remove documents from the files
2.2.4.3. Is independent of applications and data storage by creating a file in various computer languages are structured files attached to this form of program thus created to improve the lack of independence because of the language. such as the nature of programming file storage application that language, but in the database procedure is done through a database management system or DBMS, which is like a common language to communicate so they can develop a computer language or program. that is compatible with standard database language SQL is also available and can handle all the data in the database is
2.2.4.4. In addition, such action would have to write a program to deal every time takes up time and cost quite a lot. The characteristics of the database can be done right away, just to pass the DBMS without consequences or risks to the data storage
2.2.4.5. Or to input the value set, if the user enters invalid data conditional DBMS systems will reject it without storing the data and alert the user to know until you enter the correct terms. given
2.2.4.6 Data generated in the database to a standard can be used widely as it is used within the agency, but also bring such information to use in the Internet with it and that was the benefit of both present. and to support the future use
2.2.4.7. There is the security of the data in the database to get the security service by the DBMS will be given the right to access and store the data of each user to vary, thereby preventing data changes or. Any action that may cause damage to data from intruders or no rights.
