Information technology requires automated database system to manage information for storage and retrieval. The ideal recommended system should have large storage capacity, secured connection, and faster data transfer speed which purely depends on hardware and software competency. There are range of database management programs that are commercially available such as MSSQL, ORACLE and many others and there are even open source database systems that can be downloaded from the net but they are expected to have some bugs as these are mostly under development stage. The basic set-up of a database requires interface in processing the information. This interface is a program that is usually platform dependent which depends on the compatibility with the system. The processes involve queries (SQL) that are mostly in common format in most of the systems.
Secured information in the database are processed with various encryption methods so that they are unreadable for unwanted third party access and must have multiple level of protection system. The trade-off for security will be processing speed as there would be delays during the decryption or encryption of information.
