This means that even after 20 years old database with billions of records as long as it has been properly designed and maintained, it will still search rapidly and return results fast whereas doing it manually, each growing record slows down to end point of search; and finally, 4) with electronic database you can always build it up, redesign or customize database, etc. to meet your data requirements” (Husin, 2008).
Presently, IT CEOs, CIOs and administrators deal with increasing explosion of data growth. Thanks to modern science that is keeping up with the rapid pace of development in the industry of Information and Communication Technology (ICT). New enhanced features on data storage technology have been added to include backup, archiving and disaster recovery built-in mechanisms to protect stored data and these are milestone achievements. Another featured enhancement is, increasing data storage capacity to accommodate greater volume of data of any format. Second, if before only digitized data can be stored in a computer, today, all data formats from text messages, images, sound, voice, pictures, scanned data, music and movies, among others are now accepted for storage, retrieval, manipulation and sharing. More and more enhanced features will be introduced since the number of different types of computer users have increased immensely in keeping pace with service requirements and ICT developments.
The different types of new computer users include data miners, explorers, departmental users, multidimensional users, power users, and executive users. This situation requires alternate storage mechanisms to respond to the needs of the industries. In response to the demands of these varied types of computer users, new hybrid storage systems are now introduced: direct attached storage (DAS), storage area network (SAN) and network attached storage (NAS) (“Enterprise Data Storage”, n. d.). Enterprise business storage is also one of the
