The general meaning that the term database constitutes is that it is a collection of data. This is the definition that is commonly used or described to the term for a layman's understanding. However, technically, or in a more detailed explanation, the term database can be further explained as follows: it is a collection of data that is systematically organized in a structure of related data for better storage and retrieval of information.

             In almost all kinds of system whose purpose is to provide information, a database plays an important role because it is the central component of a system where information are stored and retrieved. As indicated by Wikipedia, it is the component that answers queries of the users.

             An ideal database is one whose structure is designed to allow quick access of information. This is done through the use of different database models representing how a database is structured. In a database, it is important that data are optimized while the relationship between data is maximized to allow multiple ways of using all available information.

             In general, a database is the life of information technology. Without a database, systems whose purpose is to provide information will not achieve the functionalities that they are able to perform these days; they can not perform complex processes in just a split of seconds; and systems will not be as indispensable as they are today if not for the purpose that a database provides. Hence, information technology may have not reached the power and capabilities that it proves in the present times if not for the critical role that a database plays.

             Why is a Database Important Today?.

             Almost everything that we used to do manually can now be done by automation in a quick span of time because access to information is no longer today's problem. For instance, some years ago, finding information entails an individual to turn from pages to pages and books to books in a library where the cost certainly includes time and energy of the person.
