A computer database is a huge compilation of electronic files stored at a single location that is designed and modeled to support processes that require storage and retrieval of relevant information without a lot of work to the user. Computer databases are generally run and managed by specially designed applications known as database management systems software. These management systems allow users to add, edit, manipulate and store data as needed.
The term database is commonly applied to any collection of files on a computer system, but in the strict sense, a database has the unique feature of cross-referencing information, which allows users to rapidly find files by typing in keywords relevant to the file they are querying.
According to Computer Hope, a database is also called a databank, and some examples include mailing lists, library records, school registry systems, airline booking systems and company employee records.
Bigger organizations use a more sophisticated centralized database system to support internal operations, track inventories, track sales records and assemble customer lists. These specialized systems can store a combination of different types of files, such as digital pictures, videos, word files and spreadsheets, and allow employees to access multiple types of files from different locations within the organization's premises.
