A Database (DB)is a collection of information organized in a way that a computerprogram can select the desired pieces of data quickly. In other words, the information is organized in such a manner that it can be easily accessed, managed and updated.
You can think of a traditional database as an electronic filing system, organized by different fields, records and files. A field is a single piece of information; a record is one complete set of fields; and a file is a collection of records.
Hypertext is another alternative concept in database design. In Hypertext database, any object, be it text or a picture, can be linked to any other object. Hypertext databases are particularly useful for organizing large amounts of disparate information, but they are not designed for numerical analysis.
Data is organized into rows, columns and tables, and it is distributed to make it easier to find relevant information. This data can be updated, expanded and deleted as the new information is added. Databases process are worked to create and update themselves, querying the data they contain and running applications against it.
