What is database?

A database is a collection of data that’s organized for easy access and manipulation. The most popular database model is the relational database in which data is stored in simple tables. A table includes records and fields. For example, a table of students might include first name, last name, major, year, student ID number and grade point average fields. The data for each student is a record, and the individual pieces of information in each record are the fields. You can search,sort and otherwise manipulate the data based on its relationship to multiple tables or databases.For example ,a university might use data from the student database in combination with data from databases of courses, on-campus housing, meal plans, etc
