- A database is an electronic filing system for organizing and storing data that relates to a broad subject area, like sales and inventory.
- A database that lets you organize data so you can easily define and exploit relationships among data is called a relational database.
- At the top level, a database is made up of tables. A table is a collection of records about a specific subject, like customers.
- A record is a collection of pieces of information, called fields, about one thing, like a single customer.
- A field is a specific item of information, like a customer name.
- An index uses data from a field or fields as the basis for searching, sorting, or otherwise processing records.
