Databases, or DBs, are collections of information or data organized so that computer applications known as database management systems (DBMS) can quickly and efficiently access specific data from the database. The data in traditional databases are organized by fields, records, and files, with a field representing a single item of information, a record being one complete set of fields and a file serving as an entire collection of records.

From the earliest navigational and relational databases to today's object-oriented and NoSQL databases, our databases dictionary offers a glossary of key terms you need to know.
