I will analyse and design databases

A database, often abbreviated as DB, is a collection of information organized in such a way that a computer program can quickly selectdesired pieces of data.

You can think of a traditional database as an electronic filing system, organized by 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. For example, a telephone book is analogous to a file. It contains a list of records, each of which consists of three fields: name, address, and telephone number.
