Introduction To Microsoft Access 1. Microsoft Access allows users to create and manage databases and includes tools to design tables, queries, forms and reports. 2. Key components of an Access database include tables which contain fields to store records of data, and templates which determine the structure and format of a database. 3. Custom formats and input masks can be used to define the type and format of data for fields, such as dates, phone numbers or currency values.
