Access is a database management system (DBMS) software used to create and manage databases. It allows users to create tables to store information on topics like students, fees, teachers, and exam details. Tables contain fields for specific pieces of information and each field has a data type like short text, number, or date/time. Users can view tables in datasheet view to enter data or design view to configure fields and set the primary key, which uniquely identifies each record. Queries in Access allow users to view, change, and analyze data from tables in different ways and can also be used as a source for forms and reports.
