Microsoft Access is a program used to create and manage databases. It allows users to construct tables to organize data by topic, with each table containing multiple fields of different data types. Users can enter and manipulate data by adding, updating, or deleting records directly in a datasheet view or a form created using the wizard. Reports can also be generated using the wizard to display data in a formatted layout for printing. The main components of an Access database are the database file which stores all the data, tables which organize information into topics, and fields which are the categories within each table.
