?What is the purpose of a primary key in Microsoft Access databases

A primary key in Microsoft Access databases serves as a unique identifier for each record in a table. It ensures that each record can be uniquely identified and referenced within the database. By defining a primary key, Access enforces data integrity rules, preventing duplicate records and maintaining the integrity of the database structure. Additionally, primary keys facilitate efficient data retrieval and manipulation operations, such as searching, sorting, and joining tables in queries.

? How do you create a query in Microsoft Access to retrieve specific data from a table

To create a query in Microsoft Access, first, open the database and navigate to the "Create" tab on the ribbon. Then, click on the "Query Design" button to open the query design view. In the query design view, select the table from which you want to retrieve data and add it to the query design grid. Next, specify the fields you want to include in the query by dragging them from the table into the query design grid. To define criteria for filtering the data, use the criteria row in the query design grid. You can also specify sorting and grouping options for the query results. Finally, run the query to retrieve the desired data from the table based on the defined criteria.
