Microsoft Access, a relational database management system, uses a variety of objects to help users design and manage databases. Understanding these objects is crucial for effectively working with Access. Here are some key MS Access objects:
Tables:
- Purpose: Tables store data in a structured format.
- Understanding: Tables consist of rows and columns, where each row represents a record, and each column represents a field or attribute. Primary keys uniquely identify records.
Queries:
Purpose: Queries extract, filter, and analyze data from tables.
- Understanding: Queries are SQL statements or visual representations that retrieve specific data from one or more tables based on specified criteria.
Forms:
- Purpose: Forms provide a user-friendly interface to interact with data.
- Understanding: Forms are used to enter, edit, and view data. They can be designed to control data input, display calculated fields, and trigger actions.
Reports:
- Purpose: Reports present data in a formatted and printable layout.
- Understanding: Reports are used to generate formatted documents for printing or sharing. They can include calculated fields, groupings, and summaries.
Modules:
