Differwnce between datasheet and design view?
A datasheet view displays data in a tabular format, showing records and fields in rows and columns, making it easy to view and edit data entries. In contrast, a design view is used for creating and modifying the structure of a database object, such as tables, queries, or forms, allowing users to define field types, properties, and relationships. Essentially, the datasheet view is focused on data management, while the design view focuses on database structure and design.
What are the 2 views of table in access?
In Microsoft Access, tables can be viewed in two primary ways: Datasheet View and Design View. Datasheet View displays the data in a spreadsheet-like format, allowing users to easily view, enter, and edit records. Design View, on the other hand, provides a structure-oriented format where users can define or modify the table's fields, data types, and other properties. These views cater to different tasks, making data management more efficient.
