Defining Fields

After creating a table, it’s essential to switch to Design View to define its fields accurately:

• Switch to Design View: In the Datasheet view, click on the “View” button on the Ribbon and select “Design View.”
• Define Field Names and Data Types: In Design View, you’ll see columns for “Field Name,” “Data Type,” and other properties. Define each field by entering a name and selecting an appropriate data type. Common data types include Text, Number, Date/Time, and Yes/No (Boolean).
• Specify Field Properties: Along with data types, you can specify additional properties for each field to enforce data integrity and validation. These properties include field size, format, default value, and validation rules.

Primary Key

Setting a primary key is crucial for ensuring data uniqueness and establishing relationships between tables. Here’s how to set a primary key in MS Access:

• Identify a Unique Identifier: Choose a field or combination of fields that uniquely identify each record in the table. This field(s) will serve as the primary key.
• Set Primary Key: In Design View, select the field(s) you’ve chosen as the primary key. Click on the “Primary Key” button on the Ribbon to designate the selected field(s) as the primary key.
• Enforce Data Integrity: By setting a primary key, MS Access ensures that each record in the table has a unique identifier. This prevents duplicate records and facilitates efficient data retrieval and manipulation.

Here’s a simple example of a table structure:

Field Name	Data Type	Description
ID	AutoNumber	Unique identifier
FirstName	Text	User’s first name
LastName	Text	User’s last name
Email	Text	User’s email address

Formulating Queries in MS Access

Queries are essential for extracting and manipulating data. This section of the Access database tutorial will demonstrate how to create basic and advanced queries:

Creating Simple Queries

Simple queries are designed to retrieve specific data from tables based on user-defined criteria.
