Access 6 an entity represents a concept or object you want to store data about Think of it as a table in your database Entities consist of attributes also known as fields that describe the characteristics of the entity For example a Customer entity might have attributes like CustomerID Name Address and Phone Number Key Components of an Access 6 Entity Fields Attributes Each field defines a specific characteristic of the entity For example within a Product entity ProductName and Price are fields Records Instances Each row in the entity table represents a specific instance of the entity For example a single row in the Customer entity table describes a particular customer Primary Key A unique identifier for each record within the entity This helps to distinguish one record from another preventing duplicate entries The primary key is crucial for relationships between entities Creating an Entity in Access 6 Creating an entity typically involves designing the table structure This includes Defining Field Names Clearly identifying the attributes you need to store eg EmployeeID Department Salary Specifying Data Types Determining the appropriate data type for each field eg Text Number DateTime to ensure data accuracy and consistency Setting Field Properties Adjusting properties like input masks validation rules and default values to enforce data integrity and userfriendliness Relationship Management in Access 6 Entities dont exist in isolation Access 6 allows you to establish relationships between different entities to represent realworld connections 2 OnetoMany Relationship One record in one entity can relate to many records in another For example one Order entity can contain multiple OrderItem records OnetoOne Relationship One record in one entity relates to only one record in another ManytoMany Relationship Multiple records in one entity relate to multiple records in another In Access 6 these relationships are usually implemented through a junction table Working with Entities in Access 6 Specific Tasks Data Entry Filling in the entity tables with information about individual records Querying Retrieving specific data from one or more entities using queries Access 6 offers various query types including simple selection queries and parameterized queries Updating Data Modifying existing data in the entity tables using update queries
