What is a data type? Describe the relationship between a field and a data type. What are some rules for selecting appropriate data types for fields when designing tables in Access?
A data type is a classification of data based on the nature of the data being stored. In computer science and programming, data types are used to define the type of data that can be stored in a variable or a field. In the context of databases, a field is a column in a table that represents a specific type of data. The data type of the field determines the type of values that can be stored in that column. For example, a field with a data type of “integer” can only store whole numbers, while a field with a data type of “text” can store any combination of letters, numbers, and symbols. The relationship between a field and a data type is that the data type defines the type of data that can be stored in the field. When designing tables in Access, it is important to select the appropriate data types for the fields to ensure that the data is stored in a consistent and efficient manner.
