Answer:
true.
Explanation:
Why is it important to assign data types to fields in a table? Allowing large field sizes may cause a database to use more storage space than is necessary forthe data you want to store.
Every table in Access is made up of fields. The properties of a field describe the characteristics and behavior of data added to that field. A field's data type is the most important property because it determines what kind of data the field can store. This article describes the data types and other field properties available in Access, and includes additional information in a detailed data type reference section.
Data types can seem confusing for example, if a field's data type is Text, it can store data that consists of either text or numerical characters. But a field whose data type is Number can store only numerical data. So, you have to know what properties are used with each data type.
A field's data type determines many other important field qualities, such as the following:
Which formats can be used with the field.
The maximum size of a field value.
How the field can be used in expressions.
Whether the field can be indexed.
