The data type of the Variable determines/indicates the type of data that can be stored in a field/variable
The data type of a field. A field is basically a column in a table (stored as part of a database). Such a column can be of different types; the type determines what sort of data can be stored in the column. Typical types include numeric (accepts numbers), alphanumeric (accepts any character; typically used for text), date, boolean (only accepts true or false), and others.
Yes, you are right, every member (or field) of a structure does have a data type.
Example:
struct foobar {
int foo;
double bar;
};
we can store an object type data into a field.
Data Type indicates the type of data that can be stored in a field.
The field's type specifies what kind of data it may contain.
data type
In Access and in databases in general each field in a database table is of a certain data type. The data type determines what type of data a field can hold. A field of the text data type can hold text, a field of the number data type can hold numbers and a field of the data/time data type can hold date and time values.Access actively checks what type of data is entered into a field and Access will disallow the entry of data into a field that doesn't conform to the field's data type. Access won't allow you to put text into a field of the Number data type, for example.So, data types are a way to restrict the entry of data into a field. Internally, the database uses different strategies for the storage and retrieval of different data types.
Data Type defines the type of data that will be stored. Example : int, byte, short etc

If you set a field as that data type, such as for a website, then you can type in a valid address into the field and it will be stored as a hyperlink.There is a hyperlink data type.

data type
The data type of a field determines the kind of data it can contain. For example, a field with a data type of "Text" can contain letters and numbers, while a field with a data type of "Number" can only contain numerical values. The data type is set when designing the database schema.
A field's data type specifies the kind of data it can contain, such as text, numbers, dates, or Boolean values. This helps ensure data integrity by restricting what type of data can be entered into that field, preventing errors and inconsistencies in the database. Choosing the appropriate data type for each field is important for accurately storing and organizing data.

Text data
Changing the data type of a field can lead to data loss or data corruption if the new data type cannot accommodate the existing data. It can also affect any queries, reports, or applications that rely on the field's data type, potentially causing errors or unexpected behavior. It is important to carefully assess the impact and make any necessary adjustments to ensure data integrity before changing a field's data type.
What characteristics could a database field have, such as data type, field name, field size and field format?
