Question

Quizplus · Accepted Answer

Data types in a DBMS help allocate appropriate storage space for each data element. For example, a char(10) data type will take up 10 bytes of storage, whereas a float data type will take up 4 bytes of storage. This helps optimize storage and improve performance of the DBMS by minimizing the amount of storage required for each data element. Data types do not help present data, format data, eliminate data duplication, or retrieve information.
