b) Define custom data types
c) Modify the existing data types
d) Switch to a different database system

Answer 1

You can obtain data types other than predefined ones by defining custom data types.

Step-by-step explanation:

If you are using a database type other than the ones that have predefined data types, you can obtain those data types by defining custom data types. This involves creating new data types that are tailored to your specific needs. When defining custom data types, you can specify the size, format, and range of values that the data type can store.

For example, let's say you are using a database system that doesn't have a data type for storing IP addresses. You can define a custom data type called 'IP' that can store IP addresses and specify the necessary validation rules.

By defining custom data types, you can extend the capabilities of your database system and cater to specialized data requirements.
