Final answer:
Database software is used when there is a need to see table relationships and sort data by custom fields. It allows for efficient organization and management of large amounts of data.
Step-by-step explanation:
Database software is used instead of spreadsheet or word processing software when there is a need to see table relationships and sort data by custom fields.
Unlike spreadsheets or word processors, database software allows for the efficient organization and management of large amounts of data. It enables the creation of complex data structures, establishes relationships between tables, and provides powerful querying and sorting capabilities.
For example, a company may use database software to store and retrieve customer information, track inventory, and generate reports based on specific criteria.
