What is contained within a module in a database?

A module in a database typically comprises a collection of declarations, statements, and procedures that contribute to the functionality and behavior of the database system. This can include code that defines how data should be manipulated, retrieved, and stored. The organization of these elements as a cohesive module allows for more efficient programming practices, as developers can encapsulate specific functionalities within modules, facilitating reuse and maintenance.

For instance, a module may contain functions to add or modify records, queries to retrieve data, and procedures to enforce data integrity. This structural approach enhances modularity in coding, enabling easier debugging and scalability of database applications as the system evolves.

While other choices touch on aspects related to database interaction and reporting, they do not encapsulate what is fundamentally included in a database module. Data entry screens facilitate user interaction but are not part of the module's code framework itself. Rules structured as If/Then statements may be used in some scenarios, but they are typically part of a logic layer rather than a module itself. Summarized reports represent outputs derived from data analysis and are not contained within the module; they are the results produced after executing procedures defined within the module.
