Question: Which of the following contains permanent data and gets updated during the processing of transactions?

Answer:

A master file is a type of computer file that contains primary, persistent, and central data for a specific application or system. It serves as a core repository of essential information that is regularly updated and maintained.

The characteristics of a master file include:

1. Primary Data: A master file contains primary data that is critical to the functioning of a particular system or application. It typically holds core information, such as customer details, inventory records, employee information, or financial data.

2. Persistence: Master files are designed to retain data over an extended period, allowing for long-term storage and retrieval of essential information. They are not intended for temporary or transient data.

3. Centralized: Master files act as a central repository of data, providing a single source of truth for the specific application or system. They ensure consistency and uniformity by consolidating and organizing relevant data in one location.

4. Regular Updates: Master files are subject to regular updates and modifications as new data is added, existing data is modified, or outdated data is removed. These updates ensure the accuracy and currency of the information stored in the file.

5. Integration: Master files often serve as a reference point for other files or components within an application or system. They can be referenced and utilized by other files or modules to provide a comprehensive and coherent view of the data.

Examples of master files include:

- Customer Master File: Contains information about customers, including names, addresses, contact details, and purchasing history.
- Product Master File: Stores details of products or items, such as descriptions, prices, quantities, and inventory levels.
- Employee Master File: Holds employee-related information, such as names, positions, contact details, salaries, and employment history.
- Financial Master File: Includes financial data, such as balance sheets, income statements, general ledger accounts, and transaction records.

Master files play a crucial role in maintaining the integrity and consistency of data within an application or system. They provide a foundation for various processes, reporting, and decision-making within organizations.
