Data centralization is vital for maintaining data integrity, ensuring that the data is accurate, complete, and consistently stored across a database. It improves efficiency, consistency, and comprehensibility of data storage, and facilitates better data management in digital databases. Option 4 is the answer.Data centralization is necessary for maintaining data integrity. This concept is crucial in the realm of database management and data storage, ensuring that recorded information maintains its accuracy, completeness, and consistency across the database. Centralizing data prevents the issues of duplicity and inconsistency that can arise when data is scattered across multiple locations. For instance, when a customer's name is stored in one single location rather than being repeatedly entered in different tables, this decreases the chances of errors and variation, thus preserving the integrity of the data.Data integrity is also linked with data quality information, such as the accuracy and completeness of the data attributes. By centralizing data, we enhance the efficiency of data queries and comprehensibility of the database schema. A well-organized database with a centralized structure allows for faster data retrieval, reduced disk space usage, and a more organized storage system that is easier for users to navigate and understand.The process of data centralization coincides with the evolution from paper-based records to digital databases. In a digital realm, the need for physical file cabinets is reduced, and with the application of standardization, classification, and coding, data can be effectively managed and analyzed. Centralization aids in integrating data into online data management programs, allowing for improved access and maintenance of the databases....
