An analogue database refers to a system that stores information in a non-digital format, often using physical media such as paper, microfilm, or magnetic tape. These databases rely on traditional methods of data organization and retrieval, making them less efficient and harder to manage compared to digital databases. While they were commonly used in the past, analogue databases are increasingly being replaced by digital systems that offer greater accessibility, speed, and data manipulation capabilities.

Yes, Data Definition Language (DDL) statements, such as CREATE, ALTER, and DROP, typically result in an implicit commit in most relational database management systems. This means that once a DDL statement is executed, it is automatically committed, and the changes cannot be rolled back. Consequently, it's essential to ensure that DDL operations are performed with caution, as they can permanently alter the database schema.

When a filter is applied to a database, records that do not meet the specified criteria are excluded from the results returned by the query. These records remain intact in the database but are simply not visible in the output of the filtered search. This allows users to focus on relevant data without altering or deleting any underlying records. The original dataset remains unchanged, preserving all information for future queries.

Database management plays a crucial role in treating data as a vital business resource by ensuring data integrity, security, and accessibility.
