Difference between meta data and data dictionary?
Metadata is data that provides information about other data, such as the structure, format, and relationships of data elements. A data dictionary, on the other hand, is a centralized repository that defines and describes the data elements within a database, including their definitions, attributes, and relationships. In summary, metadata is broader and encompasses various types of information about data, while a data dictionary specifically focuses on defining and documenting the data elements within a database.
What is the primary difference between global and universal groups?
Universal groups add more data to the global catalog.
What is difference between data dictionary and database schema?
A data dictionary is a collection of metadata about the data elements in a database, where as, a database schema is a design blueprint for how data is structured and organized within a database. The data dictionary describes the data, while the schema defines how the data is stored.
What is the difference between active and passive data dictionary?
Active data dictionary is constantly updated and reflects real-time changes within a database or system, while passive data dictionary is static and does not change unless manually updated. Active data dictionary is dynamic and integral to system operations, providing current information about data elements, relationships, and structures. Passive data dictionary is more archival in nature, serving as a reference for historical data definitions and structures.
Difference between catalog and schema?

What is the difference between a model-driven and data-driven DSS?
A model-driven DSS relies on mathematical or statistical models to analyze data and make predictions, while a data-driven DSS uses historical and real-time data to generate insights and support decision-making without relying heavily on predefined models. Model-driven DSS are more structured and use algorithms to process data, while data-driven DSS focus on exploring patterns and trends in data to inform decisions.
