A database is considered self-describing because it contains metadata that describes its structure and organization. This metadata includes information about the tables, columns, data types, relationships, and other properties of the database. This allows users and applications to understand and interact with the database without needing external documentation.

What are the three design goals for relational databases and explain why each is desirable.?
Data integrity: Ensuring that data stored in the database is accurate and consistent by enforcing constraints, such as unique keys and foreign keys, to prevent invalid data. Scalability: Allowing the database to efficiently handle growing amounts of data and user load by optimizing data storage, indexing, and query performance. Maintainability: Simplifying the process of database maintenance, updates, and modifications by using normalization, clear data modeling, and documenting database structures.
Why are entity integrity and referential integrity important in a database?
Entity integrity ensures that each row in a table is uniquely identified, typically through a primary key, thus maintaining data accuracy and consistency. Referential integrity ensures that relationships between tables are maintained, preventing orphaned or inconsistent data, and promoting data integrity throughout the database. Both are essential in preventing data discrepancies and ensuring data quality in a database.

What is the difference between an operational and a transactional database?
The difference is not so much in the database itself but with the application that uses it. An operational application does all database queries/updates in a single one-and-done manner. Transactional applications have multiple steps that are considered a single unit and may involve dozens of database operations that must all be completed before any are finalized. Otherwise, the entire transaction is rolled back.
