What is meant by database architecture?

Database architecture refers to the structural design of a database system that outlines how data is stored, organized, and accessed. It encompasses the relationships between different data entities, defines the database schema, and includes considerations for performance, scalability, and security. The architecture serves as a blueprint that informs how various data components will interact, ensuring that the database meets the specific needs of the application and its users.

In this context, the correct answer emphasizes the importance of planning and structuring data efficiently, which is crucial for performance and usability. Effective database architecture allows for quick retrieval of information, proper data integrity, and efficient data updates, all of which are vital in a startup environment where rapid growth and flexibility are often necessary. Each choice addresses different aspects of software and systems design, but only the one focused on data storage and organization aligns directly with the definition of database architecture.
