This change birthed various specialized databases like columns for numbers, key-values for simple info, and graphs for relationships. What Is a Database? Now, it's different. The rise of big data and NoSQL changed the game.
From the engineering perspective, prompt engineering involves fetching and formatting external context from the session state, a database, or even integrating with a vector databasedesigned specifically for such use cases. The goal of the Spider challenge is to develop natural language interfaces to cross-domain databases.
Data normalization is also an important part of databasedesign. Data in a database is organized by normalizing it. It would be perfectly acceptable for a user to search through the Customer database to find a specific customer’s address. Data Normalization: How Does it Work?
