The collection of information stored in a database at a particular moment is called a database snapshot. It provides a point-in-time view of the data captured during the snapshot creation. This snapshot can be used for reporting, analysis, or backup purposes.
A database that understands how information is connected is called a relational database. It organizes data into tables with rows and columns, and uses keys to establish relationships between different tables. This allows for efficient storage and retrieval of interconnected information.
