Searching a database involves looking for specific information or records within a structured collection of data. This usually involves using keywords, queries, or filters to retrieve relevant results that meet the search criteria. The goal is to efficiently locate and retrieve the desired information from a large dataset.
The database schema is the description of the database. It defines how the database is set up and what data it is to contain and control. This description is given to the DBMS to manage the data. The database state is an image of how the database looks at any given time. The database schema is set unless you change how the database is structured. The database state will change whenever new data is entered into the database and the database is updated.
