In database management systems, the term "Schema" refers to the logical design or structure of the database. It defines how the data is organized and how the relations among them are associated. It formulates all the constraints that are to be applied on the data.
An "Instance" is a snapshot of the data in the database at a given instant in time. It is the set of information inserted into the database at a particular moment.
