A relation schema is the logical definition of a table-it defines what the name of the table is, and what the name and type of each column is. It's like a plan or a blueprint. A database schema is the collection of relation schemas for a whole database.A table is a structure with a bunch of rows (aka tuples), each of which has the attributes defined by the schema. Tables might also have indexes on them to aid in looking up values on certain columns.A database is, formally, any collection of data.chema Objects. A schema is a collection of logical structures of data, or schema objects. A schema is owned by a database user and has the same name as that user. Each user owns a single schema.
