==Databases vs schemas (terminology)==
{{Original research|section|date=June 2010}}
The [[SQL]] specification defines what an "SQL schema" is; however, databases implement it differently. To compound this confusion the functionality can overlap with that of a parent database. An SQL schema is simply a [[namespace]] within a database; things within this namespace are addressed using the member [[operator (programming)|operator]] dot "
A true [[fully qualified name|fully (database, schema, and table) qualified]] query is exemplified as such:
Both a schema and a database can be used to isolate one table, "foo", from another like-named table "foo". The following is pseudo code:
* {{code|SELECT * FROM database1.foo|sql}} vs. {{code|SELECT * FROM database2.foo|sql}} (no explicit schema between database and table)
* {{code|SELECT * FROM [database1.]default.foo|sql}} vs. {{code|SELECT * FROM [database1.]alternate.foo|sql}} (no explicit database prefix)
The problem that arises is that former [[MySQL]] users will create multiple databases for one project. In this context, MySQL databases are analogous in function to PostgreSQL-schemas, insomuch as PostgreSQL deliberately lacks off-the-shelf cross-database functionality (preferring multi-tenancy) that MySQL has. Conversely, [[PostgreSQL]] has applied more of the specification implementing cross-table, cross-schema, and then left room for future cross-database functionality.
MySQL aliases ''schema'' with ''database'' behind the scenes, such that
Oracle has its own spin where creating a user is synonymous with creating a schema. Thus a database administrator can create a user called PROJECT and then create a table PROJECT.TABLE. Users can exist without schema objects, but an object is always associated with an owner (though that owner may not have privileges to connect to the database). With the 'shared-everything' [[Oracle RAC]] architecture, the same database can be opened by multiple servers concurrently. This is independent of replication, which can also be used, whereby the data is copied for use by different servers. In the Oracle implementation, a 'database' is a set of files which contains the data while the 'instance' is a set of processes (and memory) through which a database is accessed.
Informix supports multiple databases in a server instance like MySQL. It supports the
PostgreSQL and some other databases have support for foreign schemas, which is the ability to import schemas from other servers as defined in [[SQL/MED|ISO/IEC 9075-9]] (published as part of [[SQL:2008]]). This appears like any other schema in the database according to the SQL specification while accessing data stored either in a different database or a different server instance. The import can be made either as an entire foreign schema or merely certain tables belonging to that foreign schema.<ref>{{Cite web
