Abstract
A Relational Schema Definition (RSD) language that uses metadata of the relational database to generate an implementation-neutral or implementation-specific format that represents the precise database structure and data. The RSD language is a declarative description language such that an RSD file can then be used offline in a disconnected environment to reconstruct and use the database.

A method of representing a relational database, comprising:
- accessing relational schema information of the relational database;
- and
- generating declarative description data of the relational schema.
A method of representing a relational database, comprising:
- accessing metadata of the relational database;
- generating physical data from the metadata according to a declarative description language;

- and
- storing the physical and logical information in a data file.
A system that facilitates representing a relational database in a different format, comprising:
- means for accessing metadata of the relational database;
- means for generating physical data from the metadata according to a declarative description language;
- means for generating logical data by annotating the physical data using the declarative description language;
- and
- means for storing the physical and logical information in a data file.
