ER-SPML (Entity Relationship-Stored Procedures Meta Language) is proposed to be independent by RDBMS team players in idea to support their own SQL dialects on Platform Specific Language, versus the conceptual level Platform Independent Language. The metalanguage proposes a new operation called Stored Procedures and the language behind him in idea to be platform independent in relation with SQL dialects and their Procedural Languages. The concept of stored procedures operation is abstract, helps in syntactic and semantic modeling, and is required in physical implementation. A stored procedures operation along with his language captures the syntactic and semantics of an RDBMS schema in his dynamical evolution, not in a statical way like ER diagram. An case study of database design with ER-SPML and description using the metalanguage and the diagrammatic technique is given.
