Extension language is implemented in the data design language (DDL) to incorporate tables, entities (and views) having custom-defined/semantic structure, rather than being limited to primitive types (e.g. flat tables as in standard SQL). The extension language includes an indication that a query is to include all active elements for each table extension or entity extension that is active. The extension language can be chained to extend a table or entity that has been extended."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Core data services extensibility for entity-relationship models","description":"Embodiments extend the relational model and query language to recognize features of tables and higher level entity-relationship models (ERMs).
