CAS-Based Approach for Automatic Data Integration

Eli Rohn
2013 American Journal of Operations Research  
Research of automatic integration of structured and semi-structured data has not resulted in success over the past fifty years. No theory of data integration exists.  ...  To overcome the serious reverse salient the field and industry are in, it will be helpful if a data integration theory would be developed.  ...  The syntax is usually referred to as the Data Definition Language (DDL). A DDL specifies how to organize and intercomnect related elementary pieces of data into useable structures.  ...
