Résumé

Foundation for Future Database Systems: The Third Manifesto is a proposal for the future direction of data and database management systems (DBMSs). It consists of a precise, formal definition of an abstract model of data, to be considered as a blueprint for the design of a DBMS and a database language. Among other things, it provides a rock-solid foundation for integrating relational and object technologies.
The proposed foundation represents an evolutionary step, not a revolutionary one; it builds on Codd's relational model of data and on the research that sprang from that work. It also incorporates a precise and comprehensive specification for a method of defining data types, including a comprehensive model of type inheritance, to address a lack that has been observed by many authorities; thus, it also builds on research in the field of object orientation. With a sound footing in both camps of the object/relational divide, therefore, the Manifesto is offered as a firm foundation for the DBMSs of the future.
Significant features of this new edition include:

Major extensions to the inheritance model
Significantly improved language proposals
Improved discussions of read-only vs. update operators, selectors, THE_ operators, tuple types vs. possible representations, grouping and ungrouping, first normal form, assignment, constraints, predicates, and many other topics
All SQL discussions upgraded to the level of the new SQL:1999 standard
Several new appendixes
