....this materialized view algorithm is more powerful then the simple condition 20 compilation algorithm presented in Section 1.1.1. The disadvantage of this algorithm is the added load of maintaining one more materialized view. The presented in this section material is from [0zVa99] SiVa84] and [Cive88] 5. Integrity Constraint Restoring Algorithms In a distributed database constraints may often be violated. This can be a result of allowing updates to the database that violates the integrity constraints, or as a result of constraints imposed on materialized views. 5.1. The algorithm Let 27 ....

....work we plan on this topic. 6 2. REVIEW OF PAST WORK There has been a large amount of work in the integration area: a detailed survey by Batini et al. 2] discussed twelve methodologies for view or database integration (or both) and new contributions continuously appear in the literature ([5, 7, 12, 17, 19, 21, 22, 25, 36, 41] and many more in [20] An analysis of current methodologies shows a prevalent dichotomy of approach. Most of view integration papers attempt to establish a semi automated technique for deriving an integrated schema from a set of integration assertions relating corresponding objects in the ....

....In [20] a method for identifying view similarities based on using a semantic dictionary and a taxonomy structure is proposed while [11] uses conceptual graph theory to support view integration. Using concepts from the field of artificial intelligence to support view integration has also been done. [6] proposes an expert system approach to view integration. In [5] experiences are reported in using linguistic tools, such as thesauri and information retrieval techniques to build dictionaries and to support the view comparison process. In [9] fuzzy and incomplete terminological knowledge together ....

....data (and programs) not just with metadata in the views. There has been a large amount of work in the integration area: a detailed survey by Batini et al. 2] discusses 12 methodologies for view or database integration (or both) and new contributions continuously appear in the literature [3] [4] [5] 6] 7] 8] 9] 10] As view integration is a process in which knowledge of the semantics of data is needed, it is no surprise that most of the current methodologies rely on a semantic data modelling approach. In particular, the Entity Relationship (ER) approach, in its various extended ....
