Business administration and complicated decision making fully rely on the accurate information gathered from the whole enterprise on the basis of data integrity and information integrity . As far as data integrity is concerned, the cascade update functionalities provided by database systems are often used for the data integrity maintenance. Meanwhile, Active Database mechenisms provided by some specific database firms are often used to maintain information integrity, and the logic of information integrity mainenance program are designed for specific enterprises under specific specification proposed by different database system providers. The differences of enterprise business logic and program implementation specification cause that all the information integrity maintenance programs are lack of portability, genericity, configurability and reusability, and the unacceptable high cost of system development and mainenance. In this thesis a generic information integrity maintence model is proposed and can be applied to every kind of enterprises or organizations. Then, according to the model, an information integrity maintenance component model is developed, with the property of business logic configurability, database portability that can facilitate the construction of information integrity maintenance mechanism, providing a simple and flexible information integrity maintenance solution for information system developer and maintainer
