Object-oriented Data Warehouse Modeling Method

The data warehouse can help the policy makers of the enterprise predict and analysis the enterprise forward direction. It has been more widely used and has been successful in many areas. But reviews the current situation in construction state of the data warehouse, among them the most data warehouses is a failure .Trace it to its cause, may not be attributed the failure to the inherent features or decision support of the data warehouse, but caused by method to establish.This article is based on object-oriented modeling data warehouse technology.First of all, after ABC of the data warehouse of the introduction, we direct against the application background of the data warehouse, should adopt the spiral mode that is develop flexibly, reflect accurate and carry on systematic research and development. Because the data warehouse is a subject-oriented, it should be conducive to the process of its development methods, the object model based on object-oriented technology can clearly reflect object attributes, behavior, and the relationship between them, it is also necessary for data warehouse modeling, so in modeling of the data warehouse, it was object-oriented modeling method that was adopted.The concrete application of the Object-Oriented Modeling in the data warehouse will be take owing-fee subject in telecommunications as an example. We have carried on more overall analysis and studied in owing-fee subject, and then set up the model of analyzing that model is the understanding of present environment and is a foundation for further design, In modeling, receive the information collected in models and analytic process, having expanded models of analyzing in an all-round way; develop a comprehensive model produced object model. Object Model contains all the attributes and behaviors related to the system, also have how a single object related with the others. Then lasting is the work that is the object mapped to the database tables operation. Discussion on object-oriented modeling of the data warehouse model and object model, we can achieve the real model that is real structure of the database, which is the last part of the design model.
