This step reflects the information and analytical characteristics of the data warehouse. Translate this into the physical model. This reflects the changes necessary to reach the stated performance objectives. The business Model Identify the data structure, attributes and constraints for the clients data warehousing environment. Stable Optimized for update Flexible business Model As always in life, there are some disadvantages to 3NF: Performance can be truly awful.

Most of the work that is performed on denormalizing a data model is an attempt to reach performance objectives. The structure can be overwhelmingly complex. We may wind up creating many small relations which the user might think of as a single relation or group of data. Structural Dimensions The first step is the development of the structural dimensions. This step corresponds very closely to what we normally do in a relational database. The star architecture that we will develop here depends upon taking the central intersection entities as the fact tables and building the foreign key primary key relations as dimensions.

Statistical Analysis, data discovery. (decision support, artificial intelligence and expert systems). Olap, data visualization, hardware budget, a typical startup warehouse project allocates more than 60 percent of using its budget for hardware and software to the creation of a powerful storage component, spending just 30 percent on data mining and user access technologies. Systems Analysis Budget Budgeting for systems analysis and development, however, follows a very different pattern. More than 50 percent of development dollars are spent on building acquisition capabilities, 30 percent fund the development of user solutions and 20 percent are dedicated to the creation of databases in the storage component. Design Issues Relational and Multidimensional Models Denormalized and indexed relational models more flexible multidimensional models simpler to use and more efficient Star Schemas in a rdbms in most dissertation companies doing rolap, the dbas have created countless indexes and summary tables in order to avoid I/O-intensive. As the indexes and summary tables proliferate in order to optimize performance for the known queries and aggregations that the users perform, the build times and disk space needed to create them has grown enormously, often requiring more time than is allotted and more space. Building a data warehouse from a normalized Database The steps develop a normalized entity-relationship business model of the data warehouse. Translate this into a dimensional model.
