But with the information age, it was found Nolan model has its limitations, not only from the acceptance of computer technology development and to evaluate the level of computer management information system processes, and effective allocation of resources from the information and data to effectively manage , effective system integration, or even go from the specific implementation of enterprise information starting, so the industry appears generally accepted four-stage model of enterprise information, these four stages are: a single department of information, inter-departmental information technology, business level information technology, information industry chain level. The following table: see this four-stage model, are based on information technology enterprises in the process, companies can implement their own specific circumstances of information, step by step in accordance with the Nolan models do not have the six stages.

Data mining is in accordance with certain rules of the database and data warehouse of information in the existing data mining, excavation and analysis, from identifying and extracting hidden patterns and interesting knowledge, and use them to provide scientific basis for decision-makers. Data mining task is to find patterns from the data. There are many models, according to the functions can be divided into two categories: predictive (Predictive) model and describe the type (Descriptive) mode.
