Database

• Description: A common way to organize original source material in a database structure. It is irrelevant whether the data is numeric or graphic or computer files. Web-based methods have been developed to manage database online. Data mining techniques are useful in retrieving information from huge databases – several techniques are developed in order to find appropriate results and quick solutions with efficient search algorithms. Database store raw data and we need data mining (DM), because of its help useful information can be gathered from data. When data are transformed into knowledge, DM is a significant step in this process.
