  3. Features of Data Warehouse • Data Warehouse provides unique features for organizations to analyze large amounts of data. The features of Data Warehouse are as follows: • Integrated: Data Warehouse helps integrate the data from various sources such as files, transaction records, and RDBMS into a consistent form used for effective data analysis. The data available in the Data Warehouse should be analyzed and stored in the form of naming, coding, and formatting. • Non-Volatile: The data stored in the Data Warehouse should be in a Read-only form and should not be allowed to change. The Non-volatile data warehouse does not enable operational data updates such as updating, deleting, and inserting data in the Data Warehouse. • Subject-oriented: A subject-oriented data warehouse is designed to provide topic-wise information rather than the overall processes of a business. It often offers a clear and concise view of a specific topic, such as a customer, a product, or sales, as opposed to the ongoing activities of the entire firm. • Time-Variant: The data in the Data Warehouse is stored as a time variance that helps retrieve data from elements of time such as a week, month, or year. www.infosectrain.com | sales@infosectrain.com
