In the stream of Computer Science, an enterprise data warehouse or simply data warehouse (that is, EDW or DW) is a database mainly employed for reporting and data examination. This is a central storage area of data which is made by integrating the data from one or lots of disparate sources. Data warehouses store the current and as well chronological data and are utilized for making trending reports for the superior management reporting such as yearly and monthly.
The data warehouse is an incorporated, non-volatile, time-variant and subject-oriented data collection in support of management's decision making method.
Subject-Oriented: The data warehouse can be employed to examine the particular subject region. For instance, sales can be a precise subject.
Integrated: Data warehouse incorporates data from abundant data sources. For instance, source A and source B might have distinct manners of recognizing a product, although in a data warehouse; there will be a single method of recognizing the product.
Time-Variant: The chronological data is kept in the data warehouse. For instance, one can regain data from 3 months, 9 months, 24 months, or even prior data from the data warehouse. This disagrees with a transactions system, where recurrently the latest data is kept.
Non-volatile: Once the data is in data warehouse, it will not convert. Thus, chronological data in the data warehouse should not be changed.
Data Warehouse is the major seat of the Computer Science. Virtual classroom which is Computer Assignment Help is a place where the students can correlate with online assistance for computer assignments and queries and students can get different kinds of help in many subjects and be benefited by improving the corresponding grades.
