What is data warehousing?
A Data Warehousing is a process for collecting and managing data from varied sources to provide meaningful business insights. A Data warehouse is typically used by the experts of top engineering colleges in Jaipur to connect and analyze business data from heterogeneous sources. The data warehouse is the core of the BI system which is built for data analysis and reporting.
It is a blend of technologies and components which aids the strategic use of data. It is electronic storage of a large amount of information by a business which is designed for query and analysis instead of transaction processing. It is a process of transforming data into information and making it available to users in a timely manner to make a difference.
The decision support database is maintained separately from the organization’s operational database. However, the data warehouse is not a product but an environment. It is an architectural construct of an information system which provides users with current and historical decision support information which is difficult to access or present in the traditional operational data store.
How Data Warehouse Works?
A Data Warehouse works as a central repository where information arrives from one or more data sources. Data flows into a data warehouse from the transactional system and other relational databases.
Data may be Structured, Semi-structured, and Unstructured data. The data is processed, transformed, and ingested so that users can access the processed data in the Data Warehouse through Business Intelligence tools, SQL clients, and spreadsheets. A data warehouse merges information coming from different sources into one comprehensive database.
By merging all of this information in one place, an organization can analyze its customers more holistically. This help expert of best Private engineering colleges in Jaipur ensures that it has considered all the information available. Data warehousing makes data mining possible. Data mining is looking for patterns in the data that may lead to higher sales and profits.
Types Of Data Warehouse
Three main types of Data Warehouses (DWH) include the following:
1. Enterprise Data Warehouse
Enterprise Data Warehouse (EDW) is a centralized warehouse. It provides decision support service across the enterprise. It offers a unified approach for organizing and representing data.

In ODS, Data warehouse is refreshed in real time. Hence, it is widely preferred for routine activities like storing records of the Employees.
3. Data Mart
A data mart is a subset of the data warehouse. It is especially designed for a particular line of business, such as sales, finance, sales or finance. In an independent data mart, students of engineering colleges Jaipur can collect data from sources.
