How does Data Warehouse work?

Data warehouse fetches data from apps and systems; then data goes through various formatting and importing processes to match the data that has already been stored in the data warehouse.

The data may be stored in:

  • Structured
  • Semi-structured and
  • Unstructured form.

The data is processed, transformed, and ingested in the data warehouse through Business Intelligence tools, SQL clients, and spreadsheets. Now the processed data gives meaningful business insights to help companies make better decisions.

How does Data Warehouse work?

Types of Data Warehouse

Three main types of Data Warehouses are:

Enterprise Data Warehouse (EDW)

Enterprise Data Warehouse is a centralized warehouse that provides decision support service and a unified data representation approach. This classifies data according to the subject and gives access according to those divisions.

Operational Data Store

Operational Data Store, which is also called ODS, is nothing but data stores required when neither Data warehouse nor OLTP systems support organizations reporting needs. In ODS, the Data warehouse is refreshed in real-time. Hence, it is preferred for routine activities like storing records.

Data Mart

A data mart is a subject-oriented database that is specially designed for a particular line of business, such as sales, finance, sales, or finance. In an independent data mart, data can be consolidated directly from data sources.

General stages of Data Warehouse

Components of Data warehouse

Three components of Data Warehouses are:

Load Manager

The load manager is also called the front component that performs all the operations associated with the extraction and load of data into the warehouse. From transformations to creations of data for entering into the Data warehouse these operations.

Warehouse Manager

The warehouse manager performs operations associated with the management of the data in the warehouse. For instance, analysis of data to ensure consistency, creation of indexes and views, generation of denormalization and aggregations, transformation and merging of source data, and archiving and backing-up data.

Query Manager
