In the world of computing, data warehouse is defined as a system that is used for data analysis and reporting. Also known as enterprise data warehouse, this system combines methodologies, user management system, data manipulation system and technologies for generating insights about the company. Considered as repositories of data from multiple sources, data warehouse stores both current and historical data. They are then used to create analytical reports that can either be annual or quarterly in nature.

These report are then used by companies to make detailed sales analysis and marketing campaigns that can effectively take them to the next stage of growth. Before the data is used for data warehouse reporting, it may be used for operational data store as well. Many big companies use separate warehouse to collect and maintain data in an effective manner.
How did data warehouse originate?
Data warehousing dates back to the late 1980s when Barry Devlin and Paul Murphy from IBM developed business data warehouse. In actuality, data warehouse was developed to provide an architectural model for the flow of data, specifically from from operational systems to decision support environments. By addressing problems related to the flow, data warehouse tried to support multiple environments in an effective manner. Thus by introducing the concept of data warehouse, Bill and Ralph were considered as the pioneers of data warehouse. This means that before the concept of data warehouse, data storage and synchronisation was not conducted. Post the development of business data warehouse, data warehouse has come a long way and are today an integral part of companies and economies around the world.

Before the development of data warehouse, secondary storage was considered as the best way to save data. However, data warehouse supports integration, cohesiveness and multi-application of data, making them a more suitable choice. This is because data warehouse helps to preserve data for future use as well. As data in a warehouse is secure, data warehouse is one of the effective methods to store data for future use.
Data warehouse allows companies to store large volumes of data
Today the data available to companies is almost limitless. And data warehouse is more than capable of meeting this challenge as the size of the warehouse can be increased depending on the amount of data. Different organisations have different amounts of data that they would want to save for future use, so data warehouse is one of the perfect ways to meet that requirement in an effective manner.
Data warehouse is accurate and grounded
Data in a data warehouse is completely accurate and grounded, as it contains all techniques and theories. As a lot of companies, depend on data insights to take future decisions, this is an extremely important feature. If data is incorrect, it can affect the progress and growth of the company, As a number of technologies is involved in protecting data in warehouse, companies can be assured that the data they have is effective, discrete and multi dimensional.
Data warehouse is the future of all companies, be it big or small
Since data warehouse was officially introduced in the year 2002, it has steadily grown in popularity and has become an integral part of many companies and brands. As many companies use data warehouse to preserve and gain insights about data, there are many advancements in this field by engineers that are making data warehouse more progressive and advanced.
