To date, the merits of data warehouse integration have been the subject of intense scrutiny by organisations at all levels. Back in 2018, for instance, the well-known Google company developed the Data Transfer Project. The central task of the project became the need for data warehouses integration between online service providers at any time. Info storage and integration is an extremely important issue, as the report by Statista confirms: as of 2022, more than 60% of all corporate data was stored in the cloud. 

Undoubtedly this indicator will be growing, which invariably leads to the need for data integration. But first things first. In this article, we’ll look at what data warehouse integration is and what the benefits for businesses are.


Data warehouse is a technique that contains large amounts of corporate information. Such systems are specifically designed to support business intelligence (BI) activities such as reporting, analysis, and decision-making. We’re talking about a relational database that stores info from numerous sources and transforms them into a format suitable for querying and analysis.

Data warehouses typically follow a schema-on-write approach, which means that data is organised into a specific schema before loading into the base. Thereby making it possible to report and analyse much faster.


Data warehouse integration is the process of merging pieces of information from multiple sectors into a single, coherent data storage. It encompasses bringing together information from various systems, applications, databases and other sources and converting it into a consistent and standardised format. Such databases can be accessed by any department within the organisation and the data can easily be structured into spreadsheets or tables for analytics purposes.


The integration process is complicated and typically involves several levels such as extracting, transforming, and loading data into the warehouse. It may include cleaning and restructuring, eliminating inconsistencies, and applying business rules to ensure data accuracy and relevance. Let’s take a look at the process in sequence. 


The procedure begins with extracting materials from source systems such as transactional databases, spreadsheets, flat files and web services. Information is usually retrieved using Extract, Transform, and Load (ETL) tools, which are designed to pull it from various sources and convert into the desired format.


The pulled up materials are then converted according to the requirements of the data warehouse. This step may involve cleansing and restructuring, eliminating inconsistencies and duplicates, and applying business rules and logic. 


The converted dataset is then uploaded into the warehouse. At this stage, the data is inserted into the relevant tables and columns of the data warehouse.


Once information, it is consolidated into a single, coherent data warehouse. This involves ensuring that data from different sources is consistent and standardised.


Finally, the dataset is checked to ascertain that it is accurate and complete. This step is needed to ensure that there are no discrepancies or loss of data.


Data integration opens up plenty of new opportunities to upgrade a company’s technical infrastructure. The checks and balances during the process help avoid potential human error. The system also facilitates immediate access to data for all employees, reducing processing time. These and many other innovations could be embedded in your business environment today – don’t delay! 


By centralising and establishing a consistent ruleset for data entry, the associated warehouse can help upgrade the overall quality of an organisation’s databases. This, in turn, will help to tighten up decision-making and business efficiency.


Such systems offer access to large amounts of historical databases, allowing entities to perform sophisticated analytics and gain deeper insights into business operations. This can lead to more informed decision-making and better strategic planning.


Joining databases enhances the performance of business intelligence applications and other data-driven systems. By reducing the time and effort required to access and analyse, this association method leads to cost efficiency and increased productivity.


Data warehouse integration is essential today as it allows entities to aggregate materials from disjointed sources, gain an extended view of their operations and make better-informed decisions. It also empowers data analysts to access and analyse data more easily, free from the need of having to navigate through a variety of systems and info sources. Integration is especially significant for large retailers, who desperately require to navigate through thousands of products in different locations. Either for the telecommunications sector, for the ability to track client information, service packages, promotions and technical issues. Thus, data warehouse integration is the basis for a highly productive usage of info resources.
