What Is Data Integration?

There is a lot of data in the world, and it can be difficult to make sense of it all. Keep reading to learn more about data integration and how it can be used to make better decisions.

What is data integration?

Have you ever searched “what is data integration“? Data integration is the process of combining data from multiple sources into a single, unified view. This can be done for a variety of reasons, such as to improve decision-making, simplify reporting and analysis, or create a more complete picture of the business.

There are several different methods for integrating data, each with its own advantages and disadvantages. The most common approach is to use a data warehouse or data mart. A data warehouse is a centralized repository for all corporate data, while a data mart is specifically designed to support decision-making. Other methods include using an enterprise information management (EIM) platform or ETL (extract, transform, load) software. EIM platforms provide a comprehensive solution for managing and integrating all types of corporate information. ETL software extracts the data from source systems and loads it into the target system. It then cleans and transforms the data to ensure that it is compatible with the target database structure.

How does data integration work?

Data integration tools and techniques can help to overcome these challenges by identifying and resolving discrepancies between the data sources. Data integration is often used to support business intelligence (BI) initiatives. BI applications require accurate and timely data to make sound decisions, and data integration can help to ensure that this data is available. By integrating data from multiple sources, BI applications can provide a more complete picture of the business landscape, which can help organizations make better strategic decisions.

There are a variety of tools and techniques that can be used for data integration. Along with EIM platforms and ETL software, some common data integration approaches include:

  • Data federation. In this approach, federated search engines are used to combine information from multiple sources. This allows users to search across all of the data stores simultaneously, providing a single view of all the relevant information.
  • Master Data Management (MDM). MDM solutions focus on managing master data records across multiple systems. Masterdata includes key information such as customer or product master files that need to be synchronized across systems for accurate reporting or analysis.
  • API Integration. APIs provide a way for systems to interact with each other programmatically. By using APIs, businesses can create integrations between their systems without needing to rely on manual processes or custom scripts.
  • Online Analytical Processing (OLAP). OLAP allows you to quickly analyze large volumes of data by creating cubes that contain pre-calculated summaries of the data. Cubes can be sliced and diced in various ways to answer business questions quickly and easily.

How can you prevent data integration failures?

Data integration failures can be prevented by following a few key guidelines. You should ensure accurate and clean data. To ensure accurate and clean data, it is important to have a data governance plan in place. This includes creating standards for data quality, defining roles and responsibilities for managing the data, and establishing processes for correcting errors. You should also design an effective ETL process so it can handle errors without any issues. Lastly, you should test the data before it is integrated into the main system, and have a plan for dealing with errors.


Overall, data integration is an important process for businesses as it allows them to combine data from different sources into a single repository. This can help businesses to make better decisions, improve their operations, and identify new opportunities.
