The Ultimate Guide to Data Integration

In a post-covid world, where digital channels have become the primary source of interaction between businesses and their customers, the importance of data integration has grown multifold. It enables businesses to obtain a complete view of their data and gain insights which would be impossible when organizations store data in silos. So, what is data integration, and what are its benefits? Let’s explore these and more.

What is Data Integration?

As organizations collect data from different sources and in different forms, they need to combine them and create a unified and comprehensive view of the data. Data integration is the process of combining raw data. Here, data from disparate sources—including databases, applications, files, and APIs—are brought together and consolidated to generate a single view, and create meaning out of raw data for different business processes. The primary goal of data integration is to ensure the raw data’s accuracy, consistency, and relevance.

How Does Data Integration Work?

Data integration is a multi-step process that works depending on the data sources, the tools and technologies used, and the type of integration an organization needs. Here is the basic step-by-step guide to data integration that most organizations follow.

• Identifying Disparate Data Sources

The first step to data integration is identifying disparate data sources. These sources can include databases, files, web services, cloud-based systems, or other data sources.

• Data Extraction

Once data scientists identify different data sources, they extract data from different sources. Data is extracted using different processes, including SQL queries, APIs, or other methods relevant to the source and data type.

• Data Transformation

This is one of the most vital steps in the process. The extracted data is transformed to create a common, easily integrable format. Different data types are converted at this stage into a single format, standardized, and normalized to achieve a unified view.

• Data Mapping

Post data transformation, organizations move to the next stage – data mapping. Data scientists turn different data elements into a common schema in this stage. This step maps the data into a common model.

• Data Loading

The data is now in a common format and has been mapped, and it is ready for loading into a target system. The target system can be a data warehouse, data lake, or other data repositories. ETL (Extract, Transform, Load) tools or other data integration software help in data loading.

• Data Cleaning and Validation

Since businesses collect from different sources, there is a chance of duplication and lack of accuracy. Data cleaning and validation help overcome this challenge, improving accuracy and consistency.

• Data Monitoring

Data integration isn’t a one-time gig but an ongoing process. Hence, it is important to monitor the data and the process to ensure the target systems are fed with accurate and up-to-date data. Implementing processes such as data governance and data lineage helps in the endeavor.
