Data integration is crucial in today’s business world. Business data comes via many sources, from internal databases to clicks on a website. Being able to access all your data in one place helps your business make better, faster decisions. But how do you integrate all your data, and what’s the best way to do it? Here we discuss five data integration methods, how they work and why businesses continue to choose them.

1. Manual Data Integration

The most basic — yet in some ways the most heroic — of data integration techniques is manual integration. Manual data integration requires that your business employ a dedicated data engineer who individually manages and codes data connections in real-time. A data engineer has to make the right connection to each data source, clean and reorganize the data as needed, and manually transfer it to a desirable destination.


  • Absolute control over data integration and management
  • If an organization already has a data engineer or data management team, there are no additional costs associated with manual data integration


  • Other members of the business may find it hard to access or analyze data
  • Scalability is difficult without hiring more staff
  • Errors are likely with complex data connections or big data queries
  • Data engineers must individually and manually code connectors to different data sources every time a new system needs to be accessed

2. Data Integration with Middleware

Middleware, as the name suggests, is software that sits between applications to transfer data. A middleware data integration solution transfers data from a range of applications to databases. Usually automated, middleware can often perform the transformations that make data compatible with new systems. This helps if your business is moving from older legacy systems to a range of modern applications, and it creates a network of information accessible by anyone in your organization.


  • Your network systems should communicate better with effective middleware
  • Enterprise data automatically transforms and transfers in a consistent manner


  • Enterprises require a skilled developer to install and maintain middleware, which can increase operational costs
  • Not all systems are compatible with middleware

3. Uniform Data Access Integration (UDAI)

This method of integration focuses on displaying the data in a consistent format for ease of use while actually keeping the source data at its original destination. Think of it as a translation app for a multitude of languages that are actually dozens of unique sources of business data. Data replication occurs as you view it, but the data always remains at the original source.


  • A simple and unified view of data
  • Allows multiple systems or apps to connect to one central source
  • No high-storage requirement


  • Accessing data from within source systems causes frequent data access requests, which can put a strain on the data host systems, limit the functionality or lead to latency
  • Having multiple data access points can compromise data integrity and data quality

4. Common Storage Data Integration

As business data becomes more complex and abundant, the common storage option is an integration approach that many enterprises take. Similar in principle to uniform access, the information undergoes data transformation before it's copied to a data warehouse, so your systems only have to access one data source, not hundreds. Because the data is in one place and accessible at any time, you can run analytics and business intelligence (BI) tools as-is and when you need to. Common storage integration is the basis for many data warehouses, the common name for most modern data storehouses.


  • Less strain on data host systems, as it holds data sets in one destination
  • Uniform data appearance to streamline analytics
  • Higher data integrity
  • More opportunity for effective analytics


  • Costs for data storage could increase as data volumes bump up
  • Unless you use a third-party data warehouse, there are maintenance costs

5. Application-Based Data Integration Tools

Application-based integration software effectively locates, retrieves, and transforms your data, and then integrates it into your desired destination. This often involves automation, pre-built connections to a variety of data sources, and the ability to connect to additional data sources when necessary.


  • Seamless data transfer and exchange of information between different systems and destinations
  • Easy on resources thanks to automation
  • Scalable as the amount of data you consume increases
  • Simple to use and doesn’t always require a technical expert


  • If you are using on-premise software, you may need an expensive technical expert on-site and Data Integration offers an easy way to integrate and manage your business data. Our Extract, Transform, Load (ETL) data integration platform allows anyone, regardless of technical experience, to create effective data pipelines using our low-code platform.

The ETL process and the huge number of integrations we support make an essential part of your data stack for any number of use cases. Fully elastic and scalable, takes the hard work out of data integration and consolidation, leaving you free to work with high-quality, accurate data for better business analytics and profit-boosting insights. Schedule a conversation to discuss a 14-day demo, and let us show you how it works.
