There are a number of best practices that can be followed when integrating data to boost the ROI and efficiency of a business. These practices can help to ensure that all data is collected, processed, and analyzed in a timely and accurate manner. This will ultimately improve the overall performance of the business.

What Is Data Integration and Why Is It Needed?

Data integration entails aggregating data from multiple disparate sources into a single, unified view. It is needed in order to enable organizations to make better use of their data and to make business decisions. Data integration is necessary because data is often stored in different formats, in different locations, and in different source systems. By integrating data from multiple sources, organizations can gain a more complete and accurate view of their operations, customers, and markets, which can help them to identify new opportunities, improve efficiency, and make better decisions.

Data integration is used for different purposes, for example, data warehousing is one of the most common use cases where data integration is needed. Data warehousing allows organizations to store large amounts of data from various sources in a central repository and make it accessible for reporting and analysis. Other use cases include Master Data Management (MDM), where data integration is used to ensure that a business’s core data is accurate and consistent across all systems. Additionally, organizations may use data integration to create a data lake, which is a centralized repository that allows raw data to be stored in its original format and enables various business users to access the data for different purposes such as Machine Learning and Business intelligence.

1. Build The Right Data Integration Strategy

It is important to have a clear data integration strategy before beginning any projects. This will help to ensure that all data is collected, processed, and analyzed in a consistent and effective manner. Additionally, a data integration strategy can help to optimize processes and increase efficiency. Below are some of the examples you can use: 

Extract, Transform, Load (ETL)

This strategy involves extracting data from multiple sources, transforming it to fit a common format, and loading it into a destination system.

Enterprise Information Integration (EII)

This strategy involves creating a virtual view of disparate data sources, allowing users to access and query the data as if it were all stored in a single location.

Data Virtualization

This strategy involves using a middleware layer to access and combine data from multiple sources in real-time, without the need for physical integration.

Master Data Management (MDM)

This strategy involves maintaining a consistent and accurate view of key data entities, such as customers, products, and suppliers, across multiple systems.

Data warehousing

This strategy involves storing data from multiple sources in a central location, typically a data warehouse, and using tools such as SQL to query and analyze the data.

2. Use APIs For Data Integration

API (Application Programming Interface) technology can be used to integrate data from various sources. This makes it easier for businesses to collect and process data from numerous sources in a timely manner. Additionally, APIs allow for the automation of certain processes. This will help to improve the overall efficiency of the business.

API’s are particularly helpful when it comes to access data from external sources. 

3. Integrate With Automated Data Processing Systems

Businesses should also integrate with automated data processing systems to improve the accuracy and timeliness of data analysis.

An Automated Data Processing (ADP) system is an automated system that is used to collect, store, process, and analyze data in order to support various business operations and decision-making processes. ADP systems can include a wide range of technologies, such as computer hardware, software, databases, and networking systems, and can be used for tasks such as financial management, inventory control, and customer relationship management. These systems are designed to automate repetitive or manual tasks, increase efficiency and accuracy, and provide real-time data access and analysis.

These systems can help to automate complex processes and reduce the time required to collect and process data. Additionally, they can provide detailed reports that help managers make informed decisions about their business operations.

Some examples of automated data processing systems include:

Enterprise resource planning (ERP) systems

These are integrated software systems that are used to manage various business processes such as accounting, inventory management, human resources, and customer relationship management. Examples of ERP systems include SAP, Oracle, and Microsoft Dynamics.

Customer relationship management (CRM) systems

These systems are used to manage interactions with customers, including sales, marketing, and customer service. Examples of CRM systems include Salesforce, Zoho CRM, and Pipedrive.

Supply chain management systems

These systems are used to manage the flow of goods and services from suppliers to customers. Examples of supply chain management systems include Oracle SCM, SAP SCM, and JDA Software.

Data warehouse systems

These systems are used to store and manage large amounts of data, and are designed to support business intelligence and data analytics applications. Examples of data warehouse systems include Amazon Redshift, Google BigQuery, and Microsoft Azure Data Warehouse.

Accounting systems

These systems are used to manage financial transactions, including accounts payable and accounts receivable, general ledger, and payroll. Examples of accounting softwares include QuickBooks, Xero, and Sage 50. Using them makes it easier to track and manage key costs, including those for staffing, so dealing with things like shift differentials becomes less of a challenge, even if your operations are becoming increasingly sprawling and complex.

There are variety of iPaaS, or integration platform as a service available, which help to integrate and move data from various sources into these systems.

4. Use The Correct Data Mining Techniques

Data mining techniques can be used to extract valuable insights from large data sets. This can help managers to make more informed decisions about their business operations and optimize processes. Additionally, data mining can identify potential Issues and risks that may not have been apparent prior to analysis.

Some popular Data Mining Techniques include: 

  • Association rule learning
  • Clustering
  • Classification
  • Anomaly detection
  • Regression analysis
  • Sequential pattern mining
  • Time series analysis
  • Text mining
  • Link analysis
  • Recommender systems
  • Factor analysis
  • Neural networks
  • Decision trees
  • Support vector machines (SVMs)
  • Random forests
  • Gradient boosting
  • Naive Bayes

5. Understand Dataflows and Implement Parallel DataFlows

A dataflow, in the context of data integration, refers to the sequence of steps or processes that are used to extract, transform, and load (ETL) data from various sources into a target system, such as a data warehouse or data lake. The dataflow is typically designed to handle the movement of large amounts of data and can include several stages, such as:

Data extraction: This step involves retrieving data from various sources, such as databases, flat files, APIs, etc.

Data transformation: This step involves cleaning, filtering, and transforming the data so that it is in a format that can be loaded into the target system. This can include tasks such as data validation, data mapping, data normalization, and data aggregation.

Data loading: This step involves moving the transformed data into the target system, such as a data warehouse or data lake. This can include tasks such as data indexing, data partitioning, and data deduplication.

Data monitoring: This step involves monitoring the dataflow to ensure that it is running smoothly and that any errors or issues are identified and addressed in a timely manner. This can include tasks such as data auditing and data quality checks.

It’s worth noting that dataflow can also refer to the movement of data within a system, and not only between different systems.

Parallel Dataflows

Parallel dataflows refer to the practice of executing multiple dataflow tasks simultaneously, in order to increase the performance and efficiency of the data integration process. This can be done by dividing the dataflow into smaller, independent tasks that can be executed in parallel on different machines or processing cores.

There are several benefits to using parallel dataflows, including:

Increased performance: By executing multiple tasks in parallel, the overall processing time is reduced, resulting in faster data integration.

Improved scalability: Parallel dataflows can be easily scaled to handle large amounts of data by adding more machines or processing cores.

Better fault tolerance: If one task in a parallel dataflow fails, the others can continue to run, reducing the impact of a failure on the overall process.

Greater flexibility: Parallel dataflows can be designed to handle different types of data and tasks, making it easier to adapt to changing requirements.

There are different ways to implement parallel dataflows, such as using parallel data processing frameworks like Apache Hadoop, Apache Spark, and Apache Flink, or using cloud-based services like Amazon EMR and Google Cloud Dataflow. It is also possible to use parallel dataflow frameworks to handle big data and distributed computing, like Apache Nifi and Apache Kafka.


Overall, data integration projects are a key component of a data-driven approach to business, which enables organizations to gain a more comprehensive understanding of their operations, customers, and markets, and to make better decisions based on that understanding.

A data engineer is a very lucrative job. According to data from Glassdoor, the average salary for a data engineer in the US is around $92,000 per year, but it can range from $70,000 to $130,000 per year.

Having the right data integration tools and the strategy are very important to drive the strategic decisions and achieve business goals. The above mentioned integration solutions can surely help data analysts and engineers on how to be better with the actual implementation.
