What Is Data Integration in Business Intelligence: Key Steps, Top Tools & Best Practices

Whether in healthcare or the retail industry, everyone needs data to succeed in their business. Data helps make clear decisions and helps businesses understand people and their needs. That is why data integration in business intelligence is very important.

In this blog, you will explore data integration in business intelligence, its frameworks and components, its importance, steps to set up data integration, best practices, tools and technologies, challenges, and its use cases.

What Is Data Integration in Business Intelligence?

One of the main components of any data technology solution is data integration. It not only helps you to effortlessly access all of the data you need to make smart business decisions but also helps in transforming and combining data sources for reliable analysis. Understanding your data provides crucial insights that help business users to swiftly evaluate what actions should be performed. Furthermore, these insights can lead to new ideas for companies, even more effective operations, prospects for growth, and more.

Framework & Components of Data Integration in BI

In business intelligence (BI), data integration brings data from different sources into a central system. It has five key components: data sources, extraction, transformation, loading, and storage.

1. Firstly, data is stored by businesses in various places, such as databases, cloud apps, spreadsheets, or APIs.
2. Secondly, it is extracted from these sources, often with the help of automated tools or scripts.
3. The data must be cleaned and formatted to fix errors and improve consistency.
4. It is then loaded into a central storage system like a data warehouse.
5. Lastly, they store it in a central location to simplify reporting and querying.

Why Is Data Integration Important for Business Intelligence? 

As data is essential for every industry, data integration is vital for business intelligence. Following are some of the key benefits of data integration in business intelligence:

1. Collaboration Between Departments

Data integration allows for real-time data access and exchange across departments. This makes data silos easier to break down and allows for cross-functional analysis.

2. Time Management

Preparing datasets for analytics and processing takes time. It typically includes data cleansing, conversion, and imports, and the more sources included, the longer the time required. Data integration automates data exports and enables customization, allowing for speedier data preparation and analysis.

3. Minimisation of Error and Rework

Manual data collection frequently produces incomplete, inconsistent, incorrect, and inaccurate data sets. This is especially true when they are executed from many locations and accounts.

Corrupted data usually leads to incorrect reports, misleading analyses, and overall errors in judgment. Data integration solutions synchronize data to eliminate reporting rework and ensure that it is accurate and up to date.

4. More Valuable Data

Data centralization and standardization boost the long-term value of company data. They also help identify potential issues and enforce improvements in data accuracy and quality analysis.

Traditional data integration approaches, such as extract, transform, and load (ETL) methods, sometimes fail to handle large amounts of data. That is why a new business intelligence data integration approach is needed.

Some of the new approaches include:

1. Cloud-based integration for storing and computing data.
2. Use of machine learning (ML) for data cleaning and processing.
3. Use of data visualization.
4. Use of APIs and Microservices.

How to Set Up Data Integration in Business Intelligence? 

Here are 10 steps by which you can setup data integration in business intelligence:

• Step 1: Define your objectives and requirements by identifying business goals, determining data needs, and setting integration goals.  
• Step 2: Choose the right data integration tools by evaluating options such as ETL tools (e.g., Hevo Data, Informatica, Talend) and cloud-based solutions (e.g., AWS Glue).
• Step 3: Ensure the tools are compatible with your existing systems and BI platforms (e.g., Power BI, Tableau).  
• Step 4: Map out your data sources, including databases, APIs, spreadsheets, and cloud applications.  
• Step 5: Design a data integration workflow, including extraction, transformation, and loading processes.  
• Step 6: Clean and standardize data to ensure consistency, accuracy, and quality.  
• Step 7: Set up a data warehouse or data lake to store integrated data for analysis.  
• Step 8: Implement data transformation rules to align data formats, remove duplicates, and handle missing values.  
• Step 9: Test the integration process to ensure data flows correctly and meets business requirements.  
• Step 10: Monitor and maintain the integration system to address errors, optimize performance, and adapt to new data sources.  

Best Practices for Data Integration in BI 

• Before integrating data from different sources, make sure it’s accurate, complete, and formatted properly. Cleaning up duplicates, fixing inconsistencies, and filling in missing values will save you headaches later.
• A good Extract, Transform, Load (ETL) process is essential for moving data smoothly. It should be efficient, scalable, and able to handle large amounts of data without slowing things down or losing accuracy.
• Whether it’s a data warehouse or a data lake, having one main place for all your integrated data ensures consistency and makes it easier to analyze and report on.
• If your business needs up-to-date insights, real-time or near-real-time data integration is the way to go. Using modern tools like streaming ETL and APIs can help ensure you’re working with the freshest data.
• Data security and governance should never be an afterthought. Setting clear rules on who can access what, ensuring compliance with regulations, and protecting sensitive data will keep your BI system secure and reliable.

What to Consider Before Choosing the Data Integration Tool for Business Intelligence 

Before choosing the right tool, you should consider a few things:

1. Make sure the tool can connect to all the systems where your data lives, whether stored in databases, cloud storage, or third-party apps. It should handle both structured and unstructured data easily.
2. As your data grows, your tool should be able to keep up. Look for something that can handle increasing volumes of data without slowing down and supports both real-time and batch processing.
3. A tool that is easy to navigate and automates tasks (such as scheduled ETL processes) will save you time and reduce manual effort, making the whole process smoother for your team.
4. Your data is valuable and sometimes sensitive, so make sure the tool has strong security features like encryption, compliance, and access controls.

Common Challenges in Data Integration for BI 

Even though there are a lot of benefits, there are still various challenges that arise while integrating data in business intelligence:

1. Huge Amounts of Data

The growing volume of valuable data makes data integration much more difficult. Business analytics tools can handle large datasets, and data storage is reasonably priced. The true difficulty, though, lies in controlling data integration and quality. This is particularly true when handling large volumes. Implementing simplified approaches, large-scale aggregation and sorting activities, and joining massive datasets impede normal integration tasks and logistics.

2. Various Data Sources

Standard structured datasets, streaming data, social media content, and ecosystem data from several stakeholders are some of the common examples of data sources. This diversity makes data integration much more difficult.

Conventional data warehouses, which are based on relational databases, can manage some diversity. However, they lack the resources necessary for unstructured data processing or data stream integration. Well-designed data lakes may handle different sorts of data. However, they may not always be as reliable or accessible as an SQL database.

3. Concerns Regarding Data Quality

Out-of-date, inaccurate, and incomplete data presents significant problems. In fact, maintaining consistency is always hampered by large quantities and a variety of sources. As a result, decisions may be made using tainted or redundant data.

4. Data Security and Privacy Challenges

Data security and privacy involve thoroughly examining regulatory compliance, access limits, and encryption. Data transfers may result in unauthorized access and breaches, which can cause significant commercial losses. As a result, data masking techniques, unambiguous data ownership frameworks, and compliance with data protection standards are essential.

Use Cases of Data Integration in Business Intelligence 

Different industries are using data integration to meet their specific needs. Here are some use cases:

• In e-commerce, businesses integrate supplier, inventory, and customer data to better manage inventory, speed up fulfillment, and improve shopping experiences. 
• In marketing, data from research, CRM systems, and social media are used to customize campaigns and measure their success.
