15 Best Data Integration Tools [Based on Client Reviews]

Data has become a huge part of marketing in the last few years, especially as more people continue to jump on the trend of online shopping. According to Statista, the number of digital buyers will hit 2.14 billion in 2021. This means that one in every four people in the world will be shopping online.

The global number of digital buyers

This massive number represents an even more enormous level of online activity, leading to an unprecedented flow of data. High-performing marketers are always on the lookout for ways to take advantage of the huge piles of data at their disposal in a bid to understand their customers and ultimately provide solutions that will yield maximum profits in the long run.

That said, marketers are exposed to enormous floods of data from dozens of data sources every day. This can be overwhelming, hard to manage, and sometimes even useless, especially for scaling businesses. This explains why leading marketers are 72% more likely to invest in tools that can help with data quality and volume improvement.

This is where data integration tools come in handy.

In today's guide, we will look at what data integration is, why it is crucial for your business, different types of data integration tools, and much more.

Let’s jump right into it.

Data Integration in a Nutshell

Data integration is the process of pulling data from multiple sources into one location to provide a single, consolidated, and digestible view of the generated data.

Data integration is often at the core of other data-related processes like data analysis, forecasting, and reporting. The process of integrating data from multiple data sources into one consolidated location usually involves the following steps:

  • Extracting the required data from the various sources
  • Transforming the said data into compatible formats
  • Cleaning the data to get rid of errors and redundancies
  • Loading the data streams into their final destination (usually a data warehouse)

The ability to draw data from multiple sources and consolidate them into one location is instrumental to successful data-driven marketing decisions.

This is because marketers have a hard time dealing with traditional data silos that make data barely accessible to those that need it. By consolidating data streams into one location, data is not only more accessible, but marketers can make analyses and develop actionable, data-driven plans faster.

Here’s a simple example of how data integration solves the problem associated with data silos:

Let’s say you own a software company, Locksmith Inc. Your flagship software, Locksmith, is a software tool that allows users to unlock, lock and track devices remotely.

This software requires data to function and gets the required data through various means, including but not limited to the following:

  • Facebook Ads, Google Ads, LinkedIn Ads, etc. to acquire new users
  • MySQL Database service to store user data
  • MailChimp for email marketing and lead nurturing
  • Zoho for customer support
  • Square space for web hosting
  • Twillio for SMS and more

Each of these services generates a silo of data for specific aspects of Locksmith's operations. As the business grows, the silo grows as well, and it gets harder to separately work with the influx of data generated every day. To get a full view of how the business is performing in the most efficient way, you would need to consolidate the data into one location for better accessibility.

Purpose of Data Integration Tools

A survey by Impact revealed that data-driven businesses are 23 times more likely to grow their customer base, six times more likely to maintain them, and 19 times more likely to get profitable.

But what roles do data integration tools play in this scenario? This section will take a look at a few.

Let's dive into it.

Time-Efficient Data Operations

Working with data from multiple sources can be time-consuming. This is because users would need to launch the individual apps or services to get access to the data they require.

Let's say, for example, your team needs a specific set of information to generate marketing reports. The data required for this report is spread across multiple sources. You would need to spend ample time surfing through these data sources individually to get the data you need.

This is entirely doable, but things can get a little uncomfortable when you're faced with an urgent need. 

Data integration tools are designed to automatically pull all the data you need from these discrete data sources into a single destination (at super-fast rates), so you essentially need to work directly with just one data source for all your data operations.

Analysis-Ready Data

As already established in the intro, data integration involves data extraction, transformation, cleansing, and loading.

The end product of this process is usually a well-rounded and detailed set of data that marketing analysts can leverage for faster data assessment.

For example, data silos are usually designed just for the collection of raw, unrefined data from everyday activities. In reality, not all data contained in these silos will be accurate and valuable, but sieving through this pool of data is tricky. 

However, data ingestion tools have the capability of doing this in record time, allowing marketers to get granular, analysis-ready data right off the bat.

Enhanced Visibility Across the Company

Medium and large-scale enterprises comprise several teams encompassing marketing, sales, product development, and customer service, among others.

These teams generate data from their different day-to-day activities. This gives rise to data silos in each of these departments. With data silos, it is hard to achieve cross-visibility among the departments in the company. Sharing data is difficult, consequently making it hard for teams to collaborate.

For example, data from the marketing team may not be readily available to the product development team when they need it. This can slow down decision-making processes and hamper productivity.

Data integration tools make data accessible to anyone at any time, making it easier to share data and collaborate.

Marketing Data Alignment

Sometimes, when you generate marketing data from different sources, you would find that some data sets have striking similarities based on the nature of the activities used to generate them. Integrating these data sets will help you make better analyses and optimize your marketing efforts by leveraging the overlap.

However, to achieve this, you would need to ensure that the variables found in the data sets, and the values of the variables, can be matched.

This process is a breeze-through for data integration tools. By aligning marketing data, data integration tools save a ton of time and make the job easier for marketers.

Sales Funnel Optimization

Sales funnel optimization involves finding specific stages of your sales funnel that have promising levels of customer engagement and improving them to yield even better results. It also involves getting rid of roadblocks or elements in the sales funnel that have no positive impact on a customer's journey throughout a sales funnel.

This information can only be obtained by analyzing the pool of data generated from the customer’s activities within the sales funnel.

As you would have already guessed, having all your customer-related data in one place makes it easier to optimize their experience and convert them into loyal, repeat customers.

Effective Omnichannel Marketing

Omnichannel marketing refers to the process of nurturing your potential customers and improving their experience across all your marketing channels.

For instance, if you’re marketing to a customer through email, social media, blog, and app, you would need to ensure that their experience remains positive no matter what platform they’re on.

To monitor their experience and make improvements, you would need to pull data from all these platforms. And to do this effectively, data integration tools are your best bet.

Data Profiling and Cleansing

Data profiling is the process of identifying errors, missing information, and redundancies in a data set. On the other hand, data cleansing is the process of fixing anomalies found in a data set.

Business activities generate large piles of data from their daily activities, and some of the data generated from these activities can sometimes be riddled with errors.

Manually profiling and cleaning these data sets can be a daunting task. But data integration makes it relatively more straightforward.

Types of Data Integration Tools

Data integration tools are grouped into four basic types based on criteria such as where they’re hosted and the costs associated with them.

Let’s take a look at them below.

In-house Data Integration Tools

These tools, also known as on-premise data integration tools, are designed to work with data from in-house data sources. They’re typically sold as standalone products and installed in the company’s local IT infrastructure or hosted in a private cloud environment.

In-house integration tools make use of native connectors for batch loading of data from various local sources.

In-house data integration tools are usually complex and relatively more time-consuming to set up as vendors would usually update connectors every time there’s a new program or data source. You also have to consider the high costs associated with this category of integration tools.

Some popular in-house data integration tools include:

  • Microsoft SQL
  • Cleo
  • Peregrine Connect
  • Omatic Software
  • Skyvia
  • AWS Server Migration Service
  • AWS Snowball Edge
  • Olik Replicate
  • Informatica PowerCenter

Cloud-Based Data Integration Tools

Unlike in-house data integration tools, cloud-based tools are hosted on the cloud. This can either be developed by the company or purchased from a service provider.

Cloud-based data integration tools are mostly Integrated Platforms as a Service (iPaaS) designed to pull data from various in-house and cloud-based data sources into a remote data warehouse.

Versus in-house data integration tools, cloud-based tools are more cost-efficient as businesses don’t have to build custom infrastructures entirely from scratch. Since they’re web-based, they come with more advanced, out-of-the-box features and can be updated and integrated rapidly. Cloud-based tools, such as a cloud landing zone, are often considered more cost-efficient. Additionally, it's crucial for businesses to conduct a thorough analysis based on their specific needs, usage patterns, and long-term goals.

Some popular cloud-based tools include:

  • Improvado
  • Boomi Atomsphere
  • Jitterbit
  • Talend Cloud Integration
  • Informatica
  • SnapLogic

Open-Source Data Integration Tools

Open-source integration tools are free-to-use and supported by a community of developers and experts. It is important to understand that while these are basically free on the surface, there are possible hidden charges you might incur (network throughput, servers, training, etc.) 

Also, there is no dedicated technical support team for these tools. You only have the community and the tool’s documentation. You might also be required to take charge of data security and privacy compliance.

Some popular open-source tools include:

  • Karma
  • Myddleware
  • CloverETL
  • Pentaho Data Integration (Kettle)
  • Pimcore
  • Talend Open Studio

Points to Consider While Choosing Data Integration Tools

While trying to choose a data integration tool, the sheer number of options can be overwhelming. But to help you narrow these down to the best, we’ve included some of the factors you can consider while choosing your go-to data integration tool.

Let’s take a look.

Number of Supported Data Sources

Your data integration strategy will change as your business continues to grow. As your business grows, there will also be an increase in the number of data sources used. That said, you need to ensure that the data integration tool can support an expanding list of data sources.

Data Update Frequency

Do you need your data to be processed in real-time or in batches? This really depends on how your business is structured. But if you're a modern business using modern tools, you'd probably prefer real-time data integration.

Not every data integration tool has this functionality. So, be sure to look out for the ones that do.

Data Transformation

While using different data sources, you’d find that these sources generate data in different formats. For example, data source A might have the date format MM-DD-YY while data source B might have an entirely different format. To make data-driven decisions, businesses need to get these data sets into a common format for easy analysis. 

This is where data transformation comes into play. You need to choose a platform that has proven to offer seamless data transformation.

Data Mapping

The process of mapping data is an essential part of an organization’s data flow. It encompasses all the processes involved in homogenizing multiple data sets into a single group. 

You need to ensure that the data integration tool you’re considering has the capability of mapping different data sets with related fields and combining them in a way that makes them accurate and usable at the end destination. Data harmonization is a vital but also very time-consuming process for marketing analytics. That’s why automation of routine operations like data mapping can significantly accelerate marketing performance.

For example, Improvado’s MCDM algorithm automates the process of data mapping and saves analysts time when integrating new data sources. 

Amount of Engineering Skills Required

Usability is another factor you ought to consider. What’s the learning curve associated with the data integration tool?

Obviously, the easier it is to learn and use, the better.


As your business grows, the amount of data you work with will grow as well. This also means that you will be working with more data sources, and your data infrastructure will generally get more robust.

You should consider using a data integration tool that can scale with your business.

Security and Compliance

If your business works with critical data, you need to ensure that the data integration tool you're considering offers solid expertise, resources, and protocols that handle security and compliance.

Size of Your Business

While there are several data integration tools available, they’re all designed to suit different businesses at different levels.

Some are better for smaller businesses, while some are more suitable for large enterprises. As we go into the next section, we will categorize our list of data integration tools based on the business size they’re best suited for.

User Reviews

This is one of the most important things to consider while choosing your data integration tool. User reviews from trusted platforms will give you an insight into how these tools are helping businesses with their data integration strategy requirements.

You may want to pay more attention to tools that have higher ratings per review ratios. For example, a tool with 4.8 stars from 5000 reviews is probably better than another tool with 4.8 stars from 50 reviews.

This effectively leads us into the next (and main) section of this guide.

Top 15 Data Integration Tools

Data integration tools are basically responsible for helping businesses move data from multiple sources into one destination. During this process, these tools will handle other functions such as mapping, transformation, and cleaning, to ensure that the data delivered will have the best quality possible.

Upgrade Your Business with the Right Integration Tool

Having gone through our list of data integration tools, along with the criteria for choosing the best fit for your business, we hope that you’ve made up your mind at this point.

However, if you need more guidance, we’re happy to help you discover how your business can benefit from the right data integration tool. Contact an expert here.


How is Data Integration Used?

Data integration is used for different purposes such as business intelligence, customer-company relationship, data virtualization, and more.

What is Data Integration?

Data integration is the process of pulling data from multiple sources into one location to provide a single, consolidated, and digestible view of the generated data.

Data sources can include marketing platforms, servers, CSV files, or anything at all, as long as it is a system that can generate data for your business.

What is an Example of Data Integration?

Both large and small businesses use data integration to make better data-driven decisions. Here’s an example of data integration in action:

Let’s say you own a company called Locksmith Inc. Locksmith has a large customer base from months of intensive marketing across several channels. To get a well-rounded view of each customer, you would need to pull the data from all these sources into a single data warehouse.

Analyzing these data separately from each source can be time-consuming and prone to errors. However, consolidating these data will make them easier to access for analysis purposes. 

What are Data Integration Techniques?

There are five major data integration techniques, namely:

Manual Data Integration: This involves manually connecting all data sources to the destination, collecting the data, cleaning it, transforming it, and more without automation. This usually involves writing custom codes for different sources. 

Middleware Data Integration: This involves using middleware tools to facilitate the transfer of data from source systems to a single destination. This is usually useful when you want to foster communication between legacy systems and new ones to speed up data integration.

Application-Based Integration: This involves the use of software applications to locate, retrieve, and transform data before integrating it into the chosen destination.

This technique usually involves automation, low code, and prebuilt data integration pipelines, among others.

Uniform Data Access Integration (UDAI): UDAI leaves data sets within their original source systems while defining a consolidated set of views to allow users across all departments to get a unified view.

Common Storage Integration: This is similar to UDAI, but the data remains in the source systems while copies of the data are loaded to a central location to provide users with a unified view.
