What Is Customer Data Integration?

Capabilities of Customer Data Integration

Challenges of Siloed Customer Data Across Different Systems/Applications

Siloed customer data poses several challenges to businesses. When customer data is scattered across different systems and applications, it becomes challenging to consolidate and analyze it efficiently. Incomplete and fragmented customer data can lead to misguided decision-making and hinder businesses from creating personalized and targeted marketing campaigns.

Introduction to Customer Data Integration

Customer Data Integration (CDI) aims to combine customer data from various sources into a unified view. CDI interfaces with multiple databases, consolidating the information into a single, manageable repository. Having all the information in one place simplifies data management, access, and security, enabling businesses to analyze and visualize the data swiftly and efficiently.

Types of Customer Data Integrated

Various types of customer data are integrated through CDI. This includes transactional data, such as purchase details and time to purchase, and interaction data like website visits, page behavior, and app downloads. CDI consolidates data on customer profiles, purchase per click, email interactions, and push notification settings. Integrating these diverse data types gives businesses a comprehensive understanding of customer behavior and preferences, facilitating more informed decision-making and personalized customer interactions.

5 Major Benefits of Customer Data Integration

Major Benefits of Customer Data Integration

Customer data integration gives your company a 360-degree overview of your customers. It provides a detailed view of your customer’s purchase habits, locations, and other information. Sales and marketing teams benefit from this insight since it helps them concentrate their efforts on the most profitable areas. Here are some ways that customer data integration might help your company:

1. Creates New Opportunities

Integrating customer data is beneficial for identifying new opportunities. Customer needs are always changing. As a result, it is critical to integrate data constantly. Customer data analysis can give information on how customers’ wants are fulfilled. You can utilize customer data to categorize your customers by separating them into smaller groups of more closely related people. This will help you focus your marketing messages better and obtain greater results. Suppose any company wants to offer an existing product with a limited budget. In that case, the customer data integration strategy helps identify marketing leads and determine whether it is cost-effective.

2. Examines Customer Behavior

Integrating customer data allows you to investigate customer behavior in a variety of ways. It is a vital aspect of your customer data management strategy and helps to take a new look at your target audience. You can change your whole sales and marketing strategy if you know how customers think, feel, and make decisions. Analytics is the key to success because it helps buyers along their customer journey and helps keep clients coming up with new offers.

Customer data identifies popular product categories at any specific time. You can utilize this to get a competitive advantage. If you know a lot about your customers and their needs, you can predict how sales will go in the future. By looking at past and present customer information, you can stay on top of industry trends and plan ahead for what customers want.

4. Reach out to the Specific Audience

Customer data integration can help you better understand your customer’s purchasing habits and preferences. Your marketing efforts can be tailored to meet those needs. This eliminates the time-consuming process of assuming which customers to target.

5. Ensures Data Accuracy

Accurate data is critical for effective audience analysis and decision-making. Customer data integration helps you analyze customer data. You can eliminate the problematic data and collect high-quality customer data. You can make sure that your data is correct and that your decisions are based on good information.

The 3 Types of Customer Data Integration

Types of Customer Data Integration

1. Consolidation

This type of data integration is probably the most common and straightforward approach. It involves collecting data from various sources, unifying it, and storing it in a central data warehouse. This process simplifies data access for end-users and reduces the number of locations where data is stored. By consolidating data, organizations can more easily analyze and derive insights from their data.


Data propagation involves automatically copying and pasting data from one location to another. While the original data remains in its source location, a copy is created at the destination. This approach is often used when multiple tools need to share the same data. For instance, marketing automation platforms and CRMs may use data propagation to ensure both systems access the same information. Propagation is ideal for integrating a small number of data sources and is less about consolidating data than it is about synchronizing data between different tools.


Federation is a form of data virtualization that enables data from multiple sources to be accessed from a central point without consolidating the data. While it may appear similar to data consolidation from the end-user's perspective, federation keeps data separate until a user requests a specific dataset.

This approach is commonly used in situations where data consolidation would be prohibitively expensive, such as in the case of enterprises managing vast datasets. By implementing data federation, organizations can provide users with access to data across different sources without the need to physically combine the data into a single repository.

3 Common Customer Data Integration Methods

Common Methods of Customer Data Integration

1. Manual data integration

Manual data integration involves hand-coding integration built manually by an IT team. It is time-consuming, expensive, and prone to errors. Changes in data collection strategies may require the integration to be rebuilt. This method is only suitable when no other options are available.

2. Automated data integration

The tools themselves typically offer automated data integration. Companies that announce integrations with other tools are examples of automated integrations. These integrations are quick to set up, often requiring just a single click, but they are limited by the number of tools with which they can be integrated.

3. Customer Data Platforms (CDPs)

Customer Data Platforms take integration a step further by allowing connections between tools that do not natively work together. CDPs automate integrations that would otherwise require manual effort. They provide a centralized way to control all data sources, ensuring data cleanliness.
