What is Data Integration?

Data integration is the process of combining data from multiple sources into a unified view, enabling organizations to access and analyze data from various origins seamlessly. This process involves the ingestion of data and typically uses the ETL (Extract, Transform, Load) approach. ETL extracts data from different sources, transforms it into a consistent format, and loads it into a unified system. By consolidating structured, unstructured, batch, and streaming data, data integration ensures that organizations have a comprehensive and accurate dataset for analysis and decision-making.

Common Challenges in Data Integration and How to Overcome Them

Data integration can be challenging, especially when dealing with disparate data sources, manual data entry, and data silos. However, there are several ways to overcome these challenges:

  1. Data Transformation – One of the biggest challenges in data integration is transforming disparate data into a unified format. As data flows from multiple sources, differences in structure, format, or standards create compatibility issues. Using middleware data integration tools can automate these transformations, improving consistency and reducing manual errors.
  2. Incompatible APIs – Systems often rely on incompatible APIs, which complicates data sharing and integration. A virtual database or data federation can help by connecting data across systems, allowing different platforms to communicate seamlessly.
  3. Growing Data Volumes – With the rise of IoT and big data, handling large data volumes can strain data processing resources. Implementing scalable data integration solutions and data warehouses allows businesses to store data efficiently, ensuring critical data is accessible for analysis.
  4. Data from New Sources (e.g., IoT) – Integrating data from newer sources, like IoT devices, introduces data quality and connectivity issues. Developing a robust data integration strategy that accounts for real-time data propagation is key for maintaining accuracy and timeliness.
  5. Data Quality Issues – Integrating data from different systems often exposes data quality issues, such as inconsistencies or duplicates. Establishing a unified platform with data quality checks helps maintain accurate data, which is essential for reliable business intelligence and decision-making.
  6. Complexity in Large Organizations – For large organizations, consolidating data from different departments and systems can be daunting. Assigning a dedicated data team to manage integration efforts and create a comprehensive integration strategy is crucial to streamlining data consolidation and enhancing operational efficiency.

Effectively addressing these data integration challenges allows businesses to seamlessly consolidate data, which can provide a more complete picture of operations and enable accurate, data-driven decisions.

Real-World Applications of Data Integration Across Industries

Data integration has numerous real-world applications, including enhancing operations and customer experiences in the following industries:

  • Healthcare: Hospitals and healthcare providers integrate patient data from multiple data sources, including electronic health records (EHRs) and lab results, into a unified system. This consolidated data enables physicians and medical staff to access complete patient histories, leading to more accurate diagnoses, efficient care delivery, and improved patient outcomes.
  • Retail: Retailers use data integration tools to centralize sales, inventory, and customer data from multiple channels. By integrating business data, retailers can maintain accurate inventory levels, optimize product availability, and track customer purchasing patterns, ultimately enhancing the overall shopping experience.
  • Financial Services: Financial institutions rely on data integration strategies to identify potential fraud and uncover cross-selling opportunities. By combining data from disparate sources, these organizations can analyze customer data in real-time to detect suspicious transactions and provide personalized financial products, increasing customer loyalty.
  • Telecommunications: Telecom companies integrate customer data across various services to build a comprehensive view of customer interactions. This approach allows data analysts and customer service teams to identify usage trends, respond to service issues more effectively, and offer personalized service enhancements.
  • E-commerce: E-commerce platforms leverage data integration to monitor customer experiences and sales metrics across multiple online platforms. Integrated data provides valuable insights into customer behavior and sales trends, enabling companies to optimize marketing campaigns and improve customer satisfaction.

By implementing robust data integration solutions, organizations across these industries can enhance their operations, reduce costs, and deliver superior customer experiences.

Why Data Integration is Important for Business Operations

Data integration plays a critical role in enhancing organizational performance by consolidating information from disparate sources, such as transactions, social media, and customer interactions. The benefits of data integration include enhancing operational efficiency, improving data accuracy, and fostering innovation, which are essential for businesses to thrive in a data-driven environment. This integration provides businesses with accurate, up-to-date data essential for informed decision-making. Moreover, integrated data enables a comprehensive view of business operations, breaking down data silos that often hinder collaboration and impede efficient workflows.

With data integration software and a well-planned integration strategy, companies can streamline operations, improve data access, and ensure that each department has timely, relevant data for analysis. By using data integration tools and techniques, companies eliminate redundant data handling processes, reducing the risks associated with manual data entry errors and fragmented data. Ultimately, a robust data integration approach not only promotes operational efficiency but also offers a competitive edge by delivering actionable insights that support strategic initiatives.

Provide IT Portfolio Management with Data Integration

Over the years, I have had the opportunity to perform dozens of data warehousing and analytics assessments. During these assessments, I always ask the client how much they spend annually on data warehousing / business intelligence / analytics.  The majority of companies and government organizations cannot give a relatively good estimate on what they actually spend.  In order to manage these and any other costly information technology (IT) initiatives it is critical to measure each one of them.  However, it is impossible to measure them when most companies do not understand them (see Figure 1: “How to Manage IT”).  This is where IT Portfolio Management enters the picture.

Figure 1: How to Manage IT

IT portfolio management refers to the formal process for managing IT assets. And IT asset is software, hardware, middleware, IT projects, internal staff, applications and external consulting. Like every newer discipline, many companies that have started their IT portfolio management efforts have not done so correctly.  There are some keys to building successful IT portfolio management applications, including metadata management.

Properly managing their IT portfolio allows the corporation to see which projects are proceeding well and which are lagging behind. In my experience, almost every large company has a great deal of duplicate IT effort occurring (see later section on “Reduce IT Redundancy”).  This happens because the metadata is not accessible. At EWSolutions we have some large clients whose primary goal is to remove these tremendous redundancies, which translates into enormous initial and ongoing IT cost savings.

Reduce IT Redundancy

CIO is commonly defined as Chief Information Officer; however, there is another possible meaning to this acronym: “Career Is Over”. One of the chief reasons for this nickname is that most IT departments are “handcuffed” in needless IT redundancy that too few CIOs are willing and capable of fixing.

There are several CIO surveys that are conducted annually.  These surveys ask “what are your top concerns for the upcoming year”.  Regardless of the survey, “data integration” will be high on the list.  Data integration has two facets to it.

  • One is the integration of data and relevant metadata across disparate systems for enterprise applications.
  • The second is the integration/removal of IT redundancies.

Please understand that some IT redundancy is a good thing.  For example, when there is a power outage and one of your data centers is non-operational you need to have a backup of these systems/data.  However, when I talk about IT redundancies I am addressing “needless” IT redundancy; IT redundancy that only exists because of insufficient management of our IT systems.  I was working with a Midwestern insurance company that, over a four-year span had initiated various decision support efforts.  After this four year period they took the time to map out the flow of data from their operational systems, to their data staging areas and finally to their data mart structures.  What they discovered was Figure 2: “Typical IT Architecture.”

Integeration 12

Figure 2: Typical IT Architecture

What is enlightening about Figure 2 is that when I show this illustration during a client meeting or at a conference keynote address the typical response that I receive from the people is “Where did you get a copy of our IT architecture?”  If you work at a Global 2000 company or any large government entity, Figure 2 represents an overly simplified version of your IT architecture.  These poor architecture habits create a litany of problems including:

  • Redundant Applications/Processes/Data
  • Needless IT Rework
  • Redundant Hardware/Software

Redundant Applications/Processes/Data Silos

It has been my experience working with large government agencies and Global 2000 companies that needlessly duplicate data is running rampant throughout our industry.  In my experience the typical large organization has between 3 – 4 fold needless data redundancy.  Moreover, I can name multiple organizations that have literally hundreds of “independent” data mart applications spread all over the company.  Each one of these data marts is duplicating the extraction, transformation, and load (ETL) that is done centrally in a data warehouse.  This greatly increases the number of support staff required to maintain the data warehousing system as these tasks are the largest and most costly data warehousing activities.  Besides duplicating this process, each data mart will also copy the data as well requiring further IT resources.  It is easy to see why IT budgets are straining under the weight of all of this needless redundancy.

Needless IT Rework

During the requirements gathering portion of one of our metadata management initiatives I had an IT project manager discuss the challenges that he is facing in analyzing one of the mission-critical legacy applications that will feed the data warehousing application that his team has been tasked to build.  During our interview he stated, “This has to be the twentieth time that our organization is analyzing this system to understand the business rules around the data.”  This person’s story is an all too common one as almost all organizations reinvent the IT wheel on every project.

This situation occurs because usually separate teams will typically build each of the IT systems and since they don’t have a Managed Metadata Environment (MME), these teams do not leverage the other’s standards, processes, knowledge, and lessons learned. This results in a great deal of rework and reanalysis.

Redundant Hardware/Software

I have discussed a great deal about the redundant application and IT work that occurs in the industry.  All of this redundancy also generates a great deal of needless hardware and software redundancy.  This situation forces the enterprise to retain skilled employees to support each of these technologies.  In addition, a great deal of financial savings is lost, as standardization on these tools does not occur.  Often a software, hardware, or tool contract can be negotiated to provide considerable discounts for enterprise licenses, which can be phased into.  These economies of scale can provide tremendous cost savings to the organization.

In addition, the hardware and software that is purchased is not used in an optimal fashion.  For example, EWSolutions has a client that has each one of their individual IT projects buy their own hardware. As a result, they are infamous for having a bunch of servers running at 25% capacity.

From the software perspective the problem only gets worse. While analyzing a client of mine I had asked their IT project leaders what software vendors have you standardized on? They answered “all of them!”  This leads to the old joke “What is the most popular form of software on the market?  Answer…Shelfware!”  Shelfware is software that a company purchases and winds up never using and it just sits on the shelf collecting dust.

Prevent IT Applications Failure

When a corporation looks to undertake a major IT initiative, like a customer relationship management (CRM), enterprise resource planning (ERP), data warehouse, or e-commerce solution their likelihood of project failure is between 65% – 80%, depending on the study referenced. This is especially alarming when we consider that these same initiatives traditionally have executive management support and cost many millions of dollars. For example, I have one large client that is looking to roll out a CRM system and an ERP system globally in the next four years. Their initial project budget is over $125 million!  In my opinion, they have a 0% probability of delivering all of these systems on time and on-budget.  Consider this, when was that last time that you’ve seen an ERP or CRM initiative being delivered on time or on budget?

When we examine the causes for these projects failure several themes become apparent.  First, these projects did not address a definable and measurable business need.  This is the number one reason for project failure, data warehouse, CRM, MME, or otherwise.  As IT professionals we must always be looking to solve business problems or capture business opportunities.  Second, the projects that fail have a very difficult time understanding their company’s existing IT environment and business rules.  This includes custom applications, vendor applications, data elements, entities, data flows, data heritage and data lineage.

MME’s Focus on Data Integration

Many of these Global 2000 companies and large government organizations are targeting MME technology to assist them in identifying and removing existing application and data redundancy.  Moreover, many companies are actively using their MME to identify redundant applications through analysis of the data.  These same companies are starting IT application integration projects to merge these overlapping systems and to ensure that future IT applications do not create needless redundancy.

Conclusion

If your organization can reduce its applications, processes, data, software, and hardware, lower the likelihood of IT project failure ,and speeds up the IT development life-cycle, then clearly it will greatly reduce a company’s IT expenditures.  For example, a large banking client requested an analysis of their IT environment.  During this analysis, we discovered that they have a tremendous amount of application and data redundancy.  Moreover, I figured out that they have over 700 unique applications.

I then compared this client to a bank that is more than twice its size; however, this larger bank has a world-class MME and uses it to manage their systems properly.  As a result, they have fewer than 250 unique applications.  Clearly, a bank with more than 700 applications has a great deal of needless redundancy as compared to a bank that is more than twice its size and has less than 250 applications.  Interestingly enough, the bank that has fewer than 250 applications and has a world-class MME is also 14 times more profitable than the bank maintaining over 700 applications.  It doesn’t seem like a very far stretch to see that the less profitable bank would become much more profitable if they removed this redundancy.
