2. Evaluate Existing Data Infrastructure

Evaluating your existing data infrastructure and processes includes assessing the quality and cleanliness of the available data to uncover inconsistencies, redundancies, or inaccuracies, helping you avoid problems down the line. Asking the following questions can assist you in thoroughly reviewing your existing data structure:

  • What are your organization’s existing data sources?
  • How are these data sources currently managed and maintained?
  • What types and volumes of data —structured, unstructured, and semi-structured, for example—are stored in each data source?
  • How often is your enterprise data updated or refreshed?
  • What are the data retention policies for each data source?
  • Are there any data governance processes or frameworks in place?
  • Are there any security concerns or vulnerabilities in the existing data infrastructure?

3. Identify Stakeholders

Key stakeholders involved in the data integration strategy from across the organization should have clear roles and responsibilities and know how they will contribute to the strategy development process. Each group plays a key role in the process and ensures that integrated data meets your business requirements. Generally, stakeholders and roles include the following:

  • Business leaders and executives—Provide strategic direction, define business goals, allocate resources, and check alignment with organizational priorities.
  • IT professionals—Implement and manage technical aspects, design and develop integration processes, select tools and technologies, and check data integrity and security.
  • Data governance teams—Establish and enforce policies, standards, and processes related to data quality, security, and compliance.
  • Business and data analysts—Identify data requirements and priorities, define business rules and metrics, and make sure that the integration strategy meets the needs of various functional areas.
  • End-users—Provide feedback on usability and functionality of the integrated data systems or applications used for data integration.

4. Define Scope And Purpose

Clearly outline the scope, purpose, and anticipated outcomes of the data integration initiative. Specify the types of data to be integrated, including customer data, sales data, and operational data. Define the geographic, organizational, and functional boundaries of the integration effort. 

Your outcomes should be measurable, concrete, and aligned with organizational goals. The following questions should be addressed during this phase:

  • What exactly are types of data to be managed?  
  • Are there any geographic, organizational, or functional boundaries that need to be considered? 
  • Are there any data sources or systems that should be excluded, and if so, why?

5. Establish Governance Framework

Governance frameworks manage data security, privacy, compliance, and overall quality throughout the integration process. Establishing them entails defining policies, standards, and processes for controlling data access for privacy and protection. 

In this step, you must clarify how the data governance responsibilities will be assigned and enforced within the organization. You should also be clear on the following:

  • The types of enterprise data you will retain
  • The retention periods for each data type
  • Data archiving or deletion processes when the retention period ends
  • Data retention regulatory requirements

6. Select Integration Technologies

Choose appropriate data integration tools and technologies based on such factors as costs, scalability, security, and your customization requirements. Keep vendor support, cost-effectiveness, and ease of integration with existing systems in mind

When selecting data integration technologies, consider the volume, variety, and velocity of enterprise data to be handled, along with the primary use cases or business processes that require integration. It is important to choose technologies that match the technical capabilities of your business and are compatible with your current systems.

Exploring different integration solutions, comparing features, capabilities, and pricing models, while considering future business growth and innovation goals are also major factors in making informed decisions in this stage.

7. Design Integration Architecture

Craft a structured plan for data flow between your corporate systems. This includes defining data models, schemas, and integration patterns. It also entails incorporating data cleansing and standardization processes for consistency and quality across integrated systems. 

By addressing errors in the data through cleansing and establishing rules for standardizing formats and values, you can raise enterprise data quality and reliability. The goal is to build a robust framework that supports seamless data integration while meeting business objectives.

8. Plan Implementation

Provide clear details about your strategy’s implementation to ensure it is both practical and executable. Create a comprehensive roadmap to put it into action that breaks it down into smaller tasks such as data mapping, system configuration, and the actual data integration process including extract, transform, and load (ETL) development. 

Additionally, tasks such as testing and deployment should be outlined. Include benchmarks or milestones, like completing data cleansing or achieving system integration, and task deadlines for the execution to remain on schedule. 

Specify the resources necessary for a successful execution, like budget provisions for technology investments, personnel, training, and any required external services or consultants. Make sure everyone knows what they’re supposed to be doing and how they fit into the big picture. Obtain the necessary tools, software, and infrastructure to support data integration activities. 

9. Test And Validate

You should meticulously evaluate the performance of your data integration processes. Define criteria and metrics to assess the quality, accuracy, and reliability of combined data. 

Conduct data validation, functionality testing, and performance testing to check if the integrated data meets predetermined standards and objectives established during the initial stages of developing the strategy. These tests must simulate real-world scenarios to accurately reflect the actual conditions and environments in which the integrated data systems will operate.

10. Monitor And Iterate

The final step of creating a data integration strategy involves establishing monitoring mechanisms to track integration performance and gauge its ongoing impact. This necessitates deploying processes to gather feedback, find issues, and make continuous enhancements to the strategy in response to evolving business needs.

Monitor key performance indicators (KPIs) related to data quality, system performance, and business outcomes. Carry out regular reviews and assessments to unearth any issues or areas for improvement, so you can make timely adjustments and refinements to your strategy. 

Frequently Asked Questions (FAQs)

What are Common Data Integration Methods?

There are a wide range of data integration methods available depending on the specific requirements and characteristics of your data sources involved. 

Manual Data Integration

This method involves manually moving data around using basic tools like spreadsheets or simple copy-paste methods. While it’s straightforward, it can be time-consuming and prone to errors. This method is often used for small-scale data integration tasks or ad-hoc data transfers between systems.

Change Data Capture (CDC)

This method tracks real-time changes in data using specialized CDC tools, so you always know what’s happening across varying systems or databases without having to constantly check. This is common in environments where real-time data replication and synchronization are imperative, such as in financial services for tracking stock market changes.

Extract, Load, Transform (ELT)

ELT encompasses extracting data from source systems and loading it into a target system without significant transformation. Transformation tasks are then performed within the target system, often using SQL queries or data processing frameworks. ELT is typically employed in data warehousing and analytics environments where large volumes of raw data need to be loaded quickly into storage systems.

Application Programming Interface (API) Integration

API integration entails connecting to external systems or services to exchange data in a structured and controlled manner. It’s used for integrating cloud-based applications, web services, and third-party platforms with internal systems.

Extract, Transform, Load (ETL)

ETL is a traditional data integration approach that involves extracting data from multiple sources, transforming it to meet the desired format or structure, and loading it into a target system such as a data warehouse or database. ETL is widely used in enterprise data integration; specifically data warehousing, BI, and data migration projects.
