Informatica IDMC Match and Merge Process: A Comprehensive Guide

The Match and Merge process in Informatica Intelligent Data Management Cloud (IDMC) plays a critical role in Master Data Management (MDM) by unifying and consolidating duplicate records to create a “golden record” or a single, authoritative view of the data. This functionality is particularly important for Customer 360 applications, but it also extends to other domains like product, supplier, and financial data.

In this article, we’ll break down the core concepts, the configuration details, and the Cloud Application Integration processes involved in implementing Match and Merge within Informatica IDMC.

1. Key Concepts in Match and Merge

a. Match Process:

• Matching refers to identifying duplicate or similar records in your data set. It uses a combination of deterministic (exact match) and probabilistic (fuzzy match) algorithms to compare records based on pre-configured matching rules.

• The process involves evaluating multiple attributes (such as name, email, address) and calculating a “match score” to determine if two or more records are duplicates.

• Match Rule: A match rule is a set of criteria used to identify duplicates. These rules consist of one or more conditions that define how specific fields (attributes) are compared.

• Match Path: When matching hierarchical or relational data (like customer with their addresses), the match path defines how related records are considered for matching.

b. Merge Process:

• Merging involves consolidating the matched records into a single record. This process is guided by survivorship rules that determine which data elements to keep from the duplicate records.

• The goal is to create a golden record, which is an authoritative version of the data that represents the most accurate, complete, and up-to-date information.

c. Survivorship Rules:

• Survivorship rules govern how to prioritize values from different duplicate records when merging. They can be configured to pick values based on data quality, recency, completeness, or by source system hierarchy.

• Common strategies include: most recent value, most complete value, best source, or custom rules.

d. Consolidation Indicator:

• A flag or status in the IDMC system that indicates whether a record is a consolidated master record or if it is a duplicate that has been merged into a golden record.

2. Configuration of Match and Merge in Informatica IDMC

To configure Match and Merge in Informatica IDMC, there are several steps that involve setting up match rules, survivorship strategies, and managing workflows in the cloud interface.

a. Creating Match Rules

Match rules are at the core of the matching process and determine how potential duplicates are identified. In IDMC, these rules can be created and configured through the Business 360 Console interface.

• Exact Match Rules: These rules compare records using a simple “equals” condition. For instance, an exact match rule could check if the first name and last name fields are identical in two records.

• Fuzzy Match Rules: Fuzzy match rules, often based on probabilistic algorithms, allow for minor variations in the data (e.g., typos, abbreviations). These are ideal for matching names or addresses where slight inconsistencies are common.

• Algorithms like Levenshtein distance, Soundex, or Double Metaphone can be used.

• Weighted Matching: For more sophisticated matching, each field can be assigned a weight, indicating its importance in determining a match. For example, an email match might have more weight than a phone number match.

• Thresholds: A match rule also defines a threshold score, which determines the cutoff point for when two records should be considered a match. If the total match score exceeds the threshold, the records are considered potential duplicates.

b. Configuring Survivorship Rules

Survivorship rules are essential for determining which values will be retained when records are merged.

• Most Recent: Retain values from the record with the most recent update.

• Most Complete: Choose values from the record that has the most complete set of information (fewest nulls or missing fields).

• Source-based: Give preference to certain systems of record (e.g., CRM system over a marketing database).

• Custom Rules: Custom survivorship logic can be defined using scripts or expression languages to meet specific business needs.

c. Defining Merge Strategies

• The merge strategy defines how records are consolidated once a match is identified. This could be a hard merge (where duplicate records are permanently deleted and only the golden record remains) or a soft merge (where records are logically linked, but both are retained for audit and tracking purposes).

3. Cloud Application Integration in Match and Merge

In Informatica IDMC, Cloud Application Integration (CAI) is used to automate and orchestrate the match and merge processes. Cloud Application Integration allows you to create sophisticated workflows for real-time, event-driven, or batch-driven match and merge operations.

a. Key Components of CAI

• Processes and Services: CAI provides prebuilt processes or custom-built processes that handle events (e.g., new records created) and trigger match and merge jobs.

• Business Process Management: You can orchestrate the entire customer data flow by using CAI to manage how and when records are matched and merged based on predefined criteria or user input.

• Real-Time Integration: CAI supports real-time matching, where data coming in from different systems (e.g., CRM, e-commerce platforms) is automatically deduplicated and consolidated into the master record as soon as it is ingested into IDMC.

b. Steps for Cloud Application Integration

1. Triggering Match Process: CAI workflows can be set up to initiate the match process when new data is imported, updated, or synchronized from external sources. For example, a batch of customer records from a CRM system can trigger the match job.

2. Handling Match Results: Once potential matches are identified, CAI workflows can determine whether to automatically merge the records or send them for manual review.

3. Merge Execution: If the match job identifies duplicate records, CAI can trigger a merge process based on predefined merge strategies and survivorship rules.

4. Data Stewardship Involvement: In more complex scenarios, CAI can notify data stewards when manual intervention is required (e.g., for borderline matches that need human review).

c. Automating Matching and Merging with Real-Time Updates

CAI can integrate with external systems using connectors to keep master data up to date across different environments. For example:

• New customer records from an e-commerce platform can be automatically compared with existing records in IDMC to determine if they represent new customers or duplicates.

• Based on the match results, CAI can trigger a workflow that either updates the master record or adds a new record to the system.

4. Best Practices for Match and Merge in Informatica IDMC

• Define Clear Match Rules: Start with exact match rules for critical fields (such as customer ID) and add fuzzy rules for fields prone to variations (e.g., name and address).

• Test Match Thresholds: Experiment with match scores and thresholds to fine-tune the balance between over-merging (false positives) and under-merging (false negatives).

• Monitor Performance: Match and merge operations can be resource-intensive, especially with large datasets. Use IDMC’s built-in monitoring tools to track the performance and optimize configurations.

• Data Stewardship: Set up workflows that allow data stewards to review borderline cases or suspicious matches to ensure high data quality.

The Match and Merge process in Informatica IDMC provides a robust framework for deduplicating and consolidating customer data, ensuring that organizations can achieve a 360-degree view of their customers. However, to get the most value from this functionality, it’s essential to configure match rules, survivorship logic, and cloud workflows thoughtfully. By leveraging Informatica IDMC’s Cloud Application Integration features, organizations can automate and streamline their data unification processes while ensuring high-quality, reliable, and accurate customer records.

• Informatica IDMC: IDMC, being cloud-native, requires continuous internet access. Any disruption in connectivity can lead to downtime, hampering critical operations. Additionally, offline access is not possible in a cloud-hosted environment, which might be a concern for some businesses.

6. Data Latency and Real-Time Synchronization

• On-Premise: The on-premise version typically allows for near real-time synchronization of data since it can communicate directly with other local systems. For industries that require real-time customer insights (e.g., financial transactions or retail), this is crucial.

• Informatica IDMC: IDMC may introduce data latency due to its reliance on cloud services. Data synchronization between IDMC and on-premise systems or even between different cloud services could be slower, especially if large datasets or frequent updates are involved.

7. Dependency on Cloud Vendor

• On-Premise: With the on-premise setup, organizations have full control over their infrastructure and system updates. They can decide when and how to upgrade or apply patches, ensuring minimal disruption to operations.

• Informatica IDMC: IDMC customers are dependent on the cloud vendor for upgrades, maintenance, and patches. While the cloud platform ensures up-to-date software, users have less control over when updates are rolled out, which might introduce operational disruptions.

8. Cost Structure

• On-Premise: Though initial capital investment is high for on-premise systems (in terms of hardware, software, and maintenance), ongoing costs can be more predictable. Companies can scale their systems as needed without recurring subscription fees.

• Informatica IDMC: IDMC operates on a subscription model, which may seem cost-efficient initially. However, for businesses with high data processing needs or heavy customization requirements, costs can increase rapidly due to tier-based pricing structures for compute, storage, and additional services.

9. Audit and Compliance

• On-Premise: Many organizations prefer on-premise systems for compliance purposes, as they have full control over audit trails, logs, and governance rules. Regulatory compliance is often easier to manage locally.

• Informatica IDMC: While IDMC provides auditing and logging capabilities, managing compliance across different regions with varying data governance laws can be more complicated in a cloud environment, particularly when data is stored across multiple data centers globally.

The shift from on-premise to cloud-based platforms like Informatica IDMC’s Customer 360 offers significant advantages in terms of scalability, accessibility, and reduced infrastructure costs. However, for organizations with complex customizations, high security demands, or significant legacy system integrations, the on-premise version of Customer 360 still offers benefits that the cloud version cannot fully replicate. Organizations must carefully weigh these limitations against their operational needs when choosing between Informatica IDMC and the on-premise version of Customer 360.
