In Informatica Master Data Management (MDM), ROWID_OBJECT and ORIG_ROWID_OBJECT are critical identifiers within the MDM data model, particularly within the context of data storage and entity resolution.
ROWID_OBJECT
Definition: ROWID_OBJECT is a unique identifier assigned to each record in a base object table in Informatica MDM. It is automatically generated by the system and is used to uniquely identify each record in the MDM repository.
Significance:
Uniqueness: Ensures that each record can be uniquely identified within the MDM system.
Record Tracking: Facilitates tracking and managing records within the MDM system.
Entity Resolution: Plays a crucial role in the matching and merging processes. When records are matched and merged, the surviving record retains its ROWID_OBJECT, ensuring consistent tracking of the master record.
ORIG_ROWID_OBJECT
Definition: ORIG_ROWID_OBJECT represents the original ROWID_OBJECT of a record before it was merged into another record. When records are consolidated or merged in the MDM process, the ORIG_ROWID_OBJECT helps in maintaining a reference to the original record's identifier.
Significance:
Audit Trail: Provides an audit trail by retaining the original identifier of records that have been merged. This is crucial for data lineage and historical tracking.
Reference Integrity: Ensures that even after records are merged, there is a way to trace back to the original records, which is important for understanding the data's history and origin.
Reconciliation: Aids in reconciling merged records with their original sources, making it easier to manage and understand the transformation and consolidation processes that the data has undergone.
So, ROWID_OBJECT ensures each record in the MDM system is uniquely identifiable, while ORIG_ROWID_OBJECT maintains a link to the original record after merging, providing critical traceability and auditability in the MDM processes.

In Informatica Master Data Management (MDM), the concepts of landing tables, staging tables, and Base Object tables are integral to the data integration and management process. Here's an overview of each:
Landing Table:
The landing table is the initial point where raw data from various source systems is loaded.
It acts as a temporary storage area where data is brought in without any transformations or validation.
The data in the landing table is usually in the same format as it was in the source system.
It allows for an easy inspection and validation of incoming data before it moves further in the ETL (Extract, Transform, Load) process.
Staging Table:
The staging table is used for data processing, transformation, and validation.
Data is loaded from the landing table to the staging table, where it is cleaned, standardized, and prepared for loading into the Base Object table.
This step may involve deduplication, data quality checks, and application of business rules.
Staging tables ensure that only high-quality and standardized data proceeds to the Base Object table.
Base Object Table:
The Base Object table is the core table in Informatica MDM where the consolidated and master version of the data is stored.
It represents the golden record or the single source of truth for a particular business entity (e.g., customer, product, supplier).
The data in the Base Object table is typically enriched and merged from multiple source systems, providing a complete and accurate view of the entity.
Base Object tables support further MDM functionalities such as match and merge, hierarchy management, and data governance.
In summary, the flow of data in Informatica MDM typically follows this sequence: Landing Table → Staging Table → Base Object Table. This process ensures that raw data is transformed and validated before becoming part of the master data repository, thereby maintaining data integrity and quality.

In Informatica Master Data Management (MDM), matching strategies are crucial for identifying duplicate records and ensuring data accuracy. Two common matching techniques are fuzzy match and exact match. Here's a detailed explanation of both:
Fuzzy Match
Fuzzy matching is used to find records that are similar but not necessarily identical. It uses algorithms to identify variations in data that may be caused by typographical errors, misspellings, or different formats. Fuzzy matching is useful in scenarios where the data might not be consistent or where slight differences in records should still be considered as matches.
Key Features of Fuzzy Match:
Similarity Scoring: It assigns a score to pairs of records based on how similar they are. The score typically ranges from 0 (no similarity) to 1 (exact match).
Tolerance for Errors: It can handle common variations like typos, abbreviations, and different naming conventions.
Flexible Matching Rules: Allows the configuration of different thresholds and rules to determine what constitutes a match.
Algorithms Used: Common algorithms include Levenshtein distance, Soundex, Metaphone, and Jaro-Winkler.
Exact Match
Exact matching, as the name suggests, is used to find records that are identical in specified fields. It requires that the values in the fields being compared are exactly the same, without any variation. Exact matching is used when precision is critical, and there is no room for errors or variations in the data.
Key Features of Exact Match:
Precision: Only matches records that are exactly the same in the specified fields.
Simple Comparison: Typically involves direct comparison of field values.
Fast Processing: Because it involves straightforward comparisons, it is generally faster than fuzzy matching.
Use Cases: Suitable for fields where exactness is essential, such as IDs, account numbers, or any field with a strict, unique identifier.
Use Cases in Informatica MDM
Fuzzy Match Use Cases:
Consolidating customer records where names might be spelled differently.
Matching addresses with slight variations in spelling or formatting.
Identifying potential duplicates in large datasets with inconsistent data entry.
Exact Match Use Cases:
Matching records based on unique identifiers like social security numbers, account numbers, or customer IDs.
Ensuring the integrity of data fields where precision is mandatory, such as product codes or serial numbers.
Fuzzy Match Examples
Names:
Record 1: John Smith
Record 2: Jon Smith
Record 3: Jhon Smyth
In a fuzzy match, all three records could be considered similar enough to be matched, despite the slight variations in spelling.
Addresses:
Record 1: 123 Main St.
Record 2: 123 Main Street
Record 3: 123 Main Strt
Here, fuzzy matching would recognize these as the same address, even though the street suffix is spelled differently.
Company Names:
Record 1: ABC Corporation
Record 2: A.B.C. Corp.
Record 3: ABC Corp
Fuzzy matching algorithms can identify these as potential duplicates based on their similarity.
Exact Match Examples
Customer IDs:
Record 1: 123456
Record 2: 123456
Record 3: 654321
Exact match would only match the first two records as they have the same customer ID.
In this case, using fuzzy match for the name field, all three records might be identified as potential matches. For the email field, only records 1 and 2 would match exactly, and for the phone field, depending on the normalization of phone numbers, all three might match.
In summary, fuzzy matching is useful for finding records that are similar but not exactly the same, handling inconsistencies and variations in data, while exact matching is used for precise, identical matches in fields where accuracy is paramount.
Master data management (MDM) is a crucial component of any organization's data strategy, aimed at ensuring the uniformity, accuracy, stewardship, semantic consistency, and accountability of the enterprise’s official shared master data assets.
