Informatica Data Quality may be a suite of applications and components that we will integrate with Informatica PowerCenter to deliver enterprise-strength data quality capability during a wide selection of scenarios.

The IDQ has the subsequent core components such as:

Data Quality Workbench
Data Quality Server

Data Quality Workbench: it’s wont to design, test, and deploy data quality processes. Workbench allows testing and executing plans as required, enabling rapid data investigation and testing of data quality methodologies.

Data Quality Server: it’s wont to enable plan and file sharing and to run programs during a networked environment. the Data Quality Server supports networking through service domains and communicates with Workbench over TCP/IP.

Both Workbench and Server install with a data Quality engine and a data Quality repository. Users cannot create or edit programs with Server, although users can run a program to any Data Quality engine independently of Workbench by runtime commands or from PowerCenter.

Users can apply parameter files, which modify program operations, to runtime commands when running data quality projects to a data Quality engine. Informatica also provides a data Quality Integration plug-in for PowerCenter.

In Data Quality, a project may be a self-contained set of data analysis or data enhancement processes.

A project consists of 1 or more of the subsequent sorts of component, such as:

Data sources provide the input file for the program.
Data sinks collect the data output from the program.
Operational components perform the data analysis or data enhancement actions on the data they receive.

IDQ has been a winner within the Data Quality (DQ) tools market. it’ll provide a look at the features these tools offer.

IDQ has two type variants, such as:

Informatica Analyst
Informatica Developer

Informatica analyst: it’s a web-based tool which will be employed by business analysts & developers to research, profile, cleanses, standardize & scorecard data in an enterprise.

Informatica developer: it’s a client-based tool where developers can create mappings to implement data quality transformations or services. This tool offers an editor where objects are often built with a good range of data quality transformations like Parser, standardizer, address validator, match-merge, etc.

Develop once & deploy anywhere: Both tools are often wont to create DQ rules or mappings and may be implemented as web services. Once the DQ transformations are deployed as services, they will be used across the enterprise and platforms.

Role of Dictionaries

Projects can make use of reference dictionaries to spot, repair, or remove inaccurate or duplicate data values. Informatica Data Quality projects can make use of three sorts of reference data.

Standard dictionary files: These files are installed with Informatica Data Quality and may be employed by various sorts of the component in Workbench. All dictionaries installed with Data Quality are text dictionaries. These are plain-text files saved in .DIC file format. they will be manually created and edited.

Database dictionaries: Informatica Data Quality users with database expertise can design and specify dictionaries that are linked to database tables, which this will be updated dynamically when the underlying data is updated.

Third-party reference data: These data files are provided by third parties and are provided by Informatica customers as premium product options. The reference data provided by third-party vendors are typically in database format.

1.How to Integrate IDQ with MDM

Data cleansing and standardization is an important aspect of any MDM project. Informatica MDM Multi-Domain Edition (MDE) provides an inexpensive number of cleansing functions out-of-the-box. However, there are requirements when the OOTB cleanse functions aren’t enough, and there’s a requirement for comprehensive functions to realize data cleansing and standardization, e.g., address validation, sequence generation. The Informatica Data Quality (IDQ) provides an in depth array of cleansing and standardization options. IDQ can easily be used alongside Informatica MDM.

There are three methods to integrate IDQ with Informatica MDM.

Informatica Platform staging
IDQ Cleanse Library
Informatica MDM as target
Informatica Platform Staging

Starting with Informatica MDM’s Multi-Domain Edition (MDE) version 10.x, Informatica has introduced a replacement feature called “Informatica Platform Staging” within MDM to integrate with IDQ (Developer Tool). This feature enables to direct stage or cleanse data using IDQ mappings to MDM’s Stage tables bypassing Landing tables.

Advantages

Stage tables are immediately available to use within the Developer tool after synchronization, eliminating the necessity to manually create physical data objects.
Changes to the synchronized structures are reflected within the Developer tool automatically.
Enables loading data into Informatica MDM’s staging tables, bypassing the landing tables.

Disadvantages

Creating a connection for every Base Object folder within the Developer tool are often inconvenient to take care of .
Hub Stage options like Delta detection, hard delete detection, and audit trails aren’t available.
System generated columns got to be populated manually.
Rejected records aren’t captured within the _REJ table of the corresponding stage table but get caught in .bad file.
Invalid lookup values aren’t rejected while data loads to stage, unlike within the Hub Stage Process. The record with invalid value gets rejected and captured by the Hub Load process.

2.IDQ Cleanse Library

IDQ allows us to make functions as operation mappings and deploys them as web service, which may then be imported in Informatica MDM Hub implementation as a replacement sort of cleansing library defined as IDQ cleanse library. This functionality allows usage of the imported IDQ cleanse functions, a bit like the other out-of-the-box cleanse function. Informatica MDM Hub acts as an internet service client application that consumes IDQ’s web services.

Advantages

Quickly build transformations in IDQ’s Informatica Developer tool instead of creating complex java functions.
Unlike Informatica Platform staging, Hub Stage process options like delta detection, hard delete detection, audit trail are available to be used.

Disadvantages

Physical data objects got to be manually created for every staging table and manually updated for any changes to the table.
IDQ function must contain all transformation logic to leverage the batching of records. If any transformation logic is additionally defined within the MDM map, then calls to the IDQ web service are going to be one record resulting in performance issues.
Web service invocations are synchronous only, which may be a priority for giant data volume.

3.Informatica MDM as target

3.1 Loading data landing tables

Informatica MDM are often used as a target for loading the datato landing tables in Informatica MDM.

Advantages

The single connection created within the Developer tool for Informatica MDM is a smaller amount cumbersome in comparison to making multiple connections with Informatica platform staging.
No got to standardize data within the Hub Stage Process.
Unlike Informatica Platform staging, Hub Stage process options – delta detection, hard delete detection, audit trail are available to use.

Disadvantages

Physical data objects got to be manually created for every landing table and manually updated for any changes to the table.
Need to develop mappings at two levels (i) source to landing and (ii) landing to staging (direct mapping).

3.2 Loading data staging tables (bypassing landing tables)

Informatica MDM are often used as a target for loading the on to staging tables in Informatica MDM, bypassing landing tables.

Advantages

The single connection created within the Developer tool for Informatica MDM is a smaller amount cumbersome in comparison to making multiple connections with Informatica platform staging.
It are often used for the lower version of Informatica MDM, where the Informatica Platform staging option isn’t available.

Disadvantages

Physical data objects got to be manually created for every staging table and manually updated for any changes to the table.
Hub Stage Delta detection, hard delete detection, and audit trails options aren’t available.
System generated columns got to be populated manually.
Rejected records aren’t captured within the _REJ table of the corresponding stage table but get caught in .bad file.
Invalid lookup values aren’t rejected while data loads to stage, unlike within the Hub Stage Process. The record with invalid value gets rejected and captured by the Hub Load process.
