Management by Hierarchy [ Informatica MDM ]

In order to manage enormous volumes of data in any business, data must be organized into hierarchies. Companies typically use a variety of tools to define and manage various sorts of hierarchical relationships, based on the data at hand. For example, a corporation might have a human resources (HR) program that allows employees, supervisors  Informatica MDM, and groups to construct organizational hierarchies for personnel data. It’s possible that the same company has a customer. Relationship Management (CRM) application to define and create sales territories by geographical type. Companies may use a third program, such as an Enterprise Resource Planning (ERP) application, to establish product hierarchies in some circumstances.
Hierarchy Manager Informatica MDM  allows you to combine multiple corporate hierarchies into a single product. Bringing together company hierarchies highlights and simplifies the relationships between those hierarchies throughout the organization.


What is the Role of a Hierarchy Manager [ Informatica MDM ]?

The Hierarchy Manager (HM) uses relationship data to define the links, affiliations, and hierarchies between different entities (such as individual to the organization, organization to organization, or individuals within households). This introduction outlines the issues that businesses confront when it comes to data management Informatica MDM, shows how HM manages data from multiple sources and explains how HM works. During transactions, Hierarchy Manager defines and manipulates both transactional and master data.


Transactional data
Transactional data is often stored in a single system and represents actions performed by a single application Informatica MDM, such as withdrawals, deposits, and fund transfers in banking.

Data from the master (also known as reference data)
Master data is typically made of common, core entities, as well as their properties and values Informatica MDM, and is stored in two or more systems that may or may not communicate with one another.

For example, information about a person who opens a checking and savings account at different times may be stored in two different systems Informatica MDM, making it more difficult to manage customer data throughout the entire bank system.

In the below example, the data has been filtered and structured to display the sphere of influence of John Lewis

Data Management Challenges in Enterprise Systems


There are multiple reasons for this:
Informatica MDM 
Master data (reference and relationship data) is created and stored in many silos (applications, data warehouses, data marts, external sources, or channels), which frequently contain duplicate or conflicting data.

Many of these data sources have proprietary fixed data models that offer barriers to unification; • Separate segments of the business control different portions of master data, which are isolated by organizational boundaries.
Why Managing changes to dispersed master data is complex.

The Lewis family has many different sorts of relationships with many different kinds of people and other types of entities, such as trusts, in the following scenario. The data is stored in six different systems Informatica MDM. The discoverable relationships within the data are depicted in the diagram below.

Relationships and Types of Relationships
HM defines and manipulates data using relationships and relationship types throughout transactions. Before working in the Hierarchy Manager tool, database designers build entities, relationships, entity and relationship types, and profiles in the Hierarchies tool.

The affiliation between two specified entities is described by a relationship. The following properties are used to define Hierarchy Manager relationships.:


Type of RelationshipThis Hierarchy Manager relationship pertains to a broad category of relationships.
Type of HirerachyThe type of hierarchy that this relationship belongs to.
Start and end datesThe time span during which the relationship is deemed active. (If the current date falls outside of that time frame, the relationship is not removed; instead, it is marked as inactive.)
A customer implementation can declare any number of additional attributes to provide additional information about a relationship. For instance, status code and ownership percentage.


You can define associations widely or narrowly depending on the criteria. The amount of HM relationships that an entity can have is unrestricted in Hierarchy Manager.

Relationship kinds are broad categories of partnerships. The following is defined by the relationship type:
• Entities that can be involved in this type of interaction
• The relationship’s direction (if any)
• The way the relationship is presented

Question and Answer

Master data management (MDM) is a comprehensive method of enabling an enterprise to link all of its critical data to one file, called a master file, that provides a common point of reference. When properly done, MDM streamlines data sharing among personnel and departments.

  • There are two types of table involved in Dimensional Modeling and this model concept is different from the third normal form. Dimensional data model concept makes use of facts table containing the measurements of the business and dimension table containing the measurement context.

A data movement mode determines how the power center server handles the character data. We choose the data movement in the Informatica server configuration settings. Two types of data movement modes available in Informatica.

It’s a matter of awareness and the problem becoming urgent. We are seeing budgets increased and greater success in closing deals, particularly in the Pharmaceutical and Financial services industries. Forrester predicts MDM will be $6 billion markets by 2010, which is a 60 percent growth rate over the $1 billion MDM market last year. Gartner forecasted that 70 percent of Global 2000 companies will have an MDM solution by the year 2010. These are pretty big numbers

We can export repository and import into the new environment
We can use Informatica deployment groups
We can Copy folders/objects
We can Export each mapping to XML and import in a new environment

It is a repository object that helps in generating, modifying or passing data. In a mapping, transformations make a representation of the operations integrated with service performs on the data. All the data goes by transformation ports that are only linked with maple or mapping.

Foreign keys of dimension tables are the primary keys of entity tables.
Foreign keys of facts tables are the primary keys of dimension tables.

A Mapplet is a reusable object that contains a set of transformations and enables to reuse that transformation logic in multiple mappings.

There are two different ways to load data in dimension tables.
Conventional (Slow) – All the constraints and keys are validated against the data before, it is loaded; this way data integrity is maintained.
Direct (Fast) – All the constraints and keys are disabled before the data is loaded. Once data is loaded, it is validated against all the constraints and keys. If data is found invalid or dirty it is not included in the index and all future processes are skipped on this data. 

Designed by Informatica Corporation, it is data integration software providing an environment that lets data loading into a centralized location like a data warehouse. From here, data can be easily extracted from an array of sources, also can be transformed as per the business logic and then can be easily loaded into files as well as relation targets.
