Before we look into MDM interview questions, it is important to have an overview of this challenging field. It is the management of some essential data resource of a business group. Way back in , the idea of Master Data Management was coined when Enterprise Resource Planning ERP applications and data warehousing became prominent in many business groups. With the advancement, the volumes of data and databases increased which resulted in the addition of more fraction of applications for users to process and view the data.
Hence, it was necessary to ensure that the right master data definitions were used so that there are distinct data with no variation, duplications or obsolete date. Let us take the example of Customer Information. In a large enterprise, there is a probability of multiple databases of the customer which are controlled by multiple applications. So, one customer can receive emails or messages from the same enterprise. As the information grows, the master data is bound to include other important data assets like the data of suppliers, products and panelists.
If master data is not properly coordinated and synchronized across the enterprise, then the prospect of MDM seems challenging. But with challenges only comes great opportunities. MDM is a methodology of allowing an organization to link all of its important data to one file, which is called a master file. This file provides a common base of reference. When implemented properly, MDM networks data sharing among individuals and enterprise. People associated with IT and Computers get the concept easily.
Business official understands MDM but not up to the level of former because businessmen are more interested in only knowing what benefit MDM can bring to their group. Dimensional Modelling has two types of tables which is distinct from the third normal form. Here, Facts table containing the measurements of the business and Dimension table containing the context viz. The use of Data warehouse becomes essential because a Data Analyst can perform complex queries and analysis like data mining which makes use of a data warehouse.
At a single point in time, we are able to present a clear image of business conditions with the help of Data warehousing which otherwise contains a wide variety of data.
PowerCenter is the data integration software of Informatica Corporation. The usage of this software allows loading the data into centralized locations such as data warehouses. Data taken from multiple sources can be used as per the business requirements. Conference of MDM was hosted by Gartner for the first time and they managed to pull five hundred attendees in the conference.
It is very necessary to host such conferences. For example, the budgets of the Pharmaceutical and Financial services industries are increasing. Gartner also forecasted that seventy percent of two thousand global companies will have an MDM solution, by the year The primary issue is Funding while selling the project is a secondary issue.
The management is actively looking for an investment return. They want MDM to be benefitting and profitable for their business. Mapping represents the flow of data between targets and sources. A mapping is a set of target definitions and source linked by objects of transformation which define the data transformation rules. A Mapplet is a reusable object containing a set of transformations.
It enables to reuse that transformation logic in multiple mappings. A transformation is an object that generates, modifies or passes data. So, it is a repository object. Transformations in a mapping represent the operations the Integration Service performs certain operations on the data in a mapping that are represented. Transformation ports are linked in a mapping or mapplet and the data passes through these ports.
Data Mining is the process of analyzing data from different perspectives and summarizing it into useful information. The measurements of business processes are present in the fact table. The foreign keys for the dimension tables are also contained by the facts table. Whereas textual attributes of measurements stored in the facts tables are included in the dimensional table.
A dimensional table is a cumulation of categories, hierarchies, and logic. The repository can also be exported and imported into the new environment.
We can also export each mapping to XML and import in a new environment. Informatica deployment groups can also be used. OLTP is an application that modifies data the instance it receives and has a large number of concurrent users.
While OLAP is an application that collects, manages, processes and presents multidimensional data for analysis and management purposes. A Mapping Parameter is defined by us before running the session and its value remains until the end of the session which makes it a static value.
Whereas a Mapping Variable changes anytime during the session and that is why it is dynamic. The initial value of the variable is read by the PowerCenter before the session starts and its value changes using the variable functions.
You should continue with MDM if you have an inclination towards it. MDM was about structured data traditionally. MDM was an on-premise application earlier. More organizations are asking for cloud deployment to lower costs today. The future is going to be challenging as there would be more deployments of MDM on the cloud. To conclude, to work in the MDM team you need to update your knowledge frequently.
Thank you. It is an application that modifies the data, the instance receives and it has a large number of recurrent users. It is an application that collects, manage, process and presents the multidimensional data for management and analytics purposes.
