What are the dimensions that are slowly changing?
Slowly Changing Dimensions are dimensions that alter over time (SCD).
Dimension-Type 1 (Slowly Changing): This has just current records.
Slowly Changing Dimension-Type2: This kind includes both current and historical records.
Slowly Changing Dimension-Type3: Which has one previous record and one current record

What is the cost of Informatica IDQ, including training and software access ( informatica idq tutorials)?


The cost of training varies by vendor, but I believe it should not surpass $170.
IDQ Interview Questions For Experienced!

 

Name four output files that the information server creates during the session running?
Session Log, Workflow Log, Errors Log, Bad file

 

What are the four output files created by the information server throughout the session?
Session logs, workflow logs, informatica idq tutorials, errors logs, and bad files are all examples of logs.

 

What is the purpose of using stored procedure transformation?
An important tool for populating and managing databases is a stored procedure transformation.

 

What is the distinction between a static and a dynamic cache?
When compared to static cache, dynamic cache [informatica idq tutorials] degrades performance.
Such things are not visible in a static cache. Simply enter info as many times as it appears.

 

What is the difference between mapping and sessions?
Mapping is a collection of source and target definitions that are connected by transformation object that define the rules for transformation.
informatica idq tutorials
It is a set of instructions that describe how and when to move data from source to target.

 

What is the command for running a batch?
informatica idq tutorials
pmcmd is a command that is used to start a batch.

 

What does it mean to be data-driven?
The Informatica server uses update strategy transformations in the session mapping to determine how to flag records for insert, informatica idq tutorials update, delete, or reject.

 

What is the repository for the power center?
To construct a data mart domain, you can use the PowerCenter repository to communicate metadata between repositories.

 

Can you tell me what the parameter file is [ informatica idq tutorials] ?
A parameter file is a text file that is created by text editors like word pad or notepad. In the parameter file, you can set the following values.
• session parameters • mapping parameters • mapping variables

 

How do you distinguish between a Router and a Filter?
Ans:Router Filter
The incoming records are divided into numerous groups by the router transformation based on some criterion. These kinds of groups can be mutually beneficial (Different groups may contain same record) Filter transformation restricts or blocks the incoming recordset based on one given condition.
Filtering restricts or blocks the incoming recordset depending on a single criteria(informatica idq tutorials). Filter transformation does not have a default group. If one record does not match filter condition, the record is blocked
CASE.. WHEN statement in SQL (Or Switch().. Case statement in C) is how the Router works. Router acts like CASE.. WHEN statement in SQL (Or Switch().. Case statement in C)

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.
