Data Transformation
In data warehouses, it is common to map discrete data values to a set of ranges. This makes it easier to write queries that involve a range of discrete values. Read More
Test Data
A universally unique identifier, or UUID, is an identifier standard used in software construction and data processing. The main function of the UUID is to be a unique identifier in registries, databases, or larger data stores like a data warehouse. Read More

Dimensional data that change slowly or unpredictably are captured in Slowly Changing Dimensions (SCD) analyses. In a data warehouse environment, a dimension table has a primary key that uniquely identifies each record and other pieces of information that are known as the dimensional data. Read More

Introduction: As with multiple BI platforms discussed throughout this section of the IRI blog site, this article analyzes the relative data preparation performance (and benefit) of using its external data wrangling engine – via the IRI CoSort product or Voracity platform — with QlikView when ‘big data’ sources are involved.

Data Migration
In the course of legacy platform and/or application migration, COBOL users often need to convert their binary and index files into a human-readable, ASCII-numeric target. One of these older formats is the ACUCOBOL Vision1 file, which we discussed previously in this article. Read More
