Missing Data – “Nothing from nothing” – leaves something?

In TM1, missing data usually means that there is a defect in the logic of your ETL script or you need to check your SQL. In SPSS Modeler, missing values arise for a variety of reasons and they must be considered carefully. You might expect that missing values imply errors or should those records be […]

Primary Practices for Examining Data

SPSS Data Audit Node       Once data is imported into SPSS Modeler, the next step is to explore the data and to become “thoroughly acquainted” with its characteristics. Most (if not all) data will contain problems or errors such as missing information and/or invalid values. Before any real work can be done using […]

Data Consumption – Cognos TM1 vs. SPSS Modeler

In TM1, you may be used to “integer or string”, in SPSS Modeler, data gets much more interesting. In fact, you will need to be familiar with a concept known as “Field Measurement Level” and the practice of “Data Instantiation”. In TM1, data is transformed by aggregation, multiplication or division, concatenation or translation, and so […]

Importing Data into SPSS Modeler for the TM1 Developer

If you have a TM1 background it is a quick step to using SPSS Modeler -if you look for similarities in how the tools handle certain tasks like, for example, importing data. With TM1, source data is transformed and loaded into cube structures for consolidation, modeling and reporting using its ETL tool TurboIntegrator. In SPSS […]

Serviceability Auditing

The assessment team will identify the purpose and scope of the assessment prior to beginning the […]

Cognos TM1 Bulk Data Loading

Bulk Absorption Options From a pure architectural perspective, what is sometimes referred to as “bulk uploading” sometimes is (mistakenly) considered to be part of reporting or included in the data consumption component of a TM1 application design.  Loading and/or updating data is part of an applications absorption or configurations components and should be handled with […]

Performance Profiling with Cognos TM1

Profiling As my last post promised, I’m continuing the performance testing discussion with my thoughts on performance profiling. What is profiling? Profiling is the extrapolation of information about something, based on known qualities (baselines) to determine its behavior (performance) patterns. In fact, performance profiling is determining the average time and/or resources required to perform a […]

IBM Cognos TM1 Server Environments and Model Migration

IBM Cognos TM1 employs a distributed, client-server architecture that consists of the IBM Cognos TM1 server to which a combination of different clients can connect. The TM1 Server manages access to the Cognos TM1 data directory for Cognos TM1 clients. The data directory is where files are migrated from and to and this “migration of […]
