SAP PowerDesigner Online Test

The SAP PowerDesigner Test makes use of scenario-based questions to test for on-the-job skills as opposed to theoretical knowledge, ensuring that candidates who do well on this screening test have the relavant skills. The questions are designed to covered following on-the-job aspects:

• Designing and implementing Physical Data Models using SAP PowerDesigner
• Developing Conceptual Data Models in SAP PowerDesigner
• Creating and managing Logical Data Models in SAP PowerDesigner
• Understanding and utilizing Power Designer CDM functionalities
• Using Generation Template Language (GTL) to generate code from models in SAP PowerDesigner
• Proficiency in PDM tools and techniques
• Applying best practices in PDM design and development
• Analyzing and merging models in SAP PowerDesigner
• Creating and managing data dictionaries in SAP PowerDesigner
• Understanding and implementing relationships and associations in SAP PowerDesigner

Once the test is sent to a candidate, the candidate receives a link in email to take the test. For each candidate, you will receive a detailed report with skills breakdown and benchmarks to shortlist the top candidates from your pool.

• PDM

  PDM stands for Physical Data Model. It is a visual representation of the database structure that defines how data is stored, organized, and accessed. Measuring PDM skills in this test helps assess the candidate's ability to design and optimize database models.

• Generation Template Language (GTL)

  GTL is a scripting language used in PowerDesigner to automatically generate documents, code, or other artifacts based on the model. Evaluating GTL skills in this test helps gauge the candidate's proficiency in creating customized templates and automating repetitive tasks.

• Merging Model

  Merging models in PowerDesigner involves combining multiple data models into a single model while resolving conflicts and maintaining data integrity. Assessing merging model skills in this test ensures that the candidate can effectively consolidate and integrate data models from different sources.

• Power Designer CDM

  Power Designer CDM refers to the Conceptual Data Model, which is an abstract representation of the high-level business concepts and relationships in a database. Measuring Power Designer CDM skills in this test assesses the candidate's ability to translate business requirements into a conceptualized database design.

• Logical Data Model

  The Logical Data Model (LDM) represents the logical structure of data independent of any specific database management system. Evaluating LDM skills in this test helps determine the candidate's proficiency in designing the architecture and relationships of a database at a logical level.

• Physical Data Model

  The Physical Data Model (PDM) describes how data is stored and structured within a specific database management system. Assessing PDM skills in this test ensures that the candidate can effectively translate the logical data model into an efficient and optimized physical implementation.
