Erroneous or incomplete data generated from various sources can have direct impact in business analysis. Extracted data from sources need to load into data warehouse after required transformation to reduce error and minimize data loss. This process is also known as Extraction-Transformation-Loading (ETL). High-level view of the system activities can be visualized by conceptual modeling of ETL process. It provides the advantage of pre-identification of system error, cost minimization, scope and risk assessment etc. A new modeling approach is proposed for conceptualization ETL process by using a standard Systems Modeling Language (SysML). For handling increasing complexity of any system model, it is preferable to go through verification and validation process in early stage of system development. In this article, the authors' previous work is extended by presenting a MBSE based approach to automate the SysML model's validation by using No Magic simulator. Here, the main objective is to overcome the gap between modeling and simulation and to examine the performance of the proposed SysML model. The usefulness of the authors' approach is exhibited by using a use case scenario.
