By incorporating the five (5) SDLC phases, I prepared a project management template for the revised Excel Database System (SALES EXCDb Project), which included a well-organized list of activities, their respective durations, and allocated resources. Additionally, I integrated relevant settings for cost project (prorated and end) for all resources, established a new base calendar and working hours, and set a baseline for the SALES EXCDb Project. Moreover, I created a set of relational tables to store the data based on the ERD generated above, ensuring clear organization of the tables and their fields/attributes, as well as defining the primary key for each table and any necessary foreign keys. Lastly, I developed an Interactive Excel Dashboard to visualize the analysis conducted in (f) and align with the specified objectives for implementing effective data management and analysis.
