The main goal of this study was to devise and deploy a practical relational database tailored for use in the International Employee Immigration domain, addressing the persistent challenges faced by companies in this industry. These companies have consistently voiced concerns about the laborious nature of the mandatory international employee data input procedures mandated by law. Upon a comprehensive examination of the industry-wide issue, it became evident that there was substantial data redundancy, presenting an opportunity for efficiency through data reuse facilitated by a relational database. The implementation of this relational database has demonstrated a 50% reduction in the time required for the data input process, yielding significant cost savings across the entire industry. Additionally, the database incorporates a central analytics platform with extensive potential for analyzing employee information, studying citizenship patterns, and streamlining data management. The database design considered the specific data fields mandated by the United States Citizenship and Immigration Services for VISA and Green Card renewal processes. Extensive Entity-Relationship (EER) and Unified Modeling Language (UML) diagrams were crafted, followed by the translation of the conceptual model into a relational model, complete with the necessary primary and foreign keys. The full implementation of this database was executed using MySQL, with a prototype adapted for MongoDB to explore the feasibility of employing this database in a NoSQL environment. The resulting database has proven to be highly successful. Integration with Python has unlocked expansive analytics capabilities, some of which are showcased in the study. These analytical queries can be instrumental in monitoring and managing employees effectively. The subsequent phase of enhancement for this SQL Database involves the incorporation of Data Governance measures. Following this, the project aims to be presented to U.S. companies seeking simplified solutions for international employee management processes.
