Welcome to Data Modeling and Applications! This course introduces the student to the use of a database management system to provide the software and database necessary to upgrade a DBMS system. Database structures, applications, network, relational and hierarchical data models, applicate programs development, query systems, file security, and the role of the database administrator will be studied. In Module 1 we delve into the foundational concepts of databases, contrasting them with traditional list-based data management. We'll explore the limitations of using lists, such as redundancy and the challenges of handling multiple themes in a single list, which can lead to complex data modification issues. By understanding these challenges, you'll appreciate the necessity and benefits of transitioning to a database system, which offers a structured, efficient approach to managing complex data sets.
