CS-340 explores key topics such as network architecture, client-server models, and database connectivity. Students learn how to apply database systems concepts and principles to develop client/server applications that interface client-side code with databases, working with tools like SQL Server and Visual Studio, and applying methodologies such as Agile. The course covers full-stack basics with MongoDB and Python, building a CRUD module for a dataset and wiring it into an interactive dashboard using the Dash framework.
Connecting client-side code to real databases
The course's core skill is building the actual interface between client-side code and a database, ensuring students understand not just databases or client applications in isolation, but how the two genuinely connect and communicate.
Full-stack practice with real, current tools
CS-340 uses genuinely current, professionally relevant tools, MongoDB, Python, SQL Server, Visual Studio, the Dash framework, giving students hands-on full-stack development experience rather than only theoretical client/server architecture knowledge.

Worked example: CRUD as the foundation of client/server interaction
- Isolated pieces: A database that stores data and a client interface that displays a form
- Connected CRUD module: Client-side code that can Create, Read, Update, and Delete records directly in the database
- Lesson: CS-340 teaches that this CRUD connection is the fundamental building block of nearly every real client/server application

Frequently asked questions
Client/server architecture becomes far more concrete and genuinely learnable when built with real, current, professionally relevant tools. MongoDB for the database layer, Python for the application logic, Dash for the interactive front-end, since students then experience an actual working full-stack application rather than just diagramming client/server architecture theoretically. CS-340 uses this real toolchain because building a genuinely functioning CRUD-based dashboard demonstrates practical competency that abstract architectural discussion alone can't provide.
Nearly every real client/server application, regardless of its specific purpose, needs some way for client-side code to create new records, retrieve existing data, update information, and delete records in the underlying database, making CRUD operations the fundamental building block that almost all client/server interaction is built from. CS-340 centers its practical project on CRUD because mastering this foundational pattern transfers directly to building virtually any other client/server application afterward.
