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.
