As criminals develop increasingly sophisticated methods of hacking web systems and databases, developers must know how to build those systems securely to prevent breaches. This course teaches the art of building reliable and secure data-intensive back-end systems. You will learn how to craft APIs for usability, apply techniques to strengthen their security, choose between database design alternatives, and unlock concurrent, scalable programming.
Throughout this course, (the second in the Back-End Development Certificate), you’ll further hone your programming skills, learning to sidestep common pitfalls. You’ll also continue to sharpen your architectural thinking and clean coding skills. The course focuses on:
- Developing web services and user-friendly APIs
- Delving deeper into reusable patterns and standard solutions
- Securing back ends
- Managing sessions and permissions
- Storing and retrieving data in document and relational databases
- Concurrent and asynchronous programming
This course allows learners to work at their own pace and features optional, live drop-in sessions.
Learning outcomes
- Build a secure web service backed by a well-designed database
- Evaluate alternative data storage strategies
- Describe architectural patterns and know when to use them
- Apply asynchronous programming skills to build scalable web back ends
- Identify areas and strategies for continuous improvement of coding skills
