What will I learn?
This Computer Science Course guides you through designing a robust library backend using practical data structures, clear domain models, and efficient search indexes. You will write core algorithms in pseudocode, analyse Big-O performance, and apply proven testing, logging, and monitoring practices. Learn to handle persistence, concurrency, and scaling so your systems stay correct, reliable, and easy to maintain in real projects.
Elevify advantages
Develop skills
- Design data structures: build fast search, catalogue, and loan tracking maps.
- Write clear pseudocode: model add, search, borrow, and return workflows.
- Apply concurrency control: prevent race conditions and lost updates in code.
- Architect modular services: define clean APIs, modules, and test strategies.
- Evaluate storage options: compare DBs, caching, and scaling for library systems.
