What will I learn?
This Computer Science Course takes you through building a solid library backend with practical data structures, clear domain models, and efficient search indexes. You will code core algorithms in pseudocode, check Big-O performance, and use solid testing, logging, and monitoring methods. Learn to manage persistence, concurrency, and scaling so your systems remain correct, reliable, and easy to maintain in actual projects.
Elevify advantages
Develop skills
- Design data structures: build fast search, catalog, 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.
