BiblioOn
library management portal
source code: https://github.com/joaoesteves10/BiblioOn
Context
Library management portal built for the Web Applications and Databases Lab course, with three access tiers: anonymous visitors (public catalogue browsing), authenticated readers and librarians (loans, history), and administrators (account approval, permission management). Access control is built on ASP.NET Identity, with custom roles layered on top of its native tables.
Technical challenges
- librarian approval flow — anyone registering as a librarian gets the PreBibliotecario role until an administrator activates the account
- banning without losing history — a banned reader becomes LeitorBanido, losing access to loans, but their history and data stay intact
- library data model — books, copies, loans and users, each with their own rules
