Database Management Systems

A book-shaped table of contents for DBMS: relational foundations through SQL mastery, storage internals, transactions, distributed databases, NoSQL, and MAANG interview prep — cross-linking existing system-design/patterns notes instead of duplicating them.

1 — Physical Storage

Covers how data is physically laid out on disk — pages, blocks, records, slotted pages, heap files, and clustered storage.

2 — Indexing

Covers why indexes exist and the major index types — clustered, non-clustered, composite, covering, partial, and bitmap.

3 — B-Trees

Covers B-tree and B+-tree structure, insert/delete operations, and why B+-trees are favored for range queries.
