Aryan Lokesh and Punita K describe the architecture where queries flow through an SQL parser and execution layer into a storage engine with a write-ahead log for durability and recovery that rebuilds indexes after failures. They demonstrate a deployed web interface that supports create table, insert, select, and drop table, showing inserted rows and an empty set after deletion. The implementation uses a custom binary record format with a CRC32 checksum and an append-only persistent storage with an in-memory index, plus an interactive CLI and TCP client server supporting core SQL and transaction commands.</description></oembed>
