What is recorded here?
Developed multigranularity locking with intention modes and described degrees of consistency for shared databases, making concurrency and locking-overhead tradeoffs explicit.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
The record is the exact four-author 1975 conference paper. It does not absorb later SQL isolation-level standards, two-phase locking as a whole, implementation-specific lock managers or all transaction theory.
