Technical Perspective: In-Situ Database Management
"NoDB: Efficient Query Execution on Raw Data Files" investigates extending a DBMS so it can use the file data in situ, without having to load it first.
From Communications of the ACM
NoDB: Efficient Query Execution on Raw Data Files
We here present the design and roadmap of a new paradigm in database systems, called NoDB, which do not require data loading while still maintaining the whole feature...
