We are given a large database of customer transactions. Each transaction consists of items purchased by a customer in a visit. We present an e cient algorithm that generates all s...
This paper presents two algorithms for maintaining Btree index consistency in a DBMS which does not use write-ahead logging (WAL). One algorithm is similar to shadow paging, but i...
