(3) [68] shows no query performance improvements; we show speed-ups in both a big-data cluster and a DBMS. (4) [68] offers no results in the presence of data updates; we design and evaluate two maintenance techniques that can be built into transactional systems. While a query executes...
It is 7× faster than NFA in SQL Server (2019). When indexes are not available, in order to avoid expensive cross-product Joins, we make use of window constraint to virtually bucketize the input table, and rewrite the Joins into equality Joins so that each row is only joined with its ...
the fuzzy joins system is implemented inside the Microsoft™ SQL Server DBMS, which integrates the Common Language Runtime (CLR) and allows a limited set of SQL query language extensions in order to invoke various user-defined functions, such as a signature generator function, a similarity calcu...
Similarly, ProDB [13] provides a minimal adaptation of a conventional DBMS with oblivious RAM protocol on hardware enclave. Some solutions adopted other TEEs such as Arm TrustZone. DBStore [14] is an example of a DBMS that leveraged the technology to enhance the security of mobile devices. ...
