B+-tree Index Optimization by Exploiting Internal Parallelism of Flash-based Solid State Drives Previous research addressed the potential problems of the hard-disk oriented design of DBMSs of flashSSDs. In this paper, we focus on exploiting potential benefits of flashSSDs. First, we examine the...
DBMS like MySQL can be extended by user-defined functions [11]. Extensible DBMS like SECONDO [12] can be extended by complete operators or new data models. User-defined filters (see Sect. 3.6) extend the query processor of BBoxDB. In BBoxDB Streams, these UDFs can be used to process ...

While B+Tree is the most important index structure for disk-based database management systems (DBMS), T*-Tree is optimized for main memory access and widely used for in memory database system (IMDB). however, the prior researches made performance evaluation between T*-Tree and B+Tree on ...
for solving problems recursively by trying to build a solution incrementally, one piece at a time, removing those solutions that fail to satisfy the constraints of the problem at any point in time (by time, here, is referred to the time elapsed till reaching any level of the search tree)....
