Even though the performance of the prototype is competitive with that of a conventional system, suggestions for improvement are presented. ... This paper suggests that more powerful data base systems (DBMS) can be built by supporting data base procedures as full fledged data base objects. ... Then, in Section 3 we review briefly how to extend one query language with necessary facilities to use procedures. ...doi:10.1145/27629.27631 fatcat:i7qldpari5eqpnou3kqcn3nl3a
The proposed system extends the functionalities of the structured query language SQL with new functions that are able to create new feature extraction procedures, new feature vectors as combinations of ... To validate the concepts and resources available in the proposed extended RDBMS, we propose a CBIR system applied to the analysis of mammograms using PostgreSQL-IE. ... The Extended Database Catalog The extended database catalog for PostgreSQL-IE is a database, called extended_template1, created using template1 as the template, with a set of 12 internal functions written ...doi:10.1007/s10278-007-9097-5 pmid:18214614 pmcid:PMC3043679 fatcat:ccfvtpygtbbvhjnft4w4txlvcu

Stored procedures are an important feature of all major database systems that allows to execute application logic within database servers. ... This paper reports on experiences to implement a popular scientific algorithm, the Basic Local Alignment Search Tool (BLAST), as stored procedures within a relational database. ... All major commercial database engines support stored procedures and even some open source database systems recently extended into this direction (e.g. PostgreSQL 8 or MySQL 5). ...doi:10.1007/11733836_58 fatcat:e2u34mucpbecdper6gxsnpir64

To achieve such a goal, database and system designers should distinguish what is information and what is knowledge for the system's domain of application. ... The intension of this paper is to point out that both Knowledge and Information can be persisted within ordinary database management systems. ... For example, we will have a system with extensible set of Predefined Queries. ...doi:10.1016/j.sbspro.2014.07.118 fatcat:d33sxcfzhnbejmcbngetwphahi

Description of GLIDE In this section a schematic description of GLIDE is given from the five points of view mentioned: as a language, a database system, a geometric modeling system, a graphics system, ... Benefits also arise from making the transition easier between using the system and extending it so that more users may be seduced into using more general features as they become more confident with the ...
To evaluate these two important features of IoT databases, we propose IoTDataBench and update four aspects of TPCx-IoT, i.e., data generation, workloads, metrics and test procedures. ... Preliminary evaluation results show systems that fail to effectively compress data or flexibly scale can negatively affect the redesigned metrics, while systems with high compression ratios and linear ...
