Parallel Probing of Web Databases for Top-k Query Processing
A “top-k query” specifies a set of preferred values for the attributes of a relation and expects as a result the k objects that are “closest” to the given preferences according to some distance function. In many web applications, the relation attributes are only available via probes to autonomous webaccessible sources. Probing these sources sequentially to process a top-k query is inefficient, ...
متن کاملEecient Transaction Management & Query Processing in Massive Digital Databases
We address several important issues that arise in the development of Massive Digital Database Systems (MDDSs) in which data is being added continuously and on which users pose queries on the y. News-on-demand and document retrieval systems are examples of systems that have these characteristics. Given the size of data, metadata such as index structures become even more important in these system...
متن کاملModParOpt: A Modular Query Optimizer for Multi-Query Parallel Databases
This paper presents MODPAROPT, MODular PARallel Query OPTimizer) a parallel optimizer for complex relational queries in a multi-query environment, which meets perfectly the requirements of modern database applications (e.g. decision support and data mining). The optimizers architecture was developed in a very strict modular way being therefore highly extensible. It integrates an intelligent res...
متن کاملContent-Based Query Processing for Video Databases
This paper presents a query processing strategy for the content-based video query language named CVQL. By CVQL, users can flexibly specify query predicates by the spatial and temporal relationships of the content objects. The query processing strategy evaluates the predicates and returns qualified videos or frames as results. Before the evaluation of the predicates, a preprocessing is performed...
