The emerging category of self-service enterprise applications motivates support for “live programming” in the database, where the user’s iterative data exploration triggers changes to installed application code and its output in real time. This paper discusses the technical challenges in supporting live programming in the database and presents the solution implemented in the LogicBlox commercia...

In this paper we propose a distributed meta-index using a peer-to-peer protocol to allow spatio-temporal queries of moving objects on a large set of distributed database servers. We present distribution and fault tolerance strategies of a meta-index that combines partial trace of object movements with aggregated data about the number of objects in the database servers. The degrees of distributi...

Data warehouses are complex systems that have to deliver highly-aggregated, high quality data from heterogeneous sources to decision makers. Due to the dynamic change in the requirements and the environment, data warehouse system rely on meta databases to control their operation and to aid their evolution. In this paper, we present an approach to assess the quality of the data warehouse via a s...

VideoSTAR Video STorage And Retrieval is an experimental video database system that gives support for sharing and reuse of video and meta data In this paper we discuss the need for a user to control the de gree of meta data sharing when searching and browsing a shared video database and we propose a way of or ganising meta data to allow such functionality This paper also presents a video query ...

conclusions according to the results of this meta-analysis, there was a high risk of nafld in women with pcos. we suggest evaluating patients with pcos regarding nafld. results we finally included seven eligible studies. according to chi-squared test, there was a significant heterogeneity (73.6%) between studies (p = 0.001). nafld prevalence was significantly higher in patients with pcos compar...

Entity Class Method Attribute Package Figure 4.1: A simplified meta-model for object-oriented systems. from existing methods. In Figure 4.1 we show a simplified depiction of the meta-model for representing entities from object-oriented systems. The use of an objectoriented language for implementation allows us to hide the fields that describe the entity and define operations by which an entity ...

In order to investigate the association between the iNOS gene polymorphisms and susceptibility to cancer, a search of English papers was done using Pubmed, the Cochrane Library, Embase, ISI Web of Science, Google (scholar) database, and all Chinese reports were conducted using CBMDisc, Chongqing VIP database, and CNKI database. A total of eight studies were included in this meta-analysis includ...

Generally, the evolution process of applications has impact on their underlining data models, thus becoming a time-consuming problem for programmers and database administrators. In this paper we address this problem within an aspect-oriented approach, which is based on a meta-model for orthogonal persistent programming systems. Applying reflection techniques, our meta-model aims to be simpler t...

We aimed to understand the extent of the pursuit for statistically significant results in the prognostic literature of cancer. We evaluated 340 articles included in prognostic marker meta-analyses (Database 1) and 1575 articles on cancer prognostic markers published in 2005 (Database 2). For each article, we examined whether the abstract reported any statistically significant prognostic effect ...
