A Demonstration of SciDB: A Science-Oriented DBMS
نویسندگان
چکیده
In CIDR 2009, we presented a collection of requirements for SciDB, a DBMS that would meet the needs of scientific users. These included a nested-array data model, sciencespecific operations such as regrid, and support for uncertainty, lineage, and named versions. In this paper, we present an overview of SciDB’s key features and outline a demonstration of the first version of SciDB on data and operations from one of our lighthouse users, the Large Synoptic Survey Telescope (LSST).

SciDB DBMS Research at M.I.T
This paper presents a snapshot of some of our scientific DBMS research at M.I.T. as part of the Intel Science and Technology Center on Big Data. We focus our efforts primarily on SciDB, although some of our work can be used for any backend DBMS. We summarize our work on making SciDB elastic, providing skew-aware join strategies, and producing scalable visualizations of scientific data.
متن کاملThe Gamma Operator for Big Data Summarization on an Array DBMS
SciDB is a parallel array DBMS that provides multidimensional arrays, a query language and basic ACID properties. In this paper, we introduce a summarization matrix operator that computes sufficient statistics in one pass and in parallel on an array DBMS. Such sufficient statistics benefit a big family of statistical and machine learning models, including PCA, linear regression and variable sel...
متن کاملDatabase System Support of Simulation Data
Supported by increasingly efficient HPC infra-structure, numerical simulations are rapidly expanding to fields such as oil and gas, medicine and meteorology. As simulations become more precise and cover longer periods of time, they may produce files with terabytes of data that need to be efficiently analyzed. In this paper, we investigate techniques for managing such data using an array DBMS. W...
متن کاملReport from the SciDB Workshop
A mini-workshop with representatives from the data-driven science and database research communities was organized in response to suggestions at the first XLDB Workshop. The goal was to develop common requirements and primitives for a next-generation database management system that scientists would use, including those from high-energy physics, astronomy, biology, geoscience and fusion, in order...
متن کاملDynamic Reduction of Query Result Sets for Interactive Visualization
Modern database management systems (DBMS) have been designed to efficiently store, manage and perform computations on massive amounts of data. In contrast, many existing visualization systems do not scale seamlessly from small data sets to enormous ones. We have designed a threetiered visualization system called ScalaR to deal with this issue. ScalaR dynamically performs resolution reduction wh...
