For each fuel, energy infrastructure data on fuel extraction, processing, storage, fuel transportation, power generation, and transmission and distribution of electricity to final energy product are reviewed. After screening, 146 unique datasets were evaluated for their spatiotemporal characteristics using ...
This thesis is based on Database2(DB2), one of the most famous products of IBM, studies the basic structure and optimazing theory of relational database, which contains database designing, parameter configuration, access path optimization and SQL optimization. 本文以IBM公司的著名关系型数据库产品...
For processing relatively large volumes of unstructured data, a MapReduce framework that provides a distributed computing platform can be employed. Unstructured data refers to data not formatted according to a format of a relational database management system. An open source implementation of the Map...
By storing feature characteristics in a relational database, possible matches can be more quickly located. In general it is not necessary to find all matching ballistic items, such as all sibling casings. A single positive match provides links to others already in the database. As an example,...
Data miningWith the wide installation of eBusiness and database softwaze in enterprises, mountains of data are accumulating in the form of relational tables. Discovering valuable information from the sea of data is of interest to researchers and managers worldwide. In this paper, an algorithm is...
Database updates are small and incremental compared to database contents. It is therefore desirable that recomputations of active relational expressions-such as views, derived data, integrity constraints, active queries, and monitors-can also be performed incrementally. An efficient algorithm for the ...
The analysis of the objects of the model of Big data in objects of NoSQL databases is presented. For distributed storage of large amounts of data there is proposed model used in the system of Google BigTable which is characteristic for incomplete relational data model and support dynamic ...

There are already many databases that incorporate graph expressions. We focus on syntactic trees in ...
