For instance, in anobject-oriented programminglanguage, the data structure and its associated methods are bound together as part of a class definition. In non-object-oriented languages, there might be functions defined to work with the data structure, but they aren't technically part of the data...
Fingerprint/tag/pointer structure: The query results are retrieved and returned from thedistributed data storagethrough fingerprint/tag/pointer for improving search efficiency. • Reorganized database structure: The query results are retrieved through reorganizing data into other databases for improving sear...
In this work we will study the problem of the design of the "Integration Model for Distributed Database System". We particularly design the canonical model through the ontological handling of the info A Muoz,J Aguilar,R Martinez - OAI 被引量: 2发表: 2012年 Microwave Dielectric Behavior of ...
Block-Interleaved Distributed Parity 采用了块级拆分且校验信息分布式存储,即数据和其他的数据的校验信息可以存储在同一个磁盘上,但是该数据自己的校验信息不能和自己存储在用一块磁盘上 一共5块磁盘做RAID,P0~P4表示纠错位(校验信息),数据块按照(n mod 5) + 1的方式存储在5块盘上,相应数据块的校验信息存储在...
In Section “Deconstructing database storage”, we analyze the interesting storage layout parameter trade-offs and explain how these parameters and some user actions can be discovered within a DBMS. Section “Experiments” reports experimental analysis results for a variety of different databases and ...
In addition, the Entrez servers and administrators are not tolerant of large numbers of automated queries. We created the SeqHound database system to overcome these obstacles and to serve as a platform for our research [3–6]. While the Entrez servers are not presented by NCBI in an ...
NIBGF is comparable to aB-tree performance as far as the index is concerned, even in the worst case scenario, and to the BANG file performance as far as the data regions are concerned. These properties make the new structure suitable for efficient implementation of relational database ...
The full control of the Oracle database migration is taken though a single configuration file named ora2pg.conf. The format of this file consist in a directive name in upper case followed by tab character and a value. Comments are lines beginning with a #. There's no specific order to ...
A method of constructing an aid to tuning of database statements comprises a data structure (stored in a memory on a computer system) which compactly represents that information which is needed about
We have begun a long-term project to build a new kind of database and its enhanced, supporting database management system (DBMS) for international neuroscience research. Because brain research occurs world-wide, our database will be distributed, encouraging rapid, open dissemination of results to...
