With the advent of big data phenomenon in the world of data and its related technologies, the developments on the NoSQL databases are highly regarded. It has been claimed that these databases outperform their SQL counterparts. The aim of this study is to investigate the claim by evaluating the document-oriented MongoDB database with SQL in terms of the performance of common aggregated and non-aggregate...
Cloud SQL Server is a relational database system designed to scale-out to cloud computing workloads. It uses Microsoft SQL Server as its core. To scale out, it uses a partitioned database on a shared-nothing system architecture. Transactions are constrained to execute on one partition, to avoid the need for two-phase commit. The database is replicated for high availability using a custom primary-copy...
A wide range of database applications manage time-varying information. Existing database technology currently provides little support for managing such data. In this paper, based on principles and ideas of a temporal processing component called TempDB, we deeply insight into extensions to non-temporal RDBMS, and then use RMI technology to develop a distributed temporal data management platform, the...
In order to realize the modernization of mine enterprises, enforcing “Digital Mine” construction is necessary. And the key of enforcing “Digital Mine” construction is to solve the effective storage and management of mine spatial data. The paper firstly shows the characteristic features of mine spatial data. Then it discusses the method of the storage and management of mine spatial data on the basis...
At present, as a new trend of the telecommunication industry, mobile application requires refine the technique of data management continuously, therefore, mobile database has been come into being. The thesis mainly focused on the introduction of mobile database and the characteristics of data management, especially analyzed the architecture and functions of the SQL Server CE. On this basis, according...
Developing, maintaining and accessing complex information repositories are some of the main concerns of todaypsilas information society. In huge distributed systems, guaranteeing good performances and data integrity is a real challenge when using standard relational databases. This paper presents a database concept methodology that addresses these concerns under the form of an ldquoRDBMS independentrdquo...
The normalized PDM (physical data model) affects the performance of database. In this paper, the normalization and database data model design of RDBMS were discussed in brief. The deep analyses of the de-normalization principles and methods for design optimization of a physical data model of a test bank based on SQL Server were used to improve the performance of database.
