In today's open market, e-commerce has developed its strategy to process various business applications. There applications are developed with the platforms like Magento, Zen Cart, Prestashop, Spree etc., to run a successful online store. These are also used for customer e-commerce apps and require a scalable database for storing the data. The NoSQL database provides an efficient storage access and...
With the proliferation of unstructured data, and the inability of relational databases to handle such data in an efficient manner, non-relational databases have gained importance over the last decade. This paper provides a brief description of non-relational database characteristics. It explains the important features of MongoDB and Oracle NoSQL databases. It provides guidance to the decision makers...
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...
NoSQL databases are becoming increasingly popular as more developers seek new ways for storing information. The popularity of these databases has risen due to their flexibility and scalability needed in domains like Big Data and Cloud Computing. This paper examines asynchronous replication, one of the key features for a scalable and flexible system. Three of the most popular Document-Oriented Databases,...
This paper describes the Linked Data initiative in meteorological environment. MetOcean data are meteorological and oceanographic datasets that provide information to meteorological industries, petroleum industries as well as research institutes. The MetOcean has a myriad of data and scattered along the globe which lack Linked Data or Semantic Web capabilities. Linked Data is a concept of publishing...
The class of distributed Real-time Online Interactive Applications (ROIA) includes such important applications as Massively Multiplayer Online Games (MMOGs), as well as interactive e-Learning and simulation systems. These applications usually work in a persistent environment (also called world) which continues to exist and evolve also while the user is offline and away from the application. The challenge...
With the growing of the Internet, lots of heterogeneous relational databases are built in distributed environment. Data exchange between these databases absorbs more attention of researchers and engineers nowadays than ever. As a well-formed makeup language, XML is suitable to store and transfer information. Therefore we investigate the data exchange method via XML in this paper. We analyze mapping...
Nowadays, more and more data are created every day. To process time-series data in real time, many organizations are looking beyond the traditional data warehouse solutions and into emerging big-data technologies such as open source Map-Reduce frameworks or no-SQL databases. In this project, we develop an application which follows a keyword over multiple social media platforms (e.g. Twitter, Facebook),...
Motivated by requirements of Web 2.0 applications, a plethora of non-relational databases raised in recent years. Since it is very difficult to choose a suitable database for a specific use case, this paper evaluates the underlying techniques of NoSQL databases considering their applicability for certain requirements. These systems are compared by their data models, query possibilities, concurrency...
In this paper, we focus on the storage schema, encoding/decoding and data compression algorithm of ArcSDE vector feature models in Relation Database Management System (RDBMS). Further, Based on ODBC database accessing techniques, we discuss systematically and implement method for direct access to the ArcSDE vector feature data which is stored in SQL Server 2000 RDBMS with the C++ programming language...
The photogrammetry database mostly stores and manages the data of digital map, such as the data of digital elevation model, digital line graphic, digital orthophoto map and digital raster graphic in this area. In this paper, The design and implementation method for Photogrammetry System based on commercial database management system (such as ORACLE, SQL Server) is discussed. In addition The use of...
Spatial database information stores with vector form in Geographic information system based on Web (WebGIS), relational database information stores with two dimension form, they are not to convert for each other directly, and to lead to universal is weak, availability of spatial data is low. In order to solve this problem, this paper proposes a way which uses XML as the middle carrier to achieve data...
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...
Take the relational database as the data model, in analyzes several kinds already in the data encryption technology base which has, studies the database data to save and to establish the corresponding database confirmation mechanism by the scrambled text way. Proposes based on the connection sub-key production algorithm as well as based on the user information key management technology and the field...
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...
In account of the heterogeneous data existed in the e-commerce, the solution of heterogeneous database data exchange middleware based on XML is brought up. With the beginning of heterogeneous data integration, this paper combined with the examples of e-commerce platform construction, realized the transformation and integration of the relational data to XML data, which provided the underlying support...
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.
