Currently, most health care systems used among divisions in medical centers still adopt the Excel file format for a variety of scales statistics, such as the clinical self-care ability scale for Functional Independence Measure. Although people can further analyze Excel files using other statistical analysis software, such as SAS, SPSS, and STATA, they cannot effectively share the archived data in Excel among divisions. We propose to do format conversion on these data and store them in a database. As the collection of Excel files cannot be shared with ease, we plan to use HBase, a non-relational database, to further integrate data. The purpose of this paper is to construct complete import tools and solutions based on HBase to facilitate easy access of data in HBase. Besides, a visual interface is also used to manage HBase to implement user friendly client connection tools for the HBase database.

With the development of Internet technology and Cloud Computing, more and more applications have to be confronted with the challenges of big data. nosql database is fit to the management of big data because of the characteristics of high scalability, high availability and high fault-tolerance. And it is one of the technologies of the management of big data. We will improve the performance of massive data processing of nosql database through the large scale data parallel data processing and data localize of computing. So how to allocate the data will be a big challenge of nosql database. In this paper we will propose a data allocation strategy based on the node's load, which can adjust the data allocation strategy by the execute status of the system. And it can keep the balance of data allocation by a small cost. At last we will use some experiments to verify the effectiveness of the strategy which is proposed in this paper. The experiments show that it can improve the system's performance than other allocation strategy.

This paper introduces the combination of nosql database HBase and enterprise search platform Solr so as to tackle the problem of the secondary indexing function and do fast query. An intelligent adaptation of adaptive network-based fuzzy inference system (ANFIS) along with particle swarm optimization (PSO) has been employed off-line to tune seamless handoff and network traffic flow. Finally, the assessment using performance index has been done for several competitive benchmark databases and the proposed one, verifying the effectiveness and efficiency of the proposed approach.

Data collection from distributed cloud storage through SaaS application requires efficient execution of the overall process. This type of cloud computing mechanism can be furnished through shared resources, improved service levels and minimal management effort. Data retrieval from cloud storage by different users through shared resources environment may blend data from different data requests in a single place. Here lies the need of efficient data retrieval strategy among different users that will help in secure data retrieval. When sensitive information is transmitted over the Internet there is high chance of information leakage. So, to prevent security attack like interference attack during query execution becomes a big challenge. This work explores a novel data retrieval strategy in extremely robust and linearly scalable high performance nosql database like Cassandra and presents a brief security analysis while retrieving stored data in shared environment.

Popularization of big data makes the enterprise need to store more and more data. The enterprise's database must access data as fast as possible, but RDB has the speed limitation due to the join operation. Many enterprises have changed to use nosql database which can meet the requirement of fast data access. However, there are more than hundreds of nosql databases. It is important to select a suitable nosql database for a certain enterprise because this decision will affect the performance of the enterprise operations. In this paper, 15 categories of nosql databases will be analysed to find out the characteristics of every category. Some principles are proposed to choose an appropriate nosql database for different types of enterprises.
Column Family has been used in nosql database, and we have to think over how to divide the Column Family in the designing of nosql database. But the dividing of column family is similar to the vertical partitioning in...

Recently, there has been growing interest in monitoring the road traffic data. Most of the work focused on real-time traffic data. In this paper, we propose an ExTrac system which extracts trend of traffic congestions from historical traffic data and answers the queries about the trends. In ExTrac system, we first convert the historical traffic data into traffic patterns then summarize it by applying MapReduce style algorithms. These traffic patterns are store into a nosql database. Our implementation demonstrates the feasibility of ExTrac for querying traffic information and generating the result.
