Amazon DynamoDB is a next-gen nosql (Not only SQL), key-value and document database that delivers single-digit millisecond performance at any scale. As more complex web-based applications adopt DynamoDB, it is imperative to develop sound design strategies for DynamoDB schemas. Large-scale web-based applications often exhibit conflicting requirements. Hence, the research problem is to design the DynamoDB schemas of a given application with conflicting requirements such that the database must satisfy certain predetermined performance goals. In the era of relational databases, normal forms were developed to guide the schema design process. Past knowledge and experiences, we believe, are also applicable to DynamoDB schema design. Specifically, based upon Nested Normal Form and XML databases, this paper demonstrates the feasibility of a design strategy on DynamoDB schemas, particularly with the access patterns of the data in mind. Simulation further substantiates the feasibility of our approach.

Due to the popularity of big data applications, such as social networking, e-commerce, etc., companies need to quickly access huge amounts of data. Under such conditions, a relational database (RDB) cannot meet the demand, and more and more companies decide to switch to nosql database to maintain competitiveness. It's necessary to convert data from an RDB to a nosql database for the companies that have a lot of operation data in an RDB. Therefore, this paper proposes an algorithm to explore how to convert the schema of RDB into the ones of Wide Column Store DB (WCSDB), and how to import actual data from an RDB into a WCSDB.

Technologies such as cloud computing and big data management, have lately made significant progress creating an urgent need for specific databases that can safely store extensive data along with high availability. Specifically, a growing number of companies have adopted various types of non-relational databases, commonly referred to as nosql databases. These databases provide a robust mechanism for the storage and retrieval of large amounts of data without using a predefined schema. nosql platforms are superior to RDBMS, especially in cases when we are dealing with big data and parallel processing, and in particular, when there is no need to use relational modeling. Sensitive data is stored daily in nosql databases, making the privacy problem more serious while raising essential security issues. In our paper, security and privacy issues when dealing with nosql databases are introduced and in following, security mechanisms and privacy solutions are thoroughly examined.

With the arrival of cloud computing and big data, enterprise application systems are supported by massive data storing in cloud data centers (CDCs), in which the popular open-source nosql databases (Cassandra, HBase, MongoDB) are utilized to cope with high concurrency, high availability, and high scalability. There are still two challenging issues: (1) When the consistency level and replica number is specified, selecting the appropriate nodes for data replicas to reduce the communication latency is necessary. (2) A tradeoff between reliability and synchronization time should be discussed in CDCs. In this paper, a cross-area node selection algorithm (CANSA) is proposed to minimize the communication latency, then a new method to adjust reliability in the data center is designed. Numerical results in the Cassandra cluster of CDCs demonstrate that the CANSA provides excellent consensus ratio, synchronization, and latency.

Every year, the amount of data produced in health-care institutions in the field of medical imaging is increasing. The easy accessibility to digital modalities and the proliferation of diagnosis centers working in network of services, creates the need for very large repositories of data. Moreover, the institutions have redundant storage across the network and load balancing mechanism to improve access performance. nosql databases provide horizontal scalability which allows the system to grow easily and effortlessly. Document databases are particularly suitable to store the DICOM metadata and the JSON format is already supported by the standard. This paper, we discuss the use of document database model in the medical imaging field, trying to focus on both clinical and research environments. Moreover, we focused on the proposal of an architecture based on MongoDB to distribute the load between multiple nodes. The proposal was integrated with an open-source PACS and validated by simulating multiple operations over data distributed across multiple virtual locations, and the results are promising.

In modern days, database systems usage keep increasing where they have become an essential part of our life in storing records. As technology advances, databases receive updates or new improved methods that, alongside it, risks emerge and increase if left unresolved or unaware of such ongoing risks. Such risks would lead to data availability, integrity, and confidentiality to be broken and leaked out into the hands of cybercriminals. This paper aims to show two types of databases, analyze their security, and propose a solution to securing and maintaining the availability, integrity, and confidentiality of the data stored in the database.

Almost every web application uses a database for storing data. Storing and retrieving data causes a delay between request to the system and its response. This has an impact on user-experience. The market offers many types of databases and each is more suitable for different types of applications. The main difference is in data-structures which are used for data storing. Data-structures directly influence the performance of the database system and all dependent systems. In this paper, an overview and brief comparison of four types of nosql databases has been made. Next, benchmark comparing performance of MongoDb and MySQL in different situation are discussed. Benchmarks are focused on operations such as inserting, updating, and deleting data with transactions and without transactions. The added value of the benchmarks is evaluated in terms of cost of indexed fields in the abovementioned situations.

Database technology is one of the key elements in every internet-based system. As technology develops and the need for fast and large data exchange arises, a type of nosql or unstructured database emerges. SQL and relational databases have table forms, while nosql has a format of document-oriented stores. Integration issue came as a challenge when the two different databases were used on the same software. The challenge is increasingly complicated when the database used becomes the resource of online websites. In this study, we present a case which based on 2 online e-Commerce furniture websites that. These both online websites will merge their product data into 1 new database. This research combines two different databases using Web services to retrieve data in each database and a synchronization system for the process of checking and storing data into a new database. All merging components are stored on cloud storage services. Every batching process in the synchronization system is done online and automatically uses Cron. This research provides the results of data integration testing on web services and measurement of the synchronization system execution time. After testing 2 web services used, all passed the data integration test. Then measurements are made on the synchronization system by looking at the displayed execution time. The results of measurements using 100 to 1000 data and different conditions, the execution time obtained from 4 to 5 seconds for each data in the measurement increases to 500 data. The results of this study indicate that the integration of data from 2 different databases using web services and synchronization systems is tolerable and suitable for the amount of data under 10000 data with the condition of the database already filled.

The systems helping us nowadays in some sectors, including health service, transportation, medicine, and many others, have one common thing: data. The data in the mentioned sectors help with the support of decision making, to manage systems, and to prevent dangerous situations. To the increasing amount of the data, a growing demand was related. In the current modern era, the data has become a commodity, and the data are traded like goods in many cases The systems, working with the massive amount of the data, do not only with values already in the system but also with the system's data in real-time. So, they influence many evaluation systems, respectively, they modify various statistics. The real data play a crucial part during transformation processes and the mutual affecting of the data. This article will create a synchronization barrier that will be used to influence the data during the data transformation from a relational database to a nonrelational database. The purpose of this barrier is to reduce the time needed for a data change from source database to target database and, by this, to reduce the number of operations that would be required to do after finishing the process just with incoming values.

Currently, the development of data has increased rapidly, Solutions are needed to be able to manage data efficiently, one that can be offered is to utilize the database. The biggest decision in selecting a database is to select between SQL or nosql. MySQL is a database that uses SQL as a query language, consists of tables that store data in the form of columns and rows, then the new format database nosql, appeared, it is suitable for handling large amounts of data in a variety of formats. Neo4j is one of nosql that is widely used, it is a graph database which provides an easy way to visualize data by storing data in the form of nodes that are connected by edges. In this paper, we compared the performance of MySQL and Neo4j databases in terms of memory usage and execution time, also we presented the flexibility of the databases using P. The results show that MySQL has a faster execution time than Neo4j, although, both these databases have the same time complexity. It is also known that Neo4j has a higher memory usage than MySQL. But Neo4j has better flexibility than MySQL.
