Relational Database Management Systems are probably the ones that we are most familiar with in 21st century computer science. Relational databases store

An RDBMS is a software program that allows users to enter, manipulate, and retrieve data.

Relational data is when you can put data in a computer one time and it grows

Most database ensure that they follow the ACID (Atomicity, Consistency, Isolation, Durability) properties to ensure the transactions are reliable. The studies show that stores that guarantee ACID property generally have poor availability. As a result, Dynamo focusses on application that have weaker consistency.

One advantage to using relational databases include ease of use due to query languages, and the ease of altering the structure due to data independence. In addition, there are no predefined set of relationships between data records in the relational

An enterprise data model presents an abstraction of a more complicated real-world event or object. Generally, a data is graphical simple representation, of an interconnected real organization’s data structures. The main function of the data model is to help in understanding the complexities of a particular organization. A data model within a database environment brings out the data structures, their transformations, constraints, relations, and characteristics, thus providing a blueprint of

In 2000 Deborah Rowe an article that centered on business trends pushing database management systems to greater growth. Rowe focuses on the data warehousing concept that has proved to meet a large majority of business needs in terms of information management. The focus of the article is to explain how progress is pushing for better and better systems for managing data.

Some of the challenges faced by relational databases were the mismatch that resulted when transforming graphs into tables. On the other hand, when a database was needed only for simples tasks like logging, the relational database had too much more than what was required. Web applications have many different types of attributes which does not fit easily into a relational database, which makes it a burden to handle. For example, videos, text and source code are different types of attributes from the web, which have to be stored in various tables if relational databases are used, because of its strict schema. Qualities like these, make RDBMS, a not-so-wise choice to handle blogs and other web applications. The massive data that has to be taken care of in web applications complicates data handling for famous webpages like Amazon, Google and Facebook. Factors like trillions and trillions of read and write requests which needs to be responded with minimal or no latency, leads these organizations to maintain their own hardware in clusters of thousands. The “One solution for all” is

In Nowadays, there are two major of database management systems which are use to deal with data, the first one called Relational Database Management System (RDBMS) which is the traditional relational databases, it deals with structured data and have been popular since decades since 1970, while the second one called Not only Structure Query Language databases (NoSQL), they are dealing with semi-structured and unstructured data; the NoSQL types are gaining their popularity with the development of the internet and the social media since April 2009. NoSQL are intending to override the cons of RDBMs, such as fixed schemas, JOIN operations and handling the scalability problems. In this paper we will review one of the graph database (Neo4j), which the graph database is part of the emerging technology that is called NoSQL and compared it with one of the traditional relational database (MySQL). MySQL, it is being another name for Relational Databases and it has been used for a long period time until now. However, with the emergence of Big Data there was clearly a need for more flexible databases. Facebook 's Graph Search using Neo4j, a graph database, is an application which clearly displays how relationships need to be modeled in a more efficient and sophisticated manner than using conventional relational models. In this paper, we will make a compare between MySQL and Neo4j based on the features like ACID, replication, availability and the language that is used in both of

\item A visual query language is designed based on the existing visual metaphor of genome browsers. Its semantics via an algebra and translation to SQL3 are provided. It incorporates a type system for genomics data with a set of topological and logical operations. New operations can be designed using function composition based on the data model. The operations have equivalent translation to SQL3. The algebra provides the semantics for the visual query language and facilitate a visual query language implementation based on this algebra. A database architecture using a visual query language based on this algebra is proposed.

* Scalability. Server databases are able to gracefully handle a rapidly expanding amount of users and/or data.

1.) The RDBMS is a program or a group of programs that helps to maintain a relational database. This software gives the ability to the user to convert the user’s requests for data into a logical format with the answers to that request. It also contains a data dictionary to make available more security, easier access, and data integrity.

The modern RDBMS advancements are not capable of supporting unstructured information with ideal space necessity. The plan winds up plainly mind-boggling and is henceforth troublesome for designers. The requirement for unstructured information administration is so annoying with conventional RDBMS arrangements (Big data in financial services industry: Market trends, challenges, and prospects 2013 - 2018). Moreover, RDBMS turns out to be an exorbitant answer for creating light-footed web applications with direct information investigation necessities. NoSQL is developing as a proficient possibility in this situation, which connects the issues related with RDBMS innovation. The market development can credit to creative dispatches of NoSQL arrangements, and collective endeavors by NoSQL sellers and clients. The endeavors of organizations, to enhance their market offerings, are creating the request of NoSQL, as a back-end bolster (Big data in financial services industry: Market trends, challenges, and prospects 2013 - 2018). The emergence of agile software development is creating the demand for NoSQL (Big data in financial services industry: Market trends, challenges, and prospects 2013 - 2018). They offer users much more avenues to accept data in many different forms. NoSQL is adaptable as SQL but offers many more uses that can apply to many organizations.

Introduction: eXtensible Markup Language is used mainly in most of the organizations for e-commerce and online applications. Indeed, XML has become the standard for representing, exchanging the data among the various applications on the internet. Moreover, XML schema is used for representing the XML document structure where XML data is associated with the XML schema. Furthermore, data warehouse provides tools which business use the data for making the important decisions. Correspondingly, data is stored in the fact table and multidimensional tables. Mainly, the table association between them are generally represented with the three data warehouse schemas like a) star schema b) fact constellation schema c) snowflake schema. Simultaneously, the use of the internet is increasing day by day and by first integrating the data and secondly converting the data into XML schema from the schema graph to the various data schemas. At first, schema graph is taken as the model for the conversion of the data that is extracted from the XML schema and the data is transformed into the various schema. Consequently, the data warehouse schema is constructed with these fact tables, dimension tables and the relation existing between the graph and tables.

Given the advantages of using RDF (Lassila and Swick, 1999), (Susmitha and Thammi Reddy, 2011). According to Zhou (Zhou et al., 2010), there are three kinds of RDF data storage formats, one is XML / RDF file format, the second one is a special XML / RDF database and the third one is a traditional relational database. If small amounts of data is considered then it is preferable to go with XML/RDF file storage, But if large amounts of data are considered where scalability, data integrity, query efficiency etc; are important, then it is preferable to go with XML/RDF database or relational database for storing RDF data (Zhou et al., 2010). In this paper, as SodhanaRef is experimental and
