Since the SQL language appeared in mid 1970s, it has been leading the relational database industry for many years. With the modern era of databases not everyone sees the advantages of using relational databases. NoSQL, was first developed in the twenty first century (MongoDB, para 19) to address the issues that the SQL language could not handle. NoSQL cannot handle pure relational database models, it can use any of five different kinds of models, including relational to solve problems. With the variety of models, designers are wondering if there is a future for the strictly relational language SQL, and it’s other disadvantages compared to that of NoSQL.
Databases
NoSQL is seeing a large surge in popularity in recent years. Compared to the

With the advancement in database systems and software, Eric Brewer in his new article that: “The modern CAP goal should be to maximize combinations of consistency and availability that make sense for the specific application.Such an approach incorporates plans for operation during a partition and for recovery afterward, thus helping designers think about CAP beyond its historically perceived limitations.” (Brewer, 2012)
Meaning that with the great advancement in technology, the creation of NoSQL, designers are able to optimize their database systems to get achieve the best results from the CAP theorem as possible.
How it Works
With the modernization of NoSQL and it’s adaptation to fix problems with old relational databases, it is able to store data in many different ways. There are five main database types for NoSQL: relational, key-value, document databases, column family stores and graph databases. Each of the four are unique in their own way and thus different systems and companies support different database types. A key-value database is described by Pramod Sadalage, in his article on

In a journal written by Alexandru Boicea, Florin Radulescu and Laura Ioana Agapin, they cover the comparison of both a system using the SQL language and a system of the NoSQL language. The two management systems in place are Oracle, a system built off of SQL and MongoDB a system off of NoSQL. The authors are quick to say the main key features including that of the flexibility the MongoDB system has compared to Oracle. Oracle has defined schemas and do not provide the designer a lot of flexibility to quickly add new data. Oracle follows a strict relational model where as MongoDB does not. With MongoDB not following the traditional relational database model, allows the system to scale larger and become
...now use. Majority of the world’s data is unstructured. Big data technology lets us analyze and bring together data of different types. A common theme in the data is that it is diverse. It doesn’t fall into a relational structure. Different browsers send different data; users withhold information, different forms of software versions, or vendors to communicate with you. There will be many errors and inconsistency if the process involves people. Big data is used to take unstructed data and extract ordered meaning. This is for consumption by users or it is structured input into an application.
The first database systems were based on the network and hierarchical models. A database can be defined as a collection of non-redundant data which can be shared by different application systems. A database implies separation of physical storage from use of the data by an application program to achieve program/data independence. Using a database system, the user or programmer or application specialist need not know the details of how the data are stored and such details are usually "transparent" to the user. .
As defined by Kroenke Database is an integrated, self-describing collection of related data. Data is stored in a uniform way, typically all in one place- for example, a single physical computer. A database maintains a description of the data it contains and the data has some relationship to other data in the databa...
NoSQL are called non-relational databases, which is not created by any software companies. The examples for NoSQL are Dynamo created by Amazon, Bigtable created by Google, and Cassandra created by Facebook. NoSQL supports...
In the world of database technology, there are two main types of databases: SQL and NoSQL—or, relational databases and non-relational databases. The difference speaks to how they’re built, the type of information they store, and how they store it. Relational databases are structured, like phone books that store phone numbers and addresses.
In 1977, Larry Ellison, Bob Miner, and Ed Oates founded System Development Laboratories. After being inspired by a research paper written in 1970 by an IBM researcher titled “A Relational Model of Data for Large Shared Data Banks” they decided to build a new type of database called a relational database system. The original project on the relational database system was for the government (Central Intelligence Agency) and was dubbed ‘Oracle.’ They thought this would be appropriate because the meaning of Oracle is source of wisdom.
Apache Hadoop is one of the solutions; it is an open-source software framework for storage and large scale processing of data-sets on clusters of commodity hardware [3]. Also, Apache Hadoop is a scalable fault-tolerant distributed system for data storage and processing. The core of Hadoop has ...
For this coursework two kinds of data models can be used. The object oriented data model, Object Oriented Database Management System(OODBMS), or the relational data model, Relational Database Management System(RDBMS). The differences between these two models and the data model to be used are described in this chapter.
Almost all commercial database systems available today are designed to provide a high level of performance to its users. Nonetheless, Database Performance Tuning for large volumes of data is an arduous task. Even minor changes can bring about a substantial impact (positive or negative) on the performance of the system (KOCH, 2014).

RDBMS remains for Relational Database Management System. RDBMS information is organized in database tables, fields, and records. Each RDBMS table comprises of database table columns. Every database table line comprises of one or more database table fields. RDBMS store the information into the accumulation of tables, which may be connected by basic fields (database table sections). RDBMS additionally give social administrators to control the information put away into the database tables. Most RDBMS use SQL as database query language
Oracle's relational databases represent a new and exciting database technology and philosophy on campus. As the Oracle development projects continue to impact on University applications, more and more users will realize the power and capabilities of relational database technology.
NoSQL are designed to expand transparently to take advantages of new nodes and they are built using low cost hardware, so cost shouldn’t be a problem. Big Data In today’s world, the transactions are so frequent that the data generated out of these transactions is huge. It is very difficult to store these huge transactional data in the traditional database systems. NoSQL with its elastic scaling feature, it is possible to increase the size of the database to store huge amount of transactional data. All the challenges involved in processing these huge transactional data can be overcome with NoSQL database systems. No DBA required NoSQL database systems can handle many of the things on its own. Dedicated database administrators are not required to handle day to day database operations. Since these systems have simpler data models, automated repair etc., No administrator is necessary to handle these things. Economics Traditional databases costs more money. The amount of space that you get on buying traditional database systems is less when compared to the NoSQL database system. In other words, cost per gigabyte per second or transaction per second is many times less when compared to traditional database management system. Flexible data model NoSQL database systems have flexible data models, unlike traditional relational database management systems. If any changes to the data model in traditional database systems, then it may bring down whole database system or the functions might not work as expected. But this is not the case with NoSQL database system. NoSQL has far more relaxed data model which allows the user to add a new column to store data without any much fuss. NoSQL key value stores and document the database virtually in a data
Databases have been in use since the earliest days of electronic computing, but the vast majority of these were custom programs written to access custom databases. Unlike modern systems which can be applied to widely different databases and needs, these systems were tightly linked to the database in order to gain speed at the price of flexibility.
In our world, people rely heavily on the power of technology every day. Kids are learning how to operate an iPad before they can even say their first word. School assignments have become virtual, making it possible to do anywhere in the world. We can receive information from across the world in less than a second with the touch of a button. Technology is a big part of our lives, and without it life just becomes a lot harder. Just like our phones have such an importance to us in our daily lives, database management systems are the same for businesses. Without this important software, it would be almost impossible for companies to complete simple daily tasks with such ease.
