Introduction to NoSQL
For storing the data in organized manner we use the traditional relational databases and in these databases the information is stored in the form tables. NoSQL is an abbreviation or a short form for ‘Not only SQL’. Carlo Strozzi in 1998 for the first time used this name to refer their open source relational database, which didn’t exposed its SQL interface. As this was different from the relational databases so on later stage he suggested to name it NoRel (No Relational) instead of NoSQL (Not only SQL). As the name indicates, in NoSQL we use additional methods to store data. NoSQL as compared to the traditional relational databases use different data structures like Key-value, document-oriented, Column oriented or graph oriented. In comparison to traditional databases these data structures offer faster operations in NoSQL. The use of NoSQL is dependent on what problem we aim to solve with it.
The sole purpose of existence of such databases is approach to simplicity in design, better horizontal scaling and greater control over the availability of data. See Figure 3 for scaling. The use of other means of storing data and different access mechanism, provide faster access to data based on the problem which the organization aims and this is also the reason NoSQL databases is famous for use in big-data and real-time web applications.
Previously NoSQL databases lack the ACID (Atomicity, Consistency, Isolation, and Durability) which ensures that transactions are made in reliably. Whereas the new era NoSQL databases have made this a part of their system, some of such databases include FairCom’s ctree-ACE, Google’s Spanner and FoundationDB.
Types of NoSQL databases:

Summary:
CouchDB is an open source database which was written in Erlang, which has the ability to synchronize the data between offline and online devices by using replication. It uses the JavaScript as a query language and makes use of Futon to provide the administrative controls. It has some of the very useful features like ACID semantics that were not available in other NoSQL databases. Has the ease of use in different operations. It keeps the data in form of documents as opposed to the traditional databases which use tables. Each document is identified by its unique id. CouchDB supports eventual consistency, REST API, distributed architecture and MapReduce.
What technology can do for a company is important. A database takes information from one location and sends it to another location. Amazon’s database is the backbone to the company because Amazon is an e-commerce base company. Amazon runs off of a Linux- based database. As of 2...
...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.
INTRODUCTION: With cloud computing, Amazon has enabled the usage of internet and central remote servers to maintain data and applications and created an environment where connectivity and availability is unobtrusive and prevalent. Amazon offers two options for hosting applications and databases. Amazon EC2 with Elastic Block Storage allows one to run a MySQL database server on Elastic Compute Cloud, an Infrastructure-as-a-Service provider, with Elastic Block Storage (EBS). Meanwhile, another option called Amazon’s Relational Database Services (RDS) is a scalable relational database in the cloud with high availability.
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.
This paper was written to show the similarities and differences in five different databases. It compared Access, MySQL, SQL Server, DB2, and Oracle in six different areas. It found many similarities in functionality, but large diversity in pricing.
Data warehousing is a difficult system and has to have the capability deliver quality data. An operational database is one which is used by organizations to run its day to day database activities. They are designed to handle rapid transaction processes with systematically updates. Velocity is important to operational databases. They are most commonly operated by office staff, and are on the order of megabytes of data to gigabytes. Database consistency checks and constraints are rigidly enforced. They contain the latest technology necessary to operate organizational functions.
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
For those who, until now, had been carrying around a mobile phone and PDA, this combines the two into one unit, without losing any of the capability of either format.
The key to Amazon’s strategy is the IT infrastructure’s ability to deal with more than a million requests at a consistent, error-free rate (Demir, 2017, p.12). Not to mention, Amazon’s Web Services makes up for about 10 percent of their total revenue. The first big play for Amazon’s Web Services was the launch of DynamoDB which sent customer data to multiple databases creating a strong collaboration system. By testing this system for long periods of time, Amazon analyzed the faults within it. However, with this jewel, engineers expanded new features and algorithms within the system. In order to get the design up to expectations, engineers improved the mastery of independent codes. Throughout the complexity of Amazon’s expansions, AWS has played a pivotal role in the Systems Developmental Life Cycle. “As an example of this growth, in 2006, AWS launched S3, its Simple Storage Service…Less than a year later it had grown to two trillion objects and was regularly handling 1.1 million requests per second” (Newcombe, 2015, p. 66). Developing such systems has given Amazon the ability to establish unforeseeable innovation which continues to astonish the entire world. As everything has become newer and improved through technology, Amazon implements this into each and every
For one’s spiritual development to be in a positive balanced state it requires the aql and nafs to be synchronised and to override its negative counterparts. Aql (intellect & reason) and nafs (ego) are just two parts of an interconnection of faculties within human beings. Aql is not only the operation of thinking, but has faculties within itself that are vital to comprehend. The aql differentiates man from animal, it is where knowledge is absorbed and its attainment produces a noble man. The aql is the medium that needs to be disciplined for only its positive gain for its spiritual journey, therefore reflecting and remembering God and His creation and Revelation. The nafs is a metaphysical system abundant in negative attributes, but a variable entity within us to allow us to appreciate the positivity when guided in the right path in one’s spiritual journey. Spiritual cleansing (tazikyah al-nafs) can be practiced for one to reach such a positive balanced state for the nafs. Therefore synchronising the aql and nafs towards positivity, will result in attaining a balanced spiritual state.

Databases are becoming as common in the workplace as the stapler. Businesses use databases to keep track of payroll, vacations, inventory, and a multitude of other taske of which are to vast to mention here. Basically businesses use databases anytime a large amount of data must be stored in such a manor that it can easily be searched, categorized and recalled in different means that can be easily read and understood by the end user. Databases are used extensively where I work. In fact, since Hyperion Solutions is a database and financial intelligence software developing company we produce one. To keep the material within scope I shall narrow the use of databases down to what we use just in the Orlando office of Hyperion Solutions alone.
In simple terms, it's just a storage located remotely which you can access anywhere. It's like storing your files online and accessing it anywhere while using your laptop, mobile device or another PC.
The Database Management System (DBMS) is software that enables the users to define, create, maintain and control the access to the database. It is a software that interact with the user’s applications programs and it database. Meanwhile, information retrieval system is a system that involved the activity that the systems obtain the information. The obtaining information action need the information from it resources.
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.
