It is the data that is very large and complex with an enormous speed of generation.<\/p>\n<p>The act of collecting, storing, and utilizing data for analysis and drawing insights has been in practice for quite a long time. But the term Big Data came into existence in the late 2000s.<\/p>\n<p>Big data depend on three V\u2019s which are as follows:<\/p>\n<ul>\n<li>Volume<\/li>\n<li>Velocity<\/li>\n<li>Variety<\/li>\n<\/ul>\n<p>The importance of data or big data lies in the fact that what you can do with it and not the amount of data you have.<\/p>\n<h3>What is SQL?<\/h3>\n<p>SQL, which goes by the full form &#8211; Structured Query Language is a programming language.<\/p>\n<p>It is a query language used to deal with relational database operations and queries.<\/p>\n<p>It involves manipulating or updating a database or creating a new database. Major operations on a database are famous as CRUD operations i.e., Create, Read, Update and Delete and are a widely used database in the technological world.<\/p>\n<p>The database should be able to store the large volumes of data being produced today.<\/p>\n<p>SQL is a powerful tool for someone who deals with data on a day-to-day basis. SQL can insert data into a database.<\/p>\n<p>It can search for some data in the database and also it supports updating and deletion of data stored in the database.<\/p>\n<h3>What is NoSQL?<\/h3>\n<p>A NoSQL database is invested into the simplicity of use and control over the availability.<\/p>\n<p>The data structures which are the core of NoSQL are far away in similarities when compared to the RDBMS counterparts of it.<\/p>\n<p>The compatibility of a given NoSQL database in a situation depends on the problem which we need to solve.<\/p>\n<p>Data structures used by NoSQL are flexible when compared to the other available RDBMS resources.<\/p>\n<p>NoSQL stores are reliable and scalable with all the available systems.<\/p>\n<p>Some of the drawbacks include the use of low-level query languages and the lack of proper user interfaces. NoSQL databases lack proper ACID properties.<\/p>\n<h3>SQL vs NoSQL<\/h3>\n<p>The comparison between SQL and NoSQL is as follows:<\/p>\n<table style=\"height: 897px;\" width=\"949\">\n<tbody>\n<tr>\n<td><b>Sr.No<\/b><\/td>\n<td><b>Point of comparison<\/b><\/td>\n<td><b>SQL<\/b><\/td>\n<td><b>NoSQL<\/b><\/td>\n<\/tr>\n<tr>\n<td><b>1<\/b><\/td>\n<td><b>Interaction\u00a0<\/b><\/td>\n<td><span style=\"font-weight: 400;\">SQL is a highly interactive language and deals with almost all inputs provided by the user.<\/span><\/td>\n<td><span style=\"font-weight: 400;\">NoSQL lags in interaction as it demands the user to be very specific in what they need as the output.<\/span><\/td>\n<\/tr>\n<tr>\n<td><b>2<\/b><\/td>\n<td><b>Standardization<\/b><\/td>\n<td><span style=\"font-weight: 400;\">SQL is universally accepted as a standard database.<\/span><\/td>\n<td><span style=\"font-weight: 400;\">NoSQL is not a standard database management system.<\/span><\/td>\n<\/tr>\n<tr>\n<td><b>3<\/b><\/td>\n<td><b>Scalability<\/b><\/td>\n<td><span style=\"font-weight: 400;\">SQL systems are scalable and fault tolerable systems, but the achievement of large scale deployment of the system is not feasible.<\/span><\/td>\n<td><span style=\"font-weight: 400;\">NoSQL had a focus on distribution and scalability since the start. Thus, is very effective when it comes to the scalability of even the huge systems.<\/span><\/td>\n<\/tr>\n<tr>\n<td><b>4<\/b><\/td>\n<td><b>JSON support<\/b><\/td>\n<td><span style=\"font-weight: 400;\">SQL is rich in providing support for various data types.<\/span><\/td>\n<td><span style=\"font-weight: 400;\">NoSQL supports and deals with unstructured data.<\/span><\/td>\n<\/tr>\n<tr>\n<td><b>5<\/b><\/td>\n<td><b>Flexibility<\/b><\/td>\n<td><span style=\"font-weight: 400;\">SQL can only deal with the data of predefined type.<\/span><\/td>\n<td><span style=\"font-weight: 400;\">NoSQL has the capability to handle any input data provided.<\/span><\/td>\n<\/tr>\n<tr>\n<td><b>6<\/b><\/td>\n<td><b>Cost<\/b><\/td>\n<td><span style=\"font-weight: 400;\">SQL systems end being too costly.<\/span><\/td>\n<td><span style=\"font-weight: 400;\">NoSQL systems are very cost-efficient.<\/span><\/td>\n<\/tr>\n<tr>\n<td><b>7<\/b><\/td>\n<td><b>Data Integrity<\/b><\/td>\n<td><span style=\"font-weight: 400;\">SQL databases work on the ACID properties hence always provide data integrity.<\/span><\/td>\n<td><span style=\"font-weight: 400;\">NoSQL systems at times overlook data integrity to deal with the enormous data points.<\/span><\/td>\n<\/tr>\n<tr>\n<td><b>8<\/b><\/td>\n<td><b>Data Storage<\/b><\/td>\n<td><span style=\"font-weight: 400;\">SQL databases store data in tables.<\/span><\/td>\n<td><span style=\"font-weight: 400;\">NoSQL databases store data in the form of collections.<\/span><\/td>\n<\/tr>\n<tr>\n<td><b>9<\/b><\/td>\n<td><b>License<\/b><\/td>\n<td><span style=\"font-weight: 400;\">SQL systems come with a license and need payment after a certain period of time.<\/span><\/td>\n<td><span style=\"font-weight: 400;\">NoSQL systems are available under the open-source license and thus are free to use.<\/span><\/td>\n<\/tr>\n<tr>\n<td><b>10<\/b><\/td>\n<td><b>Principle<\/b><\/td>\n<td><span style=\"font-weight: 400;\">SQL databases work on the ACID[Atomicity, Consistency, Isolation, and Durability] principle.<\/span><\/td>\n<td><span style=\"font-weight: 400;\">NoSQL databases work on the CAP[Consistency, Availability,<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Partition Tolerability] principle.<\/span><\/td>\n<\/tr>\n<tr>\n<td><b>11<\/b><\/td>\n<td><b>Community Support<\/b><\/td>\n<td><span style=\"font-weight: 400;\">SQL is an old market holder and has a large community for support and development.\u00a0<\/span><\/td>\n<td><span style=\"font-weight: 400;\">NoSQL is comparatively new and thus is weak when it comes to community support.<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h3>Summary<\/h3>\n<p>The choice between using SQL or NoSQL for big data depends on the individual and the circumstances as both of them have some pros and some cons.<\/p>\n<p>SQL databases are reliable as they have been available for a long time in the industry. They have a fixed schema defined beforehand with the set rules for the data.<\/p>\n<p>Thus, they are ideal for applications that require multiple transactions like an accounting system.<\/p>\n<p>While on the other hand, NoSQL databases are easy to scale, flexible, and simple to use as they have no fixed or pre-decided schema.<\/p>\n<p>They are ideal for applications with flexible schema definitions such as analytics and content management platforms.<\/p>\n<p>Thus, we can say that the choice of database to be put to use is subject to one\u2019s requirements.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In this tutorial, we will learn all about SQL and NoSQL databases.
