Structured query language or SQL is used as a medium of communication with the relational database management systems. This standardized language helps data analysts to analyze, retrieve and update data or records that are encompassed inside the database. Also, this tool is commonly used to store structured data.
There are a variety of relational databases, including Oracle, Microsoft Access or Server, and each of these have minor variations as they belong to different brands, while the structure of the language is more or less the same. SQL exposes the users to the data in the records via the following instructions implemented in the syntax:
SQL queries are formulated to perform a wide range of tasks, including maintaining and analyzing structured data. Though, the use of SQL could vary from one person to other, as well as business requirements, some of the common applications include:
This standard tool helps users to manage a variety of functionalities, such as record management, quality control and data analysis. With SQL, you can easily complete all communications with or within the databases.
As you know, you can implement Excel or spreadsheet apps to store small chunks of data that are less in number. This could extend up to thousand records. But, what can you do when the record list exceeds thousands, say above hundreds or millions of thousands transactions or data records? This is where SQL has a great role to play in dealing and managing the entire database and these include:
SQL is the best choice for data analytics as it provides a lot more sustainability when it comes to dealing with greater and enormous chunks of data. If you want your data assets to flaunt a greater deal of expansion, then the SQL database is the best environment to help you enjoy a great transition.
We can simply say that SQL is that structured language, which can be used to create, maintain and manage the data that lies within a database. The definition for database is that it is a structured architecture that has been programmed to organize data, defined by meta data, which ultimately expresses the structure.

This is how SQL is considered to be an all-inclusive language as well as being a powerful tool that helps in controlling the functionalities while powering the interaction with the computer’s database system.
Though, relational database (RDBMS) has been playing a prominent role as a dormant model of database, the non-relational cloud or NoSQL database is replacing these traditional norms.
NoSQL is an approach apart from the conventional technologies implemented by relational database management systems (RDBMS). RDBMS implements SQL, which we have discussed in the aforementioned points and will be soon discussing further. As you are aware, RDBMS largely relies on rows, columns, schemas, and tables, for retrieving and organizing data stored in the databases, all this works different when it comes to NoSQL.
NoSQL databases can perform their functionalities and carry out their operations without the help of any of these structures. They are capable of implementing data models that are more flexible. NoSQL also known as not only SQL or not SQL implements techniques that helps in avoiding redundancies and inconsistencies that pops up usually when the traditional technologies of RDBMS is implemented. RDBMS comes with certain areas of concerns, such as non-scalability, non-flexibility, and performance issues, which the modern day applications are looking for NoSQL solves all these intensive scenarios and helps data intensive apps to flourish.
Whenever there is a lot of unstructured data that needs storage, NoSQL can be used as it can accommodate structured data largely which fail to fit inside the traditional relational schemas or RDBMS. Some of the common unstructured data include: chat, messaging, log data, user and session data, large data such as videos and images as well as internet of things and device data.
On the basis of your project requirements, user needs, and data-intensiveness, you can choose the one that fits all the needs within an affordable budget.
Here, we have listed out an overview of both SQL and NoSQL along with their pros and cons. You can decide the best based upon the business requirements, cost and time you have to implement either of them.
