What Can SQL Be Used For?

  • by

SQL (Structured query language) is an underlying programming language for data that is mostly used to manipulate and query the data stored within relational database. This is an advanced language since it’s hardware-independent and thus is utilized by a variety of businesses to manage their databases. The benefits of knowing SQL are increasing and significant. SQL has seen a dramatic rise in its use over the past few years.

Below are some benefits of using SQL:

1. Speedier and more efficient query processing

SQL operates at a high speed. This speed boosts the speed information retrieval. It gives users the ability to quickly and efficiently to access, modify and store information.
SQL can be used to quickly and effectively access a huge amount of data records from databases. In contrast to a non-structured database, such as MongoDB It is a relational database which can categorize records in a structured fashion. Operations such as insertion, deletion and querying, as well as manipulation and calculations on data through analytical queries within a relational database are done in only seconds.

2. No need to Coding Skills

There is no requirement for complex and large codes for data extraction. One of the advantages of using SQL is because it doesn’t require the use of a lot of code and programming skills. It is simple to manage databases without writing an enormous amount of code. There is no need to write huge, complex lines of code to perform extraction of data.
SQL is primarily composed of English statements, which makes it simple to understand to create SQL queries. The most important keywords, such as SELECT, INSERT INTO UPDATE, DELETE etc. can be utilized to execute operations. Additionally, the syntactical rules are straightforward and simple to comprehend which makes it a very user-friendly language.

3. Portable

The ability to transfer data is a highly important feature for any software that store information in the database. Software developers want to make use of a tiny memory-based database, like Apache Derby, while creating an application.
SQL is extremely portable since it is used in applications that run on servers, PCs tablets, as well as independent laptops that run operating systems like Windows, Linux, Mac as well as certain mobile phones. It is also possible to integrate in other programs depending on the specifications.
It is able to be utilized in local networks (internet and intranet). SQL databases are effortlessly transferred from one system to the next.

4. Standardized Language

SQL is an open-source database query language which has been recognized from ISO as well as ANSI. It provides all users with an unidirectional platform across the globe because of the proper documentation and the many years of existence.
In the years 1986-1986 and 1987-1987, ANSI (American National Standards Institute) and ISO (International Standards Organization) standardized the language. The most recent standard version was published in 2011-2011.

5. Interactive Language

SQL is a domain-specific language that is easy to master and is easy to comprehend. It is also able to connect with databases, and to receive responses to complex queries in a matter of minutes.
It’s an active language users since it provides simple commands that can be used for any purpose. SQL commands are also easily understood by non-programmers.
SQL is utilized to create and manage databases that are large which include sharing of data as well as updating and retrieval from many tables. This is the main reason that organizations utilize SQL for various purposes like web development and analysis of data IT support, and so on.

6. Multiple Data Views

The SQL language offers each user an exclusive view of data. A view is an SQL statement that contains specific SQL queries which are stored within the database. It is constructed by combining tables that are based on the query written or on the goal to satisfy.
SQL online provides different views of the database’s structure as well as contents to different users.

7. Internet Usage

Three-tier Internet architectures can be used to SQL architecture. The application server and client and database components comprise the structure.

8. Large User Community

SQL is a programming language has a lifespan of more than 50 years old. It is extremely mature and widely utilized. It is a vibrant community of specialists who are eager to give guidance and best practices that are well-established.
There are many opportunities to develop one’s skills and work together. Consulting firms and SQL suppliers can offer additional assistance, if required. The developers you hire will be able get the answers they need through SQL.

What are the disadvantages of SQL?

In addition to its benefits it is also a disadvantage. SQL (Structured SQL Query Language) has a few drawbacks :

1. Resource-Intensive Scaling

SQL databases usually increase their vertical size by increasing the investment in hardware. This can be costly as well as lengthy. An organization could seek to increase the size of an SQL database horizontally, using partitioning in specific circumstances.
The added complexity adds amount of time and money needed. This will require programming to handle the massive database. This requires highly skilled and highly paid developers. The process of scaling an SQL database as the volume of data increases is similar to playing a never-ending game tag, where the best configuration is never of reach.

2. Partial Control

SQL doesn’t give programmer with full access to databases. This is due in part to the hidden corporate rules.

3. Cost Inefficient

Certain versions are expensive and make programmers inaccessible to use the versions. For instance, SQL Server Standard costs about $1,418 per year.

4. Rigidity

The schema of an SQL database needs to be established prior to its use. They’re not flexible once they’ve been installed and updates are typically difficult and time-consuming. This means that a significant amount of effort must be put into initial preparation prior to the database being ever released into production.
They’re only helpful in the event that all your data is well-organized and you don’t expect an enormous amount or type changes.

5. Normalization of Data

The relational databases, designed at a time where storage costs were high Try to reduce duplicate data. Each table contains unique data that can be connected and accessed with common values. However as SQL databases increase by size, number of lookups and joins that are required between several tables could result in performance issues, eventually slowing things down.

6. Hardware Update

The standard procedure to use SQL databases is that they increase the size of the data vertically. This the capacity is increased by adding features like RAM, CPU, or SSD on the existing server or moving it to a bigger and more costly one. As your database grows you’ll require more space on your hard drive and more powerful equipment to work with the latest and advanced technology. Your database provider will most likely need you to upgrade your hardware on a regular basis to ensure that you are running their latest releases.
Hardware is prone to becoming outdated in this case. Every update will cost a lot of money and consume a lot of resources. SQL’s hardware requirements are ongoing maintenance and day-to-day expenses.


SQL (Structured SQL Query Language) is now one of the most used databases languages. It is a specific domain query language that is used extensively to build and manage databases through actions such as INSERTION, DRELETION and UPDATION of an existing schema.

The International Organization for Standardization and the American National Stands Institute have adopted it as an international standard. The majority of organizations and companies employ it to effectively control their development and database projects.
