What Is SQL Programming Language? Benefits, Limitations, and More!
SQL is a structured query language that is primarily used by relational databases to manage querying systems and manipulating data. SQL also defines the data structure and ensures a smooth experience.
According to the Zipdo.co Research on SQL Statistics, SQL is used by 40% of all developers worldwide and is the 4th most popular programming language as per TIOBE Index 2022. This is how you can get an idea of SQL's popularity in the tech industry worldwide.
In this article, we are going to share everything about SQL in detail. The benefits, advantages, limitations and all other important points which should be discussed. All you need to do is, stay with this page and dive right into this content for the latest information about SQL.
What are the Benefits of SQL Language?
There are a lot of benefits related to the data you can enjoy using SQL languages. You can also add more security layers, ensure better indexing, and much more. Let’s discuss all of them in detail.
Database Creation and Validation
SQL in terms of database creation allows you to use commands for creating tables (rows and columns), establishing relationships between them, and setting constraints. Using constraints like primary keys and unique keys, you ensure the stored data in the tables adhere to the specified rules.
In terms of data validation, SQL provides various essential tools such as constraints. You can check data for accuracy, and define relationships between tables, backups, modifications, and more. This is how you maintain structure and accuracy.
Data Analysis and Retrieval
SQL also offers essential tools with which you can perform deep data analysis. You can apply conditions, and filters and extract specific information to derive insights and make the right decisions based on extracted data. You can use SELECT statements and find information from large datasets.
With SQL, you can also retrieve the exact required data based on user-specified criteria. Using the feature of Structured Query Language businesses can quickly find specific information, make inquiries, and generate reports.
Data Modification and Security
SQL language allows you to easily modify the data in your databases. All you need to do is use commands like INSERT, UPDATE, and DELETE. By using these commands, you can add new data, update existing one, and even delete specific data.
In terms of security features, SQL supports great authentication and authorization. It allows you to manage who can access the data, change or improve, and even delete. You can also block unauthorized access.
Stored Procedures
SQL also benefit you in terms of providing pre-stored and reusable sets of pre-defined statements in the database. You don’t need to tackle complex commands or write codes again by putting your efforts.
Indexes Feature
By using SQL, you can create indexes which can enhance the better query system and optimize the speed of data retrieval operations. This is how you better database management and manipulation.
Data Reports
The SQL also allow you to generate specific reports of your desired data from the database. Simply, organize the data using appropriate query. For example, use “SELECT” query to select the data, do grouping and summarizing to organize the data. Once you done with this, export the reports. These reports and insights will later help you make right decision.
Excellent Transaction Management
Transaction management follows ACID properties which are atomicity, consistency, isolation, and durability. With SQL, you ensure excellent transaction management and data integrity which further help you successfully execute multiple SQL statements and grouping in atomic units.
Data Recovery and Backup
Using SQL, you can also easily recover or backup your data from database. Just understand the appropriate commands for both functions and you’re good to go. See the commands you need to use for recovery and backup:
1. The command for data recovery: 'RESTORE DATABASE [DatabaseName] FROM DISK = 'C:\Backup\BackupFile.bak'.
2. The command for data backup: 'BACKUP DATABASE [DatabaseName] TO DISK = 'C:\Backup\BackupFile.bak'.
Now, let’s discuss some limitations for structured query language (SQL) below.
Some Limitations of SQL Programing Language
Where SQL provides great advantages, it also has some limitations. These may be some performance errors or other issues. You should know them before starting a project with SQL to tackle them easily.
Let’s explore them one by one.
Only Relational Model Constraints
SQL only supports relational database model constraints which is not suitable for hierarchical or graph-based data. Meanwhile, not suitable for all types of data. In contrast, other database models such as NoSQL offer more flexibility.
Limited Support For Complex Queries
SQL supports straightforward queries and is also efficient, but sometimes it comes up with errors when you perform complex queries. You might face performance issues and less efficiency.
Issues with Big Data Analysis
SQL mainly promotes efficient management of data but it causes issues when you perform big data analysis. Your program will experience less efficiency and slow performance when you go for adding specific queries or filters for big data management and analysis.
Performance Errors with Large Databases
You cannot enjoy optimized performance and speed during the runtime of your software if you have a very large database. As the volume of data grows, you might face errors and slower performance in retrieving, updating, or deleting records.
Poor Hierarchical Data Support
You need to be expert enough to promote hierarchical data management in your databases using SQL language. You cannot create a tree-like structure easily, especially when you have a large database. To create a Hierarchical data structure, first master SQL and understand the techniques like recursive queries.
Concurrency Control Challenges
Using SQL language, multiple users or applications cannot manage concurrent access at the same moment. Although, mechanisms like transactions are offered by the Structured Query Language but still handling concurrent updates is a challenging task.

FAQs
Is SQL Considered a coding/programming Language?
Yes, SQL is considered a coding/programming language that was specially designed to manage and manipulate rational databases such as MySQL.
What are the Four Main SQL Languages?
There is only one SQL language while sublanguages are also sometimes counted as SQL types a misconception. However, they are Data Query Language (DQL), Data Definition Language (DDL), Data Control Language (DCL), and Transaction Control Language (TCL).
Is SQL Easier Than Python?
Which language is easier for you depends on the context and your project-related requirements. If you are doing something database-related, SQL might be simpler for you. On the other hand, if you’re doing something purely related to the vast programming, Python might be easier in that case. SQL is purely for working with databases, while Python is for general-purpose programming.
Which SQL Language is Most Used?
SQL or Structured Query Language is only one single language, while it has sublanguages. It is used by various rational databases including PostgreSQL, Microsoft SQL Server, and MySQL.
What is the difference between SQL and MySQL?
SQL is a Structured Query Language that is used by relational databases for managing their querying system. In contrast, MySQL is a relational database management system that uses SQL as its query language.
