Top 15 Uses of SQL Programming Language [Updated For 2024]
According to the latest statistics by an authorized organization on SQL programming language, SQL is used by 40% of all developers and has become the world’s 4th most used language as per TIOBE Index 2022. This is because SQL has great uses and applications.
As a developer, you can use this language in various ways including data aggression, data integrity, data creation, transaction management, indexing, and much more. And yes, we are going to explain the top 15 uses of this programming language in detail below.
All you need to do is, stay with this page and be good to go. Let’s dive right into this.
What is SQL (Structured Query Language)?
SQL or structured query language is used by relational databases to manage and manipulate their data and promote efficient querying systems inside the database. By using this programming language, you can make applications or pursue web development projects simutaneously because of its easy integration system.
In fact, we are going to share the great benefits of using SQL in your projects below.
Top Uses of SQL Programming Language
Explore the top features of SQL programming language one by one. This is to aware you of the possible ways you can benefit from Structured Query Language.
Let’s get straight into this.
Database Creation
The top use of SQL language in our list is the creation of databases using this. This programming language allows you to use different commands and constraints. Using the commands, you can create tables, establish and specify the relationships between them, and set up the constraints.
For ease in creating databases, SQL also offers primary and unique keys to ensure all the data you have stored in different tables adheres to the specified rules you have explained.
Data Validation
You can easily and quickly validate the data using SQL language. It provides you with various essential tools such as constraints and keys. With them, you can check whether your data is accurate, and follow the specified rules or define the relationship.
You can also modify, create backups, and ensure the best structure of your data for better validation using SQL programming language.
Data Analysis
Another top-notch use of SQL programming language is that you can promote deep data analysis with it present in your database tables. You can apply various conditions and filters to find out the specific table, data inside, or information. This is to derive the required insights and to make perfect decisions using the extracted data.
This feature of SQL is quiet helpful especially when you’re dealing with large datasets or working on very large databases.
Data Retrieval
Using SQL language you can also retrieve the data from your database. Meanwhile, the exactly required data on user-specified criteria. This feature is specially designed for large organizations and businesses looking to quickly find information, make queries, and generate reports for better analysis and decision-making.
Data Modification
SQL is the programming language that offers various commands to the users. Talking about some famous commands, they include INSERT, UPDATE, and DELETE. These three commands add great value to its functionality.
Meanwhile, you can use these commands to add new data, modify the existing data, and even delete outdated data. This is how you can ensure your program is up to date and promoting better functionality.
Access and Control
You can enjoy the extra security layers for your program using SQL programming language because it supports great authentication and authorization. As an administrator of your project, you can easily manage the access and control. You can decide who is allowed to add new data, modify the existing things, and even delete something.
Interestingly, you can also block unauthorized access to your program with SQL programming language by following a few simple steps.
Data Integrity
Using SQL programming language you can ensure great data integrity. The programming language is providing you with primary and foreign keys that can help you check the accuracy and management of data. Apart from this, SQL is also providing you with unique constraints which is a remarkable feature of this language.
Using these unique constraints, you can specify the rules for the relationships between tables embedding data. This is how you prevent invalid and inconsistent entry of data to avoid any error.
Data Aggregation
SQL programming language also allows you to do data aggregation. It provides you with tools or functions SUM, AVG, COUNT, etc. With these, you can easily summarize your large form of data and get a broader view or insight. Now, you can use this feature of SQL, get statistical analysis, summarize reports and make valuable decisions.
Stored Procedures
Using SQL, you can use the pre-stored and reusable sets of pre-defined statements in the database and can avoid writing and executing codes with commands again and again. In this way, you can enhance the database management and excellent performance.
Transaction Management
Using SQL, you ensure better data integrity and transaction management which follows the ACID properties. Meanwhile, atomicity, consistency, isolation, and durability. This is how your programs ensure the successful execution of multiple SQL statements, consistent transactions, and grouping in atomic units.
Creation and Management of Indexes
SQL promotes the creation and management of indexes. These are basically structures that enhance the speed of data retrieval operations on a database table. By creating and managing indexes using SQL language, you improve query performance and speed up the retrieval operations as well.
Data Migration
With SQL, it's very easy to migrate your data within databases or even within the same database. You need to use appropriate queries and statements, and that’s all. By using the “SELECT” query, first select the data you want to transfer. After that, load the selected data into the corresponding tables using INSERT statements.
Generating Reports
SQL also allows you to easily generate reports of your desired data from your project database. Firstly, you need to organize and compile the data to be reported using tools and techniques. For example, you use the “SELECT” query to select the desired data, promote grouping, and summarize according to your reporting requirements.
Once you are done with all this, export the reports and make perfect decisions based on the insights or extracted data.
Data Backup and Recovery
Recovering or backing up your data is very simple with SQL. You only need to know about the right commands and methods of implementation. Here are the commands for both data recovery and data backup.
- The command for data recovery: 'RESTORE DATABASE [DatabaseName] FROM DISK = 'C:\Backup\BackupFile.bak'.
- The command for data backup: 'BACKUP DATABASE [DatabaseName] TO DISK = 'C:\Backup\BackupFile.bak'.
Use these commands and promote data recovery and data backup easily.
Integration with Programming Languages
SQL doesn’t irritate when it comes to integration with other programming languages like Python, Java, and C#. You only need to use APIs and connectors to promote better communication and integration, that’s all.
If you’re looking for an SQL developer to help you complete your project or achieve a higher success rate, here’s your destination.
