WHAT IS SQL?

SQL is a Structured Query Language is a domain-specific language used in programming and designed for managing data held in a relational database management system (RDBMS), or for stream processing in a relational data stream management system (RDSMS). It is particularly useful in handling structured data, i.e. data incorporating relations among entities and variables.

SQL offers two main advantages over older read–write APIs such as ISAM or VSAM. Firstly, it introduced the concept of accessing many records with one single command. Secondly, it eliminates the need to specify how to reach a record, e.g. with or without an index

10 USES OF SQL

1. Alter data within a table

If you access a database that has organized data within a table, you can use SQL to manipulate this data. For example, you can change certain data points within the table. Additionally, you could alter every section of the table with updated data. This is a very common use of SQL.

2. Create a table

Another use of SQL is the ability to create a new table. Users may create a brand new database by adding new data into a table once it’s created. This function allows users to contribute data to the system, which can further analyze, manipulate and store it.

3. Retrieve data

Many data scientists can use SQL to retrieve data from within the database. The process for this in SQL is DQL, which stands for Data Query Language. After retrieving the data, it’s easier to analyze and assess it. The syntax for this command is “SELECT.”

4. Change data structure

Another use of SQL is to change the structure of the data. You can do this by changing the database or table where the data’s stored. A professional may use SQL for this purpose if there’s new data that makes the current storage process outdated.

5. Define the database’s schema

You can use SQL to define your database’s schema, which contributes to data descriptions and structuring. The name of this process is data definition language, or DDL. The commands you can use for this process include “CREATE,” “DROP,” “ALTER,” “TRUNCATE,” “COMMENT” and “RENAME.”

6. Manipulate the data

You can use the DML, or data manipulation language, feature to store, modify, delete or update the data. You might use SQL for this purpose if you want to refresh the whole database to ensure it’s accurate and updated. The commands for this include “INSERT,” “UPDATE” and “DELETE.” Here’s an example of how to use these commands:

7. Grant access to data

If you manage the database, you can provide access to other users using SQL. The method for this is DCL, which means data control language. You can use the commands “GRANT” and “REVOKE” to determine which users have access to which databases within the program. This use may benefit businesses that store confidential or sensitive data within the program.

8. Define user functions and procedures

Using SQL, you can add functions and procedures based on your specific database needs. For example, you can link simple SQL syntax to a specific command before you begin using the system. This helps you meet the requirements for your business and simplifies the process of using the language.

9. Analyze data manually

You can use SQL to manually analyze the data within your system. This may be necessary when you need to intervene with the system manually. While troubleshooting or solving an issue with the database, manual analysis can provide an alternative way to continue accessing the data. Users can use SQL queries to search for necessary data, which they can then use for analysis.

10. Combine datasets

The SQL Join function allows users to combine data from two sets. You might use this feature if you want to combine and compare two different tables. You can use the following commands:

  • (INNER) JOIN: This command can show the programmer if any outputs in the two systems are overlapping. For example, if there are multiple outputs classified as “REVIEW,” this function shows each of these outputs.

  • LEFT (OUTER) JOIN: This command shows the user every aspect of the left-hand table, and compares it to the outputs of the other table.

  • RIGHT (OUTER) JOIN: This command shows the user every aspect of the right-hand table. Then, it compares these aspects with the outputs of the left-hand table.

  • FULL (OUTER) JOIN: This method completely joins the two tables together. It can show a user all the areas where data matches between the two tables.
