Many companies need SQL Dev
The rate of recruitment in companies that recruit programmers such as (itjobs, itvec, topdev.vn , topitwork) recruiting SQL dev positions is the most. Compared with positions of Dev Java or PHP, JS, Python, C + …, SQL is preferred by many companies.
Easy to edit
The point I like the most when using SQL is also its strongest point, it’s easy to edit. You will check and manipulate data more easily. Moreover, the data stored in SQL is dynamic, meaning you can modify and manipulate it at any time with some basic SQL queries.
There is a matching function from the source
For other types of programming languages combining data from two or more sources can be time-consuming and difficult. However, SQL makes this process easier by supporting simple “merges”.
Easily manage data
The SQL language helps you manage large data groups easily and very simply. While you can still use traditional spreadsheets to manage small and medium ranges of data, you will need another solution like SQL for handling large groups of records.
Easy to manage
SQL is quite a useful tool for developers who are managing a server, or creating their own. Many servers use databases like MySQL or SQL Server to store data. By familiarizing yourself with SQL and its associated queries, you can more easily manipulate other data websites that are more difficult to use.
Simple and convenient as Excel
Using good office tools like excel, word, knowing SQL will help you a lot in the working process that requires expertise and high flexibility. Especially the trend of business on data-driven data.
Common SQL, many applications
Most companies now store data with a database management system, so knowing SQL will help you have more opportunities and career advancements.
