SQL: Definition, Functions,
And Professions That Need It
Currently, programming languages are very diverse for use in various types of applications for desktop, mobile, or tablet devices. One of the programming languages is SQL. SQL is Structured Query Language which means a query language used as an information manager in a database. For beginners, SQL is a language that functions to access data that is in a relational basis. Currently, not a few developers use SQL to help design database needs in applications.
SQL Functions
There are several functions of SQL that you should know. Check out information about some of its functions as follows
1. Able to Execute Queries
The first function of SQL is to be able to execute various existing queries. So the first function directly orders the system to manage the database. Examples of query execution include trigger, alter, giant and many more.
2. Able to Manage User Access Rights
The next function is to manage user access rights. This is interpreted as regulating and managing the need for table access rights, views and procedures in the database. The purpose of this access right is to limit access to use according to the needs of the system being implemented.
3. Able to Manipulate and Access Databases
The last function is being able to access databases by writing several commands according to the specified query. You update data in the form of adding data, deleting data, or changing tables and some unimportant information.
4. Able to Create Tables
Objects that are often used to store all data in this database can be created from SQL. The location of the table in the database where the table is created after a database has been created. The table itself has rows and columns where the row is called a recordset and the column is called a field. The database must be activated first to create a table or more.
5. Viewing Table Structure
- After creating a table, you can see the data type and column length by displaying the table structure.
- Professions That Require SQL Skills
- After discussing the definition of SQL and its functions, next you need to know what professions require this SQL skill. Most of the professions are in the data field, this is because SQL is closely related to data processing. Here are some professions that require SQL skills:
1. Data Engineer
The responsibility of a data engineer who must find trends or patterns in data sets. Developing algorithms to transform data to make it useful is also his responsibility. Developing algorithms to make accessing raw data easier is also his job. Therefore, a data engineer must be able to master SQL. This is an important function of SQL for data engineers that must be learned. Without SQL, a data engineer cannot run a program properly for the company.
2. Data Scientist
The next profession that must master SQL is someone who is involved in creating databases. Processing data and translating it into something that is easier to analyze, yes, he is a data scientist. The data products produced by a data scientist will later be used as a reference for a company to make business decisions and other policies. Therefore, this job is closely related to data and must be able to have data processing skills with SQL.
3. Database Administrator
Managing database software such as storing, compiling and accessing data with a mature system is his job. This database administrator section oversees SQL programmers, who must definitely master this programming language. As the superior of SQL programmers, database administrators must be able to evaluate work and provide input if errors occur.
4. Business Analyst
Next, a profession that must be able to use SQL is a business analyst. This profession is tasked with guiding companies in creating processes, products, services and software through business analysis. Running a gap analysis to identify steps to advance the business is one of the tasks of a business analyst. Gap analysis requires SQL to find gaps in existing data. The key to a business analyst’s success is being able to analyze gaps in detail.
5. Quality Assurance Tester
Generally, a quality assurance tester is tasked with checking for damage or problems in digital products such as applications, software, games, and websites. A digital product stores user information using a SQL-based database. A quality tester must master SQL in order to be able to find out details related to the damage so that it can be repaired.
