What is the use of SQL language in database management?
Posted: Tue Jan 21, 2025 6:26 am
There are many applications of the SQL language related to the management of information found in databases. These provide plenty of reasons for Big Data specialists to know how to handle solutions like this one.
Data retrieval : This is one of the key functions, as it allows analysts to access stored resources quickly and easily. It usually offers the option of filtering by certain criteria and sorting results, making the activity easier.
Manipulation of information : the documentation obtained can be used in different ways. Calculations can be made, data sets can be combined, others can be modified… It is a very versatile resource, hence its great usefulness and the potential of its application.
Integration of different sources : SQL language makes it easy to combine information found in different databases. This allows Big Data professionals to create more complex reports thanks to the great diversity of resources and information that can be gathered.
Creating data summaries : Analysts can develop comprehensive reports by using different ways to use SQL , combining it with metrics and values, among other aspects.
Sift through the resources you have : clean the data, eliminate duplicates, process those that have been omitted, standardize the format in which they have been saved, etc. This afternoon of 'cleaning', so to speak, is important for the optimal functioning of this very specific programming language.
Scalability of different database management systems , allowing analysts to work with different sources in an agile, easy manner and without much margin for error.
Optimize data queries to the maximum : the time required kuwait whatsapp data to access information and stored data is reduced.
Data analysts must always strive for specialization and go beyond their knowledge of the world of Big Data. EAE Business School Barcelona has two specialized and very complete programs in this regard, which cover the SQL language , among other resources and applications. We are referring, on the one hand, to the Global Master in Business Analytics and Data Strategy ; on the other, to the Master in Big Data & Analytics . Both are highly recommended for those who want to improve their knowledge in this field.

SQL Language for Data Analysis: How to Use SQL to Extract Useful Information
When it comes to understanding how the SQL language works to manage information, it is important to highlight that it is a broad and complex subject, so the main lines are given below so that the reader can get an idea of what to start from. In the case of data extraction, which is what these resources are especially used for, these steps can be followed:
Identify the sources from which you want to obtain resources.
Connect to the desired database, using the appropriate tools.
Establish a secure connection using the appropriate credentials.
Write SQL queries in the selected language, defining the criteria for selecting and sorting the information.
Run those queries and check the results to ensure that everything was done correctly.
Export the data in the required format to later analyze the information obtained.
The relational databases referred to throughout the article are cases such as MySQL, MS Access, MS SQL Server… As also pointed out in previous paragraphs, the information is structured in rows and columns with details that provide relevant references in order to subsequently refine the results of the searches that are executed.
As you can see, when talking about this programming language , an introduction to SQL is included here , since it is a complex subject that must be addressed by specialized professionals. Big Data – data analysis – is a booming area of activity, hence the importance of data analysts expanding their knowledge and knowing which are the key resources to carry out their functions with total efficiency.
