SQL VS Python | Newtech Academy

If you have already been on our blog, you already know that SQL and Python are two of the most popular programming languages ​​used in the management and analysis of the data. Each has its own strengths and specific applications. But what is most suitable for your needs? Well, at the Newtech Academy, we understand that the correct choice can make the difference between success and failure in a project. That’s why our courses cover SQL and Python, giving you a complete perspective on the available tools.

First of all, SQL (structured query language) is the standard language for the management of relational databases. It is ideal for questioning, updating and organizing structured data in the tables. If you work with databases like MySQL, Postgreql or Microsoft SQL Server, SQL is an essential ability.

On the other hand, Python is a general programming language, known for versatility and ease of use. It is widely used in data science, automatic learning and web development. With the help of specialized libraries such as Panda, Number and Scikit-Learn, Python becomes a strong tool for data analysis and modeling. It remains with us because we will continue to analyze in detail the key differences between SQL and Python, highlighting the advantages and disadvantages of each. We will discuss concrete use cases, to help you understand when it is more appropriate to use one or the other.

SQL, in short, is the language used to communicate with relational databases. With its help, you can extract, modify or delete the information and even change the structure of the database itself.

SQL features

• Simplicity for beginners: SQL is surprisingly easy to learn. Even short and simple queries can perform complex operations. For example, we take an online shop of sporting goods that retain all the details on the products in a table called «Products». To discover the price of a product with the A5E4EQZWE code, you just need this question:

SQL

Select the price from the products in which Sku = ‘A5e4eqzwe’;

And if you want to change the price, the order is equally simple:

SQL

Update the products set price = 25.5 where Sku = ‘A5E4EQZWE’;

• Equal efficiency: SQL can quickly process a complex and voluminous query, being the perfect tool for data analysis. Team of various sectors, from sales to finance, use to extract precious information and make strategic decisions.
• Dialects and limitations: Although SQL is a standardized language, there are small variations, called dialects. MySQL, Postgressql and Microsoft SQL Server are examples of these dialects. Fortunately, they are largely compatible with each other and the transition from one to the other is not difficult.
• A specialized tool: SQL is specially designed for work with databases. It is not possible to use it to create complex applications or algorithms. However, for data analysis, this limitation is not a serious impediment.
• Data Revolution: SQL has democratized access to information. Even without experience in programming, anyone can quickly learn to work with great volumes of data. With a few orders, you can discover interesting and relevant information. SQL is accessible and strong, a rare combination in the world of technology.
• Reliability and adaptability: SQL works perfectly in any environment, from small databases on a personal laptop to complex online systems. Even in a constantly changing technological panorama, SQL remains an essential and reliable tool for data management.

What is Python?

Python, simply said, is a programming language used for a wide range of applications. From the creation of websites and computer applications, to the development of complex algorithms or to the automation of repetitive tasks, Python can cope with the panache. Games also find their place in this vast programming universe.

Python functionality

• Easy to learn, easy to use: Python is famous for its simple and easy to treat syntax, being an excellent choice for those who take the first steps in the programming. Here is an example that calculates the circumference of a circle:

Import mathematics

Def calculate_circumference (radius):

Return 2 * Math.pi * Raggio

ray = 2

circumference = calculation_circumference (radius)

PRINT (F «Circumference of the circle with radius {radius} is {circumferences: .2f}»)

The code is clean, airy and easy to read, isn’t it? Python requires the use of returns, which makes the code more organized and easier to follow.

• Versatility and data science: Python is a versatile language that states in particular in the field of data science. There are numerous bookcases and work frames specialized for data analysis and automatic learning. The number, for example, is a popular library to manipulate large data sets.
• Career opportunities and prospects: Knowledge in Python can open attractive wages and interesting career opportunities. Many companies are looking for Python specialists and are willing to pay well for their talent. This language is used in a variety of sectors, from web development to artificial intelligence, and its popularity continues to grow due to its active community and constant updates.
