Basic SQL : what is it?

For a very long time, SQL was reserved for knowledgeable and technical people in the IT department, and not just any company entity or department could do it. It used to be the exclusive preserve of the company’s IT department. Now, with the spread of « IT », many departments are able to access their company’s data using SQL to query their databases, including marketing, accounting, management control, human resources and many others!

Are you a company specialising in e-commerce, healthcare, retail or simply an SME / SMI? Do you have a set of data stored in a database?

It’s essential to know the basics of structured query language (SQL) so that you can quickly get answers to your queries.

DEFINITION

SQL, or Structured Query Language, is a programming language specially designed for managing and manipulating relational databases.

It provides a standardised interface enabling users to communicate with databases and carry out operations such as inserting, updating, deleting and retrieving data efficiently.

THE BASICS OF SQL

Remember that SQL is nothing more than a way of reading the contents of a relational database to retrieve the information a user needs to meet a requirement.

DATA STRUCTURING

SQL is based on the relational model, which organises data in the form of tables. Each table is made up of columns (fields) representing specific attributes, and rows containing the records.

Table structure :

In the world of SQL, table structure is crucial. Each table is defined by columns, where each column represents a particular attribute of the data you are storing. For example, an « employees » table might have columns such as « surname« , « first name« , « age« , etc. These tables are linked by keys. These tables are linked by keys, which can be unique identifiers for each record, facilitating relationships between different tables.

The main operations (or commands / basic SQL queries)

SELECT : Used to extract data from one or more tables. The SELECT clause is used to specify the columns to be retrieved, the filter conditions and the sort order. This clause is one of the most fundamental in SQL. The WHERE clause, often used with SELECT, is used to filter the results according to specific conditions. For example, you might want to retrieve only those employees whose age is greater than 30, or as in the example below, only those employees in the sales department.

SELECT last name, first name FROM employees WHERE department = ‘Sales’;

INSERT: Used to add new rows to a table

INSERT INTO customers (last name, first name, email) VALUES (‘Doe’, ‘John’, ‘john.doe@email.com’);

UPDATE: Used to add new rows to a table

UPDATE products SET price = price * 1.1 WHERE category = ‘Electronics’;

DELETE: Used to delete rows from a table under certain conditions

DELETE FROM orders WHERE order_date < ‘2023-01-01‘;

Filtering and sorting

To filter the results, SQL uses the WHERE clause, which allows you to specify conditions for selecting the data. In addition, the ORDER BY clause is used to sort the results according to one or more columns.

Filtering and sorting are essential operations in the SQL language, making it possible to retrieve specific data and organise it in a meaningful way. Let’s explore these concepts with some practical examples

Filtering with the WHERE clause

The WHERE clause is used to filter the results of a query by specifying conditions. This allows you to select only the data that meets these criteria.

–Select employees with a salary greater than 50000

SELECT last name, first name, salary

FROM employees

WHERE salary > 50000;

In this example, only employees with a salary greater than 50000 will be included in the results.

Filtering with the ORDER BY clause

The ORDER BY clause is used to sort the results of a query according to one or more columns. You can specify the sort order (ascending or descending)

–Select customers and sort alphabetically by name

SELECT last name, first name, email

FROM customers

ORDER BY name ASC;

In this example, the results will be sorted in ascending alphabetical order by customer name.

Filtering and sorting can also be combined, i.e. combining the WHERE clause and the ORDER BY clause to filter the results at the same time

–Select products in the ‘Electronics’ category and sort by descending price

SELECT product_name, price

FROM products

WHERE category = ‘Electronics

ORDER BY price DESC;

There are other ways of filtering and sorting with operators, but this becomes SQL that is no longer basic, but for a more experienced audience.

By understanding these filtering and sorting concepts, you will be able to extract specific data from your SQL databases in a targeted and organised way.

Joins

Joins are essential for combining data from several tables.

Common types of joins include INNER JOIN, LEFT JOIN, RIGHT JOIN and FULL JOIN, each offering specific methods for associating rows between different tables.

Example of a simple join:

SELECT customer.name, orders.date

FROM customers

INNER JOIN orders ON customers.customer_id = orders.customer_id;

Types of joins :

INNER JOIN: Returns the rows when the join condition is true in both tables.

LEFT JOIN (or LEFT OUTER JOIN): Returns all the rows in the left-hand table and the corresponding rows in the right-hand table.

RIGHT JOIN (or RIGHT OUTER JOIN): The opposite of LEFT JOIN.

FULL JOIN (or FULL OUTER JOIN): Returns all rows when the join condition is true in one of the two tables.

Constraints for data integrity and Indexes to optimise performance

Constraints play a crucial role in guaranteeing data integrity. Primary keys ensure that each record in a table is unique, while foreign keys establish links between different tables. Uniqueness constraints ensure that no duplicate values are allowed in a specified column.

Indexes are data structures that improve query performance by speeding up data searches. Creating an index on a column makes searching easier, but it is essential to use them wisely, as they can also increase the size of the database.

Conclusion

SQL is a powerful and universal tool for working with relational databases. Understanding its fundamentals enables developers and data analysts to interact effectively with database management systems, making it easier to manipulate and retrieve crucial information. Whether for simple tasks or more complex operations, SQL remains an essential part of data management.

It offers a range of tools for interacting with relational databases in a powerful and flexible way. By understanding these basic concepts, you’ll be better equipped to effectively manipulate data, create custom reports and answer complex questions from large datasets. Whether you’re a developer, data analyst or database administrator, mastering SQL is an invaluable asset in the world of data management.

Data Warehouses vs Data Lakes: a comparative dive into the Tech World

In the ever-evolving world of technology, two terms have been making waves: Data Warehouses and Data Lakes. Both are powerful tools for data storage and analysis, but they serve different purposes and have unique strengths and weaknesses. Let’s dive into the world of data and explore these two tech giants.

Data Warehouses have been around for a while, providing a structured and organized way to store data. They are like a well-organized library, where each book (data) has its place. Recent advancements have made them even more efficient. The convergence of data lakes and data warehouses, for instance, has led to a more unified approach to data storage and analysis. This means less data movement and more efficiency – a win-win!

Moreover, the integration of machine learning models and AI capabilities has automated data analysis, providing more advanced insights. Imagine having a personal librarian who not only knows where every book is but can also predict what book you’ll need next!

However, every rose has its thorns. Data warehouses can be complex and costly to set up and maintain. They may also struggle with unstructured data or real-time data processing. But they shine when there is a need for structured, historical data for reporting and analysis, or when data from different sources needs to be integrated and consistent.

On the other hand, Data Lakes are like a vast ocean of raw, unstructured data. They are flexible and scalable, thanks to the development of the Data Mesh. This allows for a more distributed approach to data storage and analysis. Plus, the increasing use of machine learning and AI can automate data analysis, providing more advanced insights.

However, without proper management, data lakes can become « data swamps », with data becoming disorganized and difficult to find and use. Data ingestion and integration can also be time-consuming and complex. But they are the go-to choice when there is a need for storing large volumes of raw, unstructured data, or when real-time or near-real-time data processing is required.

Mastering your Data: the essence and impact of the data catalogue

In today’s hyper-connected world, where data is seen as the new gold, knowing how to manage and exploit it is essential for businesses wishing to make informed decisions and remain competitive. The concept of the data catalogue is emerging as a key response to this challenge, offering a compass in the vast and often tumultuous ocean of data.

This article aims to shed light on the challenges and benefits of data catalogues, modern libraries where metadata is not just stored, but made comprehensible and accessible. Through the automation of metadata documentation and the implementation of collaborative data governance, data catalogues are transforming the way organisations access, understand and use their valuable information.

 

By facilitating the discovery and sharing of trusted data, they enable organisations to navigate confidently towards a truly data-driven strategy.

But also...

A data catalogue is a centralised tool designed to effectively manage data within an organisation. According to Gartner, it maintains an inventory of active data by facilitating its discovery, description and organisation.

The basic analogy would be to say that it is a directory, where readers find the information they need about books and where they are: title, author, summary, edition and the opinions of other readers.

The aim of a data catalogue is to make data governance collaborative, by improving accessibility, accuracy and relevance of data for the business. It supports data confidentiality and regulatory compliance through intelligent data lineage tracing and compliance monitoring.

Here are 5 reasons for your data teams to use a data catalogue:

Data analysts / Business analysts

They use the data catalogue to find and understand the data they need for their analyses. This enables them to access relevant data quickly, understand its context and guarantee its quality and reliability for reporting and analysis.

 

Data Scientists

The data catalogue is essential for locating the datasets they need for their machine learning and artificial intelligence models. It also makes it easier to understand the metadata (where the data comes from and the transformations it has undergone), which is vital for data pre-processing.

 

Data Stewards

They are responsible for data quality, availability and governance. They use the data catalogue to document metadata, manage data standards, and monitor compliance and the use of data within the organisation.

 

Compliance and security managers

The data catalogue helps them to ensure that data is managed and used in accordance with current regulations, such as the GDPR for the protection of personal data. They can use it to track access to sensitive data and audit data use.

 

Data architects and engineers

These technicians use the data catalogue to design and maintain the data infrastructure. It provides them with an overview of the data available, its structure and its interrelationships, making it easier to optimise the data architecture and integrate new data sources.

It’s important to note that business users are not left out of this tool either. Although they are not technical users, they benefit from the data catalogue to access the information and insights they need to make decisions. The directory enables them to find relevant data easily, without the need for in-depth technical knowledge.

Key points

A data catalogue is used to:

 

  • Improve data discovery and access

 

  • Strengthen data governance

 

  • Improve data quality and reliability

 

  • Facilitate collaboration between teams

 

  • Optimise the use of data resources
