Defining SQL   

SQL, or Structured Query Language, is a powerful and standardised programming language used for managing, manipulating, and retrieving data from relational database systems. Developed in the early 1970s, SQL serves as a bridge between users and databases, enabling efficient communication with databases by executing queries and commands. 

SQL operates on relational databases, which store data in structured tables with rows and columns. Users can interact with these databases through basic structure of SQL queries to perform various tasks, such as creating, modifying, and deleting tables, as well as inserting, updating, and querying data.

SQL commands include SELECT (used to retrieve data), INSERT (for adding new data), UPDATE (for modifying existing data), and DELETE (for removing data). SQL also provides capabilities for defining and managing database structures, like indexes, constraints, and views. SQL has become essential for businesses, developers, and data professionals to effectively work with relational databases, ensuring data integrity and facilitating data-driven decision-making.

The importance of SQL  

SQL helps Database Administrators and Engineers to interface with information systems seamlessly. The integration services offered by SQL Server are beneficial for large-scale companies holding a massive volume of data. These companies can reduce their workload by efficiently storing and collecting data from their departments.  

The services of SQL can significantly simplify these operations. The consistent practice of SQL operations on databases for different real-world applications benefits users of all competency levels. SQL practices span multiple industries like healthcare, finance, e-commerce and so on. Beginners will improve their logical and analytical thinking skills in real-world scenarios and improve their employability in the job market for SQL-based designations. 

SQL Projects for Beginners

Below is a curated list of SQL Projects that Beginners can practice to improve their skill levels:
