SQL Basics — Tables, Views, and Stored Procedures
SQL is crucial for data analysts because it provides a powerful and standardized way to access, manipulate, and analyze data stored in relational databases.
With SQL, data analysts can write queries to extract relevant information, perform complex joins and aggregations, and gain valuable insights from large datasets.
When working with data, SQL is an indispensable tool and this article will explore some of its basic concepts: Tables, Views, and Stored Procedures.
Tables
Tables are fundamental database objects that store data in a structured format, they represent the core of the database, and all data is ultimately stored in tables.
A table has a well-defined schema that determines the columns, data types, and constraints of the data it can store. It follows a fixed structure that must be defined when the table is created. Tables are the primary means of storing data in a database, ensuring data persistence even after the database system is shut down.
