Effective data management and retrieval require databases and SQL (Structured Query Language). The following fundamentals can help you:
A database: What is it?
A database is a well-formatted, readily accessible, manageable, and updateable collection of structured data. They are employed for methodical information archiving and retrieval.
What is SQL?
A relational database management system (RDBMS) is a system that uses SQL, a standard programming language, to manage and query data. You can use it to build, edit, remove, and get data out of databases.
Crucial SQL Input Methods:
• SELECT: a database query that extracts data
• INSERT: Updates a table with new records.
• UPDATE: Updates records that already exist in a table.
• DELETE: Takes entries out of a table
• CREATE TABLE: Establishes a brand-new table.
• ALTER TABLE: Adjusts a table’s current structure.
• JOIN: Integrates information from two or more tables according to a shared column.
