Methodology and Instructions:

• Installation Steps:
  • Download PostgreSQL from the official site.
  • Follow the installation prompts and set up the database.
  • Use PG Admin for a graphical interface or command line for SQL queries.
• Basic SQL Commands:
  • CREATE a database: CREATE DATABASE dbname;
  • CREATE a table:

    CREATE TABLE tablename (
                        column1 datatype,
                        column2 datatype,
                        ...
                    );

  • INSERT data:

    INSERT INTO tablename (column1, column2) VALUES (value1, value2);

  • Query data:

    SELECT * FROM tablename;

• Join Tables:
  • Use INNER JOIN to retrieve matching records:

    SELECT * FROM table1 INNER JOIN table2 ON table1.id = table2.id;

• Using Aggregate Functions:
  • Count records: SELECT COUNT(*) FROM tablename;
  • Sum values: SELECT SUM(column) FROM tablename;
• Defining Relationships:
  • Establish foreign keys to maintain relationships between tables.
