Answer 1

The given code creates three tables in a database: BRIDAL_PARTY, EMPLOYEE, and VENUE. Each table has its own set of columns with specified data types and constraints.

Step-by-step explanation:

The given code snippet is written in SQL and creates three tables: BRIDAL_PARTY, EMPLOYEE, and VENUE. Each table has a unique set of columns and their respective data types.

The BRIDAL_PARTY table has columns for EMAIL (primary key), F_NAME, L_NAME, GENDER, DOB (date of birth), BRIDAL_ADDRESS, and MOBILE.

The EMPLOYEE table has columns for ID (primary key), NAME_FIRST, NAME_LAST, EMPLOYMENT_DATE, ADDRESS, and JOB_DESCRIPTION.

The VENUE table has columns for ID (primary key), FIRST_NAME, V_LOCATION, V_ADDRESS, MAX_CAPACITY, and V_DESCRIPTION.

The primary key constraint is used to uniquely identify each row in a table. In this case, the EMAIL column in the BRIDAL_PARTY table and the ID column in the EMPLOYEE and VENUE tables are specified as primary keys.

The specified data types for the columns include VARCHAR (variable-length character string), DATE (date value), and INTEGER (whole number).

By creating these tables with the specified columns and data types, you can store and manage data related to bridal party members, employees, and venues in a database.

These tables can be used to store information such as names, addresses, contact details, and other relevant data for efficient organization and retrieval.
