Hey im doing a my SQL project on Project Proposal: Database for Electricity Usage in the Houston Area

use Project Proposal: Database for Electricity Usage in the Houston Area

Name: Houston Electricity Usage Database

Purpose: This database will track and manage electricity consumption across multiple counties in the Houston area. The goal is to store data on energy usage patterns, customer demographics, and power grid performance. This information will be useful for utility companies to analyze usage trends, optimize power distribution, and plan for future demand. Additionally, it will assist government agencies and policymakers in making data$-$driven decisions regarding energy policies, sustainability efforts, and infrastructure upgrades.

This structure will help analyze electricity usage patterns across different counties, such as Harris, Montgomery, and Fort Bend, and assist in improving energy efficiency.

In Phase $3,$ you will refine your database by ensuring that it adheres to $3$rd Normal Form $(3$NF$),$ which eliminates redundancy and ensures data integrity. Here$$s what you need to do:

First, make sure each table is in $3$NF$.$ This means organizing your tables so that there are no repeating groups or unnecessary dependencies between columns. Add new entities, such as transition tables, if necessary, to achieve this.

Next, create physical diagrams. These diagrams build on your logical diagrams but now include all attributes for each entity, their data types, sizes, and identification of keys $($primary and foreign$).$

Finally, create a data dictionary. This is a descriptive list of all tables in your database, detailing each entity, its attributes, and how the data is organized.

These steps will help you finalize the structure of your database with proper organization and documentation.

Phase $3$: ERD in $3$NF$,$ DD

Deliverable

Each table is in $3$NF

Add new entity as needed $($such as transition tables$)$

Physical diagrams: all attributes in all entities have datatype, and if they are keys

Data Dictionary: Description of all tables in the DB

Note: Physical diagrams are the result of the evolution of logical diagram. It has all items in logical diagram, plus all attributes have types, size, & identified if Key$2$ Attempts Allowed

heres a pic of my diagram so far how do i step by step do the next part im confused Customer Information Table:

$?$ Customer$\_$ID INT

$$ First$\_$Name VARCHAR$(50)$

Last$\_$Name VARCHAR$(50)$

$\frac{?}{{?}_{\frac{?}{?}}}$ Address VARCHAR$(100)$

City VARCHAR$(50)$

$$ State CHAR$(2)$

$$ Zip$\_$Code VARCHAR$(10)$

$\frac{?}{{?}_{\frac{?}{?}}}$ County$\_$ID INT

Billing Information Table:

$$ Billing$\_$ID INT

Customer$\_$ID INT

Billing$\_$Date DATE

Amount$\_$Due DECIMAL$(10,2$
