Chapter 6, Problem 3RQ
Program Plan Intro
Normalization:
The process used to minimize data redundancy and dependency in a relational
- The database table is divided into two or more tables and defines the relationship between those tables.
- If the modifications, deletion or updates occur in one table, the other tables in database get updated by just propagating it.
- In a relational database, the tables with no redundant data and less null values are considered as efficient table.
- This is because, having redundant data and more null values increases the storage space and wastage of memory is imminent.
- Null values cause a problem for data integrity and produces more error in the database.
- If the wasted storage space and null values which cause data integrity hazards are minimized, a highly optimized relational database can be designed.
- The project team should consider using normalization when designing the database, which is the best source to optimize data storage efficiently; this is because, it reduces the data storage space and provides data integrity.
- There are three types of normal forms.
- First normal form (1NF)
- Second normal form (2NF)
- Third normal form (3NF)

I cannot program smart home automation rules from my device using a computer or phone, and I would like to know how to properly connect devices such as switches and sensors together ?
Cisco Packet Tracer
1. Smart Home Automation:o Connect a temperature sensor and a fan to a home gateway.o Configure the home gateway so that the fan is activated when the temperature exceedsa set threshold (e.g., 30°C).2. WiFi Network Configuration:o Set up a wireless LAN with a unique SSID.o Enable WPA2 encryption to secure the WiFi network.o Implement MAC address filtering to allow only specific clients to connect.3. WLC Configuration:o Deploy at least two wireless access points connected to a Wireless LAN Controller(WLC).o Configure the WLC to manage the APs, broadcast the configured SSID, and applyconsistent security settings across all APs.
