tyoes of databases and ERD

1. Agenda
1- Warm up Listen to this video about motivating 5 min
3- ppt teacher demonstrate data bases and ERD 20 min
4-Students work practically in designing an
excel table as example od simple data base
related to their Capstone projet 15 min
5- Video about how we can using ERD in real life data
base projects 5 min
6- On line quiz about previous L.O. Networks 15 min
7- summary and refelection 5 min
8- Home work 5 min
2- ppt students demonstrate data bases and ERD 10 min

2. LO Students identufy Database and its
types. 2- Students identufy Entity Relational
Diagram (ERD) design Database. 3- Stutens
write code by using Structured Query
Language (SQL). 4- Students design simple
small-scale databases (contain some tables).
5- Students identufy database concepts (field,
record, primary key, foreign key and types of
relationships (OneToOne, OneToMany and
ManyToMany). 6- Students create
relationships between the tables. 7- Students
create query (view), reports. Lesson plan

4. Essential Question
3- What does "ERD" stand for?
2- What are Database types?
1-What is a data base ?
Database, any collection of data, or information,
that is specially organized for rapid search and
retrieval by a computer. Databases are structured
to facilitate the storage, retrieval, modification, and
deletion of data in conjunction with various data-
processing operations.

5. Database concepts
Field, record, primary key, foreign
key
Types of relationships :
One To One ,
One To Many
Many To Many

6. Types of Database Management
Systems
• Relational databases->Hierarchical databases
• SQL databases vs NoSQL databases
• NoSQL databases -> Graph & Document
databases
• Network databases.
• Relational databases vs Object-oriented
databases.
• Entity–relationship databases = ERD

20. Reflection
• What is your goal to accomplish in
next week end Using ERD ?
• Write one question you would like to
ask about today’s topic?

21. students create in small
groups a data base
related to their capstone
project .
Home work 1
+ =
C program
Arduino
Arduino hardware
controller
components of used recycled /
saved water system

22. Home Work 2
Discuss how to use
data bases in
different practical
real life or
capstone projects 22
