Week 2 tyoes of databases and ERD 2020

  1. 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. 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
  3. 3. Warm Up Listen to this video offline On line motivating programmers
  4. 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. 5. Database concepts Field, record, primary key, foreign key Types of relationships : One To One , One To Many Many To Many 5
  6. 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 6 http://www.stemassiut.info prepared By Mr. Osama Ghandour
