### Lesson Breakdown
#### **Introduction (5 minutes)**
1. **Greeting and Attendance (1 minute)**
2. **Icebreaker/Hook (2 minutes)**: Ask students if they have ever booked a library book, checked their grades online, or used social media. Briefly discuss how databases are involved in these activities.
3. **Objectives Review (2 minutes)**: Outline the lesson objectives on the board or screen.
#### **Lecture/Instructor Led Activity (20 minutes)**
1. **Definition of a Database (3 minutes)**
- Explain what a database is: a structured collection of data that can be easily accessed, managed, and updated.
2. **Types of Databases (5 minutes)**
- Relational Databases: Organize data into tables which can be linked by common fields (e.g., SQL databases).
- NoSQL Databases: Non-tabular databases that store data differently (e.g., MongoDB, Cassandra).
- Hierarchical Databases: Organize data in a tree-like structure (e.g., IBM's IMS).
- Network Databases: Data is organized in a graph structure allowing more flexible relationships.
3. **Components of a Database (7 minutes)**
- Tables: Collections of related data entries.
- Fields: Columns in a table, each field contains data about a specific property.
- Records: Rows in a table, each record is a data set that represents an item.
- Queries: Tools to fetch data based on specific criteria.
- Forms: Interfaces for data entry.
- Reports: Summarized data outputs.
4. **DBMS (Database Management System) (5 minutes)**
- Functions of a DBMS: Data storage, Data retrieval, Data update, Administration.
- Examples of DBMS: Microsoft Access, MySQL, Oracle, PostgreSQL.
#### **Hands-On Activity (15 minutes)**
1. **Introduction to the Software (2 minutes)**
- Briefly explain the database software to be used (e.g., Microsoft Access).
2. **Creating a Simple Database (13 minutes)**
- Open the software and demonstrate creating a new database.
- Guide students to create a table with fields like: StudentID, Name, Age, Class.
- Enter at least 5 records.
- Show how to save and open the database.
#### **Review and Q&A (5 minutes)**
- Recap the key points covered in the lesson.
- Ask if students have any questions regarding the lesson.
- Summarize by emphasizing the importance of databases in various fields.
#### **Assignment (5 minutes)**
- Assign students to think of a simple database they would like to create (e.g., a database for their favorite books). They should plan the fields and records they would need, to be implemented in the next class.
#### **Closure**
- Thank the students for their attention and participation.
- Provide a brief overview of what the next lesson will cover.

### Assessment:
- Participation during hands-on activity.
- Questions asked and answered during Q&A.
- Quality of planned databases for the assignment.
### Follow-Up:
- Provide additional resources or websites for further reading on databases.
- Plan for a subsequent lesson where students will refine and present their databases.
