Study Notes

Cloud Computing

Cloud computing is a technology enabling individuals and businesses to access and use computing resources.
It delivers computing services (e.g., servers, storage, databases) over the internet.
Key characteristics include on-demand self-service, broad network access, resource pooling, and measured service.
Cloud computing offers faster innovation, flexible resources, and economies of scale.

Types of Cloud Computing Services

Software as a Service (SaaS): A crucial service type.
- Examples include Google Workspace, Microsoft 365, Salesforce, and Dropbox.
Platform as a Service (PaaS): Another important service type.
- Examples are Google App Engine, Microsoft Azure, and AWS Elastic Beanstalk.
Infrastructure as a Service (IaaS): A vital service type.
- Examples include Amazon EC2, Microsoft Azure Virtual Machines, and Google Compute Engine.

Benefits of Cloud Computing

Cost-effectiveness: The pay-per-use model reduces upfront infrastructure costs.
Scalability and flexibility: Easily adapts to changing demands.
Reliability and availability: High availability and disaster recovery options.
Increased productivity and efficiency: Streamlines operations and provides anywhere access to data.

Microsoft Access Revision Notes

What is a Database?

An organized collection of related data.
Stores information systematically (e.g., student records, inventory).
Microsoft Access is a database management system (DBMS). This combines a relational database engine with a user-friendly graphical interface.

Why use a Database?

Efficient data storage and retrieval.
Data integrity and consistency.
Data sharing and collaboration.
Powerful analysis capabilities.

Key Features of Microsoft Access

Highly organized and structured data.
Links data points (e.g., customer orders).
Connects to other databases and applications.

Key Components of a Microsoft Access Database

Tables: Stores data in rows and columns.
Queries: Extracts and manipulates data from tables.
Forms: Simplifies data entry and display.
Reports: Summarizes and presents data.
Macros: Automates tasks to improve functionality.

Designing a Database

Planning Phase:
- Determines database purpose.
- Identifies entities and attributes.
- Defines relationships between entities.
Creating Tables:
- Designs table structure with appropriate fields (with specific data types).
- Establishes primary and foreign keys to link tables (ensuring data uniqueness).
- Data Types: (Short Text, Number, Date/Time, Currency, AutoNumber, Yes/No, Attachment, Calculated).
Entering and Editing Data:
- Uses forms or datasheet view to enter and modify data.
- Validates data to ensure accuracy.
Filtering and Sorting Data:
- Uses filters to display specific data.
- Sorts data.
Creating and Running Queries:
- Designs queries using the Query Design Grid.
- Combines criteria using operators (AND, OR, NOT).
- Performs calculations (sum, average, count).
Creating Forms and Reports:
- Designs custom forms and reports.
- Adds controls (text boxes, labels, buttons).
Types of Forms:
- Single: Displays one record at a time.
- Continuous: Displays multiple records.
- Datasheet: Mimics the table view.
- Split: Combines single and datasheet views.
Report Design:
- Selects or constructs custom reports.
Queries:
- Select Query: Extracts specific pieces of data.
- Action Queries: Updates or deletes database records.
- Parameter Queries: Uses user input for dynamic results.
- Aggregate Queries: Summarises data using aggregate functions (e.g., SUM, AVG).
Reports:
- Summarizes and presents data.
- Provides formatted output for printing.
Relationships:
- Normalization: Organizes data to reduce redundancy for efficient storage and access.
- Types of Relationships: One-to-One, One-to-Many, Many-to-Many.
