Study Notes
Relational Databases
- Store and provide access to related data points
- Based on the relational model, representing data in tables
- Advantages:
- Enforce data integrity through constraints like primary keys, foreign keys, and unique constraints
- Allow for complex and flexible queries using SQL
- Can handle large amounts of data and scale horizontally or vertically
- Offer robust security features like user authentication, authorization, and encryption
Enterprise Resource Planning (ERP)
- Integrate an organization's information into one overall system
- ERP modules:
Financial
- Manage financial information
Human Resources and Payroll
- Manage employee data and payroll
Order to Cash
- Manage sales and payment processes
Purchase to Pay
- Manage procurement and payment processes
Manufacturing
- Manage production and inventory
Project Management
- Manage projects and tasks
Customer Relationship Management
- Manage customer interactions and data
System Tools
- Manage system configurations and settings
- Advantages:
- Integrate organization's data and financial information
- Capture data once and reduce redundancy
- Improve management visibility and monitoring
- Enhance access controls and security
- Standardize business operating procedures
- Improve customer service and manufacturing efficiency
- Implement industry best practices
- Disadvantages:
- High costs
- Time-consuming implementation
- Disruptive changes to existing business processes
- Complexity and resistance to change
- Risk of losing competitive advantage due to standardized processes
Documentation of Flowchart
- Set of documents and models (narratives, data flow, models, flowcharts)
- Includes inputs, processes, storage, output, and controls
- Allows auditors to monitor business operations and information
Different Systems
- Document: Illustrates the flow of documents through an organization
- Program: Logical representation of system inputs, processes, and outputs
- System: Actual steps of the activity, detailed to represent the logical sequence
- Context: Highest level, showing inputs and outputs into the system
- Level 0: Shows all major activity steps of a system
- Level 1: Shows one major activity divided into sub-activities
