Project Resource Management: Cost, Risk, and Quality
Project Resource Considerations
Projects always involve trade-offs between resources, schedule, human resources, costs, quality, and scope. Resources are limited, and Project Managers must recognize these limitations to avoid overpromising. People often constitute a large portion of the total project cost. Managing people is the most challenging aspect of a project. Resource availability, especially human resources, is a major constraint.

Week 10: Vector Databases, Cloud Architecture, and Operations
Introduction: Vector embeddings are lists of numbers, a core concept in machine learning. They are central to many applications, including:
- Natural Language Processing (NLP)
- Recommendation systems
- Search algorithms
Examples of real-world systems that rely on embeddings:
- Recommendation engines
- Voice assistants
- Language translators
What Are Vector Embeddings?
Vector embeddings are lists of numbers representing complex data structures. They allow

The Social Questions
The Industrial Revolution saw Great Britain, the world’s largest power, and other nations create a proletariat around factories. The economic ideas of Adam Smith and David Ricardo supported this revolution. Their doctrines stated:
- Economic laws are natural and cannot be judged as good or evil.
- Open competition regulates supply and demand.
- The state should not intervene in the economy.
This caused enormous inequalities. Owners controlled the means of production, while workers faced

What are LANs?
A Local Area Network (LAN) is a communication system that connects computers at high speed within a limited area, usually within the same building. A LAN consists of network hardware and software, providing the ability to share resources, including software, information, hard drives, directories, and printers.
What is a MAN?
A Metropolitan Area Network (MAN) is used to interconnect LANs. They are not geographically limited in size and often need to interface with special hardware, telephone

Week 7: NoSQL
What is Big Data?
Scale – Dimensions
- Workload – Number of concurrent sessions and operations
- Operation mix (create, read, update, delete)
- Read – query mix
- Generally, each system use case represents a distinct workload
- Data Sets – Volume, Velocity, Variety
- Number of records
- Record size
- Record structure (e.g., sparse records)
- Homogeneity/heterogeneity of structure/schema
- Elasticity
- Runtime peaks and valleys – how frequently, how quickly, how much
Scalability
“Scalability is the ability
