Object Oriented Analysis
Object Oriented Analysis
System modeling = Functional modeling + Object modeling + Dynamic modeling
Functional modeling = Use cases
Object modeling =class diagrams
Class diagram:
Describe the static structure of the system: Objects, attributes, associations
Remember:
We use models
To abstract away from details in the reality, so we can draw complicated conclusions in the reality with simple steps in the model

Cryptography is the science of using mathematics to encrypt and decrypt data.
Cryptography enables you to store sensitive information or transmit it across insecure networks (like the Internet) so that it cannot be read by anyone except the intended recipient.
