Outline

• History
• What quantum computing is and how it works
• Effects on society and ecommerce
• Encryption schemes not vulnerable to quantum
  computing algorithms
• Current state of quantum computing

Why a new Semantic language?

• UML does not easily cohabitate with ER and
  relational data models.
• However, Jason Wells believes he came up with a
  new semantic language that will make sharing
  between the different models easier.

UML ERs flaws

• It is hard to learn.
• When you need to model something that doesnt
  already have a specific design you usually end up
  putting UML comments in to explain it. These have
  a different syntax than the rest of the model and
  therefore arent conducive.
• 9 different diagrams with their own rules and
  looks, which arent easily combined.

5
UML ERs flaws

• ER diagrams and UML syntax dont combine very
  well.
• UML diagrams dont always express themselves
  graphically in the structure of the diagram.

Semantic Object Language (SOL)

• It would be better and easier to show your UML
  and ER diagrams with a semantic network knowledge
  representation (SOL) to give a clearer more
  meaningful meaning.
• This is a tool to help you show the information
  you would typically show in UML

7
SOL

• To design it you create concepts for each class.
• Using the predefined relations with the SOL class
  ontology you can relate the fields, methods, and
  attributes to their classes.
• Each concept are joined by all named relations.
• Associations connect all classes
• You can use any additional concepts and
  relations, to produce the semantic network.

New Design Methodology

• SOL much quicker than UML to learn and create.
• You have to learn such things in UML as a dotted
  line arrow with an open arrowhead means
  realization, signifying a class implementing an
  interface.
• In SOL just need one arrow saying realized by and
  one realizes.

12

• Only basic elements needed concepts, relations,
  instances, etc.
• You can also show the design before you have all
  the errors worked out.
• All UML diagrams can be shown using one visual
  syntax.
• All these and ER diagrams can be represented
  using a common semantic network, which means one
  OOD model can be used for the entire design.

SOL

• Paper clip represents Knowledge Objects in which
  anything can be added. To give further
  understanding and meaning.
• This is another way to represent Semantic Object
  Models.
