Lecture #2 - Software Architecture

Synopsis:

Lecture Content:

1. The Syllabus describes topics to be covered, reading material for you to digest before coming to class, and due dates for the assigned projects.

2. Schedule Notes:

   • Help Session this Friday, August 31st at 9:00am in CST 4-201.
   • No class on Monday - it's Labor Day.

3. Packages:

   Building Blocks for Large Systems:

   • Package Structure Matters! Example: BlockingQueue Package, Example: Code Analyzer Folder
   • System Packages, Software Structure
     Packages are the building blocks for a complex architecture.
   • Incremental Development
     A rational way of building large, complex software systems.

4. O.K., Now What?

   Start where you are, use what you have, do what you can.

5. Projects:

   What projects are required?

   • Project #1, Grade Sheet, doc
     Operational Concept Document for Lexical Scanner
   • Project #2, Grade Sheet, doc
     Lexical Scanner Implementation
   • Project #3, Grade Sheet, doc
     Type-based Package Dependency Analysis
   • Project #4, Grade Sheet, doc
     Remote Package Dependency Analysis
     
   All code will be developed using C# and the .Net Framework Class Library with Visual Studio 2017. How will your submissions be evaluated? OCD grade sheet, Code grade sheet Grading Policy

6. Software Architecture:

   Motivation, Discussion, and Examples:

   • Problem with Dependencies   More
     
   • Components are Building Blocks
     Motivation for a lot of what we do in this course.
   • Software Architecture and the Operational Concept Document (OCD), pptx
     
   • Operational Concept Document (OCD) Survival Guide docx
   • UML-Diagrams.htm, UML Diagrams Presentation, pptx
     UML - uml-diagrams.org, UML - Embarcadero.com
     The Universal Modeling Language is used to describe software with means other than code. You will use these diagramming techniques in your OCD.
   • Example Diagrams:
     Package Diagram, Activity Diagram, Simple Class Diagram, Detailed Class Diagram, Sequence Diagram, Structure Chart, State Diagram, Data Flow Diagram, Ad Hoc Diagram
   • Project Center Use Cases
     This presentation was developed for a Software Studio project. It gives you a good idea of the kind of analyses you need for an OCD.
   • Getting Started!
   • Study Guide - OCD   Has links to sample documents.
   • Writing with Style, Third Edition, John Trimble, Prentice-Hall, 2010, ISBN 978-0205028801

7. C# versus C++

8. C# Code Examples and Tutorials:

   • Getting Started with C#
   • C# code examples
   • C# Samples from Microsoft
   • tutorialspoint
   • C# Station
   • CSharp Computing
   • homeandlearn
   • Univ of Linz
   • Jaggersoft

9. Lecture Take-away:

   The most important things covered today were:
   • Packages:   Package Structure Matters!, Example: BlockingQueue Package
   • What an architecture document covers.
   • The specifics of what a Concept Document covers - a subset of an architectural description.
   • The UML diagrams - Package and Activity diagrams are the most useful for OCDs.
   Next time we will discuss Project #1 and Project #2 so please review this weekend.
