7. jgs 564 00000110 Homework Read: § Programming in the Large vs Programming in the Small F. DeRemer International Conference on Reliable Software April 1975 § Teaching Object-Oriented Thinking Kent Beck (JUnit 👀) International conference on OOPSLA October 1989
8. jgs 564 00000110 Timeline 1971 Wirth 1972 Parnas 1975 DeRemer 1989 Beck Programming in the Large OO Thinking Stepwise refinement Information Hiding 1997 UML
9. jgs 564 00000110 Programming in the large (1975) Programming in the Large vs Programming in the Small F. DeRemer International Conference on Reliable Software April 1975 50 most influential and technically excellent publications programming languages ACM
10. jgs 564 00000110 Programming in the large (1975) § High-cohesion and loose-coupling § Programming versus Structuring § (Develop) Many small programs(modules) written by different people. § (Architecture) Structuring a large collection of modules to form a "system" § Care for the trees without lose sight of the forest § Changes become difficult if operates across module boundaries § Programming in the large involves setting up modules that will not need altering in the event of probable changes.
11. jgs 564 00000110 Programming in the large (1975) § Top-down. § Bottom-up. § One level at a time. § Vertical / Horizontal § Linking § Composition § Decomposition § Accessibility (public, private) § Hierarchy
12. jgs 564 00000110 Teaching Object-Oriented Thinking (1989) Teaching Object-Oriented Thinking Kent Beck International conference on OOPSLA 1989 Creator of eXtreme programming and Creator of Unit Testing Framework (JUnit for Java with Erich Gamma) ACM
13. jgs 564 00000110 Teaching Object-Oriented Thinking (1989) Class name, responsibilities, and collaborators • Designs can be characterized at an abstract level as having processes, data flows, and data stores, regardless of implementation language or operating environment. • A Diagram for Object-Oriented Programs Cunningham, W. and Beck, K.: OOPSLA, 1986.
