3. Your First Assignment Homework 0: click on “Assignments” on the main course page You will do this homework in your first lab period (this week) or some time before Aug 29 –Make sure you have a JPEG picture of yourself (< 100k) You’ll take the course pretest this week (due Aug 29)

4. The Course Web Page On the course web page you will find –Course details –Daily schedule (subject to change) –Assignments –Laboratory information –Grading scale and gradebook –My policies, expectations, etc. –Lecture notes and sample code –Useful links

5. The Main Course Topics 3-tier architectures Data structures Sorting and searching Programming language concepts Other hard-to-categorize topics

6. 3-Tier Architecures A 3-tier architecture is one which has –A database back-end –A middle tier which contains most of the logic –A GUI front-end Related to this we will learn about –Relational database definition –Relational database design –Defining and manipulating relational databases with SQL –Connecting to a database from an application

7. Data Structures We will learn about –Linked lists –Stacks –Queues –Binary Trees We will discuss two main methods of implementing common data structures –Array based –Pointer based

8. Sorting and Searching Related to searching, we will learn about –Sequential Search –Binary Search –Hashing We will discuss the following sorting algorithms –Selection sort –Insertion sort –Bubble sort –Quick sort –Merge sort –Heap sort (time permitting)

9. Programming Language Concepts Programming paradigms, including –Object-oriented –Procedural –Scripting Overloading operators Pointers Dynamic memory and memory management Abstract data types

10. Other Topics Computational complexity Recursion Class libraries (STL) Web technologies (HTML, PHP) Debugging Safe programming

11. Laboratories The purpose of the laboratories is to –Give you hands-on experience using the topics from lecture and the textbooks –Teach you practical skills related to the course concepts –Expose you to new languages, libraries, operating systems, software tools, etc.

12. Laboratory Topics (subject to minor changes) New Operating System: UNIX New Object-Oriented Language: C++ New Debugger: gdb New Concept: Overloading Operators New Concept: Memory Management New Concept: Templates New Concept: Safe Programming Database Query Language: SQL Hypertext Markup Language: HTML Scripting Language: PHP
