  • You will do this homework in your first lab period (this week)
    • Make sure you have a JPEG picture of yourself (< 100k)
  • You’ll also take the course pretest during the lab
the course web page
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.

the main course topics
The Main Course Topics
  • 3-tier architectures
  • Data structures
  • Sorting and searching
  • Programming language concepts
  • Other hard-to-categorize topics
3 tier architecures
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
    • Model-View-Controller (MVC)
data structures
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
sorting and searching
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)
programming language concepts
Programming Language Concepts
  • Programming paradigms, including
    • Object-oriented
    • Procedural
    • Scripting
  • Overloading operators
  • Pointers
  • Dynamic memory and memory management
  • Abstract data types
other topics
Other Topics
  • Computational complexity
  • Recursion
  • Class libraries (STL)
  • Web technologies (HTML, PHP)
  • Debugging
  • Safe programming
laboratories
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.
laboratory topics subject to minor changes
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
