cit597 About This Course Jan 14 2019 CIT597 The formal title of this course is Programming Languages Techniques III A better title would be Web technologies Some of these technologies are specific to Java Most of the technologies are language independent This course however uses Java Prerequisite CIT594 or equivalent proficiency in Java Translation you had better already be a pretty good Java programmer 2 The network is the computer The explosive growth of the Web has greatly changed the face of computing Before we wrote programs under these assumptions We could use whatever language was convenient We could write programs for the computer we happened to have available at the moment We could design our own data formats and database schema We did not have to interact with the rest of the world Today all of these assumptions are wrong Sun s slogan The network is the computer is becoming true Platform independence is no longer a luxury but a necessity There is a large and growing need for information interchange 3 Platform independence The Internet has become extremely popular It connects millions of computers together These computers run all kinds of programs with all kinds of operating systems Interoperability of programs and data has become a serious issue There are two possible solutions Microsoft s preferred solution Force everyone to use Windows Much of Microsoft s software is designed with this end in mind If this happens it will not happen quickly Develop platform independent languages and systems This is what all the other software developers including Sun Microsystems the creator of Java are working on 4 Java HTML XML etc Java is the most platform independent language we have HTML is not as feature rich as MS Word but it nevertheless does a pretty good job We will look at ways to process XML from Java SQL is the most widely accepted database language HTML is the language of the Web Most software documentation these days is distributed in HTML PDF Adobe s Portable Document Format or plain text We will look at ways to create HTML from Java XML is a platform independent way of describing data This is one of the reasons for its popularity there are many others We will look at ways to access SQL databases from Java Client server architecture is used to communicate across the Web We will look at creating server side and client side applications 5 Some technologies we may cover HTML HTML Forms JavaScript XHTML CSS Ajax Java servlets JSP Perl PHP XML DTD XML Schemas Java SAX RELAX NG DOM JAXP Java Java JDBC But underneath HTTP TCP IP maybe Sockets RMI SQL Apache Tomcat Ruby Rails XSL XSLT XPath CSS 6 Software Most of the necessary software will be installed in the Moore 207 lab I strongly encourage you to install the software on your own computer The basic software you need is Java 6 Firefox 3 EasyEclipse for LAMP XAMPP Tomcat and a decent text editor such as jEdit or Notepad Other software will be recommended as needed The newest versions of all this software are freely available on the Web I avoid proprietary Windows only software I can t provide a lot of help with installation 7 Textbook The textbook is Programming the World Wide Web 4th Edition by Robert W Sebesta This is unfortunately a fairly expensive book about 90 but it fits this course very well Like my course this book is broad but shallow that is it covers a great many topics but none of them in any depth If you are seriously broke the Web is full of great and some not so great tutorials and specifications I will provides some links to these but You should be able to find this kind of information for yourself 8 Assignments We will have approximately one assignment per week Assignments will frequently build on previous assignments Assignments may say something like plus five features not covered in class This is to make sure you explore the resources available to you Note To make it practical to grade your assignments it is your responsibility to point out these extra features Appearance and content will be factors in grading Late policy 5 off for each day late Assignments will be due by midnight 9 Examinations We will have a short quiz each Wednesday Quizzes will concentrate on recently covered material but may include earlier material if appropriate Quizzes may include material that was not covered in class Your lowest quiz grade will be dropped There will be no final exam Assignments and examinations will be weighted as follows 50 assignments 50 quizzes Grades will be curved 90 or any other number is not necessarily an A 10 Extra credit I will not in general provide specific extra credit assignments Small amounts of extra credit will be given for helping to improve this class for example Finding new Web sites that I think are really useful just finding relevant Web sites is easy there are thousands Pointing out serious problems in my assignments early enough to help others I may allow significant extra credit for a project of your own devising if you first get me to agree and then do a good job on it Extra credit will be used to adjust grades upward after they have been calculated for the entire class 11 Rules You may You may not discuss the assignments with one another help others debug their work use without attribution anything I post to the Web share code with anyone but your assigned partner if any copy another s code or allow your code to be copied lend your code to someone else or leave it lying around where someone else may copy it use any code from textbooks or the Web without my permission If you think you may have accidentally broken a rule come and talk to me about it 12 The End I know Karate Kung Fu and 47 other dangerous words Source unknown 13
