Fall CIS 764 Database Systems Engineering L3: Two Assignments Relating to J2EE

Fall CIS 764 Database Systems Engineering L3: Two Assignments : 0. Set up a homeworks web site and directory (with obscure access) and send the link (to help instructor keep track of homeworks). 1. Construct a conceptual graph (in the form of a UML object / class model) for some major words of the J2EE model (to practice UML, UML tools, and to better know J2EE model). 2a. Download + install (or use the version in the CIS labs) Oracle JDeveloper (a J2EE development IDE) and post the small Swing-Hello-”name” program (to begin familiarity with JDev). … details follow.

Fall CIS 764 Database Systems Engineering Your homework submission web site and directory: (Prefer to install this folder on CIS machines ….faster for grading): Some_folder: <<< perhaps not in your 764 directory Index.html <<< without ref to the homeworks file Homework_folder (perhaps with an obscure name) Index.html <<< page with links to homework items homework_items <<< best as html pages or small jpgs the link: … as live link, absolute, not relative link.

Fall CIS 764 Database Systems Engineering Index.html: Homework for Bill Hankley <<< your name (so not credited to wrong person) Week: Item: <<< the week you posted the work 2 Conceptual GraphConceptual Graph (comments if needed) 2 Hello app using JDev linklink 3 Discussion of tables errors link ….link … relatively small submissions … include your name within each document (and key images). … remember.. Each page should have a title. … simple black on white for text … perhaps also send an (w link), when you post

Fall CIS 764 Database Systems Engineering Background … what is a conceptual graph (CG): … a semantic model for the meaning of words … … words “characterized” by attributes and relations. … based on work by John Sowa ( ) …. can be represented in visual form ( )

Fall CIS 764 Database Systems Engineering In a more simple form, a CG can be viewed as a UML object model (specific words) or a UML class model (kinds, without distinction of instances) or an ER data model where words are instances of various kinds words are objects / entities words may have attributes and relationships are explicitly named. <<<< Verbs (and other kinds) have binary (or higher relations); Nouns typically have unary relations with other nouns. Most key words for J2EE can be viewed as nouns.

Fall CIS 764 Database Systems Engineering CG as a UML object model:

Fall CIS 764 Database Systems Engineering Second homework: (a) review J2EE Tutorial or equivalent (b) build a UML conceptual graph of some number of the terms (related to this course) (c) post CG as UML object / class model as an machine generated image (watch for relations, aggregation, composition) “grading” will be “yes/no” evaluation (sample solutions will be discussed in later class)

Fall CIS 764 Database Systems Engineering OK to hand draw and print and scan draft diagram; but use some UML tool for final version: e.g. JDeveloper does UML class models (but not sequence models  ) I have used Visual Paradigm (Community version). What UML tool do you recommend? If you have a strong recommendation, please send . (I will report views to the class.)

10 CIS 764 Database Systems Engineering Preparation for homework: find, download and install Oracle JDeveloper or browse the Oracle site, but use JDev installed in CIS labs. (Version worked in 2007 newer version is 11g … I have not tried it yet) Why? will use JDev for Oracle on-line tutorials.  often the Oracle tutorials will not work exactly with newer versions !

Fall CIS 764 Database Systems Engineering W hat is JDev ? free, IDE, Java based, supported by Oracle IDE = development “environment” for middleware software default configuration for Oracle DB includes: syntax directed editors for JSP, Java page flow generator, GUI builder w JSF UML class builder + reverse engineer from tables, code forward generation of beans, tables (TopLink OR mapper) table editor and viewer local container server (OC4J) option to install copy of Java VM ( has separate tool for web services flow) … it is also very big, very slow, … issue of learning curve !

Fall CIS 764 Database Systems Engineering equivalent to: NetBeans JBuilder enterprise Eclipse enterprise config Visual Studio Enterprise version typically contains: provision for DB connection object –relational mapping tool UML tool local web server (for testing) deployment tool

Fall CIS 764 Database Systems Engineering First Jdev homework: Build a simple Swing application: it has some input, it has some control (a button) it uses the input in some way it has some output. Present a few, small screen snapshot: show some step in Jdev show some steps of execution of the app. post a link to the code. For example: Aghsan Hello AppAghsan Hello App Note: images about 40K each.
