D4: Tutorial on MoWeS and phpMyAdmin - Homepages.stca.herts ...

<strong>D4</strong>: <strong>Tutorial</strong> on MoWeS and phpMyAdminIn this tutorial, you will be asked to learn how to:• Download, “install” and launch the MoWeSplatform• create, import and export a database into yourMoWeS based mySql database• use phpMyAdminYou should then start exploring the functionalfeatures of the VF1 PHP developmentframework.1

Downloading and launching MoWeS• Download the MoWeS from the following URL:http://homepages.stca.herts.ac.uk/~comqvv/wos_csitde.zip• Unzip the archive into your own UH drive (U://) or withinyour memory stick (D:, or E:, etc.)• You should obtain a folder called “wos_csitde”, whichincludes:• Launch the .exe filewos_csitde2

Access the MoWeS via your browser• The <strong>D4</strong> submission will be evaluated against Firefox.• If Firefox it is not installed on your lab machine, youshould download and install a portable version of thisbrowser (called Mozilla Firefox, Portable Edition) withinyour UH drive, or within your memory stick: you candownload it from:http://portableapps.com/apps/internet/firefox_portablefirefox_portable• For development purposes, you might want to considerinstalling on Firefox a special “add-on”, Web Developer:https://addons.mozilla.org/en-US/firefox/addon/webdeveloper/3

phpMyAdmin: Step 1Launch MoWeS, open Firefox and go to:http://localhost:8080/phpmyadminGet into your airplaneticket database (by clicking on themenu on the left of phpMyAdmin main page)You should find several tables:Airline, location, flight, etc.These tables are used by the case study application (anairplane ticket booking management system) developedby using the VF1 PHP development framework.You should use these tables and the application as a“knowledge repository” in order to develop your DMS-Papplication for the <strong>D4</strong> assignment.4

phpMyAdmin: Step 2Get back to phpMyAdmin main page (click on the smallhome icon on the top left side) and create a newdatabase: call it “cw0910”Now open a new tab on Firefox, and download the SQL filefor importing the a database fromhttp://homepages.stca.herts.ac.uk/~comqvv/csitde/d4/cw0910.sqlFirefox will display the SQL code.You should just save it by right-clicking and select the “SavePage As...” option, and save the cw0910.sql file into anew folder called cw0910, say atU:\wos_csitde\www\cw0910\6

phpMyAdmin: Step 3Now go back to your Firefox tab displaying yourphpMyAdmin, click on the Import link and...8

phpMyAdmin: Step 4Import the SQL text file you have saved 2 steps ago...Just click Go, after you Open the file9

phpMyAdmin: Step 5 (well done!)If everything has gone as expected, you should now have fourtables within your cw0910 database.These tables are tobe fully analysed andunderstood.Can you spot anyforeign key?Can you reconstructthe ERD behind thisdatabase?10

POST TUTORIAL: Step 6 (for your <strong>D4</strong>development exercise)• You can add new data on the four tables (not in the “venue”table, though)• Should anything go wrong, you could delete the four tablesand re-import them again, at your convenience, always bydownloading the file from:http://homepages.stca.herts.ac.uk/~comqvv/csitde/d4/cw0910.sql• Actually, you should start adding new data by usingphpMyAdmin now.11

POST TUTORIAL: Step 7First, consider the following data-model:Yes, this is the ERD behind the cw0910 database!Second, try to understand how it has been implemented.You need to consider what venues have been listed.Create a scheme, by means of which you start analysingthe data included in the four tables.12

POST TUTORIAL: Step 8Write some SQL queries to in order to answer the questionsbelow. Use the “SQL” tag in phpMyAdmin to execute yourqueries.1) Who is going toplay judo?2) Where are thejudo match to beheld?3) Are all judoathletes playingin the samedates?13

VF1Although VF1 has been included within your MoWeSplatform, you could always get the latest version of thespecimen application from:http://homepages.stca.herts.ac.uk/~comqvv/vf114

Familiarize with VF1Open the specimen application with Firefox, at:http://localhost:8080/vf1_application/• Add new ailrines,• edit existing flights,• search for existing locations• Explore how the many-to-many relationship has beenimplemented both on the database and within the GUI.• Try to get to the code!15
