CS317 File and Database Systems Using MySQL Workbench [PRClab] http://dev.mysql.com/downloads/workbench November 4, 2018 Sam Siewert Please Use Workbench 6.3.x You can install Workbench 6.3.x on your P: drive from O: drive (or T:\CS317) and run on an Campus wired machine The file ‘mysql-workbench6_Pdrive.zip’ can stay in the O:\ drive or it can move to the T:\ drive in a class folder you control. Your call. I included instructions inside the .zip file, screenshot: RS Sam Siewert 2 Please use Workbench 6.3.x You can download 6.3.x from Canvas and install on your own equipment and use Student VPN connection Sam Siewert 3 Resources for MySQL-Workbench Examine Use of MySQL Workbench to Go Between EER and Schemas Forward Engineer – From EER Entered into mysql-workbench to PRClab DBMS – Creates Tables, Keys, Views, etc. from Design Reverse Engineer – From DBMS to EER in myql-workbench – Useful to Understand and Improve existing DBMS Workbench Tutorial - Welcome to MySQL Workbench Sam Siewert 4 Methods to Connect to MySQL MySQL-Workbench must CONNECT to MySQL Server to use FORWARD/REVERSE Engineering Option 1 – Run mysql-workbench on PRClab1 with Display set back to your PC and use LOCAL connection – Basic-PRClab-Account-Verification-for-CS317.pdf – Or use MobaXterm for remote display and shell access to PRClab1 – Launch mysql-workbench on PRClab (/usr/bin/mysql-workbench) Option 2 – Run mysql-workbench on your PC on Campus EagleNet, with student VPN, or with SSH Tunnel to PRClab1 MySQL Server (complicated) Option 3 - Go to STEM Room 110 or Building 16 24 hour lab and start workbench from “Start” button - 8.0 CE Sam Siewert 5 Option-1 Setup Run mysql-workbench on PRClab with Display set back to your PC Enter prclab1.erau.edu on port 3306 (default port) connection for your account (ERAU username and password) Sam Siewert 6 Option-1 Example Start workbench On PRClab1 Displayed back to PC Enter your MySQL user and password Sam Siewert 7 Option-2 EagleNet or VPN Example There is no difference from Option-1 on EagleNet or VPN other than starting workbench locally on your PC! Start workbench On your PC Enter your MySQL user and password Sam Siewert 8 Option-2 SSH Tunnel Setup Generate SSH Keys on PRClab1 for your account – In directory .ssh Copy and paste id_rsa contents into file on your PC Truncated for security purposes – Start up mysql-workbench on your PC and set up SSH Tunnel using id_rsa private key on your PC Sam Siewert 9 SSH Tunnel Configuration SSH Tunnel PRClab1 prclab1.erau.edu Account PRClab1 prclab1.erau.edu id_rsa PRClab1 MySQL username Sam Siewert 10 Option-2 Example Enter PRClab Password Enter MySQL PRClab Server Password Now workbench is connected to PRClab MySQL Server over Tunnel Sam Siewert 11 Option-3 Example In STEM Room 110 or Building 16 24 hour lab, use Windows “Start” button to find workbench Configure a connection as before and run from PC Start workbench On Lab PC Enter your MySQL user and password Sam Siewert 12 Example Forward and Reverse Engineering USING MYSQL-WORBENCH Sam Siewert 13 A few Tips – for FORWARD Use both FORWARD and REVERSE Engineer For FORWARD, make MWB Design file Name Same as your DBMS Target – E.g. siewertsDHV1 – Make sure you have been Granted Privileges for this DBMS to DROP, and for all DDL Commands Rename if needed as shown Right Click Here – Change all Names and Save as Filename that MATCHES Sam Siewert 14 Going from Paper Design to Schemas Relational Models, ER, and EER on Paper are Helpful, but How Do We Transition to a Schema we Can Test? Workbench can be Downloaded and Installed on Windows, Max OS-X, Linux - http://dev.mysql.com/d ownloads/workbench Enter Design as an EER using Graphical Workbench Generate SQL DDL Schema When Ready… Sam Siewert 15 Reverse Engineer Existing Schema to EER DreamHome v. 1.0 – 6 Tables, Related by Foreign Keys Not Taking Advantage of EER, but Can Update Model and Export, Re- Import Data to Improve Sam Siewert 16 Sakila EER Model Tables, Views, SQL/PSM Routines, Triggers in ER Diagram Sam Siewert 17 Sakila Example Tables, Views, PSM Routines, Triggers Models Relations Between Entities [Tables] and Includes Operations [Routines] More Sophisticated Design and Schema that Matches Sam Siewert 18 Reverse Engineer Differences The Forward/Reverse Engineering is Not Perfect, but Not Bad SQL Generation from Pictures, Picture Generation from SQL Much like at GUI Code Generator Issue is Sync Between Design and SQL Sam Siewert 19 Recall DreamHome v. 2.0 ER Design Entities, Attributes, Keys, 1:1, 1:*, *:1 Relations – P. 359 Features PK and FK Attributes Sam Siewert 20 Improvements to DreamHome v. 1.0 Connections 1:n Made Via PKs Note InnoDB Physical Engine Required for FKs Improve Model and Schema FKs Require InnoDB, MyISAM default [Many options – MEMORY, FEDERATED, ScaleDB…] Sam Siewert 21 DreamHome v. 1.0 EER See if We Can Improve PK, FK and Normalization Sam Siewert 22 Check Schema and Add Test Data Review Schema Sam Siewert 23 DreamHome v. 2.0 Global EER Sam Siewert 24 Equivalent Using DH v. 1.0 Adapted Sam Siewert 25.
