  1. MySQL Workbench. The Ultimate Guide to DBA Productivity: Writing Plugins and Scripts Vladimir Kolesnikov Software Engineer, Developer Tools

  2. Session Contents • Workbench General Overview • Workbench Architecture, GRT • [break] • GRT Shell • LUA scripting and Libraries • [break] • GRT LUA Plugins • [break] • GRT C++ Plugins

  3. Workbench General Overview • EER modeling tool • Overview page lists model entities • Canvas is where you visually create and edit your EER models • Use export/import/synchronization tools to interact with live servers or store data in SQL scripts • Use validation tools to check your models • Various utilities for your convenience – printing, export to PDF, PNG… • Cross-platform with native GUIs. Runs on Win 32/64 XP/Vista, with OS X and Linux coming soon

  4. Workbench General Overview • Two Editions – OSS and Standard

  5. Workbench Architecture • Workbench core manages the most essential functions • OS Abstraction • Inter-thread communication and messaging • Graphics • GUI • Generic APIs • GRT (Generic Run-Time) System • Object model, built after the architecture of dynamic languages (such as Objective-C) • Modules and scripting support

  6. Workbench Architecture • Modular Decomposition

  7. Workbench Architecture • Threading & Messaging Model

  8. Workbench Architecture • Modules and Scripting Support

  9. Workbench Architecture • GRT Object Model

  10. GRT Shell • Shell is command line interface to the Workbench internals • Uses LUA for Scripting • Supports single- and multi-line editing modes • Can be used for script debugging • Start using shell • Opening shell: Ctrl-F3 • Getting help: /> ? [subtopic-name] • To enter multi-line mode: Shift-Enter • To launch commands in multi-line mode: Ctrl-Enter

  11. GRT Lua Scripting and Libraries • Why LUA: • Fast • Light-weight • Portable • Easily-embeddable • LUA Standard Libraries Handle All Basic Functions • Runtime support • Strings, numbers, conversions, other utility • Data structure manipulation • Threading

  12. GRT Lua Modules & Plugins • Modules are loaded at Workbench startup and become globally visible • Use predefined source templates • Use Workbench scripting framework to create/edit/manage scripts • Use GRT Shell for debugging your code • You can re-use existing modules from your code

  13. GRT C++ Modules & Plugins • Use C++ for Implementing complex and/or computation-intensive modules • Use Workbench abstractions facilities for implementing platform-independent code • Implementing GUI • Windows: Use Windows Managed/Native Interop services for interfacing with GUI part • Linux: GUI is based GTKmm which is a C++ framework • Mac OS X: You can mix C++ and Objective-C code within the same source to implement COCOA-based GUI
