    SQL Workbench/J is a free, DBMS-independent, cross-platform SQL query tool. It is written in Java and thus it should run on any operating system that provides a Java Runtime Environment. It's main focus is on running SQL scripts (either interactively or as a batch) and export/import features. Graphical query building or more advanced DBA tasks are not the focus and are not planned Current stable version: Build 110 (2011-02-13) Current development build: 110.5 ( 2011-04-25)

java opensource API framework logging slf4j log4j programming

    The Simple Logging Facade for Java or (SLF4J) serves as a simple facade or abstraction for various logging frameworks, e.g. java.util.logging, log4j and logback, allowing the end user to plug in the desired logging framework at deployment time. Before you start using SLF4J, we highly recommend that you read the two-page SLF4J user manual. In case you wish to migrate your Java source files to SLF4J, consider our migrator tool which can migrate your project into SLF4J in minutes. In case an externally-maintained component you depend on uses a logging API other than SLF4J, such as commons logging, log4j or j.u.l, have a look at SLF4J's binary-support for legacy APIs.

    Some of the common questions relating to cyclomatic complexity are "How does my code compare to others?" and "What is a good number for a particular class?" The iPlasma project answers these questions (see Resources). iPlasma is a platform, created as a university project in Romania, for quality assessment of object-oriented design. It generates a pyramid, showing key metrics for your project along with comparisons to industry-standard ranges for those numbers.

      The View Implementation

  • presenter.onAddButtonClicked();
  • ...91 more annotations...
  • onAddButtonClicked
  • eventBus.fireEvent(new AddContactEvent());
  • presenter needs to know more about the view
  • view needs to know more about the data model
  • data types are typically homogeneous within column borders
  • ColumnDefinition abstract class
  • houses the any type-specific code (this is the third party mentioned above)
  • ColumnDefinition
  • ColumnDefinition(s) would be created outside of the presenter
  • we can reuse its logic regardless of what view we've attached ourself to
  • update our views such that we can set their ColumnDefinition(s).
  • setColumnDefinitions
  • this.columnDefinitions = columnDefinitions;
  • so that we can pass in
  • a mocked ContactsView instance when testing our ContactsPresenter
  • in our AppController, when we create the ContactsView,
  • new ContactsViewColumnDefinitions().getColumnDefinitions();
  • we can initialize it with the necessary ColumnDefinition(s).

      Initialize ContactsView with the necessary ColumnDefinition(s)
  • With our ColumnDefinition(s) we can pass the model untouched.
  • As mentioned above we were previously dumbing down the model into a list of Strings
  • current solution
  • List<String> data
  • display.setData(data);
  • how that data type is rendered.
  • use generics
  • third party that abstracts
  • knowledge of a cell's data type
  • stringing together a list of these classes
  • providing the necessary render()
  • and isClickable()/isSelectable() override
  • ContactsViewColumnDefinitions<ContactDetails>
  • columnDefinitions =      new ArrayList<ColumnDefinition<ContactDetails>>()
  • ColumnDefinition<T>
  • ContactsPresenter
  • ContactsViewImpl
  • ColumnDefinition<T> columnDefinition = columnDefinitions.get(j);
  • the presenter can pass the model untouched
  • the view has no rendering code
  • that we would otherwise need to test. And the fun doesn't stop there.
  • presenter.onItemClicked(
  • presenter.onItemSelected
  • ClickEvent
  • cell.getCellIndex()
  • columnDefinition.isClickable()
  • SelectEvent
  • columnDefinition.isSelectable()
  • return shouldFireClickEvent;
  • return shouldFireSelectEvent;
  • respond to user interaction in different ways based upon the cell type that was clicked
  • use them for rendering purposes
  • defining how to interpret user interactions
  • we're going to remove any application state from the ContactsView
  • replace the view's getSelectedRows() with a SelectionModel
  • The SelectionModel is nothing more than a wrapper around a list of model objects.
  • ContactsPresenter holds on to an instance of this class
  • onItemSelected
  • Having the ColumnDefinition create a new widget for each cell is too heavy
  • Replace our FlexTable implementation with an HTML widget
  • calling setHTML()
  • Reduce the event overhead by sinking events on the HTML widget
  • rather than the individual cells
  • update our ContactsView.ui.xml file to use a
  • HTML widget rather than a FlexTable widget.
  • <g:HTML ui:field="contactsTable">
  • Inefficiencies related to inserting new elements via DOM manipulation Overhead associated with sinking events per Widget
  • for each item ask our column definitions to render accordingly
  • each column definition
  • render itself into the StringBuilder
  • rather than passing back a full-on widget
  • calling setHTML on a HTML widget
  • rather than calling setWidget on a FlexTable.
  • This will decrease your load time, especially as your tables start to grow.
  • we're reducing the overhead of sinking events on per-cell widgets
  • instead sinking on a single container
  • ClickEvents are still wired up via our UiHandler annotations
  • get the Element that was clicked on
  • and walk the DOM until we find a parent TableCellElement
  • we can determine the row
  • shouldFirdClickEvent() and shouldFireSelectEvent()
  • to take as a parameter a TableCellElement rather than a HTMLTable.Cell.
  • faster startup times via Code Splitting.
  • runAsync() points
  • split portion of your code is purely segmented
  • not referenced by other parts of the app
  • it will be downloaded and executed at the point that it needs to run
  • Do we really want to download all of that code before the user even logs in?
  • Not really.
  • simply grab the login code, and leave the rest for when we actually need it
  • wrap the code that creates the ContactsView and ContactsPresenter in a runAsync() call
  • as optimizations such as this one become easier and easier to implement.

    Jisql is a Java based utility to provide a command line interactive session with a SQL server. This application is conceptually modeled on the Sybase 'isql' program with, obviously, strong similarities to Microsoft SQL/Server isql and osql (as Microsoft got SQL Server from Sybase). The program can act in a similar way to Oracle's sqlplus and PostgreSQL's psql.
