What is data

TextBox looks like the following when there is a validation error: For an example of how to provide logic to validate all controls in a dialog box, see the Custom Dialog Boxes section in the Dialog Boxes Overview.Alternatively, they could contact the retailers directly about any data products that are available.The type of the StartDate property is DateTime, which returns a date that includes the time to the millisecond.

Connecting to the Facebook and Twitter APIs, or using another appropriate tool, will give access to data from these sources and allow the analyst to understand how articles are shared further.

Twitter and Facebook have well developed APIs for data or insights.

Data modeling is the analysis of data objects and their relationships to other data objects.In the case of Twitter, there are tools that allow deeper analysis beyond the API provided by Twitter.For an example, see Get the Default View of a Data Collection.

To get the maximum benefit from the framework you should be brutally honest with yourself and ask questions such as: Is data from a source really as Light and Close as it could be.In this particular example, the Source of the view is bound to the AuctionItems collection (of type ObservableCollection ) of the current application object.

Like any great general going into battle, to do this, you need to use a map.The next step is to prioritise a list of actions that will move data closer and lighten it for your business.Otherwise, the current item pointer is set to the first item of the filtered collection view.Also, for your business the exact definition of Dark or Light might be different from others.This puts Facebook and Twitter on the light side but distant from the company and Pinterest on the dark side of the line.NJIT School of Management professor Stephan P Kudyba describes what data mining is and how it is being used in the business world.Data sources that provide a well defined data product often come with the best documentation and the easiest education actions.However, to set up dynamic bindings so that insertions or deletions in the collection update the UI automatically, the collection must implement the INotifyCollectionChanged interface.What Triggers Source Updates Bindings that are TwoWay or OneWayToSource listen for changes in the target property and propagate them back to the source.

If the value is Highlight, the item has an orange border and a star.With the use of views, you can display that same data in different ways.Most UIElement properties are dependency properties and most dependency properties, except read-only ones, support data binding by default. (Only DependencyObject types can define dependency properties and all UIElement s derive from DependencyObject.) Although not specified in the figure, it should be noted that the binding source object is not restricted to being a custom CLR object.It is difficult to notice from the image but the items are also sorted by the start date within each category.The Data Conversion section provides information about converters.

The breadth and richness of data sources available is ever increasing, Data Landscaping is designed to help stopping this becoming overwhelming.You can do this using a SWOT, or set of box and line diagrams if you wish.Without specific instructions of how to display the data collection, the ListBox is displaying a string representation of each object in the underlying collection and the ContentControl is displaying a string representation of the object it is bound to.There is no real trick to getting started: draw the axis on a piece of paper or whiteboard and lay out what you know.

This site contains information on data warehousing and business intelligence, including processes in building data warehousing systems, business intelligence tools.For the previous example, instead of using the DataContext property, you can specify the binding source by setting the Source property directly on the binding declaration of the button, as in the following example.If you bind directly to a collection, WPF binds to its default view.
