This page introduces the overall features regardless of the Derby 3.0 editions. Please read the feature lists of your edition of interest to determine whether or not a characteristic is available. The lists of each editions are accessible from the Derby 3.0 Home Page.
Intuitive User InterfaceDerby delivers a clean, sleek user interface that puts the focus on the visited data instead of the browser. 90% of the main window is composed of a tree view of explored the data. You see a scroll bar only when you need one. The position and design of buttons have been specially selected to be effective in the minimum of space. 
ResponsivenessOpening and crawling resources may last a variable amount of time according to the nature of the accessed data. Derby makes use of various techniques to defer most of its activities, avoiding congestions, keeping your navigation responsive and letting you browse your data as seen as each resource is processed, even if more remains to be done. Smooth Mouse Wheel GestureDerby implements advanced mouse wheel control to improve your browsing experience. Scroll up and down from one to hundreds rows in a single rotation of your mouse wheel. Just put the desired acceleration and see the scroll pane sliding and bouncing when it reaches the tree extents. Keyboard and Mouse NavigationBrowse faster and more productively using keyboard and mouse shortcuts. Navigation HistoryAs most Web browsers, Derby keeps track of your navigation, allowing you jumping back and forth in your browsing history. Customizable ColumnsDisplay only the information you need and in the order you want by toggling on or off any column of the browser. Switch their positions as simply as a drag and drop. 
Occurrence LimiterAlthough a folder generally contains less than a thousand of files, Derby may access data exposing a very large number of data elements. Because a conventional tree representation is not suitable for displaying thousands of elements, Derby introduces an advanced graphical representation capable of both showing at any one time a reduced number of elements but allowing all of them to be viewed through a scroll-bar mechanism.

Image DisplayVisualize images from standard file formats to advanced scientific data with a simple double-click. Derby's image viewer implements advanced image processing and visualization features to display large images of more than a Gigabyte. Most image adapters include predefined operators that provide you with the best previews without user configuration e.g. automatic normalization to the current viewed region of interest, band selection, clipping, masking, etc. 
Multi-Formats and Multi-DomainsDerby relies on the advanced DRB technology to access data. This characteristic makes Derby as independent of the data types as DRB can handle them, and makes it "a priori" compatible with multiple formats and multiple domains. Hundreds of data types are already available and many are in the pipelines of running projects. Check out the features specific your target edition from Derby's Home Page to get the complete list of supported formats. Automatic Recognition of Data TypesDerby uses advanced Ontology topics to recognizes automatically the data types and associate its corresponding resources, such as class names, content descriptors, image descriptors, etc. The matching mechanism is far more advanced than usual MIME types that generally rely only on the filename extensions. Derby can match data types according to rules based on information extracted or computed from multiple resources such as the content of multiple files located in different directories or more. Browse Local and Remote DataDerby can access your local devices such as hard-disks, removable drives, CD-ROM’s, DVD’s, USB devices but also networked disks or remote resources accessed through transfer protocols e.g. FTP. XQuery/XPath ProcessingDerby is not only capable of accessing data located by an URL such as Web browsers do, but can display data resulting from an XQuery or an XPath. This advanced behavior let you use the location bar for selecting, filtering but also computing and constructing the data to be displayed! Resource CachingDuring one session, a dedicated caching system makes Derby learning the type of data you are visiting, makes it avoiding unnecessary reloading of associated resources and finally makes it faster during your navigation. This cache system also takes care of the maximum amount of memory allocated for the loaded resources and evicts the extras as needed. |
