The Basics Of XML Schema
XML schema definition languages are based on the recommendations of the World Wide Web Consortium (W3C). They use XML 1.0 syntax and aim to explicit describe the structure of XML documents and constrain the data which they may contain. They offer a distinct improvement on the more limited schema features offered by the Document Type Definition (DTD) recommendation which formed part of the original XML specification released in 1998. The most widely used schema language is the one defined by the W3C in 2001: W3C XML Schema. However, there are alternatives, such as RELAX NG and Schematron.
Schema documents are the successors to DTDs and overcome some key limitations associated with them. Firstly, DTDs do not support data types. Secondly, DTDs do not support namespaces. Thirdly, DTDs do not allow developers to accurately define the number of permitted occurrences of elements within their parent element.
XML schema documents describe the structure of an XML instance document by defining what each element must or may contain. An element is limited by its type. For example, an element of complex type can contain child elements and attributes, whereas a simple-type element can only contain text. The diagram below gives a first look at the types of XML Schema elements.
Schema documents have three main purposes. Firstly, they can be used to validate XML documents. Secondly, they can be used as a dictionary or grammar for the creation of a given class of XML document. And, thirdly, they can be used to provide documentation for XML documents.
An XML schema is itself an XML document and it contains definitions of all elements and attributes permitted in a class of XML documents. The schema also specifies the structure or hierarchy to which elements must adhere and the type of content each particular element may contain. Elements may be of the simple or complex type. Complex type elements may contain child elements as well as attributes. Simple type element may only contain data. XML documents using a particular schema are referred to as instances of the schema. An XML instance that correctly adheres to its associated schema is said to be valid.
Validation is usually the principal role of schema documents. Validation offers many benefits. It ensures the consistency of data within a document. It ensures that data has the right structure and internal hierarchy. It ensures that data within the document structure is of the correct type. It allows us to receive data from multiple sources.
Most XML documents are produced by programs and scripts written to extract information held in databases and transform it into XML. However, it is also possible for human beings to create XML documents. Schemas can be used during this process to assist in the document creation process. XML schemas also provide a mechanism for documenting XML documents and form an important part of the specification of XML vocabularies.

Audience handouts are a way of giving the attendees of your PowerPoint presentations something to remember you by. They normally consist of printouts of the presentation; one, two, three, four six or nine slides to a page. Naturally, however, whether or not the essence of your presentation can be captured by this kind of printout depends on the nature of the presentation.
To customise the appearance of handouts, click on the View tab of the PowerPoint ribbon and then click on the Handout Master button. In PowerPoint, masters allow you to determine the format of the three main elements within a presentation; slides, speaker notes and handouts. When you are in handout master mode, the Handout Master contextual tab appears. It contains a Page Setup section which allows you to choose the orientation of both the page as a whole and of the individual slide miniatures. It also contains buttons for activating or deactivating the header, footer, date and page number as well as for formatting the background of the slide.
Given that Microsoft PowerPoint allows you to produce three separate elements (slides, speaker notes and handouts), when the print command is used, you need to specify which of these elements you wish to print. This is done by choosing an option from the Print What drop-down menu. In addition to the three elements mentioned above, you can also print the outline of the presentation.
If you have created a presentation with a fair amount of important detail, it may be more useful to print out the slide outline and distribute it to the audience in place of PowerPoint’s usual handouts. Better still, you can export your presentation into Microsoft Word and then customise it for your audience. To export an outline, from the Office button, choose Publish and then Create Handouts in Microsoft Word.
When exporting to Word in this way, you will be presented with a dialogue box which allows you to choose one of five page layout options. Firstly, you can have speaker notes next to slides. This will create a two column layout with a slide miniature in column one and speaker notes next to it in column two. If you have used the speaker notes feature in your presentation, this may be a useful solution. The second option is Blank Lines Next to Slides: this produces the same two column layout as the first option but the right hand column is blank, so that you can enter notes next to each slide.
The options Speaker Notes Next to Slides and Blank Lines Next to Slide don’t offer you much room for text. If you have made or wish to make extensive notes on each slide, options three and four (Notes below Slides and Blank lines below Slides) provide a layout with the text below the slide miniature and leaves approximately 60 percent of the page free for notes.
If you simply wish your audience to have a summary of the content of the presentation, you can choose the final option: Outline Only. This simply exports the text on each slide into Microsoft Word.
When using any of the above Word export choices, you have the option of activating the Paste Link feature. This will create a link between the exported file and the original PowerPoint presentation, such that, if the presentation is modified, the exported Word file will also be updated.

Navigating In Microsoft Excel 2007
Each Excel document is called a workbook and each workbook can contain up to 255 worksheets. To navigate to a particular worksheet, click on one of the tabs displayed at the bottom of your screen.
To the left of the tabs will find four navigation buttons. These are useful where you have a workbook that either contains lots of worksheets or has worksheets with very long names. The very first one makes the name of the first worksheet visible; the very last one makes the name of the last worksheet visible. The left pointing arrow makes the name of the previous worksheet visible and of course the right pointing arrow makes the name of the next worksheet visible. These icons don’t actually activate a worksheet; they simply make its name tab visible. To activate a sheet, you still have to click on that particular tab.
Worksheets can also be activated via the keyboard. To activate the next sheet to the right, hold down Control and press Page Down. This moves you forward through your worksheets are naturally holding Control and pressing the Page Up button moves you back to the left.
Once you have navigated to a particular worksheet, you will need to go to a particular cell or a particular section of that worksheet. Firstly, you can use the scrollbars to make different parts of the worksheet visible. Secondly, you can move around the worksheet using the arrows on your keyboard: down, right, up and left.
Excel also has some useful keyboard shortcuts for moving to the edges of a given body of data. To get to the right-most cell of your current range, hold down the Control key and press the right arrow key and of course to get to the bottom cell, hold down Control and press the down arrow.
It’s also possible to do exactly the same thing using the mouse. Position the cursor on one of the edges of the selection rectangle (the bold highlight which is displayed around the currently active cell) and then simply double-click. Double-clicking on the right hand edge of the selection rectangle moves you to the extreme right of the current range. Double-clicking on the bottom edge moves the cursor to the bottom of the range, and so forth.
There are two final navigation key combinations which should be mentioned: Control-Home and Control-End. Hold down the Control key and press the End key to move to the bottom right of the current range. Hold down Control and press Home to move to the top left of the current range.
As well as navigating through worksheets, all users of Excel make frequent use of the Ribbon. Excel offers a series of useful keyboard shortcuts when working with the Ribbon.
To access Ribbon keyboard shortcuts simply press the Alt key once. A series of numbers and letters is then displayed. These represent the shortcuts that you should type to activate that part of the Ribbon. For example, “W” is the shortcut key for activating the View Tab.
When you press “W”, the View Tab is activated and another series of badges is displayed on each of the commands within the View Tab. For example, the “Arrange All” command uses “A” as its keyboard shortcut, so simply typing “A” is equivalent to clicking the Arrange All button.
Once you’ve typed a letter to execute a command, the Ribbon loses focus and the shortcut badges disappear. To access Ribbon commands via the keyboard once more, simply press the Alt Key and the badges will reappear. This means that you never have to worry about learning keyboard shortcuts. All you have to remember is to press the Alt key on your keyboard and Excel will prompt you from there.
