XML in 10 Points:
Structured data includes things like spreadsheets, address books, configuration parameters, financial transactions, and technical drawings. XML is a set of rules (you may also think of them as guidelines or conventions) for designing text formats that let you structure your data. XML is not a programming language, and you don't have to be a programmer to use it or learn it. XML makes it easy for a computer to generate data, read data, and ensure that the data structure is unambiguous. XML avoids common pitfalls in language design: it is extensible, platform-independent, and it supports internationalization and localization. XML is fully Unicode-compliant.
2. XML looks a bit like HTML
Like HTML, XML makes use of tags (words bracketed by '<' and '>') and attributes (of the form name="value"). While HTML specifies what each tag and attribute means, and often how the text between them will look in a browser, XML uses the tags only to delimit pieces of data, and leaves the interpretation of the data completely to the application that reads it. In other words, if you see "
" in an XML file, do not assume it is a paragraph. Depending on the context, it may be a price, a parameter, a person, a p... (and who says it has to be a word with a "p"?).
3. XML is text, but isn't meant to be read
Programs that produce spreadsheets, address books, and other structured data often store that data on disk, using either a binary or text format. One advantage of a text format is that it allows people, if necessary, to look at the data without the program that produced it; in a pinch, you can read a text format with your favorite text editor. Text formats also allow developers to more easily debug applications. Like HTML, XML files are text files that people shouldn't have to read, but may when the need arises. Compared to HTML, the rules for XML files allow fewer variations. A forgotten tag, or an attribute without quotes makes an XML file unusable, while in HTML such practice is often explicitly allowed. The official XML specification forbids applications from trying to second-guess the creator of a broken XML file; if the file is broken, an application has to stop right there and report an error.
4. XML is verbose by design
Since XML is a text format and it uses tags to delimit the data, XML files are nearly always larger than comparable binary formats. That was a conscious decision by the designers of XML. The advantages of a text format are evident (see point 3), and the disadvantages can usually be compensated at a different level. Disk space is less expensive than it used to be, and compression programs like zip and gzip can compress files very well and very fast. In addition, communication protocols such as modem protocols and HTTP/1.1, the core protocol of the Web, can compress data on the fly, saving bandwidth as effectively as a binary format.
5. XML is a family of technologies
XML 1.0 is the specification that defines what "tags" and "attributes" are. Beyond XML 1.0, "the XML family" is a growing set of modules that offer useful services to accomplish important and frequently demanded tasks. XLink describes a standard way to add hyperlinks to an XML file. XPointer is syntax in development for pointing to parts of an XML document. An XPointer is a bit like a URL, but instead of pointing to documents on the Web, it points to pieces of data inside an XML file. CSS, the style sheet language, is applicable to XML as it is to HTML. XSL is the advanced language for expressing style sheets. It is based on XSLT, a transformation language used for rearranging, adding and deleting tags and attributes. The DOM is a standard set of function calls for manipulating XML (and HTML) files from a programming language. XML Schemas 1 and 2 help developers to precisely define the structures of their own XML-based formats. There are several more modules and tools available or under development.
6. XML is new, but not that new
Development of XML started in 1996 and it has been a W3C Recommendation since February 1998, which may make you suspect that this is rather immature technology. In fact, the technology isn't very new. Before XML there was SGML, developed in the early '80s, an ISO standard since 1986, and widely used for large documentation projects. The development of HTML started in 1990. The designers of XML simply took the best parts of SGML, guided by the experience with HTML, and produced something that is no less powerful than SGML, and vastly more regular and simple to use. Some evolutions, however, are hard to distinguish from revolutions... And it must be said that while SGML is mostly used for technical documentation and much less for other kinds of data, with XML it is exactly the opposite.
7. XML leads HTML to XHTML
There is an important XML application that is a document format: W3C's XHTML, the successor to HTML. XHTML has many of the same elements as HTML. The syntax has been changed slightly to conform to the rules of XML. A format that is "XML-based" inherits the syntax from XML and restricts it in certain ways (e.g, XHTML allows "
", but not " " stands for "paragraph", and not for "price", "person", or anything else). " mean "paragraph" from this format or "person" from that one?). To eliminate name confusion when combining formats, XML provides a namespace mechanism. XSL and RDF are good examples of XML-based formats that use namespaces. XML Schema is designed to mirror this support for modularity at the level of defining XML document structures, by making it easy to combine two schemas to produce a third which covers a merged document structure.
8. XML is modular
XML allows you to define a new document format by combining and reusing other formats. Since two formats developed independently may have elements or attributes with the same name, care must be taken when combining those formats (does "
9. XML is the basis for RDF and the Semantic Web
W3C's Resource Description Framework (RDF) is an XML text format that supports resource description and metadata applications, such as music playlists, photo collections, and bibliographies. For example, RDF might let you identify people in a Web photo album using information from a personal contact list; then your mail client could automatically start a message to those people stating that their photos are on the Web. Just as HTML integrated documents, images, menu systems, and forms applications to launch the original Web, RDF provides tools to integrate even more, to make the Web a little bit more into a Semantic Web. Just like people need to have agreement on the meanings of the words they employ in their communication, computers need mechanisms for agreeing on the meanings of terms in order to communicate effectively. Formal descriptions of terms in a certain area (shopping or manufacturing, for example) are called ontologies and are a necessary part of the Semantic Web. RDF, ontologies, and the representation of meaning so that computers can help people do work are all topics of the Semantic Web Activity.
10. XML is license-free, platform-independent and well-supported
By choosing XML as the basis for a project, you gain access to a large and growing community of tools (one of which may already do what you need!) and engineers experienced in the technology. Opting for XML is a bit like choosing SQL for databases: you still have to build your own database and your own programs and procedures that manipulate it, but there are many tools available and many people who can help you. And since XML is license-free, you can build your own software around it without paying anybody anything. The large and growing support means that you are also not tied to a single vendor. XML isn't always the best solution, but it is always worth considering.

Reply, then Reply All:
If you choose Reply, but then decide you want to include "all", you don't have to copy the reply you've created to the clipboard, close the email, and start over again this time pressing "Reply to All".
Instead, even if you first choose just "Reply" you can then click "Reply to All", and Notes will fill in the additional names for you.

Bill and Hold Basis:
The bill-and-hold basis is one method of revenue recognition. According to the Securities and Exchange Commission, it is the buyer's responsibility to request that a transaction be on a bill-and-hold basis and must have substantial business purposes in doing so. In addition to those criteria, any goods sold under this basis must be finished goods at the time of sale and not be available to fulfill any other orders.

Main components of Effective Presentation:
• Content
• Design
• Delivery
Each of these components has to be on the mark and they all have to work together, as well.
When writing your content, decide on two or three main points and make sure that everything else that you write leads to those points. Make your content logical, simple, and clear. Figure out what your audience needs and wants to know and tailor your content for the audience.
Regarding design, your number one concern is legibility. Don’t put too much text on a slide and keep it large enough to read easily. The text color should contrast highly with the background color. Then, make sure that your design complements your content. Your background and images shouldn’t detract from the content. Images should work to clarify text. The layout and size of text should bring important points to the fore.
Don’t forget a winning delivery. Engaging your audience with eye contact and your overall energy is important. Know your main points and emphasize them with your voice and the amount of time you spend on them. Two’s a party; three’s a crowd, they say. If you just read your slides, you’re putting PowerPoint between you and the audience and they’ll resent it. Instead, use the slides only as support for your presentation.

Rabbit Chase:
Bag Stuffer:
They're those little colorful slips of paper that have offers or coupons for savings that you often find in your bags after a day of shopping. These are a great way to promote your business and develop repeat customers.
They are very inexpensive to make and can be easily changed if a new promotion arises.
Queuing Theory:
Here are details of four queuing disciplines:
First in first out
This principle states that customers are served one at a time and that the customer that has been waiting the longest is served first
Last in first out
This principle also serves customers one at a time; however the customer with the shortest waiting time will be served first.
Processor sharing
Customers are served equally. Network capacity is shared between customers and they all effectively experience the same delay.
Priority
Customers with high priority are served first

Pull-Push Strategy:
In a "push" system the consumer does not request the product to be developed; it is "pushed" to the end-user by promotion. An example of this is a perfume product. Women do not request to smell a fragrance they never smelled before; it is simply "pushed" to them, through the right advertisement.
• Applied to that portion of the supply chain where demand uncertainty is relatively small
• Production & distribution decisions are based on long term forecasts
• Based on past orders received from retailer’s warehouse (may lead to Bullwhip effect)
• Inability to meet changing demand patterns
• Large and variable production batches
• Unacceptable service levels
• Excessive inventories due to the need for large safety stocks
In a "pull" system the consumer requests the product and "pulls" it through the delivery channel. An example of this is the car manufacturing company Ford Australia. Ford Australia only produces cars when they have been ordered by the customers.
• Applied to that portion of the supply chain where demand uncertainty is high
• Production and distribution are demand driven
• No inventory, response to specific orders
• Point of sale (POS) data comes in handy when shared with supply chain partners
• Decrease in lead time
• Difficult to implement

Find or Replace in all sheets of the workbook:
2. Press Ctrl+F to find or Ctrl+H to find and replace. (Note: Ctrl+F works only for a single sheet in Excel 97). In Excel 2002 and 2003, choose Sheet or Workbook from the within dropdown list (see the screenshot below).
Using wild cards in the text search:
Use * as a wild card for any number of characters, either before or after text, for example, searching for *CO will find both Cisco and Telco.
Use ? as a wild card for a single character, for example, searching for R?N will find Ron and Ran but not Rain.
To search for an asterisk, enter ~* in the search box.
Back Order:
Backorder Cost: A cost incurred by a business when it is unable to fill an order and must complete it later. A backorder cost can be discrete, as in the cost to replace a specific piece of inventory, or intangible, such as the effects of poor customer service. Backorder costs are usually computed and displayed on a per-unit basis.
Backorder costs include: costs of expediting, loss of customer goodwill and loss of sales revenues.
Backorder Date: Many vendors and retail businesses run into the problem of having backordered items, when they are waiting for the Manufacturer of a certain product(s) to deliver the expected goods. The manufacturer will give the vendor an expected date as to when the backordered item should be received. This date then becomes the backorder date for that specific item(s).
