Electronic commerce, commonly known as e-commerce, eCommerce or e-comm, refers to the buying and selling of products or services over electronic systems such as the Internet and othercomputer networks. However, the term may refer to more than just buying and selling products online. It also includes the entire online process of developing, marketing, selling, delivering, servicing and paying for products and services. The amount of trade conducted electronically has grown extraordinarily with widespread Internet usage.
Web development is a broad term for the work involved in developing a web site for the Internet (World Wide Web) or an intranet (a private network).
Uploading is the transmission of a file from one computer system to another, usually larger computer system. From a network user's point-of-view, to upload a file is to send it to another computer that is set up to receive it. People who share images with others on bulletin board services ( BBS ) upload files to the BBS.
Transmission in the other direction is downloading -- from one, usually larger computer to another, usually smaller computer. From an Internet user's point-of-view, downloading is receiving a file from another computer.http://whatis.techtarget.com/definition/0,,sid9_gci213255,00.html
Dreamweaver workspace elements
The Start page enables you to open a recent document or create a new document. From the Start page you can also learn more about Dreamweaver by taking a product tour or a tutorial.
The Insert bar contains buttons for inserting various types of "objects," such as images, tables, and layers, into a document. Each object is a piece of HTML code that enables you to set various attributes as you insert it. For example, you can insert a table by clicking the Table button in the Insert bar. If you prefer, you can insert objects using the Insert menu instead of the Insert bar.
The Document toolbar contains buttons that provide options for different views of the Document window (such as Design view and Code view), various viewing options, and some common operations such as previewing in a browser.
The Standard toolbar (not displayed in the default workspace layout) contains buttons for common operations from the File and Edit menus: New, Open, Save, Save All, Cut, Copy, Paste, Undo, and Redo. To display the Standard toolbar, select View > Toolbars > Standard.
The Coding toolbar (displayed in Code view only) contains buttons that let you perform many standard coding operations.
The Style Rendering toolbar (hidden by default) contains buttons that let you see how your design would look in different media types if you used media-dependent style sheets. It also contains a button that lets you enable or disable CSS styles.
The Document window displays the current document as you create and edit it.
The Property inspector lets you view and change a variety of properties for the selected object or text. Each kind of object has different properties. The Property inspector is not expanded by default in the Coder workspace layout.
The tag selector in the status bar at the bottom of the Document window shows the hierarchy of tags surrounding the current selection. Click any tag in the hierarchy to select that tag and all its contents.
Panel groups are sets of related panels grouped together under one heading. To expand a panel group, click the expander arrow at the left of the group’s name; to undock a panel group, drag the gripper at the left edge of the group’s title bar.
The Files panel enables you to manage your files and folders, whether they are part of a Dreamweaver site or on a remote server. The Files panel also enables you to access all the files on your local disk, much like Windows Explorer (Windows) or the Finder (Macintosh).

The Document toolbar
The Document toolbar contains buttons that let you toggle between different views of your document quickly: Code, Design, and a split view that shows both Code and Design view.
The toolbar also contains some common commands and options related to viewing the document and transferring it between the local and remote sites.

The following options appear in the Document toolbar:
Show Code View displays only the Code view in the Document window.
Show Code and Design Views displays Code view in part of the Document window and Design view in another part. When you select this combined view, the option Design View on Top becomes available in the View Options menu. Use this option to specify which view appears at the top of your Document window.
Show Design View displays only the Design view in the Document window.
Server Debug displays a report to help you debug the current ColdFusion page. The report includes errors, if any, in your page.
Document Title allows you to enter a title for your document, to be displayed in the browser’s title bar. If your document already has a title, it appears in this field.
No Browser/Check Errors enables you to check cross-browser compatibility.
Validate Markup lets you validate the current document or a selected tag.
File Management displays the File Management pop-up menu.
Preview/Debug in Browser allows you to preview or debug your document in a browser. Select a browser from the pop-up menu.
Refresh Design View refreshes the document’s Design view after you make changes in Code view. Changes you make in Code view don’t automatically appear in Design view until you perform certain actions, such as saving the file or clicking this button.
View Options allows you to set options for Code view and Design view, including which view should appear above the other. Options in the menu are for the current view: Design view, Code view, or both. For information about Code view options, see Setting coding preferences. For information about Design view options, see Selecting elements in the Document window, Viewing and editing head content, and Using visual guides in Dreamweaver.
Visual Aids lets you use different visual aids to design your pages.
The Insert bar

The Insert bar contains buttons for creating and inserting objects such as tables, layers, and images. When you roll the pointer over a button, a tooltip appears with the name of the button.
The buttons are organized into several categories, which you can switch on the left side of the Insert bar. Additional categories appear when the current document contains server code, such as ASP or CFML documents. When you start Dreamweaver, the category you were last working in opens. NOTE | | If you prefer to view the categories as tabs across the top of the Insert bar, you can change the layout of the Insert bar (see Setting Fonts preferences for Dreamweaver display). |
Some categories have buttons with pop-up menus. When you select an option from a pop-up menu, it becomes the default action for the button. For example, if you select Image Placeholder from the Image button’s pop-up menu, the next time you click the Image button, Dreamweaver inserts an image placeholder. Anytime you select a new option from the pop-up menu, the default action for the button changes.
The Insert bar is organized in the following categories:
The Common category enables you to create and insert the most commonly used objects, such as images and tables.
The Layout category enables you to insert tables, div tags, layers, and frames. You can also you choose among three views of tables: Standard (default), Expanded Tables, and Layout. When Layout mode is selected, you can use the Dreamweaver layout tools: Draw Layout Cell and Draw Layout Table.
The Forms category contains buttons for creating forms and inserting form elements.
The Text category enables you to insert a variety of text- and list-formatting tags, such as b, em, p, h1, and ul.
The HTML category enables you to insert HTML tags for horizontal rules, head content, tables, frames, and scripts.
Server-code categories are available only for pages that use a particular server language, including ASP, ASP.NET, CFML Basic, CFML Flow, CFML Advanced, JSP, and PHP. Each of these categories provides server-code objects that you can insert in Code view.
The Application category enables you to insert dynamic elements such as recordsets, repeated regions, and record insertion and update forms.
The Flash elements category enables you to insert Macromedia Flash elements.
The Favorites category enables you to group and organize the Insert bar buttons you use the most in one common place.

The tag selector shows the hierarchy of tags surrounding the current selection. Click any tag in the hierarchy to select that tag and all its contents. Click <body> to select the entire body of the document. To set the classor id attributes for a tag in the tag selector, right-click (Windows) or Control-click (Macintosh) the tag and select a class or ID from the context menu. The tag selector is the preferable method for selecting tags because it ensures that you are always selecting the tag with accuracy.
The Hand tool lets you click the document and drag it in the Document window. Click the Select tool to disable the Hand tool.
The Zoom tool and Set Magnification pop-up menu let you set a magnification level for your document. For more information, see Zooming in and out in Using Dreamweaver.
The Window Size pop-up menu (visible in Design view only) lets you resize the Document window to predetermined or custom dimensions. For more information, see Resizing the Document window in Using Dreamweaver.
To the right of the Window Size pop-up menu are the estimated document size and estimated download time for the page, including all dependent files such as images and other media files. For more information, see Setting download time and size preferences in Using Dreamweaver.
For more information about using the status bar, see Exploring the Workspace in Using Dreamweaver.
