Notes de l'éditeur
- Some general purpose applications to be covered: Browsers, word processors, spreadsheets, database management systems, presentation graphics
- General-purpose applications include browsers, word processors, spreadsheets, database management systems, presentation graphics. These types will be the focus of this presentation. Special-purpose applications , also called advanced applications, are specific to one discipline or occupation. These include multimedia, Web authoring, virtual reality, and artificial intelligence (AI). (See chapter 10)
- The user interface is one of the most important part of a software application. If the user doesn’t like or is confused by the interface, then they won’t use it. Most common user interface today is a graphical user interface. (GUI) Pronounced “gooey”
- Windows are the portion of the screen where the user interacts with the application software.
- Menus are commands and options grouped together in common functionality. For example, the File menu displayed above lists commands and options associated with file maintenance.
- Toolbars allow quick access to commands in the application. Toolbars can usually be found under the menu bar. However, they can also be found detached and floating somewhere in the application window. That allows the user to customize their screen. The formatting toolbar above is seen in the vertical position as opposed to the horizontal like the standard toolbar. Most applications in the Windows environment will have toolbars like those seen above.
- Explain what students would find using the different tabs How is information listed on Contents Tab? How is information listed on Index Tab? How might a user use the Find Tab?
- Another way to get help is to: Access through F1 function key or Help button on toolbar or click on Office Assistant object (paperclip, ball, cat, dog, Einstein, robot…)
- ASP are web sites that offer access to different programs such as word processors, spreadsheets, etc. Users can also store their data on those servers. The advantages are that programs and data are easily accessible from any location that has access to the Web. A disadvantage is that the files are more vulnerable to hackers or others as compared to a local machine separate from the Internet. Balance must be found – security versus accessibility. An example of an ASP is www.WebOS.com Some ASPs require a fee, while others may only require registration. See the McGraw-Hill website at http://www.mhhe.com/oleary for further updates and to learn more.
- The browser interprets the HTML commands in the document to display the Web page. The first page of a web site is called the Home page. Navigating the web means following hyperlinks from document to document. See Chapter 8 for more detailed discussion of Internet and the Web
- Search services such as www.google.com, or AltaVista maintain huge databases that contain links to Web pages and Internet sites.
- Makes creation of professional looking documents easy. Most make use of templates to standardize the look of documents created by teams of employees.
- Word processors make it easy to professionally layout, edit, and distribute documents. Word wrap will automatically move text to new line when prior line is full. Incorrect spelling is identified and alternatives offered. Identifies poor grammar and makes suggestions. Quickly locate with search or find commands. Other features include AutoText and AutoComplete which anticipate phrases and words and will insert them upon request. Modern word processors allow addition of multimedia objects, such as charts, audio/video clips. See object linking and embedding (OLE)
- Also known as worksheets Consist of grid of numbered rows and columns. Common uses include analyzing sales trends, financial trends, home budgets, recording grades or scores To learn more about software development leaders such as Microsoft, see the website at http://www.mhhe.com/oleary
- The worksheet is a rectangular grid of rows and columns, the intersection of which is called a cell. Each cell is referenced by a letter (column) and number (rows). Data is stored in the cells. Workbooks are made up of several worksheets. Values are numbers used for calculations; Labels are letters, numbers, or symbols used to represent text (social security number, phone number) Formulas are calculations user creates that calculate results from referenced cells Functions are predefined formulas created by spreadsheet “What if “ scenarios - allows a user to create different scenarios for different results - probably one of the most powerful tools of spreadsheet
- Establishes a structure for data storage, usually relational using related tables, so related data can be easily retrieved; also known as DBMS (database managements systems) Can edit, retrieve, and display in different formats (reports or forms)
- Relational databases organize data into fields, records, tables Tables can be linked by a key field, one that is common to both the tables in question Access, Oracle are examples of relational databases. Hierarchical databases are not seen much today. Old databases include IBM’s DL/1, and Unisys DMS1100 Network, or also known as CODASYL, databases are structured in records connected by sets. Example is Micro Data Base Systems, Inc. TITANIUM. Object oriented databases are structured with data objects stored in classes. ODMG is a set of standards developed for object databases.
- Identify the key organization features of a standard database
- All DBMSs allow the user to access the data by locating, analyzing and displaying data in an organized manner Used for parts catalog, flight schedules, employee records, search engines, grocery store prices People use DBMS on daily basis – just not always aware Locate and display - ability to quickly locate records based on various criteria Sort and analyze - rearranging or computation based on various criteria Program Control languages - allow sophisticated users to access the database to perform complex queries, joins, deletes, or modifications.
- Picture of relationship table built in Microsoft Access Data from one table is related to the data in a second table by way of common key fields. A series of links let the users sort through, search, and display the data in a structured manner dependent on the search criteria.
- This presentation was created using PowerPoint Combines variety of visual objects to present attractive, professional presentations Many people learn better when information is visually presented Used in mostly in business and school environments See more on Lotus at http://mhhe.com/oleary
- Templates are files that include predefined settings that is used as a pattern to create a presentation. Used to maintain consistency between slides Animations add special visual and sound effects Delivery: Slide show – actual presentation to audience (similar to what we are doing now) Speaker notes – along with a picture of each slide, the audience receives a “notes” area to the right of each slide on which they can take notes as you give your presentation Link parts of your presentation to another application or another part of your presentation or even to the Web.
- A collection of separate applications bundled and sold as a group that share information between applications Less expensive than individual applications Microsoft Office Professional includes Word, Access, Excel, PowerPoint Other bundled suites: Corel WordPerfect Office, Lotus SmartSuite
- Can automatically update data from one application to another with proper link. An example is a chart in an Excel file is linked into a Word file. The data in the Word file will reflect any changes made to the Excel file.
- Added to a destination document where you can modify without altering original (source) document Files are not linked, so update in destination doesn’t affect source document Object in embedded app has look and feel of source application Can run the embedded file from the destination document
- Kind of a Jack-of-all-trades Ideal for less sophisticated users, like home or school, who don’t need the more sophisticated features found in the applications suites. Consult the O’Leary Expansion CD for more information on the Microsoft Works
- focus is on increased functionality, not a new command and menu structure More powerful functions increase the time for creativity, quality, and quantity New versions taking on look and feel of Internet (Windows XP and Office XP)
