2Introduction What is Discoverer Desktop Oracle Discoverer Desktop/Plus is a data access tool.You use it to view the information in your company’s databases.The whole purpose of Discoverer is to help you—the business professional—view the data you want from a database, analyze it to support your business decisions, and create reports to keep track of things.Discoverer Administrator is a tool to hide the complexity of the database from business users, so they can answer business questions quickly and accurately using Oracle Discoverer.3. Business intelligence is the ability to analyze data to answer business questions and predict future trends.
3How Discoverer Desktop Works We use it to view the information in your company’s databases.The whole purpose of Discoverer is to help you — the business professional—view the data you want from a database, analyze it to support your business decisions, and create reports to keep track of things.View data in a familiar format that is easy to read and understand.Prepare reports of your analytical results and findings. Share data with others, and in other applications (such as Excel).Discoverer Administrator is a tool to hide the complexity of the database from business users, so they can answer business questions quickly and accurately using Oracle Discoverer.3. Business intelligence is the ability to analyze data to answer business questions and predict future trends.
4The Discoverer Method of Data Access Your company’s Database Administrator identifies allthe data needed by separate business areas—accounting, human resources, sales, manufacturing, projects, finance, and so forth.The Database Administrator then organizesthe data for each business area.Workbooks in the business areas contain the specificdata needed for your various analysis tasks.
5Connectivity Connections can be made in two modes Normal Mode Apps ModeNormal Mode Connecting in Normal mode connects to the database directlyApps Mode Connects to the responsibilities and then connects to the database under lying that
6What You See on the Screen Workbook Window :The workbook window is where you will do most of your work withDiscoverer Desktop. It shows the data in the workbook.Four Types of Display (Layout)TablePage-Detail TableCrosstabPage-Detail Crosstab
7Layout Details Table Layout The most familiar layout for data, a table, lists data in rows and columns.Typical data for tables includes lists, such as a mailing list of customerssorted by zip code or customer name, lists of income or profit from variousdepartments, lists of products sorted by part number or part name, and so on.
8Layout Details --- Contd Table Layout with Page DetailsA table layout with page details is a table with multiple pages of data, whereeach page shows various portions of the data in detail.You set the criteria for displaying portions of data in order to see exactly whatyou want on each page.Usually you use this type of layout to study data details in a specific, recurringway. For example, in the Video Store data you may always want to seemonthly profits per region. In that case, each page would show one region’sprofits each month.
9Layout Details --Contd Crosstab LayoutA crosstab, short for “cross-tabulation,” relates two different sets of dataand summarizes their interrelationship in terms of a third set of data.Every crosstab has at least three dimensions of data—rows, columns,and data points.In Discoverer, crosstabs can show the interrelationships between manydimensions of data on the various axes.A crosstab layout has three axes: side axis, Because each axis can holdseveral data items, a crosstab can display many dimensions of data.
10Layout Details --Contd Page Detail Crosstab LayoutA page detail crosstab layout is a crosstab with multiple pages of data,so you can group the data on separate pages.You set the criteria for displaying portions of data in order to see exactlywhat you want on each page,
11Layout Details --- Contd Crosstab Layout with Page ItemsPage Axis.In this sample it contains a single data item--Department.(b) Top Axis.This top axis contains two data items--Year and Profit.(c ) Side Axis.This side axis also contains two data items--Region and City.
12Layout Details --- Contd Axis ItemsThe page axis, top axis, and left axis on the workbook window represent the data in your database that have a relatively few, discrete values associated with them.Axis items represent data that you can pivot on a crosstab worksheet or that can be column headings on a tableWhen creating a new worksheet, you identify the data that become axis items.Data PointsThe data points of a table or crosstab are the data in the "body" of the worksheet.Data points are the data that you want to use for analysis purposes or to see listed on a table.
13Workbook & WorksheetThink of a workbook as a binder file with specific data for specific tasks.The workbook has pages, or worksheets, that contain data for the specific tasks.For example, if the workbook is for sales and profit data,one worksheet in it might be a table listing your profit for sales versus rentals.Another worksheet might be a comparison of your profit over the last two years by sales region.To simulate with Excel, Excel file is Workbook and Sheets in the excel file are Worksheets
14Building Workbook/Worksheet The basic steps to create a new workbook or worksheet are as follows:NavigationFile > NewRequired StepsSelect the type of display for the new worksheet or workbook.Select the data that belongs on the worksheet or in the workbook.Optional StepsArrange the data on a table or crosstab layout.Sort the data (for tables only).Select conditions to apply to the data.Select calculations to apply to the data.
15Building Workbook/Worksheet -- Contd Open an existing WorkbookOpen an existing workbook will prompt you to open fromMy ComputerDatabaseScheduling ManagerRecently Used List
16Building Workbook/Worksheet -- Contd Selecting The DataThis dialog box lists the data in the business area that you can use to build the new worksheet.To include data on the new worksheet, you move it from the Available column to the Selected column.Select relevant columns from the table for sample report
17Building Workbook/Worksheet -- Contd AggregationsMathematical functions to aggregate the dataText Items- Such as Customer Name, the typical aggregations are Count, Max, and Min. That is, you can count the number of text items, or find the highest or lowest (where A might be the highest and Z the lowest).Numeric Data- The typical aggregations are Sum, Count, Max, Min, Average, and Detail.For example, you can find the Sum or Average of the numeric data with the aggregation.The aggregation in boldface type is the default.The database administrator sets which aggregation is the default.
18Building Workbook/Worksheet -- Contd Arranging LayoutsTo change the layout of items in your worksheet click and drag them to the desired location.
19Building Workbook/Worksheet -- Contd ConditionsPress button ‘New’ to add conditions.Our sample report does not have any conditions.Connect to EUL Displays the name of the EUL to which you are current connected.Create EUL Click Create EUL to create a new EUL for the current user or another user in the database. If you have sufficient database privileges, you can also create a new user and an EUL for that user at the same time by clicking Create EUL.Delete EUL Click Delete EUL to delete the current EUL. You can only delete the current EUL.Install Tutorial Click Install Tutorial to import the tutorial data into the current EUL. If the tutorial has never been installed before, you must have sufficient database privileges to install the tutorial data.Uninstall Tutorial Click Uninstall Tutorial to delete the tutorial data from the current EUL.
20Building Workbook/Worksheet -- Contd Data Sorting- Tabular LayoutSpecifies how data in the current table should be ordered.This step only applies to tables.Apply sorting type in the sample report for tabular layoutWho will own the EUL?Select an existing user Choose Select an existing user to create an EUL for a user that already exists in the current database. This new EUL replaces any existing EUL for that user. Select the user from the User drop down list.Create a new user Choose Create a new user to create a new user in the database and an EUL for that user. You must have sufficient database privileges to create a new user.Grant access to public Select this option to make this EUL accessible to all users in the current database. If you do not select this option, only the user who owns the EUL will be able to access data through this EUL.New EUL is for use by Oracle Applications users ONLY- Select this check box if you want the EUL to be restricted to Oracle Applications users.- Clear this check box if you want to create a standard EUL.Enter the EUL user’s passwordUser Select the existing user’s name (userid) from the drop down list, or enter a new user’s name. If this new EUL is for the current user, you do not have to enter a password.Password Enter the password for an existing user, or enter a new password for a new user. This field is unavailable if the new EUL is owned by the current user.Confirm password Enter the unique password you created for a new user. If you are creating this EUL for an existing user, you do not have to confirm the password. This field is unavailable if the new EUL is owned by the current user.

This is only available for result workbooks.EditClick Edit to change the schedule for a workbook. This is only available if you have selected a workbook that has been scheduled previously (not for result workbooks).View errorClick View error to display the error file generated when your workbook could not successfully query the database. (This is available for workbooks whose status says Error during Batch Report or Error in Submission.)DeleteRemoves the selected scheduled workbook from the Scheduling Manager. This means the workbook will no longer run automatically at a prespecified time. However, this does not delete the workbook itself. You can still open the workbook and view the data manually.ScheduleOpens the Schedule Wizard where you can schedule a workbook not listed in the Schedule Manager list.RefreshUpdates the information displayed in the Scheduled Workbooks list.
52Schedule WorkbookThe Schedule Wizard lets you schedule a workbook (or part of a workbook) to run at a later time.This is helpful if your query is going to take a long timeScheduling a workbook to run later allows you to keep working now and get your data later without even being at your computer.You can even have the same workbook run on a regular basis so you can update the data on a regular basis without doing any additional work.File> Manage Workbooks> SchedulingSelect the sheetsSelect the sheet(s) you want to run automatically. The sheets listed are for the current workbook. Click Select all to run every sheet in this workbook.Schedule this workbook onChoose the date and time you want this workbook to run automatically.How often do you want to repeat this schedule?You can run this workbook as often as you like.Never runs the workbook one time, at the time you specified above.Repeat every runs the workbook the number of times you specify in the time period you specify in the two drop-down boxes respectively.
53Sharing WorkbookFile> Manage Workbooks> SharingSharing a workbook grants other people access to it to view, analyze, and print the data.You can share workbooks with other people by setting up sharing two ways:Assign a group of people who can share one of your workbooks.Assign one or more workbooks that one other person can share with you.WorkbookLists the available workbooks.UsersShows Available users and Shared users.AddAdds a selected user to the Shared list.DeleteRemoves a selected user from the Shared list.
54Retrieving/Count All Rows Rows for tables are fetched from the database incrementally in groups.The number of rows in each group is specified in the Options dialog box based on the value set in the option “Retrieve data incrementally in groups of.”Click the Query Governor tab on the Options dialog box to see that option (Sheet> Edit Sheet> Options)To override that setting you can retrieve all the rows at once instead of incrementally (Sheet > Retrieve All Rows).****Retrieving all rows applies only to tabular style reports.To count the number of rows (Sheet > Count All Rows), A message will display the total number of rows.
55Refreshing the Worksheet Refreshing a worksheet re-queries the database and displays the worksheet’s data based on any new data.A primary use of refreshing a worksheet is when you’re using Discoverer in conjunction with real-time data.To refresh a worksheet (Sheet > Refresh Sheet)
56ParametersParameters are placeholders used instead of specific values in the definition of a condition.Parameters offer choices of condition value at the time the data loads.When you open the workbook, you will be prompted to enter a value and the results you receive will be specific to that value.
57Creating ParametersParameters dialog box enables you to define Parameters, which are placeholders used instead of specific values in the definition of a condition.You can create Parameters at two levels:1. Workbook level - Here, the Parameter applies to all worksheets in your workbook.2. Worksheet level - Here, the Parameter applies to the current worksheet only.Tools> ParametersAvailable ParametersLists available parameters.DescriptionDisplays a description of a selected parameter.NewDisplays the New Parameter dialog box.EditDisplays the Edit Parameter dialog box.DeleteDeletes a selected parameter.Move UpMoves a selected parameter up one level.Move DownMoves a selected parameter down one level.BitmapSet Bitmap displays the Open dialog boxDefault Bitmap uses the default bitmapClear Bitmap clears any specified bitmapOKApplies the parameter.
