Analytic functions compute an aggregate value based on a group of rows. They differ from aggregate functions in that they return multiple rows for each group. For more information about Oracle9i functions, refer to Oracle9i SQL Reference or Oracle9i Data Warehousing Guide.
A business area is a collection of related information in the database. The Discoverer manager works with the different departments in your organization to identify the information that each department requires from the database.
Conditions are worksheet items that enable you to select what data to display on worksheets. Conditions filter out data that you are not interested in, enabling you to concentrate on data that you want to analyze. For example, you might use a condition to display only data for the month January.
Items are different types of information stored in a folder. For example, if a Products folder contains reference numbers, descriptions, and the price of each product, the items in the Products folder are reference number, description, and price.
A List of values (LOV) is a list of valid values for an item. For example, a LOV for a year item might contain the values 1998, 1999, and 2000.
A page item is a filtering item located above a worksheet in the Page Items area. Page items enable you to look at one area of information at a time. For example, if an item called Month is placed in the Page Items area, you might select January from the page item drop down list to produce a January report, then select February to produce a February report and so on.
Parameters are workbook items that enable Discoverer users to enter dynamic input values used to analyze worksheets. Input values are typically used to:
A query is a question that Discoverer asks the database in order to get the data that you want to analyze.
Every time you open a worksheet or create a new worksheet, Discoverer sends a query to your company's database. For example, how did Product A sell last month?
Note: Queries are written in Structured Query Language (SQL), a language that databases understand. You do not need to understand SQL to communicate with the database - Discoverer writes the SQL query for you!
Workbooks are Discoverer files that contain worksheets displaying data retrieved from the database.
If you are familiar with spreadsheet applications (e.g. Microsoft Excel), think of a workbook as a spreadsheet file.
Worksheets contain the data that you want to analyze, together with a number of Discoverer components to help you analyze the data. For example, a worksheet can contain parameters, totals, percentages, exceptions, and calculations.
If you are familiar with spreadsheet applications (e.g. Microsoft Excel), think of a workbook as a spreadsheet file and worksheets as different sheets in that spreadsheet file.
