Oracle Developer Suite

Forms & Reports


Oracle developer suite tools
Oracle Developer Suite Tools

Oracle Developer Suite contains the following main components:

  • Oracle Forms: For designing data entry forms.

  • Oracle Reports: For designing reports.

  • Oracle Jdeveloper: For developing Java applications or applets.

  • Oracle Warehouse Builder and Discoverer: OLAP tools for creating data warehouses and OLAP user interfaces.

  • Oracle Designer: Oracle's CASE tools that include modeling and code generation capabilities.


Forms reports
Forms & Reports

This tutorial covers the Developer Forms and Reports components.

We develop applications (forms, reports, menus, etc.) to make the job of data manipulation easier for users.




Form developer
Form Developer

  • In Oracle Forms, a form (or data entry form) acts like a window into the database schema.

  • An individual focuses the attention of the user to one or a few of the tables at a time.

  • Form can give prompts so the user knows what kind of input is expected and how data is to be entered and manipulated.

  • Every form in Oracle Forms has the capability to:

    • Query existing data in a table,

    • Modify existing data in a table,

    • Add new data (records) to the table.


Form developer1
Form Developer

  • A form is built up using one or more data blocksthat correspond to tables in the database.

  • Fields within the data block correspond to columns in the database table.















Prerequisites
Prerequisites

  • You must have a valid user account

    • in an Oracle server,

    • or a local installation of an Oracle database.

  • Existence of tables in the user's schema.


Important notes saving
IMPORTANT NOTES - SAVING

  • Forms & Reports can be saved in files in a directory of your choice.

  • Save them in a folder(subdirectory) on the local hard disk, on a flash memory or on a floppy disk.

  • You will have difficulty running any form saved in a folder that has spaces or punctuation other than the underscore character in the name.

    • For example, they will not run if you save them on "My Documents“ or on the “Desktop”.

    • It is critical that you DO NOT save the file with spaces in the file name.


Important notes compiling
IMPORTANT NOTES - COMPILING

  • Before executing (run) your form/Report, it must be Compiled and Built.

  • If there is an error (e.g., in the PL/SQL code, or if the database schema changes) it will be displayed in a window as its encountered.

  • Alternatively, Oracle Forms & Reports defaults to automatically compiling the form each time it is executed (run).


Important notes r unning
IMPORTANT NOTES - Running

  • Before running a Form or Report, the OC4J service should be started.

  • When run the Form or Report, the default web browser will be launched.

  • Oracle's JInitiator will load and the Form or the Report should appear.

  • To exit from a running Form or Report, pull down the Action menu and select the Exit menu item. Warning: Do not simply close the web browser as this will leave a Java Applet process running and this will lock your Form or Report.













The master detail relationship
The Master-Detail Relationship

  • The Master-Detail relationship is a relationship between entities shown as "One to Many" relationships.

  • A Department with many Employees is an example of this relationship.


The master detail relationship1
The Master-Detail Relationship

  • Oracle Forms implements the master-detail relationship using two data blocks.

  • The first block corresponds to the master table and the second block corresponds to the detail table.

  • There major function in a Master-Detail form is to guarantee that the detail block will display only records that are associated with the current record in the master block.


Report developer
Report Developer

  • Oracle Reports Builder allows the developer to create sophisticated reports in a variety of layouts and contains many customization features.

  • A report consists of objects that collectively define the report:

    • data model objects (queries, groups, columns, links, user parameters)

    • layout objects (repeating frames, frames, fields)

    • parameter form objects (parameters, fields)

    • PL/SQL objects (program units, triggers)

    • references to external PL/SQL libraries, if any
