This chapter provides an introduction to the Oracle Business Process Composer application.
This chapter includes the following sections:
Oracle Business Process Composer is a web-based application that enables process analysts to create and customize business processes. These processes are contained within an Oracle BPM project. Business Process Composer enables process analysts to easily collaborate with process developers who use Oracle BPM Studio to create process-based business applications.
See the following section for more information on the use cases for Business Process Composer.
There are three typical use cases for Oracle Business Process Composer:
Create, edit and deploy projects based on project templates.
Project templates are created in Oracle BPM Studio and are stored within the Oracle BPM Metadata Service partition. Using Business Process Composer, you can use these templates to create new or modify existing business processes.
You can then re-publish them to the Oracle BPM Metadata Service partition or deploy them to the Oracle BPM run time.
See Section 4.3, "Introduction to Project Templates" for information on using project templates in Business Process Composer. For information on creating project templates see the Oracle BPM Modeling and Implementation Guide
Create process blueprints.
Process blueprints are the first draft of a business process. They allow you to create abstract definitions of your business processes. These processes are included within a basic Oracle BPM Project that can be shared between Oracle BPM Studio and Business Process Composer.
However, process blueprints do not contain any of the implementation details required for an Oracle BPM application. Process developers can use Oracle BPM Studio to add the required implementation.
From Business Process Composer, you can publish the project to the Oracle BPM MDS partition where process developers can add the required technical implementation using Oracle BPM Studio.
Edit business rules for in-flight processes
You can use Business Process Composer to edit Oracle Business Rules in a running application. Oracle Business Rules enable you to define business policies within your process using the business rules task. You can easily change these policies at run time without having to remodel your business process or redeploy your business application.
Oracle Business Process Composer is a collaboration tool that enables process analysts to easily interact with process developers. It provides a user-friendly interface for creating process-based business applications based on project templates. These templates are created using Oracle BPM Studio.
Business Process Composer also provides an environment for creating process blueprints. Process blueprints are implemented as part of an Oracle BPM project and can easily be shared with process developers who are using Oracle BPM Studio to implement business processes as part of a business application.
The following sections describe typical scenarios by showing the interactions between different Oracle BPM components and the persona, including process analysts and process developers. However, the exact workflow you use depends on your business needs. There may be multiple iterations where process analysts and developers collaborate to create and refine a business process.
Figure 3-1 shows a typical workflow for using Oracle BPM Studio at the beginning of the development cycle to create process templates. These templates are used to create new Oracle BPM projects. These projects can edited by process analysts using Business Process Composer.
Figure 3-1 Using BPM Studio to Create Project Templates
The following steps describe each stage of this workflow:
Create a project template using Oracle BPM Studio (process developer)
Publish the project template to the Oracle BPM Metadata Service (MDS) partition (process developer)
Create a project based on a project template using Business Process Composer. (process analyst)
Edit the processes within the project based on the edit policies defined in the template (process analyst).
Validate the project (process analyst).
Deploy the project or return the project to the process developer.
Deploy the process directly to Oracle BPM run time (process analyst, business administrator). This may require an approval workflow.
Republish the project to the Oracle BPM MDS partition. (process analyst) Republishing the project enables you to share it with other process analysts or with process developers who are responsible for implementing your business processes within an overall application.
Export the project as an SAR file (process analyst). This file can be deployed to Oracle BPM run time (process administrators).
Figure 3-2 shows a typical workflow for using Business Process Composer to perform the initial process modeling stages of the application development life cycle. This workflow involves using Business Process Composer to create project blueprints which can be opened in Oracle BPM Studio where process developers complete the implementation.
Figure 3-2 Using Oracle Business Process Composer to Create Project Blueprints
The following steps describe each stage of this workflow:
Create blueprints using Business Process Composer (process analyst)
Publish the project containing the process blueprint to the Oracle Metadata Service (MDS) repository (process analyst)
Open the project in Oracle BPM Studio (process developer)
Implement the project as part of a process-based business application. (process developer)
Deploy the project to run time or save as a project template
Deploy the process to run time (process developer, business administrator), or
Save the application as a project template (process developer
Export the project as a SAR file (process analyst), which is then deployed to Oracle BPM run time (business administrator).
Figure 3-3 shows the workflow for creating and deploying a process-based business application, then using Business Process Composer to edit the Business Rules at run time.
Figure 3-3 Using Oracle Business Process Composer to Edit Oracle Business Rules at Run Time
Model your business processes and create a process-based business application using Oracle BPM Suite. This can include a combination of the workflows defined in the previous sections. (process analyst / process developer)
Deploy the application to Oracle BPM run time. (process analyst / process developer)
Edit business rules during run time using Business Process Composer (process analyst).
Before signing on to Business Process Composer your business administrator must provide the following:
URL: The location of your Business Process Composer installation.
Username: The username you use to access Business Process Composer.
Password: The security credential you use to access Business Process Composer.
Note:Oracle Application Server Single Sign-On is enabled by default in Oracle BPM Suite. OracleAS Single Sign-On enables you to use one sign on session to access multiple web-based applications. If OracleAS Single Sign-On is enabled and you have previously signed on to another application, the Business Process Composer sign on screen may not appear.
The following procedures describe how to sign on to the Oracle Business Process Composer application.

Oracle Business Process Composer contains three separate UI elements for working with projects.
The project navigator enables you to create and access projects and view and edit project resources.
See Section 4.2.1, "Introduction to the Project Navigator" for information on using the project navigator and working with projects.
Business Process Composer contains two project-specific menus described in Table 3-3.
Business Process Composer also contains a separate toolbar for working with projects. This toolbar appears on the right side of the application window. The items displayed depend on the current edit mode of the project.
See Section 4.2, "Introduction to Project Editing and the Project Menu" for more information on the project toolbar and project edit modes.
Editors enable you to work with various elements of an Oracle BPM project, including processes and components of the business catalog. Editors are displayed in the center of the Business Process Composer application.
Each editor appears as a tabbed pane in the Business Process Composer application, allowing you to open multiple resources at the same time.
The different types of editors available in Business Process Composer are described in the following sections.
The process editor enables you to view and edit business processes. You can access the process editor by opening a process from the project navigator.
The editor window also contains a component palette. The exact components available depend on the following:
In projects based on project templates, the component palette contains BPMN flow objects and elements from the business catalog. This includes services, Human Tasks, and Oracle Business Rules that are defined by the project template.
In projects containing process blueprints, the component palette only contains BPMN flow objects that can be used within your process.
See Chapter 5, "Working with Processes and the Process Editor" for more information.
The Activity Guide editor enables you to view, create, and edit milestones within an activity guide. You can access the Activity Guide editor by opening a milestone from the Oracle BPM Project navigator. See Section 6.12, "Using Guided Business Processes to Set Project Milestones".
The Human Task editor enables you to create and edit human tasks that are stored as part of the business catalog. See Chapter 8, "Working with Human Tasks" for more information.
The business rules editor enables you to view and edit Oracle Business Rules. You can access the business rules editor by opening a business rule from the project navigator. See Section 9, "Using Oracle Business Rules" for more information.
The data associations editor enables you to define the input and output for flow objects that contain implementations. To access the data associations editor, click the Data Associations button in the process editor.
See Section 7.2, "Working with Data Objects and Data Associations" for information on using data associations.
The expression editor enables you to define the expressions used within data associations and conditional sequence flows. See Section 7.4, "Introduction to Expressions" for information on using expressions and accessing the expression editor.
Business Process Composer contains additional editors for viewing and editing other project components. These appear in the lower portion of the application window.
Note:These editors are not displayed by default. They appear after performing actions related to each window. However, you can display them manually by clicking the Restore Pane icon in the lower right corner of the Business Process Composer application.
The project and process browsers display any validation errors for each individual process or the whole project. See Section 4.4.6, "How to Validate a Project" for more information on project validation.
The documentation editor enables you create and edit documentation for your processes. See Section 5.5, "Documenting Your Process" for more information.
The approval workflow browser displays the status of a project deployed to Oracle BPM run time. See Section 4.5, "Introduction to Project Deployment" for more information.
