Sybase WorkSpace

You define a BPM with the Sybase WorkSpace Business Process language when you want to design business processes and implement them using Business Process Service in Sybase WorkSpace.

• Top-Down Design
  A business analyst designs a model using the Analysis process language because he wants to have a global perspective on the processes of an enterprise, and a developer recovers this model to automate some of its processes.
• Importing Existing Services
  A developer recovers a model (either from an Analysis model or from BPEL files) where he wants to automate processes. To do so, he needs services and he knows existing services are available in the WorkSpace environment.
• Importing EJB or Java Web Services
  A developer designs and generates EJB or Java Web services in an OOM. He then wants to import them as service providers into a BPM in order to reuse them for automating processes in his orchestration BPM, he does not need any other type of services.
• Importing BPEL Files
  A developer wants to implement in WorkSpace an already defined orchestration process. He can use PowerDesigner as a bridge for importing BPEL files into the Sybase WorkSpace Business Process.
• Services
  In Sybase WorkSpace, a service is an interface to an external application or a business process. BSM (Sybase Base Service Model) is the native language used to describe a service. The BSM file contains the description of the entire Web service expressed by several port types. Each port type defines different operations. Sybase WorkSpace Business Process supports the following types of Web service operations:
• Business Processes
  A business process is a particular service implemented by the orchestration of other services including several activities linked by a graph. This graph defines the choreography of the Process. The business process may have fault, compensation, and timeout handlers that are not linked to the main choreography.
• Variables
  Variables are named data type instances that are accessible by all activities within a business process definition. Variables can have simple data types (string, integer, float, or boolean) or XSD complex data types.
• Partner Links
  You design partner links using organization units in the business process model.
• Service Invocation
  Services represent the interaction with internal and external applications, such as a database, Java applications or an ERP system. A service may contain several interfaces and each interface may contain multiple operations. Each operation has a schema in the service that defines the operation inputs and outputs. A service interaction represents an activity that invokes a service operation of the following type:
• Interface Activities
  Receive and Send activities are interface activities. The first time you create a receive or a send activity, a new service provider called ThisService is created, containing a Default service interface that contains all the operations created automatically for <<Send>> and <<Receive>> business processes.
• Assign Activities
  An assign activity is a sequence of atomic assign tasks. An assign task is an XPath expression that copies value from a variable to another variable. The assign task can be: a regular assign for setting the value of a context variable, a Get environment variable or a Get process Id that copies its value to a context variable, a Graft that adds nodes to an XML tree or a Prune that removes nodes from an XML tree.
• Split-Join Activities
  A split is a point in the business process where a single activity splits into two or more parallel activities. A join is a point in the business process where two or more parallel activities converge into a single common activity.
• Complex Activities
  A complex activity is made of atomic activities. Complex activities can end normally, after a timeout event, or after a fault event. The complex activity catches exception events (exception, compensation, or timeout) by using exception handlers, compensation handler and timeout handler.
• Loop Activities
  A loop activity is a complex activity with iterations.
• Event Handling Activities
  Events happen only within top-level process and complex activities. The different types of event handling activities are: exception, timeout, and compensation handling.
• Delay and Terminate Activities
  A delay activity allows the user to define a pause on the runtime processing and the delay for continuing the runtime processing.
• Sequence Flow from Activities
  A sequence flow is a control flow between activities. The link goes from a fixed out anchor in the source object to a fixed in anchor in the target object. Some objects like Start, Choice, Split, and complex activity may have more than one output coming from the same anchor. SingleRule may have more than one output going out, each one from a specific anchor. The remaining activities may have only one sequence flow going out from one anchor except terminal activities.
• Correlations
  A correlation is a set of identifying properties used by Sybase WorkSpace engine to identify the instance of a business process concerned by a received or a sent message.
• Switching to Sybase WorkSpace Business Process Language
  You can change the target language of an imported BPEL file or an Analysis model in order to design for Sybase WorkSpace Business Process. To do so, you can generate a model with the Sybase WorkSpace Business Process language or you can change the target language of the model.
• Importing WorkSpace Services
  The Import WorkSpace Services feature allows you to import any type of service as a service provider from a selected WorkSpace project to the current BPM. You can import business process services, database services, EJB services, Java services, message services, SOAP services, and transformation services.
• Invoking WorkSpace Services
  When you change the target language of your BPM from Analysis to Sybase WorkSpace Business Process you can rapidly implement <<Undefined>> business processes by invoking different types of services supported in Sybase WorkSpace.
