This project is maintained by the Data Administration and Data Quality Branch at SSA. AppWrapperĪn AppWrapper is used to pass a SCAPI Application object between the various classes while eliminating the need for users of the ERwinApiWrapper library to add a reference to the SCAPI COMlibrary. Transactions are completed by calling either Commit() or Rollback(). ModelTransactionĪ ModelTransaction class can be used to group multiple operations together, so they all either succeed or fail. Closing a ModelMartConnection will also close a remote model. When finished, the Close() method must be called for local models, but not for remote models.
Models can be manipulated using methods or by accessing the SCAPI objects directly.
ModelĪ Model class encapsulates the SCAPI objects associated with an ERwin model. Finally, Close() must be called to close the connection. After the connection is open, then methods such as OpenModel() can be called. To use a ModelMartConnection, it must be provided a ModelMartConfiguration and the Open() method must be called. Local operations are performed via the OpenModel() or AddNewModel() methods and remote operations are performed via the OpenModel() and SaveMMModelToLocal() methods on the ERwinApiWrapper's ModelMartConnection property. The ERwinApiWrapper class is the starting point for all local and remote operations. Model m = ("MART://MART/DIRECTORY/MODELNAME") Īpp.ModelMartConnection.SaveMMModelToLocal(m, "test.erwin") ModelMartConfiguration configuration = new ModelMartConfiguration("server", "username", "password") ĮRwinApiWrapper app = new ERwinApiWrapper(configuration)
#Erwin data modeler license key code
The following sample code exemplifies basic local model usage. The default location is C:\Program Files\erwin\Data Modeler r9\EAL.dll
To apply, complete this form using your email account provided by the academic institution promoting the use of erwin as part of the curriculum. Also Important Change the target architecture to match your ERwin installation (either 圆4 or x86). Students and teachers of approved accredited academic institutions can apply for the Academic Edition of erwin Data Modeler to use on their personal computers.Important Open ERwin Data Modeler before trying to use the ERwin API.The ERwin client must be installed and running with a valid license. The code simply needs to be added as a dependency of whatever application needs to use the code. Note: not affiliated with or endorsed by ERwin Data Modeler Getting Started NET Framework library that provides a simple set of classes to manipulate local and remote ERwin Data Modeler data models.
