Some ofthe sample SAS libraries might appear to be grayed out, but they are still available foruse.Typically, grayed-out SAS libraries appear for users in Europe and were originallyintended for use with SAS Enterprise Miner.1Start SAS OnDemand for Academics: Enterprise Miner and log on.2Select File  Open  Data.3Select Servers.4Double click SAS Apps.5Double click Libraries.6Right-click on the grayed-out SAS library that you would like to access and thenclick Assign.7Double click the SAS data set that you want to use.2930 Step 4. Review the Basics for Working with Data, Results, and ProjectsChapter 3Working with ProjectsSAS OnDemand for Academics: Enterprise Miner uses the SEMMA model to organizedata mining projects.Understanding Project Storage QuotasEach SAS OnDemand for Academics: Enterprise Miner user has a large project storagequota.

An e-mail message is sent to any user who has used 75% of their storage quota.If the project storage quota is reached, then SAS OnDemand for Academics: EnterpriseMiner stops functioning properly. To avoid this, consider deleting any unnecessaryprojects before reaching your quota to ensure that SAS OnDemand for Academics:Enterprise Miner continues to work properly.If you do reach your quota and then delete unnecessary projects to create more projectstorage space, then the last project that you were working with could be impacted. If theproject runs incorrectly after removing unnecessary projects, then you might need torebuild the diagrams for this project.Creating New ProjectsWhen you create a new project, you use the Create New Project wizard.

Step 3 of thiswizard enables you to select a SAS folder in which to store your project. Even thoughyou have the ability to browse in this step, accept the default project storage location:/Users/your-user-id/My FolderAccepting the default project storage location ensures that your projects can be accessedappropriately by SAS OnDemand for Academics servers.If you select Browse and attempt to store your project in a location other than thedefault, the following error is displayed:To correct this error, change the location where your project will be stored back to thedefault location: /Users/your-user-id/My FolderOpening Existing ProjectsTo find and open an existing project:1Start SAS OnDemand for Academics: Enterprise Miner.2Click Open Project.3From the Open Project window, open the My Folder folder.4Select the project that you want to open.5Click OK.SAS OnDemand for Academics: Enterprise MinerStep 4.

Review the Basics for Working with Data, Results, and ProjectsCreating Model PackagesWith SAS OnDemand for Academics: Enterprise Miner, users can create modelpackages (also known as SAS Package Files or .spk files). Model packages can be createdfrom any node in a diagram. Typically, you create a model package when you aresatisfied with your model and you want to preserve it or share it with someone else.In most cases, you create the model package from the last node of a process in adiagram.

This ensures that the model package includes the entire process flow.Differences between Project Model Packages and Exported ProjectDiagramsWith SAS OnDemand for Academics: Enterprise Miner, a user can create a modelpackage and send it as a SAS Package File (.spk), or export a diagram as an XML file(.xml). If a specific project takes a long time to run, then having the model package (withthe associated results) can be advantageous.Exported diagrams contain no results. After a project’s diagram has been exported as anXML file, it can be shared as an attachment in an e-mail message or by placing the fileon a shared network directory.

To use the shared file, it must be imported in to SASOnDemand for Academics: Enterprise Miner and then the appropriate path of thediagram would have to be run to produce results.Note that neither model packages nor exported diagrams include the actual data that isreferenced. To rerun the project, you must have access to the original data or use theLIBNAME statement that points to the original data if that data is stored on the SASserver.Sharing Homework AssignmentsThere are three ways that you can share homework assignments: either by creating andregistering a project model package, by sharing a project model package, or by sharing aproject diagram.Submitting Homework AssignmentsWith SAS OnDemand for Academics: Enterprise Miner, students can create and submitan entire project model package, or export a project diagram and share the exported file.Ultimately, the choice is up to the instructor.

The decision might be made based onwhether the instructor needs access to project results or diagram files.To Submit a Project Model Package to an Instructor1Create a project or open an existing project within SAS OnDemand for Academics:Enterprise Miner.2Highlight the appropriate node within a diagram.3Select Actions  Create Model Package.4In the Input dialog box, enter a name for the model package. To ensure that youchoose a unique filename, you might want to include your name or initials as partof the filename. This ensures that an instructor can distinguish one submittedmodel package from another.5From the Project Panel on the left side of SAS OnDemand for Academics:Enterprise Miner, expand the Model Packages folder.3132 Step 4. Review the Basics for Working with Data, Results, and ProjectsChapter 36Right-click on the appropriate model and then click Save As.

You are prompted tosave the model as a SAS Package File (.spk).7Share the appropriate .spk file with your instructor (through e-mail or through ashared network directory).To Submit an Exported Project Diagram to an Instructor1Create a project or open an existing project within SAS OnDemand for Academics:Enterprise Miner. Ensure that your project includes a diagram.2From the Project Panel on the left side of SAS OnDemand for Academics:Enterprise Miner, expand the Diagrams folder.3Right-click on the appropriate diagram and then select Save As.

Save thediagram as an .XML file. To ensure that you choose a unique filename, you mightwant to include your name or initials as part of the filename. This ensures that aninstructor can distinguish one submitted diagram from another.4Share the .XML file with your instructor (through e-mail or through a sharednetwork directory).CollaboratingStudents can collaborate with each other while using SAS OnDemand for Academics:Enterprise Miner in one of two ways:by saving an entire project as a model package and then sharing the modelpackageby exporting project diagrams as XML files and then sharing those files with eachotherThe choice might be determined by whether the students need to share the results of aproject. Exported diagrams do not contain results while model packages do.Note: Neither model packages nor exported diagrams include the actual data that isreferenced.

To rerun the project, you must have access to the original data or have theLIBNAME that points to the original data if that data is stored on the SAS server.To Share a Project Model Package1Create a project or open an existing project within SAS OnDemand for Academics:Enterprise Miner.2Highlight the appropriate node within a diagram.3Select Actions  Create Model Package.4In the Input dialog box, enter a name for the model package.

Finding Help for Common Problems 33Note: The user who receives the model package can start SAS OnDemand forAcademics: Enterprise Miner and choose File  Open Model Package to open thepackage and view the diagram and results. The user is unable to make any changes orrerun the diagram nodes. However, the user can choose Action  Recreate Diagram tore-create the diagram within the current project. Once the diagram is re-created, theuser has a working copy of the diagram, just as if they imported the appropriatediagram.xml.

The user must run a diagram path to produce any results.To Share a Project Diagram1Create a project or open an existing project within SAS OnDemand for Academics:Enterprise Miner.
