Short Class Assignment: IDL, Generated and Written Code Objektorienteret Middleware (OOMI)

Agenda Part 1 (after initial CORBA intro): A range of requirements are given Consider IDL needed Consider what tools to use to create stubs/skeletons Consider which files gets generated – and what they consist of Part 2 (after CORBA code intro): What do we need to code to complete Which steps must we go through? Part 3 (after Architectural Design intro): What are the potential problems in your original design? Would you do anything in another way? Is there anything missing in CORBA?

Part 1: Requirements -> IDL & Gen. Files A distributed Java server application needs to collets various vital signs from different C++ based embedded measuring stations Each Measuring Station has Station ID, a Station Type, and Measuring Frequency. Each measurement performed has Measure ID, Patient ID, a Measure Time Stamp, Attached Station ID Types of Measuring Stations Pulse/ECG (only the pulse for this exercise) Blood pressure Temperature Blood Gas level The Server should allow distributed PC clients to start and stop individual stations, as well as all stations at once Also the Server should allow PC clients to obtain data from individual stations (also getting a list of stations/station type) Also the Server should allow for getting live data as soon as they are available, and historical data from individual and/or all stations at once 1) Use 15 minutes for producing the IDL 2) Use 5 minutes to consider which tools to use 3) Use 5 minutes to consider which files gets generated and what they consist of

What are the potential problems in your original design? Or was it just perfect? Would you do anything in another way? Factory, Façade, DTO, Layering, Modules, Round-tripping Is there anything missing in CORBA? Is it possible to implement at all? 5) Use 5 minutes: Consider your design from earlier. Anything needs changing? Part 3: Architectural Considerations 6) Use 10 minutes: discussion in plenum
