If you have any specific questions how to make your DFD work and render in an applet, ask a (much more) specific question.
But to be honest, if you cannot frame a more specific question after researching those links, I would recommend you look to a career in some field other than programming.

Data flow diagram - missing information stores

I am creating data flow diagrams using sql developer data modeler. Often, the information stores that I created and used in the Data Flow Diagrams in the process model are simpy gone when save, close and reopen the model. Even the XML files on the disk are gone. I am using version 2.0.0 build 584. Any idea why this is happening?

Hi,
There is a SQLDeveloper version 2.1.1 (Patch 1) out there.
You could try with that one, just in order to see whether your problem still persist.
If so, let is know.
Cheers!!

How Make a software Design Data Flow Diagrams (DFD)..?

I want a build up software for design DFD (Data Flow Diagrams). Can you help show to me a simple script for design DFD (Data Flow Diagrams). Thanks for all..
My mail : [email protected]

-Also the problem is how to do various validations of objects(line, oval, process) and move these objects using mouse? Which all specific events are needed ?This will help you [http://java.sun.com/docs/books/tutorial/uiswing/painting/step3.html]
-Another problem is how to have mutiple windows framework in applet. By clicking on the process another level corresponding to the process(i.e. its sub-process) will open?I think JInternalFrames would do.
I general please refer to [The Swing Tutorial|http://java.sun.com/docs/books/tutorial/uiswing/], it has answers to many (all) swing related problems. Go through it.
Thanks!

How Can I include a logical data model in a Data Flow Diagram?

Hi,
I have done a logical data model and now, I want to include it in a data flow diagram. I do not know which element I should use to make this relation.
Thanks,

Hi,
you need to create "Information structure" in the flow properties dialog and then can assign attributes to that information structure in its properties dialog

How to create Decision Node in Data Flow diagram under Process Model

Hi,
I am starting a new project and would like to use Oracle Data Modeler for my data flow diagrams and logical/relational diagrams. Could you please guide me how can I ask Decision question in data flow diagram. Ideallly i would like to create a Decision Node (diamond) in Data Flow diagram under Process Model with yes or no option.
Thanks in advance
JM

Hi JM,
may be you are looking for other notation. There is no dedicated decision node in data flow diagramming.

I can't find it either. Pratgeek, what was the name of the application you used in Ubuntu? Is there a website for it?
probably a kind of necrobump, but i've been searching for flowchart drawing software, and found this topic.
well, mentioned tdfd is the part of software suite called TCM available at least in debian/ubuntu.
it appears to be really old, i could found only user guide and ubuntu/debian package pages on the web, but it appears to be working quite well.
i've installed it on my ubuntu machine just half an hour ago, but it seems to be at least worth to play with, and i'd even make a PKGBUILD if i like it.

How to analyse the date flow diagram

hi guys,
my question is how to analyse in detail the data flow diagrams and functional and technical spes. how can i understant in detail.
regards,
manju

Hi,
Data flow diagram will show you the flow of the data from the Source System till the data target. It will give you the details of the Data Source, Info Source and Info Provider etc...
Functional Spec gives you the requirement of your company, I mean the fields they need for a particular reports and tables they have used etc... All you have to do is compare the fields you have in your data sources and finout which fields need to be added to the data sources or do you need to go for a new custom data source etc.. and prepare a Gap analysis Document. When You put the details of the data sources till the Info Provider I mean the TRs and URs etc.. in a document it becomes your Tech Spec.
Hope it helps...

Losing source-target mapping from a data flow diagram process

Hi,
When I reload a model design from an xml repository, I am losing source-target mappings from a data flow diagram process. I wonder why.
The way it goes is:
- I define a data flow diagram with information stores, processes, and flows.
- Information structures are defined from the flows and the information trickles down to processes and information stores.
- In a process, I define Source-Target Mapping by selecting a target element and then selecting the source element(s).
- I save the whole model.
- So far, the Source-Target Mapping keeps the association between target and source elements.
- If I exit from Data Modeler, the next time I reload the saved model, the Source-Target Mapping target to source elements associations are lost!?
Does anyone have the same issue or would know how to resolve it?
Thanks,
/Mario

Data Models and Data Flow diagrams.

Hi Gurus,
Can anybody brief me the concept of Data Models and Data Flow Diagrams and their development with illustrations. And is it a responsibility of a Technical or a Functional consultant..i.e to translate Business requirements and functional specifications into technical specifications, data flow diagrams and data models.
Your valuable answers will be rewarded.
Thanks in advance.

Hi,
Concept of Data Models
Data model or Data modelling is basically how you define or design your BW Architecture based on Business requirements. It deals with designing and creating a effcient BW architecture sticking to standard practices.

Data Flow Diagrams
This show the path of data flow for each individual object in BW. How data dets loaded into that object and how it is going out of the object etc.
Right click on the data target > show data flow .
It shows all the intermdeiate layer through which data comes into that particular object.
Responsibility of a Technical or a Functional consultant
This is done genrally in the designing phase itself by a Senior Technical Consultant with the help of a Functional consultant or a Techno=Functional consultant interacting with Business.
Hope this helps.

SSIS Data Flow task using SharePoint List Adapter Setting SiteUrl won't work with an expression

Hi,
I'm trying to populate the SiteUrl from a variable that has been set based on a query to a SQL table that has a URL field. Here are the steps I've taken and the result.
Created a table with a url in it to reference a SharePoint Task List.
Created a Execute SQL Task to grab the url putting the result set in a variable called SharePointUrl
Created a For Each container and within the collection I use the SharePointUrl as the ADO object source variable and select rows in the first table.
Still in the For Each container within the Variable mappings I have another Package Variable called PassSiteUrl2 and I set that to Index 0 or the value of the result set.
I created a script task to then display the PassSiteUrl2 variable and it works great I see my url
This is where it starts to suck eggs!!!!
I insert a Data Flow Task into my foreach loop.
I Insert a SharePoint List Adapter into my Data Flow
Within my SharePoint List Adapter I set my list to be "Tasks", My list view to be "All Tasks" and then I set the url to be another SharePoint site that has a task list just so there is some default value to start with.
Now within my Data Flow I create an expression and set the [SharePoint List Source].[SiteUrl] equal to my variable @[User::PassSiteUrl2].
I save everything and run my SSIS package and it overlays the default [SharePoint List Source].[SiteUrl] with blanks in the SharePoint List Adapter then throws the error that its missing a url
So here is my question. Why if my package variable displays fine in my Control Flow is it now not seen or seen as blanks in the Data Flow Expression. Anyone have any ideas???
Thanks
Donald R. Landry

Thanks Arthur,
The scope of the variable is at a package level and when I check to see if it can be moved Package level is the highest level. The evaluateasexpression property is set to True. Any other ideas?
I also tried to do the following. Take the variable that has the URL in it and just assign it to the description of the data flow task to see if it would show up there (the idea being the value of my @[User::PassSiteUrl] should just show in the
description field when the package is run. That also shows up blank.
So i'm thinking its my expression. All I do in the expression is set [SharePoint List Source].[SiteUrl] equal to @[User::PassSiteUrl] by dragging and dropping the variable into the expression box. Maybe the expression should be something
else or is their a way to say @[User::PassSiteUrl] = Dts.Variables("User::PassSiteUrl2").Value.ToString()
In my script task I use Dts.Variables("User::PassSiteUrl2").Value.ToString() to display
the value in the message box and that works fine.

Hi Pavan,
you need to make the process composite and then go to diagram and create process details.

Design and save workflow diagrams using flex

Hi,
I am new to flex..I need to design a workflow diagrams using flex and save the information..Could you please help me on this..
Actually what exactly i want is..
In my project we have some jobs..Job is bunch of scripts..These jobs will run in different hosts(Server).In my project we have a provision to run these jobs in order in different hosts.But not for running the scripts in perticular sequence.
For example::
We have a,b,c,d,e,f jobs..
1) these jobs run in order if we select one check box.This provision is there.Order means after a runs b should run.after b is done c should run and so on..
2) there is another senario like.
After a job runs b,c should run parallel and these 2 are done d shold run..after it is done e,f,g shold run paralell..some thing like this..This is a sequence of scripts running in different hosts..For this we nned to desing a UI like work flow diagram.
In UI we show all jobs in data grid and user will drag the jobs and keep it an area and he connects all the jobs with some lines with arrow(to identify).There he should conncects the jobs in which sequence he wants to run the jobs.
For this need to design a diagram and save the data in the UI.From UI we have to capture the sequence of jobs and store the sequence in db..
Colud you plz provide me soltion for this..I am getting how to draw a flow diagram using flex and capture the sequence from UI and store the data in DB..
Please help me out in this issue..
Thanks in advance...

I am trying to create an image file with flex and want to save it only in a perticular directory ie., user should not be given any option to choose the location.Air application uses resolvePath where we can specify the path but donno how this can be achieved for a web-based application.
Is there any workaround for this?
Thanks.

Data flows are getting started but not completing successfully while extracting/loading of the data

Hello People,
We are facing a abnormal behavior with the dataflows in the data services job.
Scenario:
We are extracting the data from CRM end in parallel. Please refer the build:
a. We have 5 main workflows flows i.e :
   => Main WF1 has 6 more sub Wf's in it, in which each sub Wf has 1/2 DF's associated in parallel.
   => Main WF2 has 21 DF's and 1 WFa->with a DF & a WFb. WFb has 1 DF in parallel.
   => Main WF3 has 1 DF in parallel.
   => Main WF4 has 3 DF in parallel.
   => Main WF5 has 1 WF & a DF in sequence.
b. Regularly the job works perfectly fine but, sometimes it gets stuck at the DF’s without any error logs.
c. Job doesn’t stuck at a specific dataflow or on a specific day, many a times it strucks at different DF’s.
d. Observations in the Monitor Log:
Dataflow---------------------- State----------------RowCnt------LT-------AT------
+DF1/ZABAPDF
PROCEED
234000
8.113      394.164
/DF1/Query
PROCEED
234000
8.159      394.242
-DF1/Query_2
PROCEED
234000
8.159      394.242
Where LT: Lapse Time and AT: Absolute time
If you check the monitor log, the State of the Dataflow DF1 remains PROCEED till the end, ideally it should complete.
In successful jobs, the status for DF1 is STOP . This DF takes approx. 2 min to execute.
The row count for DF1 extraction is 234204 but, it got stuck at 234000.
Then we terminate the job after sometime,but for surprise it gets executed successfully on next day.
e. As per analysis over all the failed jobs, same things were observed over the different data flows that got stuck during the execution.Logic related to the data flows is perfectly fine.
Observations in the Trace log:
DATAFLOW: Process to execute data flow <DF1> is started.
DATAFLOW: Data flow <DF1> is started.
ABAP: ABAP flow <ZABAPDF> is started.
ABAP: ABAP flow <ZABAPDF> is completed.
Cache statistics determined that data flow <DF1>
uses <0>caches with a total size of <0> bytes. This is less than(or equal to) the virtual memory <1609564160> bytes available for caches.
Statistics is switching the cache type to IN MEMORY.
DATAFLOW: Data flow <DF1> using IN MEMORY Cache.
DATAFLOW: <DF1> is completed successfully.
The highlighted text in the trace log is not appearing in the unsuccessful job but, it appears for the successful one.
Note: The cache type is pageable cache, DS ver is 3.2.
Please suggest.
Regards,
Santosh

Hi Santosh,
just a wild guess.
Would you be able to replicate all the DF\WF , delete original DF\WF, rename replicated objects to original to DF\WF names(for your convenience)   and excute it.
Some time reference does not work.
Hope this should work.

Problem with context mapping and data flow in a FPM application

Hi All,
I am trying to develop an ESS application using FPM. For the same, the requirement is to see the history of an employee in the second view.
The first view has got just the overview information and the second one has got the detail. So, the records or the fields are the same on both the views.
As per the FPM guidelines, the Model is residing in the Fc component and the respective Vc components are using the model data accordingly.
I am executing the model in the Fc component calling the executable method in the interfaceController of the first view and then trying to display the output data of the BAPI in the first view which provides the overview information.This is working fine.
But when i am trying to map the same output node to the Table UI for the second view, the record size is coming zero and thus no information is available.
For the above issue, I am again executing the RFC in the InterfaceController of the second view to populate the records, which is incorrect as it is already executed and the data is available for the first view.
I request you to let me know the correct approach to Context mapping and data flow when using FPM-roadmap. Is their any standard method or approach available to deal with such requirements? Please let me know.
Thanks in advance.
Regards
DK

Hi Idhaya,
I model node is available in Fc and the Fc interface controller is being used in the first Vc and the second Vc.
So the idea is, as the executable method is generated in the Fc, so i have created a custom method to call the executable method in Fc, where the input parameter is getting passed and this custom method is finally getting called is the first Vc.
So , now my first Vc is ready to call the custom method in Fc and execute the RFC. Once the RFC is executed, the nodes in the Fc should get populated which is the ideal case.
And as the Fc is used as a component in the second Vc, the same node is available to the UI elements.
But, when I check the record size for the output node, it is always zero, for the second Vc.
Regards
DK
