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!!

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

I am still having problems getting my source to target mappings to save after I apply the fix described in this thread. Any thoughts?

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

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.

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

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

i recently switched to archlinux from ubuntu.there is ubuntu there was tdfd for creating Data Flow Diagrams but i am not able to find any alternative for archlinux.
Could anyone suggest me the software to be used.
Thanks

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...

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!

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

Flow diagrams

Hi, I know that this question shoudn' t be on this forum but there are many people who can help me so please understand me.
I have developed an app for java and now I have to amke some flow diagrams like data flow diagrams (from level 0 to 2) system flow diagrams, state diagrams, transition diagrams (sorry if the name isn't correct in English).
What Im looking for is a web page or someting with information on how to do these diagrams (tutorials, examples, etc).
Thanks for your help. Bye!

UML 2.0 (Unified Modeling Language) is what you are looking for. Googling UML and/or the types of diagrams you need
should give you more hits than you can handle.
You can also check Safari, Amazon, etc. for many UML specific books, beginner and beyond.
Your forum transgression could be forgiven since it can be argued that being able to model the system you are trying
to design is a necessary skill for any programmer/engineer - Java or otherwise.
But in this case, I think it is especially relevant to Java since it is such a strongly object oriented language.
The only thing I would note is that the diagrams you are tasked with making should have been done before writing the app.

How to find the data flow for a given module.

Hi ,
Is there a way to find the data flow for a given module(Example AR,AP,......).
I mean are there any predefined document other than user guides that explains with data flow diagrams(including the tables involved).
Any help would be greatly appreciated.
Thanks & Regards,
Naveen.

No such public document available from Oracle unless from Oracle Education.
for some specific operation you can check Process tab inside Oracle Application which shows the data flow as part for workflow process.

The Boot Configuration Data file is missing requires Information

My ideapad U310 doesn't boot any more after the boot procedure was interrupted by power outage.
A blue screen shows the following:
Recovery
Your PC needs to be repaired
The Boot Configuration Data file is missing some required information.
File: \BCD
Error Code: 0xc000000d
You'll need to use the recovery Tools on your installation Media. If you don't have any installation media (like a disc or USB device), contact your system administrator or PC manufacturer.
Press ESC for UEFI Firmware Settings

I can only make one suggestion. Boot from usb Recovery flash drive and hope that the startup repair will do their magic to your unit.

HP Stream 7 The boot configuration data file is missing some required information

I have an HP Stream 7 tablet. When I open it up it shows a blue screen with the error "The boot configuration data file is missing some required information." Can anyone help as I can't get into the tablet to solve the error!

Hey @PaD2 ,
Welcome to the HP forums.
I understand you're unable to boot up your Stream 7 tablet.
Try accessing the recovery partition by holding the volume down button and power button at the same time. Please excuse my ignorance, as exact information on accessing the recovery manager appears to be unavailable for this exact model. If the down button doesn't work, up should get you in.
Once in the recovery manager you should be able to select Troubleshoot > Startup repair.
If the startup repair does not fix the issue I would suggest trying the full system recovery option, which you should find under Troubleshoot > Advanced.
Thanks.
