Generate Data model from Class model

I am using JDeveloper uml features for a first time, so I am interested if there is a option that I can generate class model to the data model.
If I have class model and than when right-click select Generate , there is a option to generate data model from it.
But it is dimmed. Is there any precondition to achieve before this option become possible.
Thanks in advance .

The link you mentioned has the Prerequisites,
Do include all the jar in you path.
It will resolve all your issues.

How to generate data model summary report

Hi,sir,
How can I generate a summary report when I create a server data model in designer 9i as some software did.
I know CA Erwin or Sybase powerdesigner have a good report builder.
It is easy to use. How about designer 9i?
Any tutorial?

Hi,
It's look like you are assuming that an organizational model can be created from external data input via a report. If so, then your assumption is wrong. There is no standard way to create a org. model from external input.
As a standard practice SAP provided a report as mentioned in the previous reply. Using this report you can download ECC/R3 org. model into SAP CRM. This is the easy and best proven way of generating org. model in SAP CRM.
Please let me know, if you need any further clarification
Do not forget to reward if it helps

Error in generating data source from planning area

Hi experts! I have an error while making data source from planning area:
after the screen when i fill in the data source name (Window name: Generate export data source) i have the SYNTAX_ERROR Message:
Syntax error in program /sapapo/cl_im_extract_ex======cp
the main reason: the type /BI0/9A0IVWKNDGD is unknown
what you can suggest to solve this problem?
Thanks.

Dear Andrey Kudriavzev,
The reason is the program is trying to use the datatype '/BI0/9A0IVWKNDGD' which does not exist in the system.
Go SE11 to cross check if it exists. Check dataelement radiobutton -> enter /BI0/9A0IVWKNDGD -> Choose display option. You would need to create this datatype in the system. I feel there must some OSS Note related to this.
Search for an OSS Note. Raise one if you cannot find the relevant notes.

Naveen.

Can i generate java API from class files

I have only class files. Is it possible to generate the java API using the javadoc.If yes, pls tell me how can i do??

Also, Javadoc 1.4.2 will contain an unsupported option -Xclasses
that should allow you to do this. You must pass in class names
and use -classpath to find them. For com.package.MyClass
at /home/classes/com/package/MyClass.class,
you would run:
javadoc -Xclasses -classpath /home/classes com.package.MyClass
For mroe info, see:

SQL Developer Data Modeler for SQL Server 2008

I am not able to connect to my SQL Server 2008 from the SQL Developer Data Modeler. Although I do have jtds-1.2.jar on my machine and I can connect the SQL server through the SQL Developer, but still i'm not able to connect through the data modeler. I need to re-engineer and generate data model for some existing schemas.
Here is what I'm following:-
File->Data Modeler -> import -> Data Dictionary -> Add new connection -> JDBC ODBC Bridge -> Other Third Party Driver
now when I'm giving the JDBC URL and the Driver, It throws an error message stating that the driver could not be found.
Please let me know what I can do to solve this, any help would be appreciated.
Regards,
AVA

I'd try 1st to connect to the db from sqldeveloper (through jtds - no ODBC involved) and see if you can browse your db and issue sql statements in a worksheet. Then export that connection in xml format and import that from the modeler.

Why I cannot change the generated data source?

Hello all,
I have a generated data source from ODS, now I need to change something on it but the system only allow me to display it even I clicked the pen-glasses icon. Could anybody tell me how?
Thanks
Ryan

Hi Ryan,
You can't the generated data source from an ODS object, this is becasue ODS supplies delta from change log tables and the export data source / info-source structure should be same as of the change log table.
However you can change the generated data source-info source assignment of info-cube.
Hope it helps
Thanks,
Soumya

I can't create Entity Data Model Class directly from database

I have just installed odac beta (ODAC1120250Beta_EntityFramework) and Orace XE 11g for test.
I have Visual Studio 2010 on Windows 7 32bit.
The problem is that after updating odac I can't create ADO.NET Entity Data Model class. If I try, VS2010 wizard makes me choose if I want to generate from db or create an empty model. If I choose to generate from database, the next window disappers making me return to VS2010.
The workaround is to create an empty model and then update model from database. In this way it works.
Anybody has experimented the same?...
Best regards
Francesco

A couple of things you could try:
1. Install SP1 for Visual Studio 2010.
2. Do you already have an Oracle connection created in server explorer? If not, try creating one and then create the model.

Xcode, how do you take an app from an idea to a data model, data structure, or class structure?

Hey everyone!
I'm a beginner xcoder and computer engineering sophomore and have literally spent every hour of the past few weeks reading as much as I possibly can about becoming a developer.
I've found plenty of documentation, and guides on how to do very specific things in xcode and objective-C but am still looking for more information on one topic; how do you decide which data models/structures/controllers etc to use?
I mean, you personally. I've been looking for a resource on this and have not been able to find one. I just finished Apple's iOS Developers Guide and they mention "choosing a data model" but do not describe them in much detail.
The following is what is provided in the guide:
● Choose a basic approach for your data model:
● Existing data model code—If you already have data model code written in a C-based language, you
can integrate that code directly into your iOS apps. Because iOS apps are written in Objective-C, they
work just fine with code written in other C-based languages. Of course, there is also benefit to writing
an Objective-C wrapper for any non Objective-C code.
● Custom objects data model—A custom object typically combines some simple data (strings, numbers,
dates, URLs, and so on) with the business logic needed to manage that data and ensure its consistency.
Custom objects can store a combination of scalar values and pointers to other objects. For example,
the Foundation framework defines classes for many simple data types and for storing collections of
other objects. These classes make it much easier to define your own custom objects.
● Structured data model—If your data is highly structured—that is, it lends itself to storage in a
database—use Core Data (or SQLite) to store the data. Core Data provides a simple object-oriented
model for managing your structured data. It also provides built-in support for some advanced features
like undo and iCloud. (SQLite files cannot be used in conjunction with iCloud.)
● Decide whether you need support for documents:
The job of a document is to manage your app’s in-memory data model objects and coordinate the storage
of that data in a corresponding file (or set of files) on disk. Documents normally connote files that the user
created but apps can use documents to manage non user facing files too. One big advantage of using
documents is that the UIDocument class makes interacting with iCloud and the local file system much
simpler. For apps that use Core Data to store their content, the UIManagedDocument class provides similar
support.
I suppose my question boils down to, how do you decide which structures to use? If you can provide an example of an app idea and how its implemented that would be very helpful and much appreciated!
For example, to implement the idea of an app which allows users to progress through levels of knowledge of a certain subject and rewarding them with badges and such (this is not an actual app just a whim) how would one model that?
Thanks in advance for all your help!!!

Trial and error.
I wish I had a better answer for you, but that pretty much encapsulates it. There is some, but not much, good wisdom out there, but it takes a significant amount of experience to be able to recognize it. The software development community if currently afflicted with a case of copy-and-paste-itis. And the prognosis is poor.
The solution is to be brutal to yourself and others. Focus on what you need and ignore everything else. Remember that other people have their own needs and methods and they might not be applicable to you. Apple, for example, can hire thousands of programmers, set them to coding for six months, pick the best results, and have the end-users spend their own time and monety to test it. If you don't have Apple's resources and power, think twice about adopting Apple's approach. And I am talking from a macro to a micro perspective. Apple's sample and boilerplate code is just junk. Don't assume you can't do better. You can.
Unfortunately, all this takes time and practice. You can read popular books, but never assume that anyone knows more than you do. Maybe they do and maybe they don't. It takes time to figure that out. Just do your best, ignore the naysayers, and doubt other people even more than you doubt yourself.

Generate ER Diagram from Sql Data Modeler

Hi,
I want to use the Oracle Sql Developer Data Modeler to generate ER diagram for my schema. There are huge number of tables in this schema, so I would like to identify only those tables which need to be selected for generating my ER diagram.
Basically, I want only those table which are having relationship with other tables here. The reason being, if I select all tables in the schema then I would get those tables in the ER diagram which don't have any relationship with other tables.
Can someone please suggest writing queries which yield this from data dictionary?
Thanks.

Well, your requirement is based on the the database schemas having been designed with proper primary key and foreign key constraints in place. If they're not there then the database doesn't know about the relationships between tables, and such relationships are just theoretical (and as such usually controlled by the application that uses them).
Of course there are also tables that are used by applications for lookups and other reasons, so they're part of the application and should be included on ER diagrams, even if they have no direct relationship to any one table (or they could have relationships to many tables).
So, rather than try and write queries to figure out what tables are required, why not let the Data Modeller tool generate an ER diagram from the information that IS known about on the database, and then you can see if the relationships exist, or if they're missing and need manually putting on the diagram (or applying to the database).

Metadata from Erwin data model to BO Designer

Hi,
I have generated a CWM XML file from ErWin, that contains the physical table names of all tables in the model. I am using universe "metadata exchange" to convert this data model into a universe. The first time "create universe" is happening fine.
The problem is while updating the model.
There is a "owner" field specified in Erwin table. If thats left empty, the tables in the universe schema are generated as "unnamed_NNN.<TABLE_NAME>". (NNN is a number)
Obviously I have to remove the unnamed_NNN from the tables so that it will recognise the default database for the connection.
Say, the metadata has undergone some changes and we want to update the universe with new metadata. I used "metadata exchange" to update the universe from the model. At this time, it creates a new table and class with "unnamed_NNN.<TABLE_NAME>", instead of updating my TABLE_NAME class and object definition with the changed metadata.
This basically means update doesn't function as expected. Can anyone suggest if this is a limitation of the metadata exchange or am I doing something wrong ?

I am trying to do the same thing using ER/Studio and have the same problem.
In addition, the joins from the model are not being reflected in the universe.

Powerpivot Error on Refresh -- "We couldn't get data from the data model..."

I'm using Excel 2013 and Windows 8.1. I have a spreadsheet I've been using for over a year, and I've just started getting this error message when I try to refresh the data.
"We couldn't get data from the Data Model. Here's the error message we got:
The 'attributeRelationship' with 'AttributeID' - 'PuttDistCat9' doesn't exist in the collection"
Any idea how I can fix this problem? I haven't changed anything related to that particular attribute. All the data is contained in separate sheets in the workbook, so there are no external sources of data.
Thanks.
Jean

Thanks for all the suggestions.
I found a slightly older version of the spreadsheet that still refreshes properly, so I don't think I have any issues with the version of Excel or Power Query. (I've had this same error before, and I believe I applied the hotfix at that time.)
I think this problem started after I updated a number of the date filters in the pivot tables. I haven't made any changes to the data model, and the only updates I've made were to add data (which I do all the time), and to change the date filters on
the pivot tables.
As suggested, I added a new pivot table querying one table (the table with the attribute that shows up in the error message), and it worked fine. I can also refresh this pivot table.
Then I tried adding a pivot table which went against several tables in the data model (including the table in question). The pivot table seemed to return that data properly. However, when I tried to refresh it, I got the same error message ("we
couldn't get data from the data model...").
Dany also suggested running the queries one at a time to see which one is in error. Without checking all the pivot tables, it appears that any which use the table "HolePlayedStrokes" generate the error (this is the table with the attribute
mentioned in the error message). Pivot Tables without that particular table seem to refresh OK. Unfortunately, that is the main table in my data model, so most of the pivot tables use it.
Any other suggestions? I'd be happy to send a copy of the spreadsheet.
Thanks for all the help.

BIP Trial 11.1.1..6: Error while generating XML data in Data Model

Hello,
I have created a Data Model with a single query. After saving the DM and clicking on the XML icon to generate sample data, I get the following error:
The XML page cannot be displayed
Cannot view XML input using XSL style sheet. Please correct the error and then click the Refresh button, or try again later.
End tag 'span' does not match the start tag 'img'. Error processing resource 'http://localhost:7001/xmlpserver/servlet/xdo'...
*<table style='background=color: #d9e5ef; margin-top: 10px;' width='100%' cellspacing='0' cellpadding='0' border='0' summa...*
I have verified that the SQL runs without errors in SQL Developer using the same connection parameters as whats used in the DM.
There are no html tags/key-words etc being used in the sql our it's output.
Is there a a way to debug this? This is extremely frustrating. Especially since the same sql works without any issues in Oracle Reports.
Thanks,
Manish

ya i can understand we wont do the sql logic at the data model part as some time performance issue may come when comparaed to sql run in package and sql running in data model . so i have mostly done using package and i will just do select * from table in the data set of data model so i didn't face any issue's like this .
once check this tutorial may be you already
i use to create parameters like this i didn't face any issue
SELECT * from TEST where ID=:p_id

How to generate the java code of a table's data model by parsing it's FXML?

I have know how to create FXML file that describes a table. Meanwhile, according to [Oracle Tutorial|http://docs.oracle.com/javafx/2/fxml_get_started/fxml_tutorial_intermediate.htm#CACFEHBI], it is a best practice to implement a class that defines the data model and provides methods and fields to further work with the table.
However, It's rather cumbersome and time consuming to typing the code. So, is there any tools that can generate the java code of a table's data model by parsing it's FXML describe file?

Create sequence from Data Modeler?

Hi,
I started using SQL Developer Data Modeler to model my first APEX application, but there are one thing I don't understand.
From the logical model, I can create all my application model, but I don't find anywhere I can define thath my PK must be populated from a squence.
From APEX is a step in the wizard, creating the sequence and trigger, but If I model from Data Modeler, then, I "loose" this important feature common to mostly all my table objects.
There are something I'm missing?
Regards.

Data Modeler: Problems with importin from DDL and Designer

I have a few problems with importing models from Designer and DDL:
1. Can I import spatial indexes from Designer or DDL file? An index does appear in the model but it doesn’t seem to be a spatial index. When trying to import from database, the index doesn’t appear in the model at all.
2. Is it possible to import sdo_geometry data types from DDL file? I haven’t succeeded with it, instead the column's data type appears unknown.
3. Sometimes import from DDL files (that are generated with DM) failed with nothing appearing to the model. I haven’t figured out why that happens. I didn’t receive any error message, the model just opened empty.
4. DM doesn’t seem to recognize public synonym creation from DDL. View log gives the following message:
<<<<< Not Recognized >>>>>
CREATE PUBLIC SYNONYM TABLE1
FOR TABLE1
5. Sequences lose their properties when importing from Designer. They only have a name but but start with, increment by and min/max values are empty in DM. Importin from DDL works fine.
I’m using data modeler version 2.0.0 build 584

Hi Alex,
There is newer version of Data Modeler (3.0 EA2) and it is free
You can download it from here
