Creating a logical data model in BPA 11g

Hi,
Can we create a logical data model in BPA 11g? If we can do that can it be moved over to the BPM environment seamlessly. I was under the impression that during the modelling exercise a business analyst would develop process models and logical data models in BPA & the turn it over to IT developers who will pull these models in and develop the implementation. Is that how it works?
Thanks.

You can create a logical datamodel in BPA suite. The sample applicaton has an example of that: the quote to cash datamodel. There are different types of datamodels that you can create (business objects, entities etc).
Examples of datamodels can be found in the sample: OBPA Release 11. quick start.
The datamodels can't be imported I think, the process models can. You can either import them into Oracle BPM Studio (as executable BPMN) or into Oracle SOA Suite (transforms it into BPEL) with JDeveloper.

Lonneke

Creating Time dimension in BW data model. - like seen in logical data model

Hello all,
I have been struggling with this thing and I am looking for some help from anyone on this forum.
We are trying to create a logical data model of our bw system. We are going live next month with Student module for universities. We have multiple Infocubes and DSO and since there is so much crossing over in between them most of the reporting is done on infosets.
One of the thing we were thinking; is it possible to create something like a common time dimension table for every infoprovider. Basically when we are providing the reports to the end user can we give them a drop down menu which gives a time frame for reporting rather than selecting.
Example: Like can we create something which looks in the drop down like current month data, last months data, three months ago, four months ago, five months ago, one year ago, two years ago. Can we make like these data slices in our cube and deliver it to the end user?
We have in our cube a few date infoobjects, like receipt date, decision date, cancellation date and like wise.
Please let me know if any one has done any similar thing, it will be very helpful.
Thank you so much in advance.

if you add your common time dimension to your data model, first identify for each infoprovider the time against which 'current month' and other frames should be applied and map them to your dimension.
just a question... are you not using time dimension in cubes ? ideally this should be your time dimension llinking all.
when you use time dimension which uses 'current month' , 'current year' , you will have to address their historisation as well. (because current month now will not be so current after 2 months).
so in data load procedure every day these values need to change (meaning drop and reload).
and routines to populate these values based on reporting date.

Repeating groups in logical data model

Hello,
I am trying to create a logical data model where the following rules are applied:
Each Renovation Job may include one or more Rooms.
Each Room can be included in one or more Renovation Jobs.
Each Room Renovation may have one or more Renovation Types
Each Renovation Type may be associated with one or more Room Renovations
The following is a list of tables and their values I have created to support the above (Renovation_Jobs, Room_Codes, Renovation_Type_Codes, Renovation_Room_Types). I put tables "Renovation_Jobs" + "Room_Codes" + "Renovation_Type_Codes" having a one to many relationship to intersection table "Renovation_Room_Types". There are repeating groups in "Renovation_room_type" table (Renovation_job + Room_codes), does this mean I have to create another intersection table for this as well?
Renovation_Jobs:
1
2
3
Room_Codes:
Kitchen
Bedroom
Living Room
Renovation_Type_Codes:
Paint
Replace carpet
Replace light fixture
Renovation_Room_Types:
1     Kitchen     paint
1     Kitchen     Replace light fixture
1     Bedroom     paint
1     Bedroom     Replace carpet
1     Bedroom      Replace light fixture
1     Living room     Paint
1     Living room     Replace carpet
2     Kitchen     Paint
2     Kitchen     Replace light fixture
3     Kitchen     Paint
3      Bedroom     Paint
3     Bedroom     Replace carpet
Any help would be appreciated.
thanks

Each Renovation Job may include one or more Rooms.
Entities - Renovation Job Room, Room Renovation (intersection between Renovation Job & Room)
Each Room can be included in one or more Renovation Jobs.
Covered by Room Renovation
Each Room Renovation may have one or more Renovation Types
Entities - Renovation Type, Renovation Room Type
Each Renovation Type may be associated with one or more Room Renovations
Covered by Renovation Room Type
There are repeating groups in "Renovation_room_type" table (Renovation_job + Room_codes)That's just your foreign key to Room Renovation, isn't it?
You said that each renovation type may be associated with one or more room renovations.

Identify Entities for Logical Data Model

Hi,
I donno exactly this is the correct forum for this question. I believe there are database experts here to help me on this.
I am in confusion that, phsically the data can be saved in a set of tables (4-5 tables). But different views (User Interfaces) and reports can be created from these tables.
Assume that,
View1 - Uses all tables
View2 - uses only 3 tables
View3 - uses only 1 table
Report 1 - uses only 2 tables
Report 2 - uses only 4 tables
Should my Logical Data Model reflect all these view1, view2, view3, Reprt1 and Report2?
How exactly do we need to identify the entities for Logical Data Model?
Could you please any one help me on this?
Thanks & Regards

Need tips to build a Logical data model

Hey Gurus,
1) I need some tips in building a logical data model.
I have reviewed a functional spec and listed all the fields required in a report. I now looked into datasources( extractor) in R/3 side which can bring most of these fields but there are certain characteristices which are not part of this extractor, what i have found out is that they are the attributes of a master Data <u>but there are still some more fileds which are not part of the extractor and attributes of a master data</u> , so now how do i bring the data for those fieds????? <b>Do I have to enhance the extractor or do i need to enhance the Masterdata???????</b>
How do i decide whether to enhance the extractor or the Master data?? Experts please give me some tips out of ur experiences so that i can decide on what to enhance.
2) Assume that i have an extractor which can bring me all the fileds required in a report. Now how do i build a logical data model????????
is it like

1. Use XML Spy Enterprise edition editor.
2. Goto www.xmethods.com, select service you want to create demo of.
3. Get its WSDL url.
4. In XML Spy SOAP menu there is a command 'create new soap request'. Press that, enter the WSDL url. You will get a SOAP request.
5. Edit SOAP request parameters. Type parameters of your choice.
6. Press 'send request to server'. You will get SOAP response. It will contain result from the requested method.
7. Paste that response inside a JSP.
8. Write a local method which will return same response (remote method's return value) that came from remote web service.
9. Paste that method inside abovementioned JSP. Replace static response in that JSP with the response generated by local method. The method parameters will come from client's SOAP request. Parse SOAP request to get request parameters. (As it's your demo, you know the data types of the parameters).
10. Host that JSP on any Servlet/JSP engine.
That makes your Web Service.
You can use any package like Aapche SOAP, AXIS or JAX-RPC to generate a SOAP client. Use the URL of JSP(step 10) as "endpoint".
Note: Indside JSP make sure that there in no endline and carriage return character. Otherwise it won't be a valid SOAP response.
Good luck.

Logical data model

hi
I am currently making a white paper on rdbms and logical data models. Can anyone point from where can I get a logical data model for the telecommunication industry for data warehousing purposes ???

Kunal Choksi

Instead of using exploit like that, I prefer to find a way to represent reality more generally. In the following model for example it is possible to specify also the reason for the end of a marriage ( divorce,death of partner, annulment, alimony ) in the right table.
CREATE TABLE PERSONS (
     PERSON_ID NUMBER PRIMARY KEY,
CREATE TABLE MARRIAGES (
     MARRIAGE_ID NUMBER PRIMARY KEY,
     BEGIN_DATE DATE NOT NULL,
CREATE TABLE OLD_MARRIAGES (
     MARRIAGE_ID PRIMARY KEY,
     CONSTRAINT DIVORCES_MARRIAGE_FK
          FOREIGN KEY (MARRIAGE_ID) REFERENCES MARRIAGES,
     CAUSE_OF_END VARCHAR2(N) NOT NULL, --<--- DIVORCE,DEATH,...WHATEVER
     END_DATE DATE NOT NULL,
CREATE TABLE ACT_MARRIAGES_RELATIONS (
     PERSON_ID NUMBER NOT NULL,
     CONSTRAINT ACT_MARRIAGES_PERSON_FK
          FOREIGN KEY (PERSON_ID) REFERENCES PERSONS,
     MARRIAGE_ID NUMBER NOT NULL,
     CONSTRAINT ACT_MARRIAGES_MARRIAGE_FK
          FOREIGN KEY (MARRIAGE_ID) REFERENCES MARRIAGES,
     CONSTRAINT ACT_MARRIAGES_PERSON_UNQ
          UNIQUE (PERSON_ID)
CREATE TABLE OLD_MARRIAGES_RELATIONS (
     PERSON_ID NUMBER NOT NULL,
     CONSTRAINT OLD_MARRIAGES_PERSON_FK
          FOREIGN KEY (PERSON_ID) REFERENCES PERSONS,
     MARRIAGE_ID NUMBER NOT NULL,
     CONSTRAINT OLD_MARRIAGES_MARRIAGE_FK
          FOREIGN KEY (MARRIAGE_ID) REFERENCES DIVORCES
/The two tables to represent marriage_relations (actual and old ones) are there only because with this choice it is possible to specify a unique constraint on actual marriages that avoids the same person to be related in different marriages.

Logical data Model Using ODI

Can I create Logical data Model Using ODI ? If yes how can I do it ?

User,
ODI is not a tool to design. It's a comprehensive integration platform.
However if you would like to model your data, you can use for example Oracle Designer 9i, which is availble one the Oacle website for free.
Oracle 10gR2 Designer is also availble at: http://www.oracle.com/technology/software/products/designer/htdocs/winsoft.html
Good luck.

Issue in creating a custom data model from BP

Hi Team
We have a requirement to create a custom data model by copying data model BP. I have successfully created new data model ZP . I have copied the UI for searching from BP. Issue is when i search a business partner ideally it should not display any entries because i have just created the data model, But it is taking entries from BP and getting displayed. Please let me know how to map data model to search UI. I dont see option USMD_MODEL here

Hi Imran,
actually that is not an issue but a designed feature. I'm afraid that you need to re-think your whole project. The explanations is rather simple:
Data model BP in MDG is a so called Re-Use Area data modell. This means that active data (records that are currently not stored in a change request) are saved in existing SAP ERP data base tables like BUT000 for the business partner master data and LFA1 or KNA1 for Vendor or Customer master data.
If you copy data model BP to ZP you still refer to the same active area. You will always find the same active objects - no matter which data model you are actually using for the user interface. The only difference wil occur for objects being currently processed in a change request. In that case a separation between BP and ZP is possible. But this won't help to solve your issue.
From SAP side I can only recommend not to copy BP but to find a different way of integrating your project needs into BP.
Best regards
Michael

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.

Can't create connection with Data Modeler 2.0.0 570

I have installed SQL Developer Data Modeler on my Windows Vista Home Premium system and am unable to create a connection to import a Data Dictionary. When I select TNS from the connection type dropdown list , I get a message below that states: 'Warning ORACLE_HOME environment variable is not set'.
This is odd, since I use SQL Developer daily on this same system with no issues. I have checked with regedit and the ORACLE_HOME environment variable is indeed set.
Any ideas?

I ran into a similar where Data Modeler was finding the TNSNAMES.ORA file for the older Oracle 8i client (which I have to keep installed because some older legacy software depends on it) rather than the 10g client. My solution was to make use of a suggestion for a simialr problem with SQL Developer and create a DOS "cmd" file in the "+<data modeler install dir>+\datamodeler" directory that sets the ORACLE_HOME environment variable to my 10g client directory and then runs "datamodeler.exe". My file is named "datamodeler.cmd" and contains the following two lines:
SET ORACLE_HOME=C:\oracle\product\10.2.0\client_1
start datamodeler.exe

Best practice - creating functions in data model vs. rtf template

Just a general question. Is there a best practice of creating functions in the data model vs. creating the functions in the data template?
For example, is it more efficient to sum two fields in my SQL query or to create a function in the template that sums the two fields? Just curious if there is any performance benefit of one over the other.
Thanks!

anything you push it to DB(SQL), will be the faster than processing outside.
