Trouble saving Data Modeler design 4.0EA3

Hello,
I'm having trouble saving a Data Modeler design. I can create and import tables into a physical model; however, when i save the model (File > Data Modeler > Save) it doesn't appear to be saved correctly since the resulting .dmd file is 0 bytes. If i close the design and reopen it, none of the tables that i created appear.
I'm using version SQL Developer Version 4.0.0.13.30 on Windows 7.
Thanks,
Pete

i don't see any recent errors in the datamodeler.log file. the only entries for the last 2 days are:

if run sqldeveloper\sqldeveloper\bin\sqldeveloper.exe, the only message in the console is:

no other messages.
I have 3 different builds of sql developer 4.x - they all have this problem. My 3.2 build does not have this problem. So, next, i installed the Data Modeler standalone version (4.0.0.825) and created a physical model with just one table - and i was able to save it! The .dmd had the following content (not 0 byte):
<?xml version = '1.0' encoding = 'UTF-8'?>
<OSDM_Design class="oracle.dbtools.crest.model.design.Design" name="test_dm_only" id="986F3685-3223-BAF6-8D69-6C2C4C52718E" version="3.5">

<designId>986F3685-3223-BAF6-8D69-6C2C4C52718E</designId>
</OSDM_Design>
So, looks like the Data Modeler works, but there's a problem with my installation with the full SQL Developer product. One thing that i noticed is that my full SQL Developer install does not have a full list of logical types. I had to manual create a the ones that i use. In the Data Modeler only install, all of the logical types were available out of the box.

Performance impacts of attributes versus entities in data model design

I'm trying to understand the performance implications of two possible data model designs.
Here's my entity structure:
global > the person > the account > the option
Typically at runtime I instantiate one person, one account, and five option 's.
There are various amounts determined by the person's age that need to be assigned to the correct option.
Here are my two designs:
Design one
attributes on the person entity:
the person's age
the person's option 1 amount
the person's option 2 amount
the person's option 3 amount
the person's option 4 amount
the person's option 5 amount
attributes on the option endity:
the option's amount
supporting rule table:
the option's amount =
the person's option 1 amount if the option is number 1
the person's option 2 amount if the option is number 2
the person's option 3 amount if the option is number 3
the person's option 4 amount if the option is number 4
the person's option 5 amount if the option is number 5
Design two
attributes on the person entity:
the person's age
attributes on the option entity:
the option's amount
the option's option 1 amount
the option's option 2 amount
the option's option 3 amount
the option's option 4 amount
the option's option 5 amount
supporting rule table:
the option's amount =
the option's option 1 amount if the option is number 1
the option's option 2 amount if the option is number 2
the option's option 3 amount if the option is number 3
the option's option 4 amount if the option is number 4
the option's option 5 amount if the option is number 5
Given the two designs, I can see what looks like an advantage for Design one in that at runtime you have less attributes (6 on the one pension member + 1 on each of 5 options =11) than Design two (1 on the one pension member + 6 on each of 5 options = 31), but I'm not sure. An advantage for Design two might be that the algorithm has to do less traversing of the entity structure: the supporting rule table finds everything for the option's amount on the option.
Either way there is a rule table to determine the amounts:
Design one
the person's option 1 amount =
2 if the person's age = 10
5 if the person's age = 11
7 if the person's age = 12, etc.
Design two
the option's option 1 amount =
2 if the person's age = 10
5 if the person's age = 11
7 if the person's age = 12, etc.
Here it looks like the rulebase would have to do more traversing of the entity structure for Design two.
Which design is going to have better performance with a large amount of rules, or would it make a difference at all?

Hi!
In our experience you only need to think about things like this if you were dealing with 100s or 1000s of instances (typically via ODS). As you have a very low number, the differences will be negligible, and you should (usually) go with the solution which is the most similar to the source material or the business user's understanding. I also assume this is an OWD project? Which can be even better, since the inferencing is done incrementally when new data is added to the rulebase, rather than in one "big bang" like ODS.
It looks like design 1 is the simplest to understand and explain. I'm just wondering why you need the option entity at all, since it seems like a to-one relationship? So the person can only have one option 1 amount, one option 2 amount etc, and there are only ever going to be (up to) 5 options...is that assumption correct? If so, you could just keep these as attributes on the person level without the need for instances. If there are other requirements for an option instance then of course, use them, but given the information here, the option entity doesnt seem to be needed. That would be the fastest of all :-)
Either way, as the number of instances is so low, you should have nothing to worry about in terms of performance.
Hope this helps! Write back if you have any more info / questions.
Cheers,
Ben

SAP BW SRM Workflow data model design

Hi All,
I have a requirement from my client to design SAP BW SRM Work flow report, in output user is interested for document flow/chain starting from Shopping cart (SC) - Bid invitation (RFx) - Bid (RFx responses) - Purchase order (PO) - Confirmation. There are standard datasources and DSO's for the same but I want to check experts ideas on data model design. I am thinking to build infosets on top of DSO's but it will impact Query performance as data volume for sure will be more and will increase down the line. In addition I need to consider below exceptions or restrictions as well:
1. Document may/may not start with SC for example one possibility is document start at SC and end at Confirmation or start at RFx and end at PO etc.
2. User is expected to see below various possibilities of document chain in report output:
SC - RFx - RFx responses - PO - Confirmation or
SC - RFx - RFx responses or
SC - PO - Confirmation or
SC - RFx - RFx responses - PO
SC - RFx or
RFx - RFx responses or
RFx or
RFx - RFx responses - PO or
RFx - RFx responses - PO - Confir or
PO - Confiramtion or
PO
your help and ideas on this is greatly appreciated
Thanks and Regards,

Data model design in SAP BI

Hi All,
I have one requirement to design the data model for BI. How to design a dataflow in BI. I know dataflow is different from data model. Could you pls let me know hoe to design it.
Is there any model available ...so that i can refer. if not let me know clearly what is a datamodel and how to design it.
Thanks,
Jack

Problem saving data model when using Oracle DB Pivot feature

I have problem saving a data model - SQL Query that uses the Oracle DB PIVOT feature?
When I hit save, nothing happends.... have also tried "save as" - nothing is saved
No error message is shown.
Is Oracle DB PIVOT not supported by OBIEE?
The SQL that is causing the problem is this one:
SELECT * FROM
SELECT field_name as field,
CASE
WHEN col_1 = 'A' THEN 'Name 1'
WHEN col_1 like 'B_%' THEN 'Name 2'
END
as gastype,
energy
FROM table_1
WHERE code = 'K'
AND trunc(DAYTIME,'YYYY') = trunc(to_date('2012-01-01 00:00:00','YYYY-MM-DD HH24:MI:SS'), 'YYYY')
AND (col_1 in ('A') or col_1 like 'B_%')
PIVOT (sum(energy) for (gastype) in ('Name 1' as Name1, 'Name 2' as Name2))
order by field
We are using OBIEE 11.1.1.6.7 (Win 2008R2) against Oracle DB 11.2.0.3

Just a wild guess .. Have you done dbsetup after installing IAS and said you are going to said databases ?

Error when saving data model

Hi,
I am new to BI Publisher and created a JDBC data source to a oracle database schema. In my data model I created a simple query as:
select code from lm_code;I tried saving by click on the save icon and getting a pop-up error saying:
*Failed to save Data
Error occured when creating xml data.
TypeError
Unable to get value of property 'label': object is null or undefined*
have looked at the Code tab, presuming its referring to to "LABEL" element here, but couldn't see anything wrong. Any help& indeciation appreciated
USING BI Publisher 11.1.1

Try using an alias for the column like this statement:
select code as CODE from lm_code

How to upgrade Data Modeler design to new version when using subversion?

Hi,
I just installed Data Modeler 3.1 product version and I'm using subversion. When I open a design which I have modified with earlier 3.1EA3 version, I get the message " This design is in old format You should use "Save as... from file menu ...
Is there other more smart way to upgrade to new version than "save as" ? I remember having problems in earlier versions with this also. Am I supposed to save the design with different name or...? Or what is the best way?

Hi ,
I have updated the model to 3.1 version with subversion and I have to say that is quite hard for me,
I have "save as" with other name in other folder and after I have dropped from SVN my current folder and copy the new files to new folder in SVN and add the files to SVN,
I hope that I should not do this workaround too many times in future,
maybe if we save the model below a folder with the version number of the tool will help us but I don't like this option,
I guess someone could help us with a simpler solution than mine,

Data Modeler design rules warning

When I apply the design rules to the relationel model Data Modeler warns me about both Primary keys and Foreign keys "with wrong naming standards is not recommended".
However, I have designed the naming rules in the Tools => General Options => Naming Standard => Templates section for example like this: Primary Key: PK_{table abbr}_{column abbr} or like this {table abbr}_{column abbr}_PK and defined table and column abbreviations. Data modeler warns about either form, and since only recommended naming rules exists I do not understand the warning.

The warning is shown if you deviate/rename the constraints from what is set in the templates, so having selected abbr from the variable list you should not be seeing the warning. We extended the variables to include the abbreviation and it looks like these have not been included in the validation. I have logged a bug to track that.

HR BW Data Model - Design & Delta Possibility

Dear All,
In our SAP BW HR Implementation - we have to do a full load everyday for PA, OM, TA, PY streams. and it is very time consuming.
fyi - we are using generic extractors.
Questions -
1. We would like to know if it is possible to swtich to DELTA. If yes, how!
2. Also any idea on the data modelling part - Like best practice for HR Data Modelling- (we are following LSA).
Crux - is to get the data loaded in time frame from 6-8Hrs from 20+Hrs it is taking currently.
Regards,
Vinay

Hi Vinay,
Have u implemented Deltas to generic extractors ? if yes, can you please share your in puts.
As of now we would like to go for delta, but here are the challenges:
1) How to capture deletion records in ECC and update them to BI?
2) if you are extracting multiple times in day then how would you populate the TIMESTAMP in ECC as none of the info types have TIMESTAMP field

MDM Data model design for Main table visa vis lookup table

Hi ,
I would like to know whether the legal entities or Address table which are common for all MDM main tables like Customer ,Vendor,Material,Business Partner etc can also become a main table when their attributes are around 30-40 range.
Is it a sound design approach to make Company table with about 50 attributes and say address table with 20 attributes as Main table and replicate a small company-id table with 2 or 3 attributes to link to the main table(company)? This will ensure replicating that small table(company-id) to all other Main tables(customer,vendor,......) instead of replicating that big company table as lookup for all main tables?
Thanks in advance for any idea or feasibility comments.
-reo

Hi, Deepak
>>> - How can I populate the data in the lookup table at the same time when I am populating the main table ? I have only the XML's that correspond to the main table . I don't have seperate data for the lookup tables .
I don't think you can populate both main table and all fields of lookup tables at the same time, i.e. using same map. You can consider 2 options to upload all information you have:
1) If your XML file contains data you would like to upload to lookup tables, you can upload it to MDM lookup tables with several maps using same XML and choosing different sections of that XML corresponding to different MDM lookup tables.
2) Also you can upload main table simultaneously with lookup table entries (using same map), but in this case new lookup table entries will only contain display field values that you mapped. To do this you should use 'Add' value mapping functionality for fields that you mapped to lookup tables.
>>>- Can I use the standard maps available for import in the business content of material repository in MDM ?
1) In case you have material master repository delivered by SAP and you use XML files which structure corresponds to SAP predelivered XSD schemas then you can use these maps undoubtedly.
2) If your repository is based on SAP predelivered, but you changed it ,you should adjust these maps due to differences in repository structure and XML files structure.
3) If you created your repository from scratch you should consider option of making your own import maps.

Trouble saving date in CMP EJB on OC4J

I have a CMP EJB that I'm trying to update and there is a field that maps to date type in the table.
I get the following error when I try to assign a string literal of the type YYYY-MM-DD:
javax.ejb.EJBException: Error saving state: ORA-01861: literal does not match format string
How do you know what format string the container is using/expecting to pass to the database???
How can you specify that? The EJB itself has the field as a String, not a Date. Should it be a Date?
The OC4J container created it that way to begin with.
I'm using JDeveloper with embedded OC4J and the database is 8i.

Yes, the CMP-field's Java type should be Date. On the database side, the column-type is DATE.

Data model Design-BI.7.0

Hello Experts,
I have a BW 3.5 AS IS system where I have a data flow
6Data sources---> 1 infosource-> UR> ODS> UR-> Cube
Now I need to Map this data flow into an entirely new BI 7.0 System.
I think of two options to map this flow into my new system
1) Map 6 transfromations to an Infosource and 2 transfromation to the UR fro DS0 and Cube (8 transfromations)
2) Map 6 data sources directly to the DSO with out any infosurce in the middle(6 transfromations) and then a transfromation to Cube --- IS this correct method as I see no infosource is needed in BI 7.0
Do I need to create an infosource or not ?
What is the Best method to implement this.(If a start routine exist in AS IS in UR, then What i need to do to in BI 7.0 to implement this START routine as its realed to structure coming from infosurce)
Thanks alot for your suggestions

Hello,
here is some points which can helps your requirements
The InfoSource is not mandatory anymore. However, they can be used eg where you need
InfoObject based information and this is not part of the DataSource.
1.Transformations are dirctly linked from source infoprovider(or data source) to a target infoprovider
2.An infosource is usually not needed
3.New infosource architecture is used (Flat-info object based
eg. A flexible infosource is necessary inorder to use currency or unit conversion from source Datasource-->define infosource as intermediate structure
the infosource as uniform source for several targets
info source is not mandatory in 99% cases
for your scenario you can use the flow as without infosource i.e 6 datasources> 6 tranformations>ODS
start rotine can be used in the transformation as well if you are not having the infosource also
Hope this will helps you
Thanks
Ramesh.

Query about Data Model Design, UPDATED_ON

hi on a *.ppt called ODTUG2007_Advanced_APEX.ppt, that i found on google <www.oracle.com/technology/products/database/application_express/ppt/ODTUG2007_Advanced_APEX.ppt>, i found a something that might be very interesting in using in my APEX app... it said something about some Standard Columns, and "phrases" (created_by, created_on, updated_by, updated_on) that i would like to see and learn how to implement.
So i do appreciate if anyone has got an example, or can explain them to me...
Best regards.
Jaison González

Jaison,
There's another way to do that might work for you:
1. Create the fields updated_by and updated_on in the table;
2. Create in the page the items PX_UPDATED_BY and PX_UPDATED_ON of type "Text field (saves state)";
3. Go to the properties of the item.
PX_UPDATED_BY
Source:
- Source Type: Database column;
- Source Value or expression: updated_by
- Post Calculation Computation: :APP_USER
Default:
- Default value: &APP_USER.
PX_UPDATED_ON
Source:
- Source Type: Database column;
- Source Value or expression: updated_on
Default:
- Default value: sysdate
- Default value type: PL/SQL Expression
When the user submits the changes, the table fields are updated.
