Generating n:m relationships

Hi all,
i have two tables linked via an intersection table, a typical n:m thing. I'd like to generate a form displaying this relationship, like there's the data of the one table in the first block, and all records of the second table - that match the current record in the first block - in the second block. It works as I get all corresponding records of the intersection table, but the fields of the data table, which is defined as lookup to the intersection table, remain empty.
Any idea of what the clue may be?
Any help appreciated.
Thanks
Phil

Dynamically generating workflow and relationship images to the Web

Is there a good toolkit (open source maybe) out there that will allow me to dynamically draw images containing a workflow or show relationships? I only see packages that are geared for charts, I want to dynamically draw the dependency between 2 or more objects on the fly. To be able to do that I need to be able to draw rectangles (2 or 3d), lines with ends (as in Visio or something) and draw text in the box representing the entity name. I don't want to have to code all this myself using BufferedImage etc. Looking for a nice little toolkit.
Thanks

We really need to see what you're seeing.
Can you post links to before and after?

Generating Entity - RelationShip in Oracle SQL Developer.

Is it possible to generate an Entity - RelationShip diagram from Oracle SQL Developer?
Thanks in advance,

If you're willing to pay the 3000 quid per seat (+ annual support costs), take a look at [Oracle SQL Developer Data Modeler|http://www.oracle.com/technology/products/database/datamodeler/index.html].

O/R mapping tool generates bad descriptors for CMP2.0

The O/R tool has many problems with EJB-CMP 2.0.
It generates bad ejb-jar.xml (misses the <cmr-field-type> tag, has the same relationship field included in both the <entity> tag and the <relationships> tag).
The worst part is that is generates bad TopLink descriptors!
I have numerous indirect 1-1 bean-pojo (plain old java object). When I have the 'tool' generate the ejb-jar.xml and deployment xml it generates all these relationships incorrectly.
The O/R 'tool' forces you to use transparent indirection for CMP 2.0 relationships; transparent indirection does not allow you to specify 'use method accessing'. Fine. But when I go to deploy the compiled jar, I get ALL sorts of errors complaining that:
EXCEPTION [TOPLINK-1] (TopLink (WLS CMP) - 9.0.3 (Build 423)): oracle.toplink.exceptions.DescriptorException
EXCEPTION DESCRIPTION: The attribute [addressToDesc] is not declared as type ValueHolderInterface, but its mapping uses indirection.
MAPPING: oracle.toplink.mappings.OneToOneMapping[addressToDesc]
DESCRIPTOR: Descriptor(...
ARGH!! What the heck do I need to do to get this 'tool' to work? It won't LET me use valueholder in EJB-CMP2.0, but then it complains when when I don't!?!?!
Frustrated,
Andrew

(from toplink support)
Andrew,
Hi there. I've performed some research regarding
your question, and it appears that having an
"automatic" 1:1 indirect relationship between an EJB
2.0 Entity Bean and a dependent Java object is not
currently supported by TopLink. Examining the
documentation, this non-support unfortunately isn't
documented. I have entered a feature request on your
behalf so that we might be able to support it in a
future major version of TopLink.
However, there are a couple of alternatives which
you can use:
1) We do support non-indirect 1:1 relationships
between an EJB 2.0 Entity Bean and a dependent Java
object. You could disable indirection, and maybe
make the relationship a batch read relationship so
that your performance will not be degraded.
2) You can write a concrete getter and setter, and
provide an instance variable on the entity bean for
your dependent object of type ValueHolderInterface.
Provide the private getters and setters for set and
get -Holder. Map this normally using TopLink, and
make sure Indirection is specified in the Mapping
Workbench.
IMPORTANT: TopLink will handle the normal
persistence management for this relationship,
however you will need to handle the merging back of
this object yourself (you had to do this in EJB 1.1
in TopLink as well). Luckily there are good docs on
this, and it's covered in detail - look at the
TopLink for WebLogic documentation : Runtime
Considerations > Managing dependent objects.
Personally, I would implement solution 1) with batch
reading on the attribute, because the dependent
object shouldn't be that "big" (otherwise it would
be an entity bean). This is an easier solution,
however you should investigate 2) fully yourself.

Custom BDOC issue for xif interface

Hi CRM gurus.
I am using XIF interface for sending BP and REL details to external system.The creation of contact person doesnu2019t have standard address fields (postcode, city etc). We are enhancing webclient by adding standard address context node and save the data. Now problem is with Bdoc and Idocs. What is the procedure to add this address for BUPA_REL object and where I have to modify the code which generates bdoc for relationship along with address. I found BURS_EI_ADDRESS is the address structure used for BUPA_MAIN. Please help me out with possible answers. Looking forward for answers.

Loading xml into relational tables.

I was wondering if anyone knows of a product/libraries which does the following:
-Read data from a relational Database (multiple tables) and generate XML files based upon an XML Schema or DTD file?
-Read XML files and load data into a relational Database.
-Graphical Interface for performing the maps (perhaps based upon .xslt). ie.... Mapping of the XML Schema to Multiple Database Tables, Performing Joins etc...
-Ability to connect to any type of Relational database (not just Oracle). Which rules out XML DB.

This product does look to be ok, however it is missing a couple features that I would like the product to have.
I would like this product to be able to insert/update data across multiple tables. Being able to do such things as generate foreign key relationships.
It doesn't seem as though the XML being generated can be customized very easily. Some XML formats I deal with are very complex (such as X12/EDI).
I would really like a graphical mapper.
Here is a note from the doc:
Storing XML Data Across Tables
Currently the XML SQL Utility (XSU) can only store data in a single table. It maps a canonical representation of an XML document into any table or view. But there is a way to store XML with XSU across tables. You can do this using XSLT to transform any document into multiple documents and insert them separately. Another way is to define views over multiple tables (using object views if needed) and then do the insertions into the view. If the view is inherently non-updatable (because of complex joins), then you can use INSTEAD OF triggers over the views to do the inserts.
This product looks really good, I was hoping that Oracle had something comparable:

i was just testing this form by querying records and repeatedly changing values inside form and saving,
just to confirm the validation are being performed as expected.
how form is behaving, on some records, it is allowing me changing values over-n-over without the error(above),
but on some records it allows editing, but if i repeat changing values, the error is flashed.

Please ADVISE: Implementation of ARCs at Table Level

Dear Colleague,
While modeling with Designer (DS9i, Release2), I have made use of Arcs, i.e. when only ONE of two or more relationships are applicable at a time, but two or more of the relationships are possible.
I have the situation in which an ARC contains two relationships that are also part of the primary key.
My question is: How will designer implement this at the table level when I generate the table defintions from the entity definitions?
I assume:
1. that one column is generated for each relationship.
2. that a check constraint is generated e.g.
(col_1 is NULL and col_2 is NOT NULL) OR
(col_1 is NOT NULL and col_2 is NULL)
Since one of the two columns must be NULL, these columns cannot be part of the Primary key. Does Designer consequently, generate no Primary key constraint, but only a candidate key constraint?
Please advise.
Best regards,
Randy

Hi Randy,
I suggest you make changes in the table design after transformation. You can then arrange your own design solution to the problem (either single key or multi-key with check constraints). Remember the database design transformer is not intended to provide a directly usable design, just a 'first-cut'.

Data Modeler foreign key names

Hi,
I've been using Data modeller for a while now and it works beautifully, anyhow there is an issue I would appreciate if anybody can help me in.
For foreign keys, if the master table primary key is names ID, the foriegn key will be ID also, and if already there is an ID column column in the detail table, it will be ID1, ID2 ....
Can I change the naming method to be like the oracle designer, or any convention I would like ??
Thanks
AK

I'm using the Logical Model V 1.5.1Paul,
it's pre-production release. Data Modeler is free now and you can download current published release - it.s version 2.0.0.584.
There is "Attributes" page in relationship dialog (version 2.0) and you can see attributes generated by that relationship.
For foreign keys in relational model - there is "Associated columns" page, you also can see referred key there.
Naming templates for FK columns and attributes can be defined in version 2.0.0.584.

i have 2 cmp entity ejb with one-many relationship between them. I wrote QL query using foriegn key. when i generate EJB-RDB mapping the error appears in TASK saying " myTable o does not have a field myforeignkey". when i click on tast it opens ejb dep...descriptor. i check descriptor and foreign key is there.
where should i look? when i run validation before mapping generation it doesn't produce any error.

i am new to J2ee and i let websphere to generate all description code. I spend 4 hours looking for this error and i just can'f fix it. it looks fine to me. can you have a look? i know the code is big. if you get extra time then help me. i cut it down. there is two entity beans each with one attribute. order id has second attribute as foreign key -generatorhome_id.
the full error is like this:

Multiple referenced relationships over the same intermediate dimension - generated processing query

Hi, I know the title is a bit confusing so let me try to explain it:
I have added 3 new dimensions do the AdventureWorks cube - RefA, RefB and RefC:
They are all related to the DimReseller table, and finally, to the FactResellerSales table. In the dimension usage chart, you can see that there are 4 referenced relationships using the Reseller dimension as the intermediate dimension. The Geography
was the existing one, and the other 3 were added.
Now, if I process a partition from the Reseller Sales measure group, the Profiler catches this generated query on the server:
SELECT [dbo_FactResellerSales].[dbo_FactResellerSalesSalesAmount0_0] AS [dbo_FactResellerSalesSalesAmount0_0]

As you can see in the comments, the generated query contains 1 join on the referenced table
per referenced relationship. This can slow down the processing if both the Fact table and the Referenced Dimension table are big (and they usually are, otherwise the design would be different). The thing is, all 4 tables are filtered in the
WHERE clause on the same condition, which makes perfect sense. This leads to the conclusion that all 4 columns could have been read from a single join.
I was quite surprised by this kind of query generation and I can't seem to find a reason why this would be so, or how it could be avoided. Naturally, the RefAKey, RefBKey, RefCKey columns could be added to the Fact table, eliminating the need for referenced
relationships, but this would add 3*4 bytes per row to the Fact table. The Fact table in my real example contains around 3 billion rows, so adding extra bytes is painful. (Yes, it's partitioned but still ... )
The referenced relationships could also be "dematerialized" by removing the famous Materialize check in the relationship settings. Then again, this would issue a join to the referenced tables at query time, slowing down the query.
Has anyone been profiling processing queries like this one and stopped to think about it?

I don't believe it's on the Essbase side, as it uses a fairly standard API to allow string input to such things, and it's limitation is well beyond 512 chars even for a direct formula input. I instead suspect that a carriage return/line feed is being inserted by the ODBC driver as part of it's output formatting, and this is causing the API to consider the input record "completed." I could be wrong, of course, but if you examine the Memo field closely, you may find the formatting to have migrated to the Access database, and even if not, you are still using ODBC to access it on the output side, so we're back to the same issue. Perhaps it really is an issue related to the ODBC drivers in Essbase, but it's not unique to dim build, to formulas, or Essbase for that matter. Allowing a single field to output more than 512 chars in a single field is where I believe you will find the real issue. Again, we need an ODBC expert to weigh in on this. <img src="i/expressions/face-icon-small-smile.gif" border="0">
