How to resolve a many to many relationship in Universe

I have 2 tables
RBU table that contains
Area
Region
Country
Sample Values
Area                       Region     Country
OMD Perimeter     M6     Netherlands
OMD Perimeter     G10     Netherlands
OMD Perimeter     M5     Netherlands
Media Spend Table
Country
Spend
Country          Spend
Neitherlands    50
One region can be contained in more than one Area and Country in turn can be more than one Region
Issue::
When A country is present in more than one Region the Spend is multiplied by the no of regions its present. Where by creating an issues.
Example
If the user choose OMD Perimeter as the Area Spend for Neitherlands is displayed as 150
Is there any way to resolve this issue
Is there a way to hand this issue in the universe.

Hi Divya,
One region can be contained in more than one Area and Country in turn can be more than one Region
(1) Area -> (M) Region -> (M) Country
This a Fan Trap.
You can solve it in the universe desinger:
1. If the measures are having aggregate function then check the following option "Multiple SQL Statements for Each Measure"
    should be checked in the parameters.
2. You can create aliases and context to resolve it.
    a. create an alias for the table which is producing multiplied spend.
    b. create a join between the original and the alias table.
    c. define the contexts.

How to resolve many fact tables and Dimensions tables

Hi,
The scenario is we have many facts and dimension tables. Based on some conditions one measure from one fact will be divided by another fact measure. I have encoutered with many errors like " Unable to navigate .... " ? How to resolve these errors and reduce many to few ? ( I assume creating logical tables, but is there any other alternatives ? )
thanks
Suresh

Suresh,
I assume that you know how to create a single logical fact from n-physical facts, ie only if the fact tables are related. Then join all the conformed dimensions to this single Logical table using a join in the Business Model layer. Remember to set the mappings in the LTS. All if you have any hierarchies please set the aggregation level for those.

How to create ViewModel in an MVVM application using entity framework where database has many-to-many relationship?

I have started developing a small application in WPF. Since I am completely new to it, to start with I took a microsoft's sample available at
Microsoft Sample Application and following the pattern of the sampke I have been so far successful in creating four different views for their corresponding
master tables. Unfortunately, I have got stuck up as the sample does not contain pattern for creating ViewModel when there is a many-to-many relationship in the database. In my application, I have the following data structure:
1. Table Advocate(advId, Name)
2. Table Party (partyId, Name)
3 Table Case (caseId, CaseNo)
4. Link Table Petitioner (CaseId, PartyId)
5. Link Table Respondent (CaseId, PartyId)
6. Link Table EngagedAdvocate(CaseId, advId)
7. Link Table EngagedSrAdvocate(CaseId, advId)
In the scenario above, I am a bit confused about how to go forward creating the required ViewModel which would render me to have multiple instances of Petitioners, Respondents, Advocates and SrAdvocates.
Please explain details in step by step manner considering that whatever work I have completed so far is a replica of Microsoft's sample referred above. I would also like to mention that I have developed my application
using VB.net. So please provide solution in vb.net.
After getting many-to-many relationship introduced into my application, it would achieve one level above the sample application and I would like to share with the community so that it could be helpful to many aspiring developers seeking help with MVVM.

Hi ArunKhatri,
I would suggest you referring to Magnus's article, it provides an example of how you could display and let the user edit many-to-many relational data from the Entity Framework in a dynamic and data-bound DataGrid control in WPF:
http://social.technet.microsoft.com/wiki/contents/articles/20719.wpf-displaying-and-editing-many-to-many-relational-data-in-a-datagrid.aspx

Error saying "this ID has been authorised too many times" , how to resolve ASAP?

Error saying "this ID has been authorised too many times" , how to resolve ASAP?

Adobe Live Chat: http://www.adobe.com/support/chat/ivrchat.html
They can reset your authorizations, and then you must reauthorize any devices you still need.
(Unfortunately, Adobe haven’t got round to an admin website for viewing and editing authorizations.)
Some of the representatives haven't been properly trained and don't know what to do (and claim there is nothing they can do);
in that case the only way seems to be to give up that chat and try another session hoping for a properly trained representative.
If your problem is with another device using Overdrive, Bluefire, Aldiko or similar third party app, it is recommended not to mention that app when on the chat, just mention that you have run out of authorizations (E_ACT_TOO_MANY_ACTIVATIONS) . Thanks to AJP_Bear for that tip.

How to design many to many relationship in the fact and dimension

There is a problem in my project what is the subject.And i wanna know how to implement in owb.I use the warehouse builder 10. Thanks.

You may design and load whatever db model you want to.
But If you set a unique key, you may find some integrity issues. I wouldn't do a many to many relationship between facts and dimensions. This could cause you lots of headaches when users start to submit queries using this tables. You'll probably face performance issues.

How can I establish many to many unidirectional relationship?

Hi, EJB Fans!
I am an ejb fan too.
This time I am learn ejb2.0 and find very funny in cmr. I think it is a good idea and can do manythings we cann't do or difficult with ejb1.1.
But in many to many relationship, I don't know how to give my tables to entity A and entity B. How can I define tables to make A contains related Bs' information? And so do B. But i think make this table is difficult, because we don't know exactly how many should contains? And this is an examples:
Difine entity A as User, and B as roles such as Administration, user, power user, as we often used in network. A user can have many roles, and roles can allocated to many roles.
Another examples is entity A as person, and B as Department. B container A, and A can join many department as he or she can.
B can find A(s) with which clues?? Methods like this java.util.Collection getAs()
, this collection how can ejb container caculate it out?
It is very myth, even wonderful!
I love java and more like ejbs.

No body reply.
My question is silly or my english is very bad.
Sorry I am chinese-speaking programmer.

QUESTION: HOW TO WRITE QUERY WITH MANY TO MANY RELATIONSHIPS

Could someone help me out here?
I was sitting here looking at some tables ie table_name and synonyms and wondering.
If a table can belong to many synonyms and a synonym can belong to many tables how would one write a query where I would like to know which tables belong to each synonym or on the other hand which synonym belongs to what tables?
Would I try to develop an outside join for this, a corrolated query or a query with a subquery or would there be another format that would work better?
What would be the best method of attack on this?
Thanks for your thoughts on this.
al

Actually, the relationship is not many to many. A table can have many synonyms, but a synonym within a namespace (i.e. a PUBLIC synonym, or a private synonym created by a user) can only point to one table. The xxx_synonmys tables already contain the information about the table_name and table_owner.

How Can realize a one-to-many relationship via RIA service in lightswitch

I have to query a large data and the normal query in lightswitch is so slow that I decided to use RIA service to improve the query.However I am not very good at RIA service. I follow
this tutorial and set up a very simple RIA service. In my project, I have a one-to-many relationship but I don't know how to
realize it . here is the Relationship:
public class CombinedStadium
private EcoStatus _ecoStatus;

public string Name { get; set; }
public string Category { get; set; }
public string Owner { get; set; }

public virtual EcoStatus EcoStatus
get { return this._ecoStatus; }
set
this._ecoStatus = value;
if (value == null)
this.Id = value.Id;
I am not sure whether it is right or not. But I want "one CombinedStadium Entity may contains
more than one(many)EcoStatus Entities.
I tried the code above and update my datasource, I got the error "the entity
LightSwitchApplication.Implementation.EcoStatus's property doesn't supported by the type of StadiumEcoReference".

How to model a Many-to-Many relationship in java?

Folks,
I'm having trouble understanding how to properly model a many to many relationship in OO/Java.
The full scenario is in this thread... http://forum.java.sun.com/thread.jspa?threadID=5288115&start=0&tstart=0 it's a college/uni assignment to build a short-course management application. I'm doing the assignment for my own edification.
The scenario (as I see it) is:
* A college offers many Subject's in each of 4 semesters per year.
* A SubjectOffering is identified by the combination of String subjectName, int year, and int semester [1..4]
... each SubjectOffering has a teacher, a cost, a price, etc, etc.
... it models "a running of a named subject"
... for example: "Geography 101 in the first semester of 2007 with Mrs Mappit"
* A Student is identified by String name.
* A Student can enroll in many SubjectOffering's [per semester].
* A Subject has many pupils [per semester].
In my current design:
1. Each Student has a List<Subject> enrollments... of all the subjects they where/are/willbe enrolled in; and
2. Each Subject has a List<Student> pupils... who are enrolled in that subject-offering.
I think I've got an inherent catch 22 here...
1. The student must exist in order to be enrolled in a course;
2. but the course must first exist in for the student to enroll in it.
So which comes first the chicken or the egg? And how?
Coming from a database background, I'm thinking that I really need an enrollments table... that is a List<Enrollment> where an Enrollment object just correlates a Student to a SubjectOffering... modeling: "John Doe did Geography 101 in the first semester of 2007"... that way both the Student and the SubjectOffering can exist independantly of there enrollments/pupils.
But I've got a nagging feeling that there's something basic that I'm just not getting, because I've spent too long in a static C/DB world.
Please can anyone put me straight on the "proper OO way" to do this?
Thanking you, Keith

an Enrollment object just correlates a Student to a SubjectOffering...Sounds like a good plan to me.
Example (Groovy):
class Student {
    String name
    String toString() { name }
class SubjectOffering {
    String name
    String toString() { name }
class Enrollment {
    Student student
    SubjectOffering subject
    String toString() { "$student :: $subject" }
registry = [
    new Enrollment(student:new Student(name:'yawmark'), subject:new SubjectOffering(name:'Biology 101'))
   ,new Enrollment(student:new Student(name:'corlettk'), subject:new SubjectOffering(name:'Chemistry 302'))
   ,new Enrollment(student:new Student(name:'corlettk'), subject:new SubjectOffering(name:'History 204'))
keithSchedule = registry.findAll { it?.student?.name == 'corlettk' }
keithSchedule.each { println it }Output:
corlettk :: Chemistry 302
corlettk :: History 204~

How to create a many to many relationship in forms 10g

hello frnds,
I want to create many to many relationship, can any one help me plz?
Regards
Divya Alok

Hi ,
In this situation create two separate blocks one is master and the other one is detail block.
Then make detail block as database data block with the proper table name.Pass the value that your enter in the master block to the detail block as the search criteria to fetch the data from the table and to show the data related to the master value .If you have multiple master values then create data base data block sql query in such way that it must use all the master inputs as the search criteria.
EX. Some time user wants to see the details of the employee after entering the emp id as the search criteria,that time you have to pass emp id as the search criteria to detail data base data block.Even you can pass emp id and emp name as the search criteria to the detail database data block.
Thanks,
Pavan.

How to create query for tables with many to many relationship

in my sql i'm unable to update the table using select clause...is there any way to update a table which is in many to many relationship.
Ex:1st table student(student_id int primary key auto_increment, student_name varchar(30));
2nd table contact (contact_id int primary key auto_increment, c_email varchar(40));
3rd table student_contact(student_id int references student, contact_id int references contact);
i would like to auto insert the both two columns in the student_contact while the student and the contact table being updated automatically.

This is a JSP/JSTL forum, not a SQL forum. If you're using MySQL, better use their own forums at dev.mysql.com.
I'll give some hints anyway: learn about SQL JOIN. In general there is good SQL documentation available at the website of the RDBMS manfacturer. Go check it out. There is also a nice SQL tutorial at w3schools.com. Good luck.

How to approach this scenario (Many to Many). A bit confused

Hi all,
I have a scenario where I am confused and am looking for some guidance. Let me explain the scenario I have.
I have an Item Table (Which will be used to create Item Dimension) :
ItemID
ItemName
Item1
ItemName1
Item2
ItemName2
Item3
ItemName3
Item4
ItemName4
I have a Promo Table (Which will be used to create Promo Dimension) :
PromoID
PromoName
1
Promo1
2
Promo2
3
Promo3
4
Promo4
I have a Promo Lines table (This is lines for promotion but here is the confusion):
PromoID
LineNum
ItemID
Activity
1
1
Item1
Activity2
1
2
Item2
Activity1
1
3
Item3
Activity3
2
1
Item2
Activity2
3
1
Item3
Activity1
3
2
Item1
Activity3
4
1
Item2
Activity2
4
2
Item1
Activity1
I have a Transaction table "Sales Order Trans Table". This will be used to create "SalesOrderLine" Measure group (Fact) :
SalesOrderNumber
SalesAmount
ItemId
SO1
100
Item1
SO1
234
Item2
SO2
345
Item3
SO2
456
Item1
SO2
567
Item2
SO3
234
Item2
SO3
345
Item1
SO3
343
Item3
SO4
234
Item2
SO4
765
Item1
SO5
567
Item3
SO5
345
Item2
SO5
234
Item1
Now in my cube I need these :
Item Dimension :
ItemID --> ItemID column of Item Table
ItemName --> ItemName column of Item Table
SalesOrderLines Measure Group
Sales Amount --> Sum on SalesAmount column of Sales Order Trans table
Sales Lines Count --> Count of rows of Sales Order Trans Table
Promo Dimension:
PromoID --> PromoID of Promo Table
PromoName --> PromoName of Promo table
Activity --> Activity of Promo Lines Table
Solution I have thought
The Item dimension is straight forward and relation with Measure group is a regular on ItemId --> ItemId. So no issues here
The Promo dimension can be made easily from Promo table with promo Id as Key column. The relationship with fact is confusing me.
For the Promo Dimension, Since it is many to many relationship between Promo and Item , I initially thought of using the PromoLines Table as a Fact less fact Measure group and using that as intermediary measure group in a Many-to-Many Dimensional usage between
the Promo dimension and SalesOrderLines Measure group.
The problem is the Activity attribute that is required on Promo dimension. if I use the PromotionLines in the dimension, I will get the activity, but what will I keep as key attribute(As One attribute is related to one or many lines).
I am very confused with this. Any thoughts on how to resolve this or any suggestion will be very helpful.
Thanks,
Girija Shankar
Please mark responses as answered if it helped you.. This helps others... - Girija Shankar Beuria

You are on the right track. Create the SalesOrderLine measure group. Create the Item dimension. This will be your intermediate dimension. Create a measure group off PromotionLines with a hidden count measure. This is your intermediate measure group. Create
a dimension off the Activity column (that's the key) and relate that dimension with a regular relationship to the PromotionLines measure group. This will be the first many-to-many dimension in SalesOrderLine. Create a Promo dimension with a regular relationship
to the PromotionLines measure group and a many-to-many relationship to SalesOrderLine. This is the second many-to-many. Both m2m dimensions resolve through the same intermediate measure group.

EJB and many-to-many relationship

I write two CMP Beans userBean and roleBean with many-to-many relationship
userBean:
cmp fields: id,name
cmr fields: userRoles
roleBean:
cmp fields: id,rolename
cmr fields: usersinroleIn database I have 3 tables:
USER( ID NUMBER PK,NAME CHAR);
ROLE( ID NUMBER PK,ROLENAME char);
USER_ROLE( (USERID FK(USER.ID), ROLEID FK(ROLE.ID)) PK);in sun-cmp-mappings.xml I add cmp fields mapping,
in userBean and roleBean I add secondary table USER_ROLE
then I add CMR mappings to userBEan nd roleBean
ufter deploying of EJB.jar
in client i wrote:
userBeanLocalHome lh=lookupUser();
lh.create(new java.math.BigDecimal(5),'username');when i run client exception occurs in server log I see:
TransactionRollbackException because Container try to insert into USER_ROLE
values(5(userid),null(roleid)) but user have no roles
in that situation how can I create user without any roles?
thanx!

FaraPooyan, I think about this but it is not good idea because it makes 1-n:1-m relationship.
but I whant 0-n:0-m relationship
I resolve this problem by removing secondary table from sun-cmp-entitymappings.xml
So it works good, but now i dont understand: when i need secondary table mapping if they are not needed for many-to-many relationships

Siebel BI Publisher Report having many-to-many relationship

I have query on creating BI publisher reports having many to many relations. The report requirements has fields from entities Customer, Claims and Payments. For explanation let say fields are customer name, claim ref, payment amount, pay id. claims and Payments entity has many to many relationship. Now my report shows as below. Actual Total Amount Paid to customer is 11,500. However my report total is shown as 13,000. How to resolve this ?
Customer Name Claim Ref Payment Amt Pay Id
Mr XYZ 1001 10,000 1-101
Mr XYZ 1001 1500 1-102
Mr XYZ 1002 1500 1-102
I was thinking about a solution of having two columns side by side within a page. Column left will the show the data Customer to Claims and Column right will show the data Customer to Payments. But not sure how to achieve the rows wise alignment for the new customer records between two columns. If row wise alignment achieved then hope workaround might be accepted by client. Any help in this is greatly appreciated

Thanks for the reply. The many to many relationship between Claims and Payments are achieved through intersection table in siebel. When Customer has multiple claims, single payment issued for both claims. Also single claim can multiple payments such (part compensation, interests, final compensation etc)
