Database-Table parent-child design
Hi all,
Which (forum) does this master-detail table design question belongs to or appropriate to post to?
I have 3 basic entities> servers, databases, and apps
example:
servers=server1,server2,server3,etc
database=PROD1,DEV1,TEST1,etc
apps=GL,FA,AP,AR,INV,HR,etc
In every server there are many database type (dev,prod,test,prod1, prod2,etc)
In every apps there are many database type too (dev,prod,test,prod1, prod2,etc)
So databases are children of both servers and apps?
To which parents does this "children" database legally belong?
Thanks

In every server there are many database type (dev,prod,test,prod1, prod2,etc)It possible, i mean on same server you could have EBS's database like dev,prod and also can have oracle database which is not belong any EBS system like sid ORCL
In every apps there are many database type too (dev,prod,test,prod1, prod2,etc)I belive this is wrong, One EBS has one Database but it doesnt mean that database need extra data from other source which is using ETL etc. So your EBS db always parent and get data from child, and also that main db can update information which is exist on child
You could have one PROD and can clone it as CLON so those 2 instance have actualy same data and same proporties, we cant say those dbs has parent-child relation. But we can say CLON ebs produced by PROD instance

Hierarchy Table - Parent/Child Value Pairs w/o Node Name
Hi,
Has any body worked with below senario to create a Hierarchy table through Import Manager. If so how did you do it? I followed and sucessfull with some senario's by refering the blog "MDM Import Manager: handling multiple formats of source data for hierarchy" by pandey but not with this one. This scenair is actually from help.sap.com

Edited by: SDN POWERED on Jun 7, 2009 8:59 PMHi SDN Powered,
For Hierarchy Table - Parent/Child Value Pairs w/o Node Name just do as follows:
1) In the Source Hierarchy tree, select the Parent and Child field nodes which you want to use to build hierarchy.
2) Right-click on one of the nodes and choose Create Hierarchy Field from the context menu, or choose Source > Create Hierarchy Field from the main menu.
3) MDM opens the Create Hierarchy Field dialog box. This dialog box contains 4 feilds, viz Hierarchy Field Name, Parent Field, Child Field, and Node Name Field. In the Hierarchy Field Name, type the name for the new field.In the Parent Field, Child Field. For Parent/Child Value Pairs w/o Node Name , set the Node Name Field to None.
4) Click OK to close the Create Hierarchy Field dialog box. The MDM Import Manager creates Hierarchy using the values you have provided.
I hope I am able to solve your problem.
Thanks & Regards

Dimension tables - parent child or hierarchical
The data I m dealing with is structured as follow.
A customer has many stores and each store has a POSSystem.
Customer
Stores
POSSystem
So now when I create Dimensions, will I create as:
TableName Cols
DimCustomer CustKey
DimStores StoreKey, CustKey
DimPOS POSKey, StoreKey, CustKey
Are these Hierarchical or Parent Child?
Now when I will create Fact table, will I have:
TableName Cols
Sample1: DimFactPOS CustKey,POSKey,StoreKey, #trans
OR
Sample2: DimFactPOS POSKey, #trans
If I do sample1, then why do I keep "StoreKey, CustKey" in DimPOS?From your question, I can assume that you have beginners knowledge in Data modeling and Data Warehousing.
Let me elaborate it and dilute your confusion.
You have designed
Star Schema; basic intention for having star schema is to have normalized fact tables and de-normalized dimension tables.
Reason you are creating three dimension (i.e. DimCustomer, DimStores and DimPOS) here because you must have many-to-one referential integrity between each level. You can google about Hierarchies,
Levels and Level relationships to get insight information about it.
Keeping normalize data in dimensions and keeping keys in fact table is a business decision. To which level you want to show the aggregated data? You
need to define granuality level based on business needs.
As in star schema, there is 1 fact table related to different dimensions. If I sub divide your assumption, Sample 1 represents
Data Mart and Sample 2 represents Data Warehouse.
I hope it will help you in understanding basic concepts. -
Database Polling: Parent-Child Relation
Hi all,
We are experiencing problem while picking multiple records from child table while polling from the database.
Summary:
Parent table: Temp1 : Columns- Id,Name,Status
Child Table: Temp2 : Columns- Id,Item
Now lets say data present in table are
Temp1 Table :- 1,'abhi','N'
Temp2 Table :- 1,'pen'
1,'pencil'
I have used 1:M Relationship. I have kept a polling on parent table for column status. (Logical Delete)
Problem:
Now what is happening is that, from Child Table (Temp2) only first record got picked up 2 times..and record from Temp1 Table was being picked correctly.....
Can anybody help me how to resolve this issues....its bit urgent.
Thanks in advance.
Thanks,
AbhishekHi sunil,
Thanks for the reply. Relationship defined was correct.
I got the solution for this problem. Actually the primary key on child table was not set correctly. For such scenarios we need to have composite key on child table. when I make that, it started working.
Note that the composite key value has to be unique in the childs table.
Wow!!!
Thanks,
Abhishek...

Trigger & Mutating Tables (Parent-Child relationship, Referencing Constraint related)
Dear Sir,
Wish you a very Happy New Year !!!
I am facing a problem related to Database Trigger.
Sir, I have two tables Cust and Sick.
Cust is having the following fields :
SDF_CUST_BRCD NOT NULL NUMBER(5)
CUST_CUSTID NOT NULL VARCHAR2(6)
UCD_CUST_SEGMENTCODE NOT NULL VARCHAR2(7)
CUST_FIRSTBORROWER NOT NULL VARCHAR2(30)
UCD_CUST_CONSTORGCODE NOT NULL VARCHAR2(7)
VLGC_CUST_VILLAGECODE VARCHAR2(4)
CUST_PAN VARCHAR2(20)
UCD_CUST_STAFFCODE VARCHAR2(7)
CUST_RESIDENTSTATFLAG VARCHAR2(1)
CUST_BKGSINCEDATE DATE
UCD_CUST_SICKUNITCODE VARCHAR2(7)
Cust's Primary Key is the combination of Brcd, CustId
And Sick Table Structure is as under :
PRDT_SICK_REPORTDATE NOT NULL DATE
CUST_SICK_BRCD NOT NULL NUMBER(5)
CUST_SICK_CUSTID NOT NULL VARCHAR2(6)
UCD_SICK_REASONCODE NOT NULL VARCHAR2(7)
SICK_SINCEDATE NOT NULL DATE
SICK_LOSSMAKINGDATE DATE
SICK_ACCMLOSSAMT NUMBER(16,2)
UCD_SICK_VIABILITYCODE NOT NULL VARCHAR2(7)
UCD_BIFR_STATUS_CODE VARCHAR2(7)
SICK_BIFRDATE DATE
SICK_REHABSANCDATE DATE
CUST_SICK_SICKUNITCODE VARCHAR2(7)
Sick's Primary Key is the combination of ReportDate, BrCD, Custid
Sick's (Brcd and Custid) referencing to Cust (BrCd, CustId).
I want to insert/update into the sick table corrponding to Cust
Insertion/Updation.
I have written a trigger on Cust which is working fine provided
that foreign key constraint
is diabled. As soon as constraint is enabled the trigger is
giving error
ORA-04091: table CIS.CUST is mutating, trigger/function may not
see it
Sir, It is also working fine if the record is already exist in
Sick table.
Is is not working in 2 cases :
1. While entering a new record into the Cust with
SICKUNIT_CODE='SW00001'
2. If we are changing the SickUnit_Code in Cust and correponding
record doesn't exist in Sick.
Please write me the solution.
Thanking you
yours sincerely

Database Table Resource - What does it actually do?
Hi,
I want to know what it actually means to grant a database table as a resource to a user in IDM.
For E.g.: When I provision a NT resource to a user using IDM, it means that a Windows NT account is created for that user.
However, when I assign a Database table as a resource for a user of IDM, it does not create a user account for that user.
I am using mySql, and I have assigned a DB table as a resource for a new account. However, I find that such a user is not created in mySql. What does that mean? How then does this user access that database table?
I was under the impression that a user account would be created in mySql having privileges for that table. In effect, a SQL statement like "Grant all privileges on <tablename> to <username> ".
Thanks in advance.If you want to create or edit mysql users, you would use the MYSQL resource adapter, not the Database Table adapter. The database table adapter is designed to manage rows of a table within the database. Neither allow arbitrary SQL to be excuted, but you could make SQL calls via express in your form or workflow.

Parent-Child Join on tables in Database Adapter
Hi,
We are doing a join on two tables(T1 and T2) in Database adapter for an Insert operation. There is no Reference Integrity between these two tables in Database, but join is done through bpel database adapter.
Here is a scenario - when we try to insert a record(parent-child), into these two tables, If there is any data issue in any of the child record, Adapter inserts parent-record, also inserts few child-records it processed before it encountered this data issue and terminates.
Issue here is , We want this to be transactional, it means, If any of the child record fails adapter should rollback the entire insert operation both from parent and child tables and exit with an error. Instead BPEL inserting half records into child table.
Is there any parameter I need to set or am I missing anything? Someone please suggest.
Thanks,
PhaniThere are a few options I guess.
1. Add the referential key constraint.
2. Add custom logic in your BPEL project to compensate for any errors you encounter in your BPEL processes. -
Dynamic hierarchy in parent child hierarchy table??
Do you have any experience to handle the requirement of dynamic hierarchy in universe/webi?
We have some data in parent child hierarchy as below u201CCustomeru201D table.
Customer
Parent Child
Z A
Z B
A AA
B BB
AA AAA
For example, Company Z is the parent company of Company A.
Another table, Amount is the amount value of different Customers.
Amount
ID Amt
AA 10
AAA 1
BB 2
Is there any functionality in Universe designer to build related Classes and objects, So that the web intelligence documents represent the following report with the drilling results?
When we want to see the ID and Amt, the expected result should be:
Z 13
when we drill down Z
the result should be:
A 11
B 2
when we drill down A:
the result should be:
AA 11
notes **
the level of hierarchy is dynamic
Any suggestion is appreciated. Thanks.Hi,
The only way to do it is to create recursive derived table that flatten you parent child hierarchy with a given maximum depth.
Here is a sample I built a long time ago to flatten a parent-child hierarchy on Employees table in Foodmart database (SQL Server).

Hi,
I have requirement like we have to delete a record called IT_PROG from jobs table.the jobs table have child tables employees,job_history, the employees table act as parent for employees,departments tables.How can i delete all related records using single query or single pl/sql block.
Thanks in advance,
ViHi,
include it in your original table design would be the best way, with prime key, foreign key constraints and on delete cascade options.
Other than that utilise trigger logic to coordinate your delete, but the first way is definitely the best, as triggers should be a last resort in databases....

Insert Record with Parent/Child Tables doesn't work with Oracle - unlike AC
Hi,
I just Migrated a MS Access 2010 Database to an Oracle 11g Backend with the SQL Developer Tool.
The Migration went fine, all the Tables and Views are migrated.
I'm working with MS Access as Frontend.
The application has some Datasheets with Subdatasheets with Parent/Child Relationship. (1-n Relationship)
After changing to Oracle, it's not possible, to Insert a new Record in a Subdatasheet I always get the following Error Message:
"The Microsoft Access database engine cannot find a record in the table 'xxxx' with key matching field(s) 'zzzzz'"
It used to work perfect with the MS Access Backend, do I need a trigger which first adds the child Record ?
Or what should I do?
Thank youHi Klaus,
Thanks for your answer. I still haven't solved my problem. The only way would be to use a singel 1:n Relationship, but in fact I need a n:m Relationship.
I tried the same scenario with a new Access Application, same result.
To clearify my problem.
Goal: Parent Form with Parent Records, Linked Child Form with Child Records in a Datasheet View => Insert of a NEW Child Record.
I have 3 Tables (table1 = Parent tabel, table2 = Child Table, table12 = n:m Tabel with PK and two FK)
The Recordsource of the Parent Form is Tabel1
The Recordsource of the Child Form is Table2 joined with Table12.
In my Old Access Project, Access Triggered the Insert and filled Table12 with the NEW PK of Table2.
It seems like Access can't do that anymore....
I'm pretty desperate and I'm sure it is just a litte thing to fix..... -

How to filter parent & child rows from tables while export usingData export
Hi,
I have a requirement of export schema. Assume there is a account details table and account transactions table under schema.They have parent child relation exist. if i filter accounts from account details the corresponding transactions in account transactions table should be filterd.How to achieve this?

Whatever, you've posted in the wrong forum (http://forums.oracle.com/forums/ann.jspa?annID=599)
You should post in a more appropriate forum e.g.

Parent Child tables to be displayed as nested table
I want to design a report on External DB tables that have a parent - child relationship.
The way I want the report is to show the child entries nested within each parent row and I want to have a
"collapse/hide" button on each row when clicked to toggle between collapsing/hiding all the child entries on a parent row.First U have to crate Extended View Object to your actual View obj.
Now take Page with Panel Splitter ,on First facet drag View obj as table and on second Facet Drag Extended View Obj as table.On page loading U have delete all rows from Extended View object.And then u have write bean code on button click to get current select rows from above view objct,and for Filter rows from Second View obj according to selection of rows from first view obj... -
Parent child tables - how to maintain RI
Here is my scenario:
In our model, we have parent child relationship between tables.
We are not sure how the parent tables are populated. If incremental update, it should be fine (assuming if needed rows will be inserted in the child table manually). If the tables are truncated and data is inserted again – that might be a problem since there exist relationship with child tables. What are the various options for handling such cases?
Option1: cascade delete
Option 2: ...?I'm not sure I understand the goal here...
- Are you trying to design a data model? If so, wouldn't the business and data requirements tell you whether you need to truncate and reload the parent table or whether you can do an incremental load? It wouldn't seem to make sense to design a data model with no understanding of how the model is going to be used.
- Are you trying to design a load process that works with an existing data model? If so, are you trying to design an incremental load? Or a load that involves a truncate and reload? Does the existing data model have foreign key constraints?
Specifying the Oracle version and a bit of information about the application (i.e. is this an OLTP application, a data warehouse, something else) would probably also be helpful.

Loading to Parent -Child Tables simultaneously
I have a requirement to populate parent-child tables in a single interface simultaneoulsy. I couldnt find anyway to add multiple targets and am wondering why this key feature is absent in ODI. The same thing is easily achievable in BPEL.
Could some one please advice a work around for this.
Your help is much appreaciatedODI 11g does come with a new IKM 'IKM Oracle Multi Table Insert'. This does allow multi table inserts, but will require more than one interface.
Oracle Multi-Table Inserts
A new Integration KM for Oracle allows populating several target tables from a single source, reading the data only once. It uses the INSERT ALL statement.
COMPONENT NAME: IKM Oracle Multi Table Insert
COMPONENT VERSION: 11.1.2.4
AUTHOR: Oracle
COMPATIBILITY: ODI 11.1.1.3 and above
DESCRIPTION:
- Integrates data from one source into one to many Oracle target tables in append mode, using a multi-table insert statement (MTI).
REQUIREMENTS:
- Oracle Database 9iR1 or above
- See BASIC CONFIGURATION section
BASIC CONFIGURATION
- This IKM must be used in integration interfaces that are sequenced in a Package:
- The first interface of the Package must have a temporary target and the KM option DEFINE_QUERY set to YES.
This first interface defines the structure of the SELECT clause of the multi-table insert statement (that is the source flow).
- Subsequent integration interfaces must source from this temporary datastore and have the KM option IS_TARGET_TABLE set to YES.
- The last interface of the Package must have the KM option EXECUTE set to YES in order to run the multi-table insert statement.
- Do not set "Use Temporary Interface as Derived Table(Sub-Select)" set to true on any of the interfaces.
- If large amounts of data are appended, consider to set the KM option OPTIMIZER_HINT to /*+ APPEND */.
OPTIONS (Refer to the Option descriptions for more information on each option)
- DEFINE_QUERY: Set to Yes if this interface describes the source query (SELECT clause of the statement). This interface must have a temporary target.
- IS_TARGET_TABLE: Set to Yes this interface using the source query to load one of the target tables. This interface must source from an interface with a temporary target using this IKM and having the KM option DEFINE_QUERY set to YES.
- EXECUTE: Set to Yes for the last interface in the Package. This interface will run the multi-table insert statement.
- COMMIT: Commit transaction. This applies only to the last interface in the Package.
- TRUNCATE: Set to Yes to truncate this interface target table.
- CREATE_TARG_TABLE: Create target table? May only be used on target interfaces, but not on source interfaces (defining the source data).
- OPTIMIZER_HINT: Hint for the multi-table insert statement.
RESTRICTIONS:
- This KM can only be used in integration interfaces that are part of a Package.
- All source and target datastores need to reside on same data server.
- Journalized source data is not supported.
- Temporary indexes are not supported.
- Flow/static control is not supported.
- The TRUNCATE option cannot work, if the target table is referenced by another table (foreign key).
