where can I find the table relationship for Oracle HCM tables? Does it even exist? I can't find anything related to it.
Thanks.
Please refer the below link. Don't forget to change 22b to 22c and to 22d then 23a for regular quarterly updates.
https://docs.oracle.com/en/cloud/saas/human-resources/22b/oedmh/index.html
This guide contains the information about tables within Oracle HCM Cloud and their columns, primary keys, and indexes. The guide also includes the information about views within Oracle HCM Cloud along with the columns and queries associated with each view.

While configuring the JDBC driver to extract metadata from Snowflake like tables, columns, views - what attributes I should make use of to extract table descriptions, column descriptions, tags associated to tables etc.
Also, is there a place wherein I can see the exhaustive list of metadata attributes.
When I configured the snowflake JDBC driver in Collibra data catalog, it fetches only table names but not descriptions, column names but not descriptions.
To get an exhaustive list, use the INFORMATION_SCHEMA. Each database has an INFORMATION_SCHEMA schema within it with a bunch of useful information. You can also use the SNOWFLAKE database which holds similar information across the account.
These two options will probably give you more information than you can get from the JDBC api.
I have two separate database in two separate servers. Both these database have same table . I just wanted to compare similar tables wrt to the data contained.
Also to access one database from other database do I need to create a DBLink

How to know index usage of particular module in Openedge 10.2 which uses Oracle db schema?
I have used XREF but .xrf does not give any index details for my module, so I have run below simple query and then checked in .xrf but no index detail available.
FOR EACH tablename NO-LOCK USE-INDEX indexname:
DISPLAY tablename.field.
END.
Please help me how to get index detail for Progress db using oracle schema.
First I assume you are using Oracle DataServer from Progress.
If that is the case, bear in mind that all USE-INDEX will be translated basically into ORDER BY in the resulting query, so mostly being used to order not to access the data.
If you want a know how your information is accessed you'll need to enable qt_debug when connecting to the schema holder, that will allow you to print many information about how your progress code is translated to SQL to access the Oracle DB. You'll need to analyze those SQL (SQL EXPLAIN as an example) to see the performance of your queries and how they are accessing the DB.
Can Oracle Materialized views be used to join multiple related tables having foreign keys to create a larger denormalized big table which is refreshed instantaneously?
On some investigations, it says that joins are not allowed while using fast refresh.
Is it my assumption which is wrong that i can do this sort of thing with Oracle Materalized views?
Assuming all the tables are local (i.e. you are not trying to replicate the data from a remote database and do the joins all in one step), the restrictions you need to be aware of are listed in the Data Warehousing Guide, not the replication manual. The specific set of restrictions depends on the Oracle version but you should be able to create a fast-refreshable denormalized view of your data.
I am new to Oracle. Since we have rewritten an earlier application , we have to migrate the data from the earlier database in Oracle 9i to a new database , also in 9i, with totally different structures. The column names and types would be totally different. We need to map the tables and columns , try to export as much data as possible, eliminate duplicates, and fill empty values with defaults.
Are there any tools which can help in mapping the elements of the 2 databases , with rules to handle duplicates, and default values and migrate the data ?
Thanks,
Chak.
If your goal is to migrate data between two very different schemas you will probably need an ETL solution (ETL=Extract Transform Load).
An ETL will allow you to:
Select data from your source database(s) [Extract]
apply business logic to the selected data [Transform] (deal with duplicates, default values, map source tables/columns with destination tables/columns...)
insert the data into the new database [Load]
Most ETLs also allow some kind of automatisation and reporting of the loads (bad/discarded rows...)
Oracle's ETL is called Oracle Warehouse Builder (OWB). It is included in the Database licence and you can download it from the Oracle website. As most Oracle products it is powerful but the learning curve is a bit steep.
You may want to look into the [ETL] section here in SO, among others:
What ETL tool do you use?
ETL tools… what do they do exactly? In laymans terms please.
In many cases, creating a database link and some scripts a'la
insert into newtable select distinct foo, bar, 'defaultvalue' from oldtable#olddatabase where xxx
should do the trick
