I wish to make fields in a remote public Sybase database outlined at http://www.informatics.jax.org/software.shtml#sql appear locally in our DB2 project's schema. To do this, I was going to use data federation, however I can't seem to be able to install the data source library (Sybase-specific file libdb2ctlib.so for Linux) because only DB2 and Infomatix work OOTB with DB2 Express-C v9.5 (which is the version we're currently running, I also tried the latest V9.7.)
From unclear IBM documentation and forum posts, the best I can gather is we need to spend $675 on http://www-01.ibm.com/software/data/infosphere/federation-server/ to get support for Sybase but budget-wise that's a bit out of the question.
So is there a free method using previous tool versions (as it seems DB2 Information Integrator was rebranded as InfoSphere Federation Server) to setup DB2 data wrappers for Sybase? Alternatively, is there another non-MySQL approach we can use, such as switching our local DBMS from DB2 to PostgreSQL? Does the latter support data integration/federation?
DB2 Express-C does not allow federated links to any remote database, not even other DB2 databases. You are correct that InfoSphere Federation Server is required to federate DB2 to a Sybase data source. I don't know if PostgreSQL supports federated links to Sybase.
Derek, there are several ways in which one can create a federated database. One is by using the federated database capability that is built in to DB2 Express-C. However, DB2 Express-C can only federate data from specific data sources i.e. other DB2 databases and industry standard web services. To add Sybase to this list you must purchase IBM Federation Server product.
The other way is to leverage DB2 capability to create User Defined Functions in DB2 Express-C that use OLE DB API to access other data sources. Because OLE DB is a Windows-based technology, only DB2 servers running on Windows can do that. What you do is create a table UDF that you can then use anywhere you would expect to see a table result set e.g view definition. For example, you could define a view that uses your UDF to materialize the results. These results would come from a query (via OLE DB) of your Sybase data (or any other OLE DB compliant data source).

Currently we are using Oracle 19c external table functionality on-prem whereby CSV files are loaded to a specific location on DB server and they get automatically loaded into an oracle external table. The file location is mentioned as part of the table DDL.
We have a requirement to migrate to azure managed postgresql. As per checking the postgresql documentation, similar functionality as oracle external table can be achieved in standalone postgresql using "foreign tables" with the help of file_fdw extension. But in azure managed postgresql, we cannot use this since we do not have access to the DB file system.
One option I came across was to use azure data factory but that looks like an expensive option. Expected volume is about ~ 1 million record inserts per day.
Could anyone advise possible alternatives? One option I was thinking was to have a scheduled shell script running on an azure VM which loads the files to postgresql using PSQL commands like \copy. Would that be a good option for the volume to be supported?

We have one last option that could be simple to implement in migration. We need to use Enterprise DB (EDB) which will avoid the vendor lock-in and also it is free of cost.
Check the below video link for the migration procedure steps.

I would like to create an automated data pulling from our PostgreSQL database to a Google sheet. I've tried JDBC service, but it doesn't work, maybe incorrect variables/config. Does anyone already try doing this? I'd also like to schedule the extraction every hour.
According the the documentation, only Google Cloud SQL MySQL, MySQL, Microsoft SQL Server, and Oracle databases are supported by Apps Script's JDBC. You may have to either move to a new database or develop your own API services to handle the connection.
As for scheduling by the hour, you can use Apps Script's installable triggers.
I've heard of a tool allowing to expose an ODBC/JDBC compliant database as a Postgesql database.
It was an opensource project on GitHub or Sourceforge. I'm unable to remember it or find it in my bookmarks.
Any clue ?
I'm assuming you need this because you have a pglib based legacy application.
In that case a work around might be to set up a gateway postgresql database, and then use the foreign server capability to connect via ODBC to the real target database.
You application would then talk to the gateway database via pglib, which would then in turn delegate the query down to the real database.

I have sql azure database and to create and edit database using portal is very boring task due to it' user interface, when i will connect it with my local sql server R2 then i can not able to edit , create table from there.
Is there any way to make it possible , Please give me some solution for that
At this time, the two options available are the web user interface (which will be improved over time) and SQL Server Mgmt Studio (using queries; no user interface) for which SQL Azure support will also improve over time.
After all i found one 3rd party client to manage SQL Azure and that is RazorSQL- Awesome tool! I have write down about it in my blog, see here

how i can backup oracle 10g like backup and restore in sql server ?
i want to backup tables and data
thank's in advance
Oracle has a comprehensive backup and recovery suite which is formally called Recovery Manager but is universally known as RMAN. Find out more.
The typical term for this is 'migrate' not 'backup'. You'll then find results in your favorite search engine to tools like:

If you only want table structures and data (no code), you can use SQL Server Integration Services (SSIS) package for this.
Read up here on the various methods and their associated speed

Oracle export data pump (expdp) is also good utility to take logical backup of your schema. You have very nice features with lot of flexibility in data pump. You can follow the link given below for further reading.
