I am trying to connect postgres (postgresql 15) to Oracle SQL developer data modeler.
first Install the JDBC driver in Data Modeler
[1
then file-> import->data dictionary import ------>add
what should be in JDBC URL and Driver class?
I used this page http://tabdoelhafiezkhan.blogspot.com/2014/05/reverse-engineer-postgresql-with-oracle.html for filling the fields but it doesn't work for me.

We are moving on Postgres from Oracle EE, Currently we have SSAS cube connecting to Oracle for doing daily cube refresh.
Does any one know postgres driver to make is compatible source of database. Microsoft site does not mention anything about postgres database compatibility for multidimensional (MOLAP) project.
Multidimensional Models don't support PostgreSQL. Either copy the data to a SQL Server and build from there, or build a new SSAS Tabular model and use that instead.
I'm trying to connect to Denodo using Python SQLAlchemy, and create a DataFrame from a table. My environment is Cloudera Data Science Workbench. Can I use psycopg2 and the PostgreSQL connection string?
This won't work as Denodo dabbled with PostgreSQL schemas and is thus not compatible with it (or any other dialect). I use engine = sqlalchemy.create_engine("mssql+pyodbc://DenodoODBC"). DenodoODBC settings are taken from my ODBC Data Sources.
EDIT
In April, Denodo added a python connection guide:
Is there any feasibility from Oracle to have a connection established to DB2 database so that I can query on DB2 database and generate reports from Oracle Apex?
OR
Is it possible to create a View in Oracle from a remote DB2 database?
OR
What options do i have in order to develop reports in Oracle Apex from the data i have in DB2 database?
(I know, this is an old question and you've already found a workaround. Anyway,) the keyword you might be interested in is gateway. This is Oracle 10g Database Gateway for DB2/400 Installation and User's Guide. I don't know which database you use, but - if 10g is not the one, I hope you'll manage to find the right documentation.
Shortly: after installing the gateway between Oracle and DB2, you'd create a database link. Then, in your Oracle schema, create a view that selects data over that database link from DB2 database. Finally, fetch data in Apex from the view.
As i didn't find a way to directly connect to DB2 from Oracle PL/SQL, i used a work-around. As this is a reporting tool, we are ok to have this tool running with the data which is 1 day off, we did the following:
1) Extract the data required from DB2 database to CSV files. We used a DB2 command which can be run at command line to extract the data into a CSV
2) Then we imported the data into Oracle tables using sqlldr
I've Enterprise Architect v12 and I want to use its Database builder in order to create a live connection between it and a postgresql database.
This is what I've done:
I've downloaded and installed PostgreSQL 9.5
During installation I've installed with StackBuilder Npgsql v2.2.4.3-2 and psqlODBC (64 bit) v09.03.0400-1.
I've started pgAdmin III and I can connect to my local database. I've created a new one without problems.
I've created in EA a new project: in technology I've selected Database and Data model: PostgreSQL.
In DataModel -> Tables -> Tables I've added a table Table1 and I've created a column id (varchar and primary key)
In the same table I've added a Datatabase connection Database connection 1.
I double click on Database connection 1 and then I select ODBC based database. Then click OK
At this point I'm not able to select my postgresql database. The data origin window (I don't know if it's the right name I've the italian version of windows) gives me two tabs: File origin data and computer origin data. In the first case inside the postgresql data folder that I've selected during installation I don't find anything useful, while in the second case I can see only Excel files and MS Access Database. If I click on New button I can select the data origin only for the current user and in the list I can't see postgresql (SQL Server, Microsoft paradox, etc).
What I'm doing wrong? How can I read my posgresql database from EA?
Enterprise Architect only connects to 32 bit ODBC datasources.
You can access the 32 bit ODBC manager from within EA from Tools|ODBC Data Sources or directly in windows from c:\Windows\SysWOW64\odbcad32.exe
in icCube 5.1 there is no Redshift as list of supported JDBC connections.
How to create a data source in icCube on Amazon Redshift ?
A first solution is using the Postgres jdbc driver. Redshift is based on Postgres so it also works (for how long is a good question).
The second is a bit more complicated as you need to add Reshift jdbc driver to icCube. First download jdbc driver from amazon from here, after follow this instructions to add a library to icCube.
Once done you've to configure a new data-source :
