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 would like to develop a ER diagram using DBeaver (Eclipse plugin) for a database that doesn't yet exist. Also, the database server doesn't exist.
Can DBeaver be used to develop a ER diagram without connecting to an existing database server? I can only find documentation for working with an existing database or connecting to an existing database server.
Nope, sorry.
DBeaver tools are always associated with the current connection.
For example, in the ERD when adding tables, DBeaver often sends requests to the database of foreign keys.
You can use standard sample SQLite database in DBeaver for experiments.
I’m trying to perform a Diff on two DB2 schema’s and when I try to select my source and destination connections it doesn’t list my NEW connection. I’m using latest version. I can connect to DB2 manually and query as well, but just can’t sect that connection during database Diff.
Where are the connections saved in sql
Developer?
That feature is reserved for Oracle Database connections.
DB2 connectivity is provided for migrations to Oracle only.
We have limited support for DB2 in the Data Modeler (which is part of SQL Developer), and you can compare models, but the generation of DDL synch scripts is reserved for Oracle data models only.
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 have got a sql file where is configured a database in PostgreSQL technology. I created a database from sql file but from code it is hard to understand action/connecting between the tables. Is it some tool which show all the connections between tables for PostgreSQL?
pgDesigner
Data Architect
Datastudio
DbDesigner fork
DbSchema
dbwrench
DeZign for Database
Please take a look to this list of tools.
Suppose I have multiple Oracle databases in the same server. Now I want to connect to particular database and query a table just like SQL Server 2008. How to start particular Oracle database?
If you are using SQL*Plus, the most common syntax for opening a connection is
sqlplus user_name/password#tns_alias
In this example TNS_ALIAS is the TNS alias for the particular database you want to connect to (most likely "XE" based on your followups to inium's answer). If you want to connect to a different database, you would need to specify a TNS alias for that specific database.
Note that since you are coming from a SQL Server background, the SQL Server definition of a database is rather different than the Oracle definition. What SQL Server calls a database is similar logically to what Oracle calls a schema (and similar physically to what Oracle calls a tablespace). So when you're dealing with Oracle, it's much more common to have many schemas in a single database than to have a large number of databases on a server. This is particularly true if you're using the Express Edition (Oracle XE) where you're generally limited to one database per machine.
go to cmd and type sqlplus <database-name>/<database-password>
You can use SQL Developer, it's similar to SQL Enterprise Manager 2005. Just create a new connection using the db user name and password.
