I want to connect to a Cassandra Database from my Delphi application. I found that there is a DataStax OBDC driver. But I didn't found any examples explaining how to connect Cassandra Database from Delphi using ODBC driver.
How to connect Cassandra database from delphi using this ODBC driver?

In order to connect to an IBM DB2 database, I am using DBeaver with an ODBC type of connection. But since I found Azure Data Studio very lightweight and portable, I want to ask if there is a way to connect to such databases because all I get is Microsoft SQL Server as connection type.
I'm trying to change the protocol from bolt to bolt+routing in the Kafka Neo4j Connector configuration. However I'm facing the error

After reviewing somethings and I get confused on Neo4j Drivers. Currently there are 2 neo4j driver: Neo4j JDBC Driver and Neo4j Java Driver. I only see Neo4j JDBC Driver supports bolt+routing, but the Neo4j Java Driver doesn't. I see Sink Connector is using Neo4j Java Driver, wondering how we can use bolt+routing in Sink Connector.
TIA
I am developing an application in Delphi 10.2.3 which connects to a Firebird database installed on a machine running Windows 2016 Server. The application also connects to QuickBooks Online using a third party ODBC driver. Since this application must be accessed by 12+ users in my company, it will not be cost effective to purchase and install individual ODBC drivers for each user.
The provider of the ODBC driver has a version which can be installed on a server. Is it possible to configure an ODBC DNS connection on the server which I can access from network clients? If not, can anyone suggest a workaround.
Server vs Workstation ODBC driver usually has to do with licensing not connection method. It is always running on the same machine as the software using the connection.
Web application used by many users running on a server connecting through an ODBC driver = server licensed version of the driver.
User loading data into Excel on their computer through an ODBC driver
= client / workstation licensed driver.
Some databases, for example SQL Server, can do a database link through an ODBC driver. This is linking / exposing another database to querying from a host database server. This would allow you to share one server licensed driver. The clients would connect to the host database.
One such driver is DevArt's ODBC Driver for QuickBooks which has a help topic on creating a linked database and testing it in SQL Server Management Studio / SQL Server: Using in Microsoft SQL Server Management Studio (SSMS). Might not be applicable if each user needs to use different credentials for the QuickBooks connection.
I have an asp.net application running on Visual Studio in Windows; my data is on Hadoop on Linux. How do I connect these? Is there any web service on Hadoop?
You may install hive and query through hive.
Use the System.Data.Odbc.OdbcConnection class with the Hive ODBC driver to query Hive tables in the HDInsight cluster.

I have to connect my app to a customer's Informix 7.2 legacy database.
From what I was able to find out, in theory there should be a database service running on port 50000. The problem is that I cannot find any database service in the Operative System.
So far I'm only able to use dbaccess and perform queries from the command line.
I would like to use a database driver (such as http://code.google.com/p/ibm-db/) so my app can connect and query the database using a cursor, but since I cannot find any database service, apparently I can't...
Am I missing something here? Are there options I'm not considering?
Is it possible to have an Informix database in which the only interface is dbaccess?

If you use Python you can look at: Python wiki but I would like to extend it a little.
If you work on Windows and have Client SDK then there should be ODBC driver installed on your machine. There is also Linux and other unix versions of such client software. If you install that you can use ODBC to connect to database. On Windows you can use Active State Python 2.6 with win32 extensions which has odbc module included. On other Python implementations you can use win32 extensions or other ODBC module such as mxODBC.
I work also with Jython where I use both JDBC and ODBC drivers. You can see this "in action" in my SO questions like: Problem with Informix JDBC Money format
BTW, if you want to connect to a remote legacy Informix database using Python from a Mac, pypyodbc-informixcsdk could be your only (free) choice. Check this wiki.
On a Windows box, pyodbc + Informix Client SDK + ODBC do the job nicely.
