I'm using an application that uses Postgresql on RDS, and I use Entity Framework.
What if I migrate to Amazon Aurora Postgresql, should I have to change my application? Or only the connection string?
Will the provider continue to work?
Will it affect my application? Thanks a lot.

I have an existing java springboot application that uses springDataMongo api to connect to an underlying Mongodb instance.
I need to use the existing springDataMongo api classes but instead of Mongodb, I need to connect Cosmos Db.
I have looked it up on documentation for azure Cosmos db api for Mongodb but didn't get hold of what I am trying to do.
Can someone let me know if what I am doing is possible and if yes, point me to a relevant documentation for the same.
Yes, it is possible to connect to Azure Cosmos DB MongoDB API using springDataMongo.
What you need to do is copy the Cosmos DB connection string from the Azure portal and then put it into spring.data.mongodb.uri in application.properties file of your spring boot project.
application.properties
#mongodb
spring.data.mongodb.uri=mongodb://[username]:[passowrd]#[cosmosdbName].documents.azure.com:10255/?ssl=true
spring.data.mongodb.database=[dababaseName]
After that done, you can check this guide out: Accessing Data with MongoDB.
I am new to Bluemix. I am planning for a web application that could utilize the database service and Watson IoT service.
Currenlty I am using mysql for my app, because it is more familiar to me. I have noticed couple of other services too( clearDB, dashDB, Cloudant DB, NoSQLCloudantDB ). I am not sure whether all the terms i mentioned is correct.
I am confused, which service should i follow?.
For mysql, How can I see the tables that I pushed?.
And, what is meant by, cloudantNoSQL?.
Thanks for the help!
The Watson IoT platform provides a managed connector to the IBM Cloudant NoSQL DB service on Bluemix. https://developer.ibm.com/iotplatform/2016/07/25/enhanced-data-storage-capabilities-for-ibm-watson-iot-platform/
A single specific storage solution is not going to work for every case so which option you choose may be dependent on your overall architecture and strategy.
We have a data source accessible from an XML RPC web service where we can send CRUD commands.
Is it possible to use this with EF ?
No unless you write your own provider. EF has very limited set of providers available. All these providers targets relational databases.
I'm considering using WCF Data Services to implement a service exposing objects stored in the Azure Blob Service. I wonder if I could use a data model based on the Entity Framework. As I understand, I would need a data provider compatible with the Entity Framework that could store and retrieve data from the Blob service. Is there such a data provider?
There isn't a data provider for Azure Storage that is compatible with Entity Framework. Creating such a data provider is probably not worthwhile because it's a very complex project and because Entity Framework is not a good match for Azure Storage's conceptual model. Entity Framework is designed for relational databases and Azure Storage is REST-based non-relational storage.
As for creating a WCF Data Services layer over Azure Storage, it could be built using WCF Data Services Toolkit.
