I have created an application on Bluemix. I need to copy my database on Bluemix that can be accessed from my adapter. Can anyone give me detailed steps on how to proceed?
First thing: if your database is reachable through the Internet and you only need to connect to it from the application, please note that a cf application on Bluemix can access the public network and so it is already able to connect to your DB in this scenario.
Assuming that you have a requirement for migrating the DB on Bluemix, you didn't specify which kind of database you want to migrate, here are the main (not all) possibilities you currently have:
RDBMS:
PostgreSQL by Compose (you need an account on compose.io)
SQL Database (DB2, only Premium plan available)
ClearDB (MySQL)
ElephantSQL (this is basically a PostgreSQL as a Service - that is you have to work on the db via API)
you could use the RDBS capability of dashDB
No-SQL:
Cloudant (documental)
Redis by Compose (ultra fast key-value db. You need an account on compose.io)
MongoDB by Compose (you need an account on compose.io)
IBM Graph (graph No-SQL db)
I suggest you to take a look at the Bluemix Catalog (subcategory Data and Analytics) and to refer to the Docs as well.
You can create dashDB service on your bluemix, and copy / upload your data to Bluemix dashDB database, using dashDB VCAP Credentials to connect to it from your adapter, or you can bind your dashDB service to you application on Bluemix.

I am new to Azure and have no prior experience or knowledge regarding working with Azure data warehouse systems (now Azure Synapse Analytics Framework)
I have access to a "read only" data warehouse (not in Azure) that looks like this:
I want to replicate this data warehouse as it is on Azure cloud. Can anyone point me to the right direction (video tutorials or documentation) and the number of steps involved in this process? There are around 40 databases in this warehouse. And what if I wanted to replicated only specific ones?
We can't do that you only have the read only permisson. No matter which data warehouse, we all need the server admin or database owner permission to do the database replicate.
You can easily get this from the all documents relate to the database backup/migrate/replicate, for example: https://learn.microsoft.com/en-us/sql/t-sql/statements/backup-transact-sql?view=sql-server-ver15#permissions,
If you have enough permission then you can to that. But for Azure SQL datawarehouse, now we called SQL pool (formerly SQL DW), we can't replicate other from on-premise datawarehouse to Azure directly.
The official document provide a way import the data into to Azure SQL pool((formerly SQL DW)):
Once your dedicated SQL pool is created, you can import big data with
simple PolyBase T-SQL queries, and then use the power of the
distributed query engine to run high-performance analytics.
You also could use other ETL tool to achieve the data migration from on-premise datawarehouse to Azure. For example using Data Factory, combine these two tutorials:
Copy data to and from SQL Server by using Azure Data Factory
Copy and transform data in Azure Synapse Analytics by using Azure
Data Factory
What's the backend database query of this Microsoft Dataverse Analytics dashboard?
I'm trying to workaround Dataverse analytics by accessing the transactional database behind that dashboard, I'm interested in getting Daily Active Users (DAU) shown above but via a SQL query and reading directly from the backend database.
It appears that the DB is this https://learn.microsoft.com/en-us/dynamics365/customer-engagement/web-api/entitytypes?view=dynamics-ce-odata-9 but I have not been able to comprehend the data model and I'm unable to find the tables to get DAU. Any thoughts?
Thanks
Basically you have to do everything what is MS doing in behind the scenes. CRM online is SaaS model and we don’t have access to Azure SQL server directly. But what you can do is, one of these options:
Use “Data export service” to replicate the data to your own Azure SQL server, then build Power BI on your own from the data
You can use REST Web API to pull the data and visualize (May not be so much flexible)
Based on your need and urgency, you may wait or use preview version of TDS endpoint, for read-only direct SQL access. Read more
I'm in the process of migration from dedicated servers to Azure. In my existing SQL Server, I have a few jobs that move data from live database to archives.
From what I have read so far, in Azure you cannot use cross database scritps. The other options I have seen include Azure SQL Data Sync, Azure Factory and maybe SSIS. I have to note that there's some logic on what data is archived and I need the ability to specify this in the query.
Has anyone some experience and what would you recommend?
Thanx
You can use the copy feature inside of data factory to do this now directly in Azure.

I am a new user to openstack trove. As far as I found (from the process of creating datastore and database in trove) trove works like this: For each datastore instance there is a nova-compute image that this instance will be launch on that (and also a cinder storage assigned to this instance) Therefore there is not a centralized database which could be manage by openstack administrator. As far as I know there are two types of cloud database: 1)virtual machine image database and 2)dbaas. For dbaas it should not be like having a virtual machine instance per each database and database provisioning should be manageable by system administrator (not client). Therefore could somebody explain for me how trove works and how could we consider it dbaas and not virtual machine image database?
Regards.
Trove is an openstack service that provides an API for creating a relational or non-relational database to a user. This database can be used within a deployed application. So in your terms it is a database as a service solution.
Trove provisions an instance from an image for a single tenant. This is not meant to be a centralized database for openstack.

I am working on a phonegap project to build a cross platform mobile app, and came to know from a website that the app's database can be deployed/built with "database.com".
The procedure is well explained but I have one question -
how to sync the database available on database.com with a database on a local server?
i.e. for e.g., if a client has his database (of his desktop application) on his local server and he requires a mobile app of the same now, what is the procedure to be followed in "database.com" to sync his server's database with the database on "database.com"?
PS: I need to use "database.com" for my database because I want to maintain it on cloud, and I do not have capability to maintain a local server.
You might need a service for data syncing if it is to be more than once. I work on a project that does exactly this.

Otherwise, model your tables to Salesforce Custom Objects, export the data on the local server to CVS and use the Data Loader to import.
