I am trying to implement the Aspera cloud object storage using ATS API in .NET.
Is there any way to retrieve the cloud API object to retrieve using C#?
While going with the IBM documentation there is only support for Java and python.
I would suggest the fllowing:
look at: https://www.rubydoc.info/gems/asperalm#ibm-cloud-object-storage
This will allow you to transfer to COS using command line and Aspera
analyze the code, it is relatively sumple (cos.rb)
use IBM Aspera "Transfer SDK" you can find here:
https://developer.ibm.com/aspera
write your own code for the REST calls part, and use the Transfer SDK once you have built the "transfer spec" to start the transfer.

I searched how I can upload file to oracle OCI and I know its S3 compatible but I don't know what the SDK I can use? any example for upload file to oracle OCI by c# .net core 5.
I received info for oracle OCI from client like (storage_endpoint,storage_access_key_id,storage_secret_access_key ,region and bucket_name)
AWSSDK.S3 for C# is not compatible with Oracle.
The only supported clients SDK are Java, JavaScript, and Python.
Furthermore, you can't use storage_endpoint, storage_access_key_id, storage_secret_access_key with the OCI object storage client.
I do not know this Oracle product but if it truly is S3 compatible I would suggest using the AWS SDK (AWSSDK.S3 on NuGet).
There are many tutorials on how to use it, I don't think posting a guide here would be more helpful. If you encounter specific problems then please do ask further questions.
I want to create my own MongoDB driver but I don't find any document to connect to MongoDB server(like docker container) without exist drivers.
If it has socket, how to speak with that ?
If it has api, where is document ?
Or I should to use C shell driver ?
You have to implement the MongoDB Wire Protocol. If any language implements this protocol then it's able to communicate with a MongoDB instance.
Microsoft did the same when they created the former DocumentDB to keep compatibility with MongoDB.
By the way, the Mongo Driver source code is also available, so you can learn a lot from it. Link: mongo-csharp-driver
I'm also thinking of implementing the same solution because I found something unfriendly in the driver. Please leave a comment what your purpose is for implementing the protocol.
We have an emerging need to modify the schema in our Agile Data Warehouse including adding new tables. We've been able to manually connect to the ADS database using Squirrel SQL and CloudConnect.
However, we would like a way to automate this process so that we can ensure that the schema remains consistent between our development, test and production ADS instances.
We're a .NET shop and most of our code is in C#. Has anyone had any success connecting directly to ADS using .NET (C# or VB)?
I've looked at trying to use the GoodData JDBC driver but it looks like referencing a JDBC driver from .NET is not particularly straight-forward and there is not a GoodData ODBC or ADO.NET driver available.
I'd rather use something like the Vertica driver for ADO.NET available at https://my.vertica.com/vertica-client-drivers/ however, I'm not sure what to use for all of the connection properties. I've attempted to connect using the Host and Port that are returned from the DW connection endpoints API but receive the following error: "SSL Startup Failed." when using the Vertica ADO.NET driver.
Is there a way to connect to the GoodData ADS daatabase using .NET or any better approaches to modifying the ADS schema using a CloudConnect graph or REST API?
Any advice would be appreciated.
GoodData currently provides only a custom JDBC driver for connecting to ADS. Standard Vertica drivers cannot be used. See https://help.gooddata.com/display/doc/Data+Warehouse+Technology
It is not possible to use the JDBC driver in .NET for obvious reasons. Theoretically it could be possible to use a ODBC-JDBC gateway, but I have not tested this solution. Also there is JVM implementation for .NET, but I have not tested it also. It is http://www.ikvm.net/.
So the easiest way is really to use CloudConnect or a SQL client which supports JDBC drivers. For automating a process the easiest ways are probably Java or JRuby.
I am writing a plugin for an application in C#. The plugin allows me full access to the internal information model for the application.
I would like to create a mechanism to allow external applications to be able to connect to the information so they can report on it etc.
In days of old this used to be achieved via ODBC links - is that still the way to go.
I assume it's a significant task to create an ODBC driver for this, are there any easier recommendations or example C# code for cresting a driver.
Looking back I was not very clear in the original question. The requirement is to allow two applications on the same PC to share data. The "host" application use a proprietary storage format and as such access to the data cannot be achieved without using the "Host" application. The "host" applications allows the development of plugins (using C#) and the plugins have access to all of the data within the application. On that basis I was exploring whether a plugin could therefore expose an interface to an other external application and as such could act as a "Data Access Layer"
My reference to ODBC is probably a "red herring" - just shows how out of touch I am in this area.
Probably you are looking for something like Remoting and\or Web Services and\or the more modern WCF (windows communication foundation).
You can write your own services and access to that services from every language you want.
C# support for WCF and Remoting and WebServices is very good and allow you to write your server-client infrastructure in a very clean, object oriented and easy way.
Use HTTP: each services is handled in a serialized object sent in XML through an HTTP server, for example, IIS.
Clients can be written in every kind of language you want, from PHP to C# to C++ to JAVA to wathever, they need only to connect through HTTP and parse\deserialize\serialize XML.
You can choose your architecture. If both clients and servers are written in C# all is transparent to you, serialization and deserialization of XML, remote procedure call and IIS integration are all ready for you to use. You need only to write your applications.
You can export services instead of tables like a relational DBMS does, in this way you can divide the logic of your system from the data layer and the presentation layer.
In this way you can obtain scalability, multiplatform and multisystem support.

Instead, if you are in an intranet, for example, or a single computer and you want just to share a DB service, you can just use SQLServer or MySql or PostgreSql and connect to it via TCP/IP.
Is not safe\secure however to expose a DB service on internet or in an intranet where security can be a problem.
Note also that SQLServer Express is free and may be suitable for you if you don't have much users\connections or a DB not greater than 4gb.
MySql and PostgreSql are free and open source.
I'm in the initial phase of designing an application that will have a backend implemented in C# that will provide data for other platforms using WCF web services hosted on IIS. One of the platforms will the the iPhone.
Since it's a personal project, I want to use it to learn MongoDB. I already know that there are community developed drivers for MongoDB and C#, so I could handle the persistence on the server side using MongoDB.
Without even knowing the replications models offered by MongoDB, I was thinking about some kind of simple synchronization model to keep data local if the iPhone is not connected or has a poor connection.
Here's the question: Can MongoDB be used in the iPhone using the MongoDB C drivers? Has anybody already tried that?
The typical iPhone architecture is to have your application call out to a web service. Even if it is possible to use a MongoDB driver directly from a mobile client I would not recommend it. For a few reasons.
You are basically talking about doing client server architecture where your client application talks directly to the datastore (MongoDB.) What about security? When any authenticated client talks directly to the datastore all sorts of bad things can happen.
Tightly coupling your client application directly to any given data access technology is dangerous in that it would require you to rewrite your client if for some reason you needed to change your data access solution.
It is more common these days to have your client applications go through a data access tier and when the Internet is involved this tier often involves a web service of some sort unless you want to get elbows deep writing server code.
Think about writing a RESTful api exposing your datastore to your iPhone client. I've heard good things about Open Rasta (C# REST library)
Edit - More about hosting MongoDB on the iPhone
Sorry I didn't understand that you wish to run MongoDB locally on iPhone. MongoDB is a server. I do not believe that it is embeddable as an in-process datastore. And it is not possible to run more than one process on the iPhone.
If you are familiar with C# you might want to check out MonoTouch. It allows you to run C# applications on iPhone. There is a nice library for using SqlLite which is supported by iPhone.
