Expose cobolfiles db using webservices or API - api

I have to expose data of an old application through webservices or API for manage data and interface a new python app whit it. I know that is a COBOL application, i found this documentation:
Introduction to COBOL Web Services
I don't have experience with cobol; someone can guide me through the best choise for expose cobol data using webservices for example?
So many thanks in advance

Server Architecture .net/cocoa app

I'm planing on creating an native .net app for Windows as well as a native OSX application with swift.
These two applications should be able to communicate with the same server. With that I mean writing and reading from the same SQL Database, and have REST communication with the server.
Now I'm struggling to come up with a solution for the backend. I'm looking into Serverless backends like Azure or Google Cloud, but I'm not sure that I can use these Services with both my applications. Both Azure and Google Cloud have SDKs for .Net but I've never found one for Swift or Objective-C.
Are there such Services that allow me to communicate or should I just develop my own?
Do you have any good solutions for my problem? Or what is the best server architecture to use for this kind of problem? Any inputs are appreciated!
If your servers vend a REST API, no vendor SDKs should be required. REST is platform- and vendor-agnostic. All you need is an HTTP client, which Swift/ObjC most definitely do have. I use a serverless (AWS Lambda) setup from Swift, and it's easy. Though, I have done this kind of thing before :)
What I would do is setup a simple test server, and expose an API endpoint. Make sure you can reach it with curl from your machine. Then, take a look at the NSURLSession APIs in Foundation. They'll help you make an HTTP request similar to what curl can do. From there, you'll need to investigate serialization (like JSON), which Swift can also do easily (as of Swift 4, I believe).
Good luck!

Generating documentation for a Datasnap RESTful API

I've been looking for a way to include an auto-generated documentation endpoint to an existing Delphi Datasnap RESTful API.
Can it be done? Are there annotations or external tools I can use?
Where would I begin, how would I proceed? If not from within Delphi itself, can I integrate with e.g. Swagger?
It seems somewhat anachronistic to build a RESTful API without offering a documentation endpoint these days...
Any and all information that could help me in the right direction would be greatly appreciated.
Using Swagger, via YAML has just been added to Delphi through EMS, the latest RESTful API development option in Delphi.
https://delphiaball.co.uk/2016/04/22/swagger-yaml-delphi/
Its based on Attributes that are added to the API end points as they are defined and that in turn creates the YAML to import into Swagger.

Is there any solution for generating the restfual api code both for client and server

The functions for operating the restful api is quite same. Is there any project that can generate the source code for different platform such android,ios and backend stuff.
I suggest you to use API description languages such Swagger ou RAML.
After having described your RESTful application with a language like this, you will be able to generate things like server skelekons and client sdks with different technologies and languages. You can even generate documentations.
With Swagger, swagger-codegen will do that. swagger-ui may also interest you for the documentation part.
To finish, I would like to mention the Restlet studio that allows to define graphically and quickly the structure of RESTful applications and generate then the corresponding Swagger and RAML contents. The APISpark plaform provides a mecanism to introspect Restlet applications and generate the corresponding contents with these languages. It also allow you to generate a set of server skelekons and client sdks.
Hope it helps you.
I will suggest you to use Spring RESTful webservices starter kit. Which will manage your back-end with centralized database. Also Spring has its own android libs to communicate with REST Apis.

Is WCF the way to go for a RESTful webservice in MS environment

I want to learn doing RESTful webservices. I have surfed the web some hours and think that I have a good overview over what RESTful services are and now want to build my first service-application. I have a good small project that seems perfectly suited for doing it with a RESTful webservice.
I have seen that WCF has the ability to build RESTful webservices. My question is, if it is reasonable and efficient to write RESTful webservices with WCF or if there are better suited alternatives for writing such services in the Microsoft programing environment.
(As additional information, I already have experience in using WCF, but more in using it in a RPC-way. But I don't think that this is important for my question anyway).
WCF supports RESTful services via the webHttpBinding. This works but doesn't give you alot of control for working with the HTTP protocol itself (although some things got better in 4.0)
The next version is going to have a lot more support for RESTful services. The team are being very open about the new Web API so if you are not about to put something into production then I'd start with the new API
WCF is perfectly valid and very capable of handling REST services - you won't go wrong with that!
And there are a couple of alternatives out there, too - check them out and see which one suits your needs best:
RestSharp
OpenRasta
RestDotNet (clients only)
and probably quite a few more....

Can you use JIRA's SOAP API in a VB.NET desktop application?

I tried using JIRA's REST API but the function that I needed wasn't there and found it at JIRA's SOAP API. A newbie like me wants to know if you can use JIRA's SOAP API in a VB.NET desktop application? Thanks!
Absolutely. The point of a SOAP service is to allow access to the data and functionality of application from another application regardless of the language it is written in. All you need is something in your program that understands how to talk to and work with a SOAP service.
I have no doubt that a VB.NET application can talk to a SOAP service without issue, but I am not a .NET programmer so I can not provide any specific guidance on how to do it.
What you will want to search for is "Consuming SOAP services with VB.NET". I did that myself and came up with some god looking tutorials.

Like I said, I think everything you need will be built into the .NET framework. I don't think you will need to download anything additional or include extra libraries.
