I am a bit of a newbie when it comes to databases. Ive created a Nosql db on the IBM bluemix platform and I would like to access it from unity.
I was wondering if the www class would be sufficient to query the database? Would I need to add authentication etc? I can find samples for firebase and Aws with unity easily but I'm flying in the dark a bit with regards to cloudant
has anyone done this before?
The Cloudant database doesn't require any "drivers" or any special libraries to work with Unity. As long as you can make HTTP requests from your application, then Cloudant will be able to act as a data store.
You might want to try the Unity WebRequest object which is a lower-level abstraction than the 'www' library you suggest.
The Cloudant API Reference is here.

I want to create a Flutter mobile application and I want to use MongoDB Atlas as a database. Is there a Flutter package available that can help me with that?
If not, is there any other way I can connect Flutter to a MongoDB Atlas Database? If there isn't, what other options do you suggest?
Thank you in advance.
you can use the package mongo_dart, here is the catch in the database URL give URL to your MongoDB atlas database and you will be able to perform all the crud operations as usual. The documentation is pretty well written so you wouldn't have to face any pro
As #JideGuru said, what you'll want is some form of API that you can then make requests to from your app.
i.e. Instead of accessing your DB directly, you'd do something in Flutter like http.get("yourserveraddress.com/getSomethingWithThisNumber/1") using the HTTP package.
I'd recommend looking at something like Node.JS (https://nodejs.org/), which is a runtime for Javascript that allows it to be ran on servers. I'm just getting started with it and for basic CRUD (Create, read, update, delete) operations on my SQL database its been perfect. I'm not a JS developer by any stretch, but it is easy enough to pick up.
You really should never have your database being directly accessed by a client, as that means leaving it exposed on the internet!
MongoDB have their own driver for NodeJS, I've used it with atlas and it seems solid.

Hope this helps!
I have a web application that has to be linked with a graph database (Neo4J). Is it possible to read or write data to Neo4J using Appery?
I have chosen Appery because I am a beginner when it comes to databases and Appery seems to be easy in using REST API, as well as there is a free trial.
Feedback would be highly helpful. Thanks in advance.
Edit: I am aware that Neo4J uses Cypher queries. I would like to know if Appery supports Cypher as well.
Side note: The reason I am asking the question here without trying it out is because I dont have an active DB and my application is private due to my company's security policy
You can do that as long as Neo4J database has a REST API. If it does, then you can make calls to it from an Appery app (from Server Code or API Express). Hope this helps.
I am developing a hybrid Cordova app (but only for Android platform) using Meteor.
App should have offline support, in a way that a user can add objects that are stored offline, in a SQLite database, and after the user connects to Internet, sync the data with server (Mongo database).
Problem is a can't find any solution for synchronisation.
I have looked at GroundDB that provided the mechanism for synchronization I need, but stored data in localStorage which doesn't provide enough storage. In newer versions it doesn't provide sync mechanism, only cashing.
Do you have any suggestions or experience with this type of problem? Any help would be much appreciated.
You could look at LokiJS, which is in a high performance JS database, with features to sync to Mongo.
I haven't used it myself, but from looking at the site, it may do what you need. http://lokijs.org/#/
You can also check out MongOGX which is a Javascript "clone" of mongo for the front end
I'm Cococa programmer, but right now I encountered situation when I can't go any further without smarter people:)
I always used small databases in my applciations. I programmed PHP backend on my own server and it worked good.
Right now I have to switch for something much bigger and I decided to try with Google App Engine, because it is relatively cheap and has great scalability.
I'm so confused with documentation and I really don't know where to start.
My new app will store data (images, videos) as well as database (mysql) in google cloud.
I concluded that for app like that I should use:
Google Cloud Storage for images / viedos etc.
Google Cloud SQL for CRUD operations for users (inserting and fetching personal data)
I would prefer to use JSON api. Then I don't have to write any Java, Python or GO code, right? Only REST requests for Google Cloud SQL...
My question is : Am I thinking correctly? Should I use these two services?
Google App Engine has a feature called "Cloud Endpoints" (Java | Python)
that automatically generates a JSON API similar to the APIs that Google provides for its own services (and also generates client libraries in JavaScript, Obj-C, and Java to invoke those APIs), saving you the trouble of writing the REST API yourself and manually serializing/deserializing the request and, instead, focusing on just the business logic that performs the storage and retrieval operations. So, what I would suggest is that you write the code that reads/writes data into the datastore (and cloud storage), but then use Cloud Endpoints to automatically generate your JSON API and client libraries, rather than manually writing that code.
Your plan seems fine so far. Google Cloud Storage is a great choice for storing a large number of images and movies, and Google Cloud SQL is a great choice for handling smaller, more relational data.
If you're using PHP from app engine, there's built-in support for Google Cloud Storage. See https://developers.google.com/appengine/docs/php/googlestorage/
If you're using PHP from your app that lives somewhere else, you could write to the Google Cloud Storage JSON or XML APIs directly, but there's also a PHP library for the Google APIs that might be easier for you to use: https://code.google.com/p/google-api-php-client/
now I have an iPhone App and basically I want to exchange data from my database (MongoDB) on a server.
Could you please tell me exactly what I should do?
Forgive my innocence, I am a beginner in this area...Thank you very much ahead of time!!
I think you have two options to talk to mongo :
1) Use the rest interface http://www.mongodb.org/display/DOCS/Http+Interface
2) Use Objective-C driver: https://github.com/timburks/NuMongoDB
If you're not completely tied to MongoDB, have a look at CouchDB. It's essentially the same thing as MongoDB (JSON document store) but for the web. They have a nice built-in REST interface which makes database interaction in mobile/server environments very nice.
http://couchdb.apache.org/
In addition to Sid's options, you can also build your own backend that talks to mongodb, that communicates via REST (in your language of choice). This way you can pool your connections on the backend and avoid connectivity issues from the devices.
