Does facebook provide a way to store custom data for an app? I think of a user related store just like the users folder in operating systems. Performance should not be an issue as I can hold the data in memcache over a session but leave the persistent data at facebook so I don't have to store userdata on my servers.
There's no storage available on Facebook's server for your app to use. See http://www.facebook.com/help/?faq=100552270038780

I was wondering, if I create a share user entity on a Realm object server. If a user access to the database from his mobile. Could he see all the user data? I'm worry about sensible information on a shared database.
What do you mean by a shared database? All Realms are associated with a user, so yes, anybody with access to that users login information could see the data.
However, normally you would architect the app in such a way that shared data are kept in a shared Realm with the shared ID shipping with the app and then have a login that would generate a true user specific Realm.
Note in this context, it is very important to keep in mind there is a difference between an app user and a Realm Mobile Platform user. It is not uncommon for an app user to know about multiple Realm Mobile Platform user IDs.
I understand Realm is a Database Storage like CoreData. But I'm quite lost. After going through the documentation, I can't locate the tutorial for creating a login/register access to build for users. For instance, on Firebase, it gives you the tutorials for that, then provides you URL and other bits. Would I have to connect Realm with a cloud storage (like CloudKit) if I didn't want the database to exist on my computer?
I would plead for some sample codes to help me understand as I really want to use Realm.
I'm intent on building a social networking / messaging app.
Realm is a mobile database which persists data locally.
Would I have to connect Realm with a cloud storage […] if i didn't want the database to exist on my computer?"
So what you're asking for concretely is not exactly possible: the database will exist on the computer / mobile device all the time.
Beyond that you're responsible yourself for synchronizing your persistency layer with a backend service of your own choice. Realm doesn't offer yet any builtin mechanism for that.
On the addons page of our website, you will find in the section Connectors some components, which might help you with using a backend service.
I want to create an android application, I want my application data to be persistent. There is a file that I want to save every time to the Bluemix server.
I want to confirm the following, for a situation in which a user "A" from my application saves the data to the IBM Bluemix Server, and if there are more than 2000 users saving the same user-related file in the server:
Will there be any differences between all the different user files?
Will there be any collisions?
Will I be able to differentiate the
files of other users?
Will I be able to save and retrieve the saved
file of only that particular user?
Thank you.
Using the Mobile Client Access (MCA) service you will be able to do exactly what you ask.
MCA can provide you with a unique identifier for each authenticated Facebook, Google+, or custom style user, enabling you to manage your data appropriately. I recommend the Cloudant NoSQL DB service for fast and easy database management.
See the MCA docs and Android sample for further information.
I am currently developing a mobile app using the Corona SDK and Lua. I need to store information about each user and load the information for the current user when they load the app. What is the best method to store this information for each user, and how would I get this data on app load. I was thinking about using sqlLite and having a single row for each user. However when the user re loads the app I would have no way of accessing the data for the current user because when the app loads I would need something to index the database. Is there any way I can get some information from the mobile device on app load to index the database? Any ideas or suggestions?
I'm not clear on where the database is stored.
If it's remote on a server just use the device ID
system.getInfo( "deviceID")
If it's local and you have multiple local users then use a login.
You could use a registration process for either instance and store
The registration keys for automatic access when launching the app.
take a look at amazon's services.
like S3,simpleDB, dynamoDB..
Some implementations are already available in Code Exchange

in Google App Engine,after using the makePersistent() to store the data in the datastore,i know how to get the data content by the key using getObjectById().
but now i wanna to get the data in the datastore by url. i think the url is created .
so the question is how the url can be created to get the data in the datastore
There is no built-in means to access the datastore through URLs. If you choose to, your application can implement URLs that return data from the datastore.
I invite you to take a look at titan-files. It's a powerful file-system abstraction on top of the DataStore and/or blob store. I'm using it for a commercial application and so far I've been very happy with it.
