Is ti possible to exchange data between react-native and others apps?
I found Linking, but it only can send data to other application, I also want to get data back.

I would suggest some sort of Real-Time DB such as : https://firebase.google.com/products/realtime-database/
"Realtime syncing makes it easy for your users to access their data from any device: web or mobile, and it helps your users collaborate with one another."

I'm about to start working on a expense tracker app for mobile and I would like to use React Native with Expo (pretty new to mobile techs). Maybe I will share it with some friends or other people and the question that cames up is where to store their data (in this case is sensitive as they will register their money's movement).
What I mean is, I could use any cloud DB (Mongo, Firestore, etc) but I will have access to everything they register there and I wouldn't like that, just for security and their privacy sake.
So, is there a way to store their data or everything they register locally in their phones? So the app can only access to the data that is stored there and I can't see it. Or any other possibility?
I found the AsyncStorage API but I don't know if this is the correct approach for what I'm looking for. I didn't code anything yet as I don't know which would be the right path.
You can use Secure Store since you're using expo.
expo-secure-store provides a way to encrypt and securely store key–value pairs locally on the device. Each Expo project has a separate storage system and has no access to the storage of other Expo projects.
See https://docs.expo.dev/versions/latest/sdk/securestore/
I had a similar case and i went for realm.js .
I working on a project in which I’m facing a problem that I want to get real-time data from BigQuery dataset,
So I research hard I learn about web sockets like pusher and laravel-websocket, and I also test them also
but One thing I didn’t understand that how to do If I connect BigQuery SDK with my Laravel project then I didn’t find any event or method that BigQuery gives us to do so, because in my scenario most data comes from IoT devices and the device uses bigQueryAPI to feed data I also want that devices data real-time.
Then I found that there’s a way to connect BigQuery Dataset with firebase and then firebase gives us an event whenever row fed in the dataset.
I just want to know Is there’s any that without a firebase solution I can do it?
because the above solution is not free I have to pay firebase to avail of this feature?
thank you
IoT devices can post the data to pub/sub instead of BigQuery, from pub/sub one consumer(Ex:Dataflow) can read and insert the data into BigQuery and you can create consumer for your custom needs.
I'm writing an app that will let me manually edit my iTunes music library from outside of iTunes using a SQL-like syntax. I know how to edit the library, but I want to be able to run my track info against some kind of online database to get the right info. I found GraceNote, which seems to be the big name when it comes to music databases (iTunes actually uses it), but I'm not sure how to connect to their database. I registered into their developer program, but I'm not sure where to go from there. I just want to know where I can get a connection string and table info.
Have you tried Gracenote's Web API?

If you are creating an iOS or Android app, then you should use their Mobile Client SDK:

How does the Dropbox Datastore API differ from similar offerings like Parse? One difference that I see is that my users pay for server storage instead of me. Are there other differences?
Disclaimer: I'm a Dropbox engineer who worked on the Datastore API, and know about the Parse API only indirectly. Weigh my opinion appropriately. Major differences I know of (pro and con):
Dropbox Datastores are free to the developer, and free the user for the first 5MB per-app (after which their Dropbox quota applies). Parse charges developers based on how many API requests they’re making.
Parse has minimal offline support, while Dropbox has full offline operation. With Dropbox, if the developer modifies data while offline, those modifications will be reflected in subsequent queries (with Parse, those changes are not reflected). Dropbox provides on-device query logic (unlike Parse) so that apps can continue to generate the views they need to, even when there’s no Internet available. In addition, Parse does not provide conflict resolution or querying offline.
Parse provides the ability to share data between users, and global data for all users of the app. Dropbox Datastores only support per-user data (for each app) for now (sharing is on the roadmap).
I would also add that:
Parse is full feature of backend of as service. You can find a pretty complete list of the other player in this field: http://en.wikipedia.org/wiki/Backend_as_a_service. They provide feature like:
Data service
User registration/auth
Push notification
Social
The dropbox Datastore APIs is more focusing on data services. (You also got the User part for free too?) Also it works full offline.
The Parse framework can store data that can be ready by any user in the application.
The Dropbox datastore, store data for each user, and you can't accesss data from other user. That's the main difference.
So easy to get lost in this since you have to read between the lines. My take is that with Datastore you are working with objects stored offline locally as json. I'm hoping they will soon release a Xamarin Android component - they released an IOS component last month. Since Xamarin targets both Android and IOS and Winphone, who knows why they made a dedicated IOS DLL for Xamarin but I digress. With Parse, it appears to me their intent is the always-connected-device. Sure you can save queries locally and you can save (save eventually) locally where Parse will push to the server when it is connected. But saving "eventually" and saving queries for offline work is a different design than just saving and letting Parse do it all in the background for you - which it does not unless I have missed something that would make this attractive to me. I cannot see Parse useable for devices that you know will be sometimes-connected, without a lot of code to make this happen and sync.
I'm developing an internal iOS cocoa app, in which multiple devices need to connect and read/write to a data connection. It will be similar to an inventory application.
Would this be best done using a server-side SQLLite communicator or some other kind of server-side data store? Or is there a method i don't know of that multiple devices can share data.
Any help is appreciated. Thanks.
A third-party service possibly worth checking out is Parse.
With Parse, you can add a scalable and powerful backend in minutes and launch a full-featured app in record time without ever worrying about server management. We offer push notifications, social integration, data storage, and the ability to add rich custom logic to your app’s backend with Cloud Code.
Depending upon the complexity and assuming that all devices can be connected to the same icloud account you could utliize icloud for this.
