We are using OpenMRS in Amazon EC2 .Can the Parse.com to make only notifications database or The Entire database to be build on Parse.com.
If it is So.We will be using the Google Messaging Cloud.
Parse's push offering can be augmented with other features (i.e. advanced targeting based on relationships with users or other data stored with Parse), but it is designed to work as a standalone feature.

I am currently developing a full-stack web application for the first time. It is a store that needs to give users the ability to upload "books", edit, delete, and manage them. As of now, I have a React front-end, that calls an Express API using Axios that queries a MySQL database. This currently can manage the product details, titles, and simple labels and relations.
However, I now need to store images and .json files dynamically as well. So, I have researched and need to use Azure Storage to store these images and allow access to them by the end-user. I have researched it and the client would like to use Azure storage as well.
I have gotten quite overwhelmed looking into the Azure documentation for Javascript image uploading, and every "tutorial" starts with create a web application, storage account, and app service.
All I would like to do is store images from the user in Azure storage, so that when I eventually deploy the website, the data is available to be accessed and then my front end or API can call Azure to get the images for the user. I apologize if the question is confusing or vague, I am really just overwhelmed by Azure's documentation and it seems like such a simple and common problem. Any guidance or references would be greatly appreciated.
Yes, it's quite possible. You simply create an Azure Storage account and upload your files as blobs via that account. Then they will be available publicly on the Internet, and your web application can reference them from wherever it is hosted.
It is possible as I believe it is quite a common practice to have a Content Delivery Network to deliver the images. I am not very familiar with Azure but I am with AWS and I can tell you that you can use an AWS S3 bucket to store the images and JSON. It comes with many different configuration options to allow content to be protected or open to the general internet.
I have just created a Project in Google Cloud, and attached a Cloud SQL Database instance to that project. I was able to deploy a Django app that is connected to that DB just fine.
However, I would like to create a separate Django app/Project that is attached to the same Cloud SQL Database that my first Django app is attached to.
Is this possible?
One Django app is responsible for web scraping and supplying constant data to the database while my second Django app (the one I have already deployed) analyzes and returns json on that data. It would be advantageous to separate the two apps because if I ever needed to revise my web scraping algorithm, the whole app would not be down.
You can use cloudsql proxy for both apps. Also as long as you authorize both of your applications with service account that have access to the cloudsql it should be fine.
You can use database that you want, in your current project or in an external one. If you use Cloud SQL proxy, the service account of your app
Either Default AppENgine service account if on App Engine
Or Compute Engine default service account
except is you have defined a specific service account on your component (Cloud Run, Compute engine)
I recommend strongly to use a specific service account on the component if it's possible (not possible with App Engine)
The role to grant on the service account is the following: roles/cloudsql.client
However, I recommend you to smartly think to your design. The current trend is to lock 1 database to 1 service (or microservice).
Think about the schema update: a synchronous update will be required between to 2 services when you update the schema or one, or the other app will fail.
Same thing in case of rollback, both apps need to be rollbacked.
If there is 2 teams, one on each app, their release planning must be sync, and you will lost in velocity and agility.
Maybe, it fits your requirement, or you can duplicate the data, inside the database (other schema). As you wish.
Is it possible to use two databases, example, Firebase and an online webhosting server? I am developing an app that uses the webhosting server for the data and the firebase only for the chats.
Absolutely. Firebase is very flexible when it comes to picking and choosing parts which you want to use.
You don't need to migrate away from whatever backend you already have if you just need to add in something that is unrelated to your site data, such as a support chat or something.
Instead, see it as an opportunity to discover Firebase by trying out something isolated like a chat using Firebase Database. You'll find your best fit by trying out the strengths and limits of the platform.
Yes it is Possible but, you have to manage the back-end accordingly. I have created the app in which api is hosted in aws-EC2 and few part is in the Firebase. For example for some live changes I'm using the Firebase and for other things like getting feeds and all those thing i used aws EC2.
We would like to hook up an iPhone app directly to a database in the cloud. From the iPhone app, we would like to use some REST API to retrieve data from the cloud database. We prefer using MySQL or Mongo as the data store.
We prefer not setting up our database system on AWS or another hosted provider. We would like a cloud service that offers the database layer out of the box.
What database-as-a-service companies support this, and what are the pros/cons of each?
We looked around, and it seems like MongoLab is the only service offering a REST API.
Mongo is a great database for API interaction as the query language uses javascript expressions. Here are the open source API libraries that are implemented in Python
Sleepy Mongoose
Eve
Primary advantage
JavaScript can handle the querying part of data retrieval
Primary disadvantage
The API libraries above have difficulty capturing complex queries
I am developing an education app for Kids.
The application is going to contain pictures, stories and video as well.
Including all above contents in the app will surely bloat it and hence i would like store all data on a server that will be accessed by my app.
I haven't used any remote databases (like MySQL or Oracle) with any other iOS app. In fact i am a newbie in developing such kind of apps. Can any one point me to a sample
Connecting to a remote mysql is really not recommended.
The security here is critical.
You should create a webservice and my advice to you is to make sure that the access to the webservice is restricted
The webservice can be your own "protocol" or any other well known protocol like SOAP
By your own I mean, json, csv .... or whatever.
Edit 1
The technology of your webservice should be dependent on many things.
If the system is small, and the code needs to be update very often, I would suggest to do it with PHP and some small(!) MVC framework like CI.
But if its a large system with needs of ACL (access control list) I will probably choose java with spring...
I suggest that : Do not connect to / use database directly from user application. It may causes serious security problems and your app should have native SQL drivers to connect db.
So, create a web service that receive queries from the application and response in XML, JSON or some other strings that easy to parse. This will be much easier than embed native APIs into your apps.
