I am relatively new to Firebase Database. I initially designed our Xamarin App using SQL as Server database. After analyzing cloud costing, i will have to move on Firebase.
App will have List view with Images, Map Coordinates and other details. Do firebase has any limitation on storing the data ? Whether images are stored in the firebase database? Whether there is a way to view the data in firebase database as similar to working on Management Studio?

I am using the Azure web app with PHP 7.3 stack. In my project, we have the feature to sync from mobile to web and for that, we are using the SQLite file. And for other modules, we have a MySQL database.
The mobile app sends the SQLite file and we stored it in the directory. But we try to make a query to the SQLite with PDO then it throws the error that the database is locked.
I tried many solutions from the other's answer but not get success.
This has to do with permissions of the underlying storage mount.
One option you could try is mounting an Azure File share and persisting the database there, see https://learn.microsoft.com/answers/answers/320889/view.html. The best option however is to utilize a cloud database such as Postgres or MySQL for Azure.
My problem:
I need a data pipeline created from my organization’s Oracle DB (Oracle Cloud Infrastructure) to an AWS S3 bucket. Ideally, I would love for there to be some mechanism for oracle to push new data that has entered the database to be pushed to an S3 bucket as it is added (in whatever format).
Question:
Is this possible with Oracle native, specifically Oracle Cloud Infrastructure?
Or would is there a better solution you have seen?
Note:
I have seen AWS has the Data Sync product, this seems like it could facilitate with this problem, however I am not sure if it is suitable for this specific problem.
An S3 bucket is object storage; it can only hold complete files. You cannot open and update an existing file like you would in a normal file system, even just to add new rows. You will need to construct your whole file outside of Oracle and then push it to S3 with some other mechanism.
You may want to consider the following steps:
Export your data from Oracle Cloud into Oracle Object Storage (similar to S3) using the Oracle Cloud's integration with their object storage. (https://blogs.oracle.com/datawarehousing/the-simplest-guide-to-exporting-data-from-autonomous-database-directly-to-object-storage)
THEN:
Let the customer access the Oracle Object Store as they normally would access S3, using Oracle's Amazon S3 Compatibility API. (https://docs.oracle.com/en-us/iaas/Content/Object/Tasks/s3compatibleapi.htm)
OR:
Use an externally driven script to download the data - either from Oracle Object Store or directly from the database - to a server, then push the file up to Amazon S3. The server could be local, or hosted in either Oracle OCI or in AWS, as long as it has access to both object stores. (https://blogs.oracle.com/linux/using-rclone-to-copy-data-in-and-out-of-oracle-cloud-object-storage)
OR:
You may be able to use AWS Data Sync to move data directly from Oracle Object Storage to S3, depending on networking configuration requirements. (https://aws.amazon.com/blogs/aws/aws-datasync-adds-support-for-on-premises-object-storage/)
I have a finished Oracle Apex application which is running in browser. Now I want to build a native Android app and access the data that is stored in the Oracle database.
First I need to authenticate the user with email/password login.
Second I want to send data to Oracle Apex over rest and store it in the database.
Is there a ready-made function of Oracle Apex that allows me to implement these things?
I think it is what you need: https://ruepprich.wordpress.com/2017/07/25/apex-basic-rest-authentication/
Also you can look at this project:

I am creating an offline app,which have a table of data(SQL)..And that data must be in all the phone using my app...The Application must update this table whenever the phone gets connected to Internet.The Users can insert,update but cant delete their data in the table.
I want this table to be in a common place and store the table to Isolated Storage for offline usage .In my search I found that we can do this through OData with SQLAzure in cloud..I do want to know is there any other way of doing it?
You can use sql-ce dabatabase from mango which is stored in IsolatedStorage.
Here is good article.
For online updating I always use custom webservices running on my server, which is not that hard to develop.
Do you have any particular example for MVC3AzureApp which will display Data from the windows azure Table storage. and also CRUD Functionality for the table.
I made a simple Azure project with an MVC3 WebRole with basic CRUD functionality: Download here.
It's not pretty code and I use some bad practice, but this is just meant as an example.
Check "TableStorageController.cs" for all the table manipulation code.
Make sure you have Azure SDK 1.7, or just replace the references with older versions.
Did you get how to perform CRUD on Table Storage?
may be this can help you:

And do you know how to perform Aggregate functions on windows Azure Storage Table too?
