I have a database in SQLite format in my local HD. I would like to get the database up to GAE so that I can use it to create certain cool web-apps. I have browsed around for a way to do it. However, mostly the projects available are to backup the database in GAE to my local HD. Is there an existing way to get the local Sqlite db up to GAE already?
There is no way that you can do it directly on appengine, as writing to a file is restricted in appengine . I would say, you should export your sqlite database file to some common format like csv , design the model similar to sqlite table schema. Then write a script to load all those sqlite records into dev_sever (development env included in sdk), Then you can easily upload the data from local developement server to google appengine. Have a look at this to know how to export development server data to appengine.
You can do this with the Google Cloud Storage service (https://developers.google.com/storage/). Your application can read write to files stored in the Google cloud storage, so it is possible to put sqlite files there and read from and write to them.

I have one Storage Account on Azure where I get lots of json files from somewhere. I am running an exe on my computer constantly to get the Json File and read the data from json and convert the data into table and upload it on an SQL Server database on azure - A synchronization process
I have not worked with WebJob or FunctionApp
I believe this can be done by FunctionApp triggering on blob. I am not sure if I will be able to do the complete process as I do locally on FunctionApp.
Is this the right decision for this purpose or would you suggest WebJob for this?
If you prefer to use azure web jobs, this should be as simple as just uploading a .zip file of your project. You can follow this article to create the webjob, and the webjob should work as what you do locally.
If you prefer to use azure function, then you can use blob trigger do the same thing, but you may make some changes as per your need.
Is there any way that I can accomplish the functionality of File Tables, in Azure SQL Database?
I know the File Tables functionality is not included in SQL Database Azure, so a way to accomplish these functionality?
I intend to save PDF files, and it can be larger than 20 Mb, and it will be a lot, so I am thinking a way to solve these...
any suggestions??
One Azure solution for file storage is Azure Blob Storage.
Azure Blob storage is a service that stores unstructured data in the cloud as objects/blobs. Blob storage can store any type of text or binary data, such as a document, media file, or application installer. Blob storage is also referred to as object storage.
Common uses of Blob storage include:
Serving images or documents directly to a browser
Storing files for distributed access
Streaming video and audio Storing data for backup and restore, disaster recovery, and archiving
Storing data for analysis by an on-premises or Azure-hosted service
It has RESTful API as well as some SDK for all popular languages that will help you manage your blob files in Azure.

I am working on a phonegap project to build a cross platform mobile app, and came to know from a website that the app's database can be deployed/built with "database.com".
The procedure is well explained but I have one question -
how to sync the database available on database.com with a database on a local server?
i.e. for e.g., if a client has his database (of his desktop application) on his local server and he requires a mobile app of the same now, what is the procedure to be followed in "database.com" to sync his server's database with the database on "database.com"?
PS: I need to use "database.com" for my database because I want to maintain it on cloud, and I do not have capability to maintain a local server.
You might need a service for data syncing if it is to be more than once. I work on a project that does exactly this.

Otherwise, model your tables to Salesforce Custom Objects, export the data on the local server to CVS and use the Data Loader to import.
I'm trying to make a facebook application that stores some user data in a database. What kind of databases can I use if I'm using Heroku? Can I use SQLite?
SQLite is the one database you can't use.
Heroku will give you a 5Mb Postgres database for free with your application (assuming it's a rails application). There are addon providers for mySQL, Redis etc or you're free to connect to you own database outside of Heroku but beware of the latency that you will experience.
I am trying to get my local sqlite db up and running on GAE. According to this post, there is no way for me to get my local db up there directly. That's why I would like to do something like this:
I get the sqlite db up and running on my dev server with this: http://code.google.com/p/gae-sqlite/
Locally, I translate the db scheme into django model and migrate the db into GAE db.
I use google's way to get my data up to GAE.
So here comes my question. Is there any project that is able to directly translate sqlite db scheme into django model directly?
If not, I guess I will have to write up a code gen.
Thanks
gae-sqlite (now superceded by built-in sqlite support) is designed to run the development appserver backend on sqlite for speed and reduced memory consumption. It doesn't let you import or use your own sqlite schema in App Engine.
You need to dump your data to CSV files, and use the App Engine bulkloader (which you linked to) to bulkload them into the dev_appserver and production environments. Alternately, it is possible to bulkload direct from the sqlite database, but that's a lot more involved, and probably not worth the effort.
