Any one has done this, i want to get data parse from the JSON (Google location API) and store it into the sqlite databse on the iphone.
Problem is that if the parsed data is huge in amount how to synchronize the parsing and saving data in sqlite locally on the iphone.
And user interface includes table of saved data that should be work with out any interruption.
And the solution should be in COCOA Framework using Objective C
You must read some tutorials

I'm building an architecture using boto3, and I hope to dump the data in JSON format from API to S3. What blocks in my way right now is first, firehose does NOT support JSON; my workaround right now is not compressing them but it's still different from a JSON file. But I still want to see a better choice to make the files more compatible.
And second, the file names can't be customized. All the data I collected will be eventually converted onto Athena for the query, so can boto3 do the naming?
Answering a couple of the questions you have. Firstly if you stream JSON into Firehose it will write JSON to S3. JSON is the file data structure and compression is the file type. Compressing JSON doesn't make it something else. You'll just need to decompress it before consuming it.
RE: file naming, you shouldn't care about that. Let the system name it whatever. If you define the Athena table with the location, you'll be able to query it. When new files are added, you'll be able to query them immediately.
Here is an AWS tutorial that walks you through this process. JSON stream to S3 with Athena query.
i want to handle a requirement in polymer webcomponents where user can upload csv file from ui and csv file can be parsed to json and sent to server ,i searched and found for vaadin upload,looked over the api but i am not sure how to receive the csv file and convert to json and sent to server,can anyone show a jsfiddle of vaadin upload or any other web component to handle this scenario?
First of all, I am wondering why you would not simply do the conversion on the server side.
In this case, you would be able to use the vaadin-upload directly indeed.
Here is a snippet that would upload all files to the example.com server, and only allow CSV files.
<vaadin-upload target="https://example.com/upload" method="POST" accept="text/csv">
</vaadin-upload>
There are plenty of resources on how to convert CSV files to JSON.
Here is a snippet
And here is a node library
If you really wanted to do the conversion client side, then I would suggest to create an element that would embed a vaadin-upload, and convert the Files array to Json before manually calling the uploadFiles method.
As Azure blob storage is a very cheap data storage solution, would it make sense to store JSON data in blobs so clients can access it like a data API? This way we don't need to spin up Web Apps/APIs to server JSON data.
That could work, depending on the scenario. The blobs will be updated on-the-fly when you push a new version of the JSON files.
I demonstrated this a while ago with a simple app that uploads and updates a file. Clients could target the URL and for them is seemed like they were accessing a JSON data feed that kept being updated.
We have sqLite Table.Now We converted db data into JSON Object.We need JSON data save to my mobile Sd_Card.Any file like .txt or excel or word any type of format not problem.
We need JSON data Save to Local phone-memory or SD-Card.guide me how to save.First Tell me it's possible or not
Well, all you are asking is if it is possible, so that's easy, yes. You said "phone memory" or SD-Card. I assume you mean persistent memory, like with WebSQL. Since JSON is just a string, you can insert it into a WebSQL table just fine. You could also, more easier, store it in LocalStorage. Finally, if you want to use the file system, that's simple too, just be sure to add the File plugin.
I have JSON data which has say three levels of nesting.I need to support localization of my app.I can find resources on how to create res file and support multiple languages,But they all seem to be for a single string.How do I place my nested JSON data in res file??
There are two simple ways to solve the problem that may work for you:
Depending on the size of the JSON file, you can just store the stringified JSON data as a string resource. For small amounts of data, it's a simple solution.
For larger files, I'd suggest instead that you store a file name/path which points at the corresponding JSON file that is appropriate for the current locale. You'd just load the file based on the file name provided in the resource at run time.
