I am using c# windows form application.I need to store some Images later on will use them in application.
Is it good to store images locally on drive and use jSon file with key,value,path.
or to store the images in Database.

I'm currently thinking of a concept for a react-native app where people add events over a period of time like a diary/log. These events need to be exported and for security and privacy reasons I don't want to use a database. I've read you can use JSON files as a storage method, too.
How can I store data from the app to a JSON file and load the data from the JSON file back in the app? Don't need any code, helpful articles or webpages are appreciated
Assuming that you already have all the app data into a json, its rather simple.
Decide where to store the appdata.json, lets call it APP_DATA_PATH
Find a library to read/write files (I've only used expo-file-system)
On app boot, check if APP_DATA_PATH exists, if it does read the file and load into app, if not assume its a new user
Whenever app data changes, write the changes to APP_DATA_PATH
I'm trying to make a centralized POS system, was wondering what are my options to save data locally to the device to save data connection rather than making the POS online-only app.
I already have the APIs from Laravel being pulled into JSON and basically need to find a way to store data, as well as to convert image_location into blob or something Flutter can do, (is Image.memory viable?). The APIs will only be triggered on app startup if the device is connected to the internet.
You can use a plugin called sqflite which works for ios and android.
and also SharedPreference plugin which stores data in key-value format.
you can search for plugins and there example on https://pub.dev/
I want to synchronize data from a nosql database, have it emit json, and when there is a change and the app is online, have the app pull the changes and update them.
My react-native app uses a few language-specific json files loading them dynamically into javascript objects and then using them as my "database". One file for rendering content, one for the app texts, and one for the styles.
When the user changes the language a different directory is used with the same set of json filenames. This is done via the index.js in that directory and loaded into redux.
Must I change the way my app works, and use a NoSQL/real database directly in the app? So that I can use a solution like this one: synchronizing pouchDB with json data
(that solution is for working if I understand correctly in the exact opposite direction. The app is working with a database and synchronizing with json received from the web)
Or can I update the data in an external (preferably) NoSQL (pouchDB or couchDB) or relational database, and somehow "synchronize" it with the json files, when the app is connected to the web and have it update?
Is there a known method or framework to accomplish this with react-native?
I have a number of different types of files stored in a MySQL database (varbinaryMAX). I am in the process of building a document management system and my final phase is to install some sort of document viewer so that these files can be prievewed.
I have veered away from Google Docs due to the security of the documents. I have [preliminarily] settled with Viewer.JS as my chosen method of preview as it supports a wide variety of filetypes, and is free. It does however require a directly accessible URL for the file, which I of course dont have as the file is sitting in a coloumn in the DB.
How would I go about generating a URL that can be used to access a/the file in the DB?
Application is ASP.net
I am trying to build an Employement Management App in AngularJS where a basic operation is adding an employee.
I am displaying details using a service and getting Json data from the mock json file i am using.
Similarly, can i add form data to a textfile on the harddisk.
I have seen it done in a tutorial using $resource.save.
If at all it is possible without any server side code please share the example,it would be helpful.
Thanks.
You can make use of HTML5 local browser storage, as this does not require folder access. Mode datails here http://diveintohtml5.info/storage.html
AngularJS has modules for local storage which you can use to access such storages like this https://github.com/grevory/angular-local-storage
