I am new to mobile application development. I am preparing an application in React Native. In my application, 1000 words and 1000 sentences about these words will be in 2 languages. There will also be a picture for each word. By pressing the button in the application, the user will see the words, sentences in both languages and the picture of the word. Which database in firebase makes the application run faster? Firestore Database or Realtime Database?

We are researching at using Expo to build an offline first app that requires medium storage and encryption.
It is an app comprising of several user filled forms and data tables.
The core requirements are:
Offline ability. Allowing the user to fill in several forms whilst offline and have the device push this data via POST requests when the device receives a connection.
So far we have a basic working offline app that utilises redux offline (https://github.com/redux-offline/redux-offline) to store client actions when the device is offline and automatically sync this when the device receives a connection.
Store a medium amount of JSON data (100MB+) for offline usage. The app needs to grab this data from a GET request and store it locally. The JSON data is used as part of the form journeys, allowing the user to select from predefined dropdown fields, etc.
We are unsure how to approach this with Expo.
All the stored data must be encrypted.
We are unsure how to approach this with Expo.
Authentication via Keycloak.
This is proving difficult due to the lack of documentation on Expo. It seems it should be done via AuthSession (https://docs.expo.dev/versions/latest/sdk/auth-session/).
The storage and encryption requirements are proving particularly difficult to work around. Are these possible with Expo? Or would we need to eject for React Native for these? Any advice would be much appreciated. Thanks
I am new to app development and I am thinking about creating an app which will store all the anime that you are currently watching or have watched in the past. The purpose of this app is to store your progress of an anime/manga so that if you forget which chapter you were on the last time you watched/read the anime or manga.
My plan is to connect this app to myanimelist website and use its feature on my app to find an anime. Then if the user adds the anime to his watch-list then it will store the important data e.g., name, description, author, Image.
I am totally new to app development and I have to create an app for the final year project. As on how to start the app or the resources required I am at loss.
The main topic of my concern is on how I should handle the use of website data or the connection to the database. Is something like using SQL queries? Which database should I use to store the data on local device?
Any help is appreciated.
Your questions
how I should handle the use of website data or the connection to the database.
if You have an API that you are using for your website, then you can use that API to fetch data in your flutter app.In case your don't have an API you have to create one for your app.
Which database should I use to store the data on the local device?
For storing data to the local device you can use sqflite package for flutter to store data. Using sqflite you can write simple SQL queries to fetch or store data in the
database.
Ask if you have any problems.
The AUT is a web application. There are different types of users like admint, consumer etc.
The application is a utility domain application. There is hardly any data that user/human inputs into the system.
The data is coming from electronic meters and getting stored in the database.
Our application only renders the data to the consumers, admins and other users with the data with different calculations in the form of charts and graphs.
There are about 9-10 pages in the application.
My question is : How can I proceed with automation in this scenario..?
Our company is thinking about a mobile app (android, ios) that needs to comunicate with a backend sending "questions" and receiving "answers", based on a search in an ontology database.
I have some questions:
1)What is the state of the art in ontology database at the moment (both commercial or open source)?
2)In order to develop such a backend, what kind of server(software) is required?
3)Since this application is supposed to have thousands of users at a time (it is meant for public administration purposes), what kind of server (hardware) would be require? (distribuited server, load balanced, etc).
Thank you very much.
I'd like to develop a small Facebook game with some graphics involved (not that many). Within that game, the users will be able to buy/sell certain items and I wonder WHERE I can save those items/virtual money ...? Does Facebook offer me a database I can use?
You will need to host your own database for your game. Facebook just provides the frontend, it's up to you to manage and run the backend services.
