I am creating an android quiz app, the core features of the app are
database user registration and login(registering a minimum of 100k users)
several databases(about 10) for different quiz categories holding about 500k+ questions in total to be retrieved by the user only when there is an internet connection on the android device
i need the app to be really secure as it would also be using credit card information
my question here is which would be better for the database,
using xampp(php, mysql and apache) or using google firebase? and why?
and is having 10 databases for 10 diffrent categories efficient, or can i have one database for the 10 categories?
1st. xampp is fully own your dedicated server, so you will need monitoring
and execute everytime whenever you need to do.Very need time for adding new feature next.
firebase is public server you can use free maintenance and troubleshoot. much feature their offer.push notif,authentification and etc.and it safe and secure for business.for further information you can visit firebase console site,
2nd. 10 database for 10 categories. it mean 1 database for 1 categories. you can call your database based your user request.
conclusion : it depending your technical skill and your exeperience to choosing an online service. if you try develop an app earn money. dont forget put an Ads space. so you can earn money for it.

I developed an Android application for my company to measure the satisfaction of our clients in our stores. I developed the front end with all the screens and the design in Android studio, and I generate the APK for the approval of the directors board. Now I want to develop a dashboard to see results of the application.
Each store has one tablet and the app is already installed. I want to link the answers (Happy - Moderate - Not happy) to a dashboard to show the daily/monthly results.
Honestly I know a little in coding but I'm fast learner if you can show me tutos or books to read quickly .. I heard about something like Back end as service.. is it the right way to begin searching ?
I assume that you want connect your app with the dashboard database. So i am gonna share to you 2 approach.
Approach 1
You can share a database between dashboard and app. If you see the picture you can see that the dashboard presents the data in the screen and the android app Send the anwswer to the database.
Approach 2
If you already has the dashboard with a database, you also can create a table for daily/monthly results and create a service to push the data from the Android app.
For the approach number 1 you can take a look to Firebase Database, and then connect the Dashboard and App to the database.
For the approach number 2 you need to take a look how to create a web service and then update the database with the data received.
I hope it helps you.
I am going to start development of an android application. This will be an online food ordering app. General flow of the app would be that user will first choose a location and based on that client will receive the list of around 300 available restaurants. On selecting a restaurant, client will receive the restaurant menu. Then checkout, payment etc etc. I am giving this info just to give an idea how much and what kind of data app would have.
My question is whether I should use sqlite database for such an app or should develop without it. What are the pros and cons of using a db for such an app. One pros I can think of is that on choosing a different location every time, the restaurants table and the menu table will have to be updated entirely. Not sure if this would be a good idea to use database in this case.
Please suggest.
(A) I have 10 different Suppliers; I sell Hats on their Behalf.
1) 5 of my Suppliers produce hats themselves and sell through other online shops. They rely on traditional methods to manage, so no systems available.
Information has to be manually keyed in through a secure page, which connects to my DB.
2) With my other 5 Suppliers, we have setup an automated feed, so I can directly access their DB/CRM, which is connected directly to my DB.
As a result, I am able to track down any real time data and product availability.
(B) Database, with stored product data.
(C) Output: UI page to display Available hats and product information to Buying Customers.
Issue to figure out…
To help improve customer service and ensure Buying Customers are viewing correct merchandize information:
I need help on figuring out on…
a) How will I be able to ensure information currently held within my DB is kept up-to-date on a frequent basis from 5 of my Suppliers from point A1)…?
As they cannot afford to purchase systems, they are currently manually keying in their information and selling through other online shops. Therefore, making things much more difficult to keep track of.
Please Note:
Need to avoid sending constant emails & Alerts as reminders to update on stock.
Only time they will receive constant emails or alerts, is when a customer has made a purchase or request!
Overall aim is to make sure that a Buying Customer is purchasing stock that is only Available to buy from Suppliers.
What is the best process or solution?
I am planning to create a simple app hotel booking app that will be used by 300-500 users per month. Im looking to use Azure mobile services at its backend service. I have no idea how much I will be using

First come to my mind is I only need
an SQL Database
an Blob Storage
and an API service
Basically im a targeting a minimum viable product so the lower the cost, the better. Does the free account sufficient enought to launch an minimum viable app?
If not can someone estimate for me using

I'm creating an app where user A marks locations on google maps ,those location are stored in a sqlite database on the phone. Now I would like to be able to send those markers to another user where they open up on their map in the app. Now I was just wondering what I would need. I don't want code I just want kind of a checklist. I want this to be free because I have no money right now to rent a server. If I could even use my laptop as a local host just for testing purposes and expand it to a real server later would be ok. A friend said I could use socket.io and node.js and if that's true I will but I need a server / server db to handle everything.
You could try out Amazon SimpleDB:
You can get started with Amazon SimpleDB for free. New and existing
customers receive 25 SimpleDB Machine Hours and 1 GB of Storage for
free each month. Many applications should be able to operate
perpetually within these free tier limits.
