Editing shapefile in a webapp

I need to develop a web application to make users edit a shapefile in the browser.
Main idea would be to load a shapefile with his layers, and then let users create lines, polylines and so, saving that data to the shapefile.
An improvememt would be to save data to db.
I searched on the Internet but I can't find a opensource solution.
I took a look at lizmap and qgis server but It seems there Is not the possibility to insert vectorial items or edit the Ones already present.
Can someone help? Thanks in advance
What you are looking for can be achieved by using GeoServer and a WFS-T client such as OpenLayers. See for example this tutorial or this question for examples.

Using AngularJS with Oracle Apex

I was wondering if anyone who uses AngularJS with Oracle Apex could recommend some resources or tutorials on integrating the two please?
I have found a Dan McGhan presentation and a Codersaurus video but unfortunately these don't go into sufficient detail to start me off.
Any help or advice would be gratefully received. Thanks in advance.
A quick Google search gave me this Guide from Dan McGhan. In part 3 he shows a nice way how to embed the neccessary files, even that you will need to take care of the allow-file-access-from-files property.

Android answer database

I am pretty new in this game so please do not judge me harshly.
So I need to build a question/answer database for an app.
The idea is simple:
User types a question and if I have an answer in my database, it gives an answer. If I do not have an answer, it goes for my manual moderation, so I can add new answers for the future.
I do not know if someone has already build a software like this and I can just buy one, or do I have to hire someone to build one from the ground. Which language should I use? Which software?
I know that Java, C++ and SQL are most popular languages for that type of jobs, but are they the best solution or there are better languages?
I need a database that can hold a really huge amount of data.
I would really appreciate any help guys!
and if any of you can build me this database, I do not mind to hire a freelancer.
Thank you!
Best Regards,
Ayazhan.
Yes you can do it.
if you have some knowledge in SQl then you can make an local Db in your app and consume it according to requirement. The simple question and answer app contains set of predefined questions.
