How to create a client base with access from different devices?

Question

Database

there is a Customer Base (phone book in iPhone). Each client has his own client history (the number of successful orders, cancellations, and ordered and disappeared). To make it easier to understand, imagine a taxi service.
And now we want to distribute our database to drivers. But in order to preserve the confidentiality of customers, there are two ways here:
First option , Simplified:
the driver must enter at least 5-6 digits of the phone number, and if it matches with the numbers that we have, the program should show the appropriate results.
Also, the driver should be able to leave his assessment of this number. Evaluation criteria 4 pieces.
1 confirmed (there was an order and everything went well)
2 cancellation (there was an order, the client measured later, but in advance)
3 cancellation in 5 minutes (measured but 5 minutes before the appointed time, at the last moment)
4 prodynamil (ordered then stopped responding)
And some small field for the driver's notes. Even two, one for comments so that other drivers can read this comment. And the second for myself.
The second option is more desirable but it is more complicated.
The same Base, only each client is assigned his own personal ID number when we add it manually and then later on his client history. When calling or receiving an SMS or WhatsApp call or message, if this number is in our database, so that the driver would only see his and her ID in our system and his customer history, but not see the phone number.
There should be many more different functions in this program, I will not list them all now. If there is a person who had a good similar experience with a similar program and thoroughly understands it and can do it for us, we are ready to discuss it as a separate work.
Just before that, we tried to lay it out in search of a programmer who can do it for us. It turned out that there are many similar ready-made solutions. Therefore, I would first like to see the opinions of competent people and links to something similar, perhaps as similar as possible, which then can simply be finalized for us.
Here is something similar offered by twilio https://www.twilio.com/console/sms/add-ons
There are also many similar things on www.wolfram.com
Но мой инглиш не насколько богат что бы осилить все это... спасибо за советы.
Или покажите что то пожее, буду благодарен любому опыту и совету.

Answer 1

Нужен сервер с базой/базами данных (водителей, клиентов и пр.), который будет обрабатывать входящие запросы. Как организовать передачу информации в обе стороны - это вопрос творческий: можно написать отдельное клиентское приложение для водителей, а можно использовать, например, вайбер-бота (водитель будет получать заказ и отправлять сообщения с отзывом на определенный номер).
С технической точки зрения это не очень сложная задача. Программист со знанием БД и сисадминскими навыками вам такое напишет. Это даже может быть решением в облаке, что гораздо дешевле физического сервака с его обслуживанием.
Другой вопрос, насколько это будет выгодно и скорее всего, вам дешевле будет взять готовое решение с индивидуальными правками (обычно разработчики такое делают).
