Everthing work for me (Cloud firestore and Firebase Database)
May be you have no data there so it is showing the create new database page. Type https://console.firebase.google.com/u/2/project/yourProjectId/database/yourProjectId/data on the search bar, and you will be there. Don't forget to replace yourProjectId with your project ID.

I made a complete app using firebase, expo and react native (with login screen and other features). But it didn't work as I expected because I need an app that the database works offline (I want the user to use the app offline, and then connect to the internet and "update" the data).
In other words, I'm looking for another way. I heard about Realm, but it doesn't work with Expo (from what I've researched). Can anyone guide me to some possibilities??
About the app I'm making: login>selection>release
*the user logs in (offline. The first time can be online, but when entering the app again, the login must be OFFLINE). The next screen is 'selection' (all screens show information of the logged in user), the user writes some information that is saved in a database. When completing the 'selection', the next screen is 'release', in which the user will add information in the same data table (db) before (from the 'selection' screen). The user will not have internet when entering the app (but he can access the internet later and update his data as soon as he connects).
Firebase work offline and import the data when it is online.
Now about the other db that works with expo, if you like working with SQL then there is something I built expo-sqlite-wrapper it is a good ORM and did not find any better.
There is also a JSON based database easy-db-react-native, the downside of this is that you can't have too much data saved.
Okay so I’m need guidance on where to start.
What I want to do is upon clicking a button in my web app which will be labelled “search” the web app will connect to my realism database and search the data base for the “search criteria” and the once found all matching cases it will create div blocks with the information inside it, in a list view and assign the ID of the div to the UID it gets back from the database.
database:
Users
--> Country
---->State
----->City
------>Post/ZipCode
------->UID
--------> Users informantion
Welcome to StackOverflow!
A great place to get started is the Firebase Realtime Database doocumentation or searching for Firecasts on YouTube (linked below).
As requested, here are some questions to ask yourself to get started and help scope out and define your new Firebase project.
What language are you going to use?
Are you planning on using any frameworks/libraries? e.g. For Javascript, these would include things like jQuery, Polymer, and React
What information are you storing in your database? e.g. user profiles, private user data/settings, public indexes, username lists, etc.
How is your database structured?
What data is being searched? The entire database? Values in a certain location?
What data needs to be displayed in your view?
Is the data accessible for just the current user or is it a public database that anyone can use?
What search criteria will be used? Is it just one filter at a time or many?
The answers to these questions aren't set in stone, but are to help you start thinking about the future of your project. They can be changed at any time as this isn't SQL where everything has to have its own schema.
If you intend on using "advanced searches" where you'll filter by multiple parameters at the same time, consider using Cloud Firestore instead.
I recommend looking at some Firecasts to help guide you through these questions. Here are some links to them:

Hi I have a question about wordpress.
How does wordpress templates retrieve or fetch data from database? They must be having some query which I am not able to figure out. I want to create a new column to the database for ex, wp_data and fetch that column with the help of the function and display it. So I want to know how the template actually fetches data from database so that I can do the same. I tried contacting the support team of the template owners, but they replied saying they would provide the service only to the Pro version users. Please help me while I am stuck with this.
Thanks in advance
If you want to fetch data from the database without using inbuilt functions go through with this link interacting with the wordpress database
Before you starts with wordpress read the document from its official site wordpress documentation which will help you how wordpress works.
I'm building a Laravel website and I'm using the database driver to manage sessions. I created the sessions table in database and migrated with php artisan. Everything works as expected.
What I really want to do now is to check the role of the users that are online but I don't know how to get this with the fields of the sessions table in the database.
I don't really understand how the sessions table work, because I see that it registers a new row when I access to the login page, but it doesn't change when the user has logged in and when the user has logged out.
All I wanted is to check the role of the users active in the app....
Someone can help me with how to get to this?
Thank you!
I suggest you a very simple way. Just in your users table add a field called "is_online" that is 0 by default. When the user logs in , just change it to 1 and when he logs out change it back to 0. So DB::table('users')->where('is_online' , 1)->all() returns the online users.
I'm using Django with sqlite to make a web app and ran into a little issue.
I created a table under models file called deletedOrder, gave it variables etc., and then ran manage.py syncdb. This created the table in my database and I was able to add data to the database table and read the data back out, however this added table is not showing up on the Django admin interface.
Is there something else that I have to do to get this to be in the admin page?
You need to register your models to make them show up in the admin as documented here.
