I know how to create a table in Google Big Table. But with my constraints I want to create database and store all the tables inside that database.
Start with the Getting Started documentation for Java or Python. The App Engine environment provides your app with a connection to a single datastore instance - you can't create new datastores for your app, so you'll need to partition your data yourself, inside the datastore.
The datastore also doesn't use 'tables' as you may be used to with a relational database, but instead uses 'entity types' to break data up similarly to tables. The documentation has more information on how it all works.

I am using Google Sheets to create a database that is connected to Google Data Studio. But the database is growing fast and will soon overgrow Sheets limits.
I am looking for a cloud service that is simple to use like Sheets, where I can manually add data, do calculations (like formulas in Sheets) and also use Python to update the data there. I also need it to connect to Google Data Studio for visualisation.
I got recommended Firestore, Cloud SQL, Bigquery, but I still do not understand the difference between them. I am looking for something cheap where I can do the things I mentioned above.
P.S. I am new to SQL, so I would prefer a visual database (like Sheets).
Thank you all!
Sheet is not a database, but you can use as is. You have other type of database on Google Cloud, such as
Firestore a document oriented database, not really similar to a tabular Sheet
BigQuery which is a datawarehouse very powerful and the most similar to sheet in its design, checks and controls
Cloud SQL hosts relational database engine, similar to BigQuery but with, in addition, the capacity to create contraint (unique value, primary key, external (foreign) key in relation with another value in another table.
However, no one offer the easiness of Sheet in term of graphical interface. The engine are powerful but are developer oriented and not desktop user oriented.
I made a Spotify app that analyzes user data and manages interactive features by writing the API responses to a PostgreSQL database. The developer rules state that basically I have to delete the data when the user is not actively using my app.
Is there a way to automate this on the server (I'm using AWS Lightsail/Ubuntu) to do it daily? Would I need to add a datetime column to all of my tables and follow one of these: https://www.the-art-of-web.com/sql/trigger-delete-old/? Or is there a better way?
I'm using Azure Mobile App service for the first time. I have an existing database which is hosted by Azure. I used this database when creating the App service. I followed this tutorial here which demonstrates how to use existing database. I first created the schema with the same name as the App service and then transferred all tables to that schema. Now I'm trying to access these tables from the Azure portal. I went to Easy Tables tab and created the tables with the same name as in my database and when I click into the table, I don't see any records that are already in the database. The new table that was created, doesn't have the same fields as the tables in my database. They have the following fields : "ID", "CREATEDAT", "UPDATEDAT", "VERSION", "DELETED". The tutorial I followed seemed to have worked for many people. I have the primary keys in my tables with the name "id".
Can anyone give me an idea what the problem might be?
The problem is that you followed a tutorial meant for Azure Mobile Services and applied it to Azure App Service - these are two totally different things. Probably most importantly, your tables are not in the [dbo] schema, which is where Easy Tables expects them to be (unless you configure the app service otherwise). In addition, Mobile Services used double-underscore before the system properties, whereas App Service does not.
If you want to use your existing database, follow the instructions in my App Service Mobile Apps tutorial here: https://shellmonger.com/2016/05/11/30-days-of-zumo-v2-azure-mobile-apps-day-19-asp-net-table-controllers/
I would like to build an application that serve a lot of users, so I decide to use cloud datastore because it is more scalable, but i also want to have an interface that will help me observe my data with some complex sql query.
so i decide to build my data with tow data base (cloud data store and cloud sql) and the users for my application will get the data from the datastore, and me with my interface i will use cloud sql.
The users will just read data they will not write to the datastore, but me with my interface I would read the data from my cloud sql so i can use complex query, and if i want to write or change the data, I will change both data in cloud sql and data sore.
what do you think? is there another suggestion ? thank you
I created one project.i want to use google Big table as my database.
so that i used JPA datastore.I created one JPA program(using eclipse) in that i selected ODBC database.I display lot of option like MySQL etc.. What option i select to interact with Bigtable.
Yes, you an use JPA with App Engine's data store. There is no connection to MySQL.
