Today there are hundreds of SQL and NoSQL databases. Some of them are popular, some are ignored. Some are user-friendly and well documented and some are hard to use. Some are open-sourced and some are proprietary. And, perhaps, the most important - some are scalable, optimized, highly available and some are difficult to scale or maintain.
There comes the natural question: how to choose a database? To answer it, we should decide, what we want to achieve with a database. To create a view, we should answer questions like these:
When the decision is done, we need to keep in mind, what one or another database able to offer. Particular features of each database may vary, but in general, there are only a few types of databases. Within these types, we can achieve mostly the same goals. Let’s look at them closely.

In SSMS, we many of may noticed System Databases under the Database Folder. But how many of us knows its purpose?. In this article lets discuss about the System Databases in SQL Server.

There are five system databases, these databases are created while installing SQL Server.

virtual environmentfor this project:
# creating pipenv environment for python 3 $ virtualenv venv # activating the pipenv environment $ cd venv/bin #windows environment you activate from Scripts folder # if you have multiple python 3 versions installed then $ source ./activate
SECRET_KEY = #random string DEBUG = #True or False ALLOWED_HOSTS = #localhost DATABASE_NAME = #database name (You can just use the default if you want to use SQLite) DATABASE_USER = #database user for postgres DATABASE_PASSWORD = #database password for postgres DATABASE_HOST = #database host for postgres DATABASE_PORT = #database port for postgres ACCOUNT_EMAIL_VERIFICATION = #mandatory or optional EMAIL_BACKEND = #email backend EMAIL_HOST = #email host EMAIL_HOST_PASSWORD = #email host password EMAIL_USE_TLS = # if your email use tls EMAIL_PORT = #email port

Finding the right database solution for your application is not easy. At iQIYI, one of the largest online video sites in the world, we’re experienced in database selection across several fields: Online Transactional Processing (OLTP), Online Analytical Processing (OLAP), Hybrid Transaction/Analytical Processing (HTAP), SQL, and NoSQL.
Today, I’ll share with you:
I hope this post can help you easily find the right database for your applications.

Frontend developers want interactions with the backends of their web applications to be as painless as possible. Requesting data from the database or making updates to records stored in the database should be simple so that frontend developer can focus on what they do best: creating beautiful and intuitive user interfaces.
GraphQL makes working with databases easy. Rather than relying on backend developers to create specific API endpoints that return pre-selected data fields when querying the database, frontend developers can make simple requests to the backend and retrieve the exact data that they need—no more, no less. This level of flexibility is one reason why GraphQL is so appealing.
Even better, you can use a _hosted _GraphQL backend—Slash GraphQL (by Dgraph). This service is brand new and was publicly released on September 10, 2020. With Slash GraphQL, I can create a new backend endpoint, specify the schema I want for my graph database, and—voila!—be up and running in just a few steps.
The beauty of a hosted backend is that you don’t need to manage your own backend infrastructure, create and manage your own database, or create API endpoints. All of that is taken care of for you.
In this article, we’re going to walk through some of the basic setup for Slash GraphQL and then take a look at how I built a Pokémon Pokédex app with React and Slash GraphQL in just a few hours!
