Databases Are Forever

Today is a big episode. We’re adding database support to our application. Which means that we’ll be able to store data…forever! Cuz it’s a database! And it can store things!

We’re using MongoDB as our database of choice so get yourself ready to have our data…live forever.

Disclaimer: I work for MongoDB but I am not speaking for MongoDB in this video.

System Databases in SQL Server

Introduction

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.

System Database

Fig. 1 System Databases

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

Master
Model
MSDB
Tempdb
Resource

Master

This database contains all the System level Information in SQL Server. The Information in form of Meta data.
Because of this master database, we are able to access the SQL Server (On premise SQL Server)

Model

This database is used as a template for new databases.
Whenever a new database is created, initially a copy of model database is what created as new database.

MSDB

This database is where a service called SQL Server Agent stores its data.
SQL server Agent is in charge of automation, which includes entities such as jobs, schedules, and alerts.

TempDB

The Tempdb is where SQL Server stores temporary data such as work tables, sort space, row versioning information and etc.
User can create their own version of temporary tables and those are stored in Tempdb.
But this database is destroyed and recreated every time when we restart the instance of SQL Server.

Resource

The resource database is a hidden, read only database that holds the definitions of all system objects.
When we query system object in a database, they appear to reside in the sys schema of the local database, but in actually their definitions reside in the resource db.

How to Efficiently Choose the Right Database for Your Applications

Finding the right database solution for your application is not easy. Learn how to efficiently find a database for your applications.

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:

What criteria to use for selecting a database.
What databases we use at iQIYI.
Some decision models to help you efficiently pick a database.
Tips for choosing your database.

I hope this post can help you easily find the right database for your applications.

What is SQL? And Where is it Used?

Define: SQL [pron. “sequel”] – stands for Structured Query Language (SQL), used by databases to model and manage tabular/relational datasets; a set of standardized Data Definition Language (DDL) functions to create tables, views, and define relational schema models, and Data Manipulation Language (DML) to query, insert, and modify data in the tables.

*Read-only select queries are technically part of its Data Query Language (DQL) group. Still, operationally, many refer to it as DML because it can do more than read-only queries.

How to Build a Pokedex React App with a Slash GraphQL Backend

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!
