If there is a spike of traffic, AWS would start up more lambdas, each of them having their own local copy of sqllite. Perfectly horizontally scaleable. There would be another process that runs by cron, that creates the mysqldb and stores in S3. That might copy from postgresql

How to Defend Against SQL Injection Attacks 1. Use Prepared Statements (Parameterized Queries) The most effective defense against SQL injection is to use prepared statements with parameterized queries. Example in Python with MySQL (using MySQLdb library):

mysqlDBをなぜかローカルで作成してから繋げようとして、沼って全然進まない日々が続いた。AWSで作ればいいじゃん... 今週はRDS作ってデータ入れ込んでフロントに表示させるまでやる。

Alang2 company ade vacancy utk backend developer. Mari sini sorang backend developer apply company aku haha. -at least 1 year experience -ada experience python(flask)/php(laravel) - tahu handle mysqldb -experience dgn aws environment

俺の中では、mysqlDB一択だけどな。 マルチテナントのDBアクセスは、逆にデータが他の会社と混ざらないようにするのにDBの機能がないと安心できないんかという気持ちになる。

Day 3 of #100DaysofALXSE Today, I've learned to use the MySQLdb module which helps execute SQL queries using Python. #ALX_SE

Day 9 of #100DaysOfALXSE and I am still on that mysqldb and SQLalchemy thing, I think I am starting to get it. #DoHardThings

Having issues with mysql, mysqldb and sqlalchemy. The environment is activated(python) and the packages are installed but i keep getting 'cannot find module' for both when i run. Ho where are my packages

#Day37 - #Day38 Back into some backend with python, Getting to know ORM(object relational mapping) helps to work with classes instead of raw SQL queries. ✅ Learned how to use MySQLdb for db management in python -> Learning how to use sqlalchemy in my .py code #100DaysOfALXSE

Day 27 and 28 of #100daysofALXSE I am currently working on the Python ORM Alx project. I am learning about the MySQLdb Python database API and also learning about SQLAlchemy, which is a Python ORM tool. #100daysofALXSE #ALX_SE #DoHardThings

Day 39 of #100DaysOfALXSE Object Relational mapping. An easier way to interact with relational databases without writing SQL queries. Tackled Python Mysqldb too and how to work with it. #SQLAlchemy #pythonprogramming #Relationaldatabases @facesofalxse

alright, I did a few fix to the app and now it works just as expected. Every 10 seconds, it saves data to the database. I noticed that mysqldb module was deprecated that's why I had the error earlier.

#Day34 of #100DaysOfALXSE --Deep dive into more Object-relational Mapping, work more on python SQLAlchemy. --MySQLdb. --Glad to discover python virtual Environments . It's safer to work within it .

#Days 6-7 of #100DaysOfALXSE Deep dive into SQLAlchemy these 2 days! Engines, mapping, sessions - the whole workflow conquered! Feeling confident! Practiced secure interactions with mysqldb in my local Python env too. #ALX_SE #DoHardThings
