10 Jul 2019
What kind of data model makes online concert ticketing work?

Online shops let us buy tickets to concerts by our favorite artists without leaving our comfortable homes. We can find a venue or a location (even one that’s not near us), choose a seat, and get our tickets delivered instantly through email – or maybe we’ll wait several days and get the tickets delivered.

Using Python and MySQL in the ETL Process: Using Python and SQLAlchemy
26 Jun 2019
In the previous two articles of this series, we discussed how to use Python and SQLAlchemy to perform the ETL process. Today we’ll do the same, but this time using Python and SQL Alchemy without SQL commands in textual format. This will enable us to use SQLAlchemy regardless of the database engine we’re connected to. So, let’s start. Today we’ll discuss how to perform the ETL process using Python and SQLAlchemy.

Using Python and MySQL in the ETL Process: SQLAlchemy
12 Jun 2019
SQLAlchemy helps you work with databases in Python. In this post, we tell you everything you need to know to get started with this module.
In the previous article, we talked about how to use Python in the ETL process. We focused on getting the job done by executing stored procedures and SQL queries. In this article and the next, we’ll use a different approach. Instead of writing SQL code, we’ll use the SQLAlchemy toolkit.

Using Python and MySQL in the ETL Process
22 May 2019
Python is very popular these days. Since Python is a general-purpose programming language, it can also be used to perform the Extract, Transform, Load (ETL) process. Different ETL modules are available, but today we’ll stick with the combination of Python and MySQL. We’ll use Python to invoke stored procedures and prepare and execute SQL statements. We’ll use two similar-but-different approaches. First, we’ll invoke stored procedures that will do the whole job, and after that we’ll analyze how we could do the same process without stored procedures by using MySQL code in Python.

The Important Dates Data Model
3 Apr 2019
Are you forgetting something? A data model to help you remember important dates – before they happen. Have you ever forgotten an important date – your mom’s birthday or your anniversary? Or that you’re giving a lecture? Yup, things like that happen in real life. Maybe not to all of us, but to some of us (including me), they certainly do. To prevent such disasters, we’ll create a data model you could use as the background for an application that will notify you right on time.

A Data Model for an Online Musical Equipment Shop
20 Mar 2019
What kind of data model supports an online musical equipment store?Musical equipment shops used to be one of those old-fashioned industries, one that you wouldn’t expect could (or should) adapt to the online world. It wasn’t unreasonable to paint such a picture. After all, you can’t choose your ideal guitar based solely on magazine pictures, can you? Musicians and wannabe-musicians need to try various instruments, hearing and feeling how each one responds when played.
