Atom - Jupyter / Hydrogen

Image
I will show you how to use the Atom editor with Jupyter Notebook to debug Python/Django views using Hydrogen plugin. On the Internet you can find some examples using this setup to debug Python but I found nothing related to Django, so I decided to publish this notes. This is not a high performance setup, because it involves many technologies at several layers. This is more a proof of concept of nowadays technologies which are available to the programmer's toolbox. This notes has been written during the development and improvement of the automated tests of the Virtual Library of FAPESP ( http://www.bv.fapesp.br ). The environment The diagram below shows an actual infrastructure to use this setup in a development environment. Technologies It is not expected that you know all of the technologies in detail, but there are some trick points. This paper is oriented for Python programmer who already use Atom and Jupyter and enjoy explore the edges of these tools. ...

ETL, SOLID and Design Patterns

ETL, SOLID and Design Patterns Let's discuss here the best practices to implement a ETL - Extraction Transform Load process using SOLID principles and Design Patterns. Pipeline Pattern One design pattern commonly used in ETL (Extract, Transform, Load) processes is the "Pipeline" pattern. The Pipeline pattern is a software architectural pattern where a series of processing steps are connected together to form a data processing pipeline. Each step in the pipeline performs a specific operation on the data, such as extracting data from a source, transforming it into a desired format, and loading it into a target destination. By using the Pipeline pattern, you can modularize and organize your ETL process into smaller, reusable components. Each component focuses on a specific task, making the overall process more manageable and easier to maintain. Additionally, the Pipeline pattern allows for flexibility and scalability, as you can easily add or remove steps in the pipeli...

Metodologias em ação

Image
O objetivo desse artigo é apresentar algumas metodologias atuais relacionadas à TI, na perspectiva das suas aplicações dentro de uma empresa. A estrutura de cada empresa pode variar muito, dessa maneira irei adotar uma estrutura clássica em formato de pirâmide, representada na figura abaixo para efeitos da nossa análise. As metodologias apresentadas, dificilmente serão utilizadas exatamente como estão sendo estudadas aqui pois não é comum a necessidade de utilizá-las em uma empresa todas ao mesmo tempo, apesar de ser possível. Isso dependerá do tipo de empresa, da estrutura que a mesma possui e como a empresa aplica a TI nos seus negócios. Também será feita uma breve análise do relacionamento entre as diversas metodologias quando adotadas em conjunto. A pirâmide representa a hierarquia em uma empresa tradicional, com o board of directors ficando no topo, abaixo a gerência senior com os CEO, CIO, CSO, CFO etc, abaixo a gerência operacional e abaixo os departamentos operacionais. Qual o ...
