Over the last two decades organizations have widely used the data generated from internal and external sources to derive intelligence that would help them grow and gain competitive advantages. According to the 2013 technology report by Gartner, ‘Business Intelligence & Analytics’ is the number one priority for CIOs to address. Yet many organizations are struggling to implement Read More →

Effective integration of testing in the implementation process builds trust and confidence among business users as they make crucial strategic decisions, based on the BI data generated.
Testing of Data Warehouse/Business Intelligence (DW/BI) applications is a little different than testing traditional transactional applications as it requires data-centric testing approach.
The typical challenges an enterprises faces while testing Read More →

Définition du KPI
Il s'agit d'un acronyme de Key Performance Indicator, ce qui signifie en français : Indicateur de performance clé.
Ce sont des mesures qui permettent aux entreprises d'évaluer la performance d'un domaine. On parle aussi de "metrics", même si une différence existe entre ces 2 termes :

les KPIs sont liés à un objectif Read More →

À l'informatique
Von Neumann a donné son nom à l'architecture de von Neumann utilisée dans la quasi-totalité des ordinateurs modernes, l'apport d'autres collaborateurs de l'EDVAC en est par conséquent grandement minimisé (on citera J. Presper Eckert et John William Mauchly parmi d'autres). Cela est dû au fait qu'il est, en 1945, le rapporteur des travaux pionniers Read More →

An algorithm is little more than a series of steps required to perform some task. If we treat each step as a basic unit of computation, then an algorithm’s execution time can be expressed as the number of steps required to solve the problem.
This abstraction is exactly what we need: it characterizes an algorithm’s efficiency Read More →

Data warehousing provides decision-support data that is consistent, integrated, standard, and simply understood.
What Is Data Warehousing ?
Data warehousing is a process for collecting, storing, and delivering decision-support data for some or all of an enterprise. Data warehousing is a broad subject that is described point-by-point in this Refcard. A data warehouse is one of the Read More →

This book is a practical—and, we hope, entertaining—introduction to some of the most important algorithms and data structures in computer science.
We know that some software engineers think “practical algorithms” is an oxymoron 😞 so we’ve done our best to keep this book brief, useful and approachable.1 The code samples are in idiomatic Python, and the Read More →
