    With storytelling and lots of examples, Doug “The Data Guy” Needham explains the math that creates the foundation for efficient databases, flexible data interchange formats, and robust applications. Data modeling, SQL, and relational database design are covered in detail using global standards as well as many examples in Snowflake. Also covered are dimensional modeling, JSON, XML, data vault, and graph databases.

    The math you will learn and be able to apply includes set theory, logic (implicational, conditional, prepositional, and first order predicate), functions, relational algebra and calculus, graph theory, and combinatorics.

    There is foundational knowledge required to excel in any discipline. Accountants must know double-entry bookkeeping, doctors must know basic human anatomy, car mechanics must know engine mechanics, and data professionals must know the math behind their profession. This book provides the fundamental knowledge needed to appreciate and excel in data management.

    You do not need to be a mathematician (or even like math!) to master the formulas and techniques within these pages that will prepare you for building robust data structures and queries.

    Imagine a Graph designed to leverage an organizations Meta Data that can guide you in making decisions on how best to organize your infrastructure, or even be able to anticipate poorly performing queries. A Data Structure Graph is a group of atomic entities that are related to each other, stored in a repository, then moved from one persistence layer to another, rendered as a Graph. This graph can be used at various layers within the architecture lifecycle to be able to understand and…

Projects

  • Kroger Analytics Platform

    -

    I was working as an Enterprise Architecture Consultant helping Kroger to better define the relationship between Cloudera Hadoop, Netezza, and the Enterprise data warehouse. Kroger has a very well defined Logical Data Warehouse, our role in this project is to reduce a bit of redundancy, while ensuring future growth goes to the best suited platform. I leveraged Social Network Analysis to best understand the data flow processes through all of the systems within Kroger.

  • GMF Data Warehouse

    -

    I was a Data Architecture consultant providing expertise in Data Vault Methodology for an origination analytic project. We used Informatica as our ETL platform, Oracle as our database platform, and Cognos as our reporting platform. The entire Architecture was designed in ERWin as we pulled data from various sources and populated our data marts visualized with Cognos.
