d4m_Baseball

This is a demo script with a self-contained and tested Matlab script showing the power of D4M on historical Baseball data. There are three parts:

1. Parsing data into a form ready for ingestion
2. Ingesting data into memory or an Accumulo Table
3. Querying data to answer several questions of interest

The goal is to provide a complete, well-documented example demonstrating how to use D4M for data analysis on a data set of manageable size. The techniques presented will scale to true big data scenarios.
