Geometric Operations in NoSQL and Intro to Graph Databases

Geometric Operations in NoSQL:

Most NoSQL databases allow for certain types geospatial operations but they are usually oriented towards point queries. This presentation goes over a hybrid geohash approach for storing and querying on polygons in key-value store database, specifically Accumulo. I will also show how to create a custom iterator using JTS (Java Topology Suite) to run different types of geospatial queries.

Intro to Graph Databases:

Within the commonly accepted four categories of NOSQL -- key-values, column-family, document stores and graphs -- graph databases occupy the richest data-model but less scalable corner. We'll introduce Neo4j, a high-performance graph database, covering the basic of the data model, querying and a look at real-world applications.
