The Portland Observatory: Big Data - Variety For Smart
Our goal is to be a catalyst for change - to improve the
quality of life for citizens in Portland through the use of
Big Data technologies. We strive to help Portland improve
safety, sustainability and
effectiveness by turning data into information and
insight useful to citizens and decision makers.
PORTAL is the Portland-Vancouver transportation data
archive with a recent expansion to Central Lane County.
PORTAL archives multi-modal transportation-related data to preserve the
data and provide a resource for local agencies and
students. PORTAL's web
site provides tools for analysis of traffic and transit
data to support operations, planning and performance measures.
Fall 2012 I taught
CS 410/510 Database System Implementation - Fall 2012
(Counts as CS 587)
My goals for the class are to give you insight into the internal
structure of database systems (primarily relational
database systems) and to give you some hands-on implementation experience with database systems.
Data Streams (Winter 2012)
Periodically I teach a data streams course
(CS 410-510 Data Streams)
with Prof. Dave Maier. This course was offered for the
fourth time in Winter 2012.
