Chapter 9 Question:
1. A join is a combination between two data tables in one table and a relate is when a record in the layer attribute table may have many matches in the non-spatial table. When tables are related, one can highlight records in either table to see matching records in the other. An example for a join would be locations of malls and the relate would be a table attribute that show the stores inside the mall.
Chapter 8&10 Question:
1. Three common operators used in spatial queries >, <, and =.

Lab 6

For this lab I decided to pick a certain county of California, therefore I chose the San Joaquin County in Stockton, CA. For both maps I inserted the census blocks just to show the county of San Joaquin for display because I was one of the students undergoing the range issues of this lab. I chose earthquakes for my second map because if one is from the state of California, earthquakes are one of the major natural disasters and I was curious to see if Northern California exhibited a good amount of earthquakes. I noticed that majority of the northwest coastline of Northern California had a fair amount of shock, but when one notices the northeast of the San Joaquin County there are very little quakes that take place in this county, which makes sense.
