title: Creating one-many relationship between street sections and car scans?
body: <p>I have two tables and need to create a one to many relationship between them. tlbsection represents a series of street sections as lines in a city. Each street section has its own id.
  tlbscans represents a on street scan of a street section counting cars on it. I need to relate tlbscans to tlbsection as a street section and can have more than one scan. What is a good way to do this with with the example data below?</p>
  <h2>tlbsections
  ID(PK) | geom  | section  |</h2>
  <p>1       | xy    |     5713 |</p>
  <p>2       | xy    |     5717 |</p>
  <h2>tlbscans
  section | a  | b   |</h2>
  <p>5713    | 30  |  19 |</p>
  <p>5717    | 2   |   1 |</p>
