Creating Tables (Database Control)

a. Create a new MS Access database named assignment2_yourname

b. Create a table named SurveysByHand with the following fields: SampleID, Plot, Year, Species, Mass, HindFoot, Tag. Choose the types appropriately for the following data. Make ID the primary key.

Table 1. Five data points from the Portal LTREB long-term rodent sampling database

| ID    | plot | year | species | weight | hindfoot |    tag |
| ----- | ---- | ---- | ------- | ------ | -------- | ------ |
| 21012 |    4 | 1993 |      DM |     42 |       36 | 1EA0F9 |
| 22012 |    4 | 1995 |      DM |     31 |       37 | 0D373C |
| 23012 |   17 | 1996 |      DM |     25 |       37 | 64C6CC |
| 24012 |   21 | 1996 |      PP |     26 |       22 | 1F511A |
| 25012 |   22 | 1997 |      DM |     53 |       35 |   2624 |

c. Take a minute and think about why we shouldn’t use tag as the primary key. When considering this question you need to know a simple fact about mammal trapping. Sometimes individuals escape at some point during processing (they may be small, but boy can they bite!) before all information can be collected or before the individual can be tagged.

d. Enter the data above into your table

e. Save and close the table. Congratulations - you’ve created your first relational database!
