*Imported COMPUSTAT Data

**Built composite primary key from unique gvkeys cartesian-producted with years 1970 to 2015 (all other datasets will be joined onto this)

***This is '''yearsbygvkeys''' in SQL database

**Stripped out list of unique company names from COMPUSTAT data

**Used matcher to construct standardized company names, with lookup table to original names
