Login Into Database

  1. Previous steps only makes us can connect to the "mentawai" database, now we'll need to set up GRASS to be able to do database operation in our table.
  2. Use menu Databases > Manage Database > Connect Database > Login to Database

  5. Our login information has been stored by GRASS, but is it correct? GRASS provides some connection test feature.
  6. Use menu Databases > Manage Database > Connect Database > Test Database
