It's a little tough without more information, but I'll give it a try.
Try creating 5 initial tables, for the workers, building, resources, units, and technologies. You'll probably need a player table as well. One idea would be to use a 'many-to-many' table to join the player table to the other tables. So for instance, you would have another table called player_workers, with two fields, player_id and worker_id. And so on...
A great place to start working through these issues is by researching database normalization. Very fascinating stuff as well.
Best of luck!
