which is faster between Sqlite and dictionary?

For my game there are lots of information about monters, heros, items and so on.

And I will save them into containers as a database.

I want to know which is faster between Dictionary template or sqlite.

Option 1. Use Dictionary template.

Save data into Dictionary and find a item with key like

Value cItem = Dictionary[key];

Option 2. Use sqlite.

Create table for each group of information and query what I want to find.

Briefly, I want to pick faster one either dictionary or Sqlite as a database of all of the information about my game.

Any ideas?
