Think of it as a SQL database in your web browser.

Example #1:

Let's say you have a collection of products and you want to find every product that costs less $10 and is not a book. Simple, just write some JavaScript:

products.find({price:{lessthan:10},
              type:{not:"Book"}});

Example #2:

Let's say you want to update every product from XZYDesign and set the status to not available:

products.update({status:"NA"},
                {manufacturer:"XZYDesign"});

Example #3:

Let's say you want to sort your products based on type, price ascending, and quantity ascending:

products.orderBy(
   ["type",{"price":"asc"},{"quantity":"asc"}]
);
