i'm considering pursuing an undergraduate degree in computer science, but i'm also thinking perhaps software engineering could be more appropriate for me. can someone explain the real difference?

for some background: i'm a b-sch graduate who considers myself a tech entrepreneur as well. i'm fascinated by the idea of "software eating the world" and i believe i have very good ideas that if executed well, can become viable businesses and even disrupt industries. i don't see myself being a software engineer or a computer scientist, but the purpose of my pursuing a second undergrad degree in this field is because i want to have a technical understanding of my business, i.e i want to be a technical founder. i am particularly interested in developing web-based products, or consumer-facing products delivered through the internet.

which is the route i should choose?
