In Star Wars the Old Republic professions are known as Crew Skills. Crew Skills are essential to the game because they allow you to craft powerful and useful items using your gathered resources. The Star Wars galaxy however, is so large that gathering the right resources without interrupting your current adventure might be difficult. So the good news is this is where your companions come into play. You can have your companions (your crew) head out to gather resources for you. They can also craft items for you and complete a missions on their own.
There are three categories of Crew Skills: Gathering Skills, Crafting Skills, and Mission skills. There are three Crew Skill slots and you are allowed to have more than one Gathering or Mission Crew Skills but you are only allowed one Crafting Crew Skill.
There are six categories of Crafting Skills: Armormech, Armstech, Artifice, Biochem, Cybertech, and Synthweaving. All of the resources you and your crew gather will be used to actually make items using the Crafting Skill. Your crew will be able to craft weapons, armor, stimulants and other very useful items for you to use. Like the Gathering skill, you can sell crafted items on the open market for money. You can only have one Crafting Skill put into your Crew Skill slots.

There are four categories of Gathering Skills: Archaeology, Bioanalysis, Scavenging, and Slicing.

Details on each of the gathering skills are listed below.
Archaeology is the ability to seek out imbued items such as ancient artifacts and Lightsaber crystals. It has the same concept as mining in World of Warcraft.

These items are also used in Synthweaving to create items used by Force players (i.e. Sith Inquisitors and Jedi Consulars).
Bioanalysis is the practice of collecting genetic material from creatures and plants. This skill goes hand in hand with the Biochem Crafting skill.
