Data processors spend the majority of their day inputting various company data into computers. This data can originate on paper forms, such as invoices, or it could be electronic, such as email. The data processor first checks the data contained in the form to make sure it's complete and that required information isn't missing. She then enters this data into a system. This can take the form of a text document such as Microsoft Word, a database system like Microsoft Access, an online web management system such as Salesforce, or propriety software specifically written for the organization.
