Do you even know what the OP is talking about? None of those links show how to do as he requested. The first one converts to Microsoft Word format. The second one doesn't convert to a database, and the last one exports a database into PDF, the opposite of what he's trying to do.
dpari: Databases organize data using tables, or some type of format that clearly separates values and organizes them into columns and rows (e.g. CSV or Spreadsheet software) -- PDF documents are usually not in this format, so it isn't really practical to convert the text in them into a database.
Unless, of course, the PDF has the data organized in some way that would fit into a "table" or "database". Is there a particular PDF you need converted, or do you mean just in general?
