Databases versus plain text

Question

When dealing with small projects, what do you feel is the break even point for storing data in simple text files, hash tables, etc., versus using a real database? For small

Answer 1

As someone also doing research in Bioinformatics, I would suggest NOT using a database for these kinds of prototype projects unless you are sure it needs it. If you are on the fence, go with the databaseless solution and stick with flat files. It is also important to note that traditionally Bioinformatics researchers have go the flat file route, which means there are well defined file formats for most types of data in the feild. If you decide to go with a database solution, it may hurt your compatibility with existing research projects.
