MS Access -- best strategy for boolean value in table and interface

Hi all -- looking for some quick input on good strategies for capturing Boolean values in an MS Access table along with corresponding ease-of-development with the front end. I know the question seems easy but I don't like the yes/no check in the table (is this really how it's done?) and I'm used to seeing numbers. I'm thinking the most straightforward strategy is to use a Long datatype and then tie an option group to it at the form level -- then I can populate with integers based on each value and I can control the default to either one or the other and presumably avoid null values as well. From an upsizing standpoint -- when I upsize, what does MSSQL use as integers to distinguish between true and false -- (-1) and (0), or something else? Just trying to make sure I make the right design decisions now and avoid headaches later. Thanks --

I think you should use Boolean (i.e. Yes/No) in Access. They're easy to deal with, and the entire Access infrastructure "understands" them. When you upsize, most upsizing "wizards" will make the right choice to handle those Boolean fields. You could use a numeric datatype, but you're just making extra work for yourself.

The "Yes/No" is just more ... human-readable, I guess. Remember that Access was (and still is) intended for the Power User, who may not quite understand what Boolean means, and what those values (0, and anything NOT 0) really mean. Yes and No are definitive to the average user, so Access uses those.

Most use a Bit datatype when storing boolean values in MSSQL Server, with a Default of 0.
