Some database programs are massively bloated monsters chock-full of bells and whistles. Table Tool... isn't. Indeed, it's barely one step over using the Tab key to format data in a Notepad file.
Table Tool offers users the ability to create single-table databases, each table consisting of columns of untyped (i.e, text) data. There are no relations, no drop-down lists, no formatters, no entry checking, no indexes, no unique keys--nothing but columns of text. Furthermore, you cannot even enter data directly into the columns: You must double-click each column to bring up a small editor window, which you can then type in. You can add columns, move columns around, or delete columns, and of course you can search for a given text string, though you cannot limit the search to a given column.
Table Tool has one fairly unique feature: You can "Execute" the text of a field, for example, to launch an application. The best use for this is to create a Web link associated with a given record, for example, a link to an IMDB page for each record in a list of movies.
Given these limitations, who is Table Tool for? Well, it is very lightweight, running off a USB drive and needing no installation or registry permissions. It could be useful for people who must work with extremely minimal hardware, such as low-end netbooks. If it were freeware, I would regard it more highly, but for the asking price of $18, there are probably better solutions out there that will still fit the minimal requirements.
Note: This demo version is limited to 50 records.
