| While
working on BuildDB/Buildapp
online Demo, I developed a little function
that will compact Access databases over the web.
Here's a "no-frills" page that'll compact the
databases for you.
One problem with Access databases is that "holes" are created when records are deleted, making the database fluffy and bloated. Compacting the database makes it lean and efficient again. Note: This function/page can easily be combined with the Buildapp front end file navigation and search pages (Installment II), to create an application that'll make it easy to handle this formerly troublesome chore for all the databases on your machine/web site.. |
