Data file size... a couple hundred rows, 5-6 columns. type .. inventory.. low inventory items, if one person orders and it's no longer avail it needs to be reflected quickly. Server.. have not chosen one yet.. still in planning stages I don't want to lose any data. File will be displayed in order.. but update as refreshed, inventory may change rapidly. searching.. yes, there would be some searching involved. no. of users... not many at first.. I'm guessing 20-30 at the most. data item.. one problem is what if two uses select the same item at the same time. Thanks for the help.
