Labview configuration files are very easy to use and can hold any type of information you wish. There are functions in the File palette ready to use for configuration files. A configuration file is similar to a registry entry. You can have sections and keys. So you can create a section called "Data1" and keys called "Name", "Age", etc. Create the same for a new section called "Data2", and so on. The functions are useful for writing the config file and reading from the file. To read a certain piece of data, just supply the section name and the key name. So you could ask for section "Data20", key "Name", and you would get the 20th name in the database (config file). This way you don't have to write code to search the database for certain items, the functions do it for you and they are already written. Look into config files. They are very easy to use, very useful, and very underused even by the most experienced LV programmer.
