If you have been charged with creating a data center directory, there are several ways to go about this. However, it should be noted that not every data center directory option is necessarily the best choice for each situation, so you must take the nature of the data and its users into account before creating a directory. With that said, you should first inquire as to who will be using your data center directory, and what they are most likely to search for. Once you have those points in mind, ask yourself how best to make your data center directory easily searchable for these regular users.
For instance, if you are creating a data center directory that focuses largely on individual names, it pays to make the data center directory based primarily on the alphabetical spelling of the last names of entrants. However, if you are creating a data center directory that deals in inventory, it might be a better idea to categorize the items into different groups before taking any further steps. And if your data center directory is one that deals primarily with dates, it might help to select certain spans of time, categorize the entries into different sub-groups from there, and then list each individual entry according to a logical, easily applied system.
Once you have these aspects of designing a data center directory in mind, go ahead and compile things as you see fit in order to offer an intuitive, easy to use directory for the everyday person. Once you have done so, go ahead and test all options in the data center directory you have created in order to make sure that all functions are correct, and that the average layperson can grasp the basics of your data center directory in order to find what they need in minimal time for best results!
