Is there a better way to get/store information about a item than my current method?

Question

If I have created a new enum for example:

enum itemName{
    shortsword, ironChestplate, leatherCap}

And for each of those items I had fixed information about each item, what would be the best way to store and retrieve the data? Currently I use a series of conversion methods that use switch statements to return the correct information, for example:

itemType convertItemNameToItemType(itemName itemName){
    switch(itemName){
        case itemName.shortsword:
            return itemType.handEquipment;
        case itemName.ironChestplate:
            return itemType.bodyEquipment;
        case itemName.leatherCap:
            return itemType.headEquipment;
        }
      }

int convertItemNameToItemCost(itemName itemName){
    switch(itemName){
        case itemName.shortsword:
            return 3;
        case itemName.ironChestplate:
            return 8;
        case itemName.leatherCap:
            return 2;
        }
      }

These are just examples but there are more conversion methods to return more information about the said item, as well as many more items. This means that there is a lot of bulky code with the amount of switch statements.

Is there a better way to store and retrieve this information? This information will not be changed throughout the running of the program.

Thanks.

Edit: By better I mean a more efficient and less bulky way to gather the information about a enum, rather than just using a switch statement. The data I may want to get is (more columns are needed but this is just a example):

itemName	itemType	itemCost	itemTrainingRequirement
shortsword	handEquipment	3	martial
ironChestplate	bodyEquipment	8	martial
leatherCap	headEquipment	2	none

and currently I only have switch statements to convert from one to another when I need to.
