3. -2- Analysis of Economic and Business Issues System Context xDB converter converts the POI data into xDB file Control panel allows editing the search category and order

4. -3- Analysis of Economic and Business Issues Internationalization Issue Search method select –Generally required function: Search by name / address / zip code –What about “search by telephone number”? –What if the telephone data is adhoc and so huge? (e.g. China, India) –It does not make any sense to include this function for a few nations Search by address –Korea / Japan City/Province ( 시 / 도 )  district ( 구 / 군 )  village ( 읍 / 면 / 동 )  Address number 4 levels, From bigger to smaller –Western country Street name  Zip code or Town name  Address number 3 levels, From smaller to bigger –Each country has different address system Multi-language format –Asian letters need 2 byte –The unit in data format should be even number

5. -4- Analysis of Economic and Business Issues Two Feasible Solutions (1) Solution 1: Independent converter for locations –Build the independent converter (e.g. Korea, North America, China, Japan, etc.) –Pros: Each converter is free from the change request from other locations –Cons: Relatively large development effort Solution 2: One converter for various locations –Build one converter for multi-locations –Pros: The initial development effort is not as high as solution 1 –Cons: Complexity in implementation

6. -5- Analysis of Economic and Business Issues Two Feasible Solutions (2) Initial development cost –Solution 1 > Solution 2 –Why: 3 or 4 different converter applications have to be developed Maintenance cost –Solution 1 < Solution 2 –Why: The lower maintenance cost for the more simple system Decision: What is the most beneficial in which case?

7. -6- Analysis of Economic and Business Issues Assumptions Maintenance cost will be increased as time goes by. Lines of Code = Costs –One dollar per line The Number of developers in both solutions is same.
