Abstract
The National Taiwan University Hospital(NTUH) Health Information System(HIS) has been running for more than one year until now the HIS is working steadily without big problems. NTUH has been developing administration information system based on the existing architecture of WebService and HL7 over SOAP. To avoid the problems encountered during development of HIS, for example: division of labor for pages did not work properly, the user interface of pages are not consistent with each other, the management of library and interleaving of user interface codes with business logical codes made code files in a mess, some embedded SQL command leads to many errors and it was hard to debug. In the beginning of NTUH administration information system development, we targeted on these problems and added some rules and methods to improve these situations with minimal changes of the existing software architecture. For improving development architecture and the design flow of large scale software, we use SQL parameters, division of user interface codes and business logical codes, etc. which decrease mistakes caused by programmers. We offer new software architecture template, which can make division of labor easier, and people to develop a large scale system can follow our steps which help them decrease unnecessary mistakes and development time.
