modify those existing heterogeneous e‐CMSs is hard, expensive, and time consuming. Therefore very few government bodies could realize benefits from those e‐CMS interconnections. The e‐CMS interconnection development, using client side web page modification technique, has been performed with ten ministerial departments and many provincial branches.
Figure 6 shows software architecture of e‐CMS interconnection development. The figure shows letter sender on the left side and letter receiver on the right. For each side the software development consists of two parts; data exchange part( eCMSX) and client side web page modification( WebMod) part. The data exchange part is identical to all e‐CMS software therefore this part is developed once and deployed to all. Since the WebMod part depends on each e‐CMS web page design therefore it has to be individually designed and developed. For the sender side WebMod # 1 is designed to modify web page in which sending letter information is entered or populated by end user. When the user submits the send letter information, WebMod # 1 retrieves the information on the fly and send to the receiver through eCMSX.

Figure 7 shows screen layout of the e‐CMS sending letter information entry page. It includes letter ID, subject, sender, receiver and letter’ s content. On the left side after the send letter information is entered, the button‘ Save’ is then pressed to submit the information. On the right side the modified web page is illustrated. The‘ Save’ button is changed to‘ Send’. When the button is pressed the WebMod # 1 catches the information then send the receiver through eCMSX.
