Further more, the thesis lucubrates some key techniques: aiming at the management of the distributed objects, we skillfully construct the isomorphic project object tree for the real projects structure by using the CORBA naming service, and laconically and effectively implement the management of the services and modules by using the location service. And we also propose a design which uses CORBA event service and Borland MIDAS to implement the distributed data service in a creative way and analyze the advantages and disadvantages of this design at the same time.

In electronic payment system, it is more suitable to introduce the distributed electronic bank scheme in networks environment. However, in current scheme, the users obtain their cards issued by the bank in which they have opened their accounts and withdraw and store their e-coin at the bank. Due to limits of current network neckbottle and security, dispersed and mobile users in different areas, there are some defects in a practical monadic account e-bank scheme.
摘要在电子支付系统中,采用分布式电子银行方案更适合于网络运行环境,然而在现行的分布式电子银行方案中,每个用户局限在所开帐户的电子银行取得签发的Smart Card和提取或存储电子货币,由于网络的瓶颈作用和安全缺陷,以及用户所处地域的分散性和流动性等因素的限制、使得单一开户的银行方案在实际应用中其分布式特性并未充分得以发挥。
