API is the wings for the take-off of online applications!
If you are developing online applications, you may find it difficult to enter the market and hard to increase your membership. If you still follow the old way of thinking, then your online application will definitely have no future.
The SAAS platform I am in charge of - Caike Online Accounting website - has been developed for more than 3 years. The real take-off of Caike Accounting website started in the second half of 2008. Given that the domestic environment is not yet mature, it is relatively difficult to promote SAAS applications. From the second half of 2008 to now, the registered users of Caike Accounting website account for four-fifths of the total users.
