The marginal recursive equations on excess-of-loss reinsurance treaty are investignted, under the assumption that the number of claims belongs to the family consisting of Poisson, binomial and negative binomial, and that the severity distribution has bounded continuous density function. On conditional of the numbers of claims associated with the reinsurer and the cedent, some recursive equations are obtained for the marginal distributions of the total payments of the reinsurer and the cedent.
With XML standards playing more and more important role at information exchanges in data management,the XML database storing strategy which supports huge amount XML data control from bottom layer of database hasbecome the key part of fields such as content management. This article proposes an efficiently XML storing strategyfrom the perspective of constraint schema of XML instance based on XML Schema path analysis.
