: The World-Wide-Web contains data that cannot be constrained by a schema. Another source for such data is heterogenous corporate systems which are integrated in order to get better service for the users. Such data is commonly called semistructured data. Semistructured data has been under intensive investigation during the last few years. The main focus of interest has been on the development of new data models and new query languages. The most widely used data model for representing semistructured data is a graph-like or tree-like structure. The problem is to develop a model which could be all-embracing. In order to develop such a model we have introduced a new model called the Adjacency Model (AM). Our model is a general model which can be used to represent semistructured data as well as relational data.
