In order to solve the complexity of global schema maintainability in the existent heterogeneous databases integration frame-work,a new heterogeneous databases integration framework based on multidatabase language(HDIFBML) is presented.This paper consisted mainly of design of essential module,the concepts of global schema and schema mapping and definition of a mulitdatabase lan-guage SMSQL,which is schema mapping SQL,supports the definition or modificaition of the global schema and also resolves the potential confilcts due to structural and semantic heterogeneity of the integrated data.Practical application show that the operationality,maintainability and scalability of the framework is desirable.
