摘要

MALPHA是一种用于操作构成关系数据库集合的数据的语言。它将E. Γ的著名数据库操作语言ALPHA推广到这个环境中。科德。MALPHA提出的原则也可能导致MQUEL、MSQL等。由于用户通常要面对多个数据库，因此多数据库操作语言应该比数据库操作语言更有用。

MALPHA: A relatiohal multidatabase manipulation language

MALPHA is a language for manipulations of data that constitute collections of relational databases. It generalizes to this environment the well known database manipulation language ALPHA of E. Γ. Codd. The principles that MALPHA proposes may also lead to MQUEL, MSQL etc. Since users typically face more than one database, the multidatabase manipulation languages should reveal more useful than the database ones.
