Abstract:

SPL (SoftwareProduct Line) is the hotspot of the research of software reuse, this paper in view of the defects of present SPL, analyzes these defects and gives the countermeasures. A process model and a seamless migration model of SPL based on software library are put forward, and a car\|embedded multi\|media system(simulation) are demonstrated based on the  process model. Relying on the  functions of  storage and retrieval of relational database. Application of the two models is conducive to reduce initial investment and contribute to the migration of SPL, and has a certain practical value and popularization value.

Key words: software production line(SPL), software reuse, software library, model
