The history of the development of database technology can be divided into three phases : the first generation is the reticulation / hierarchical data model based on database ; the second generation is the relational data model based database ; the third generation database which has the object oriented character breakthroughs the localization of the traditional database model which is unable to build model based on complex data structure . the third generation has led the database system to a new time
