The software that this text will introduce is a multifunction learn the single phrase software, mainly introduced this software manufacture environment, the manufacture process, to operation and its operation methods of the customer can search the single phrase according to own demand, increasing the single phrase, deleting the single phrase, editting single phrase etc..Moreover, it returned to provide a good method that carries on the back the single phrase for the single phrase customer can pass to establish an user39。s name to recite from memory the single any time look into own history record, for the purpose of assurance recite from memory the degree of progress on to elaborate carefully from the angle of the software is Adapt Server Anywhere that the development tool of that system is the powerbuilder databases of the usages.
