全面的认知，在规定的时间内能够完成系统的开发。2.2经济可行性该系统是本人自愿开发，开发系统所需的设备和资源都已准备，不需要额外的支出，因此在经济方面不存在问题，该系统完全可以开发。2.2社会可行性（操作可行性）目前已有很多成功开发图书馆管理系统的先例，社会需要图书馆管理的现代化和信息化。图书馆管理系统开发和运行与国家的政策法规不存在任何冲突和抵触之处。另外，图书馆管理系统所采用的操作和工作方式符合工作人员和读者的日常习惯，而且操作方便灵活，便于学习，具有可行性。57

图书馆管理系统中涉及到的数据是图书馆中相当重要的信息，系统要提供方便的手段供系统维护人员进行数据的备份，日常的安全管理，系统意外崩溃时数据的恢复等工作。f.系统的标准性系统在设计开发使用过程中都要涉及到很多计算机硬件、软件。所有这些都要符合主流国际、国家和行业标准。同时，在自主开发本系统时，要进行良好的设计工作，制订行之有效的软件工程规范，保证代码的易读性、可操作性和可移植性。g.系统的先进性目前计算系统的技术发展相当快，应该保证系统在下个世纪仍旧是先进的，在系统的生命周期尽量做到系统的先进，充分完成企业信息处理的要求而不至于落后。这一方面通过系统的开放性和可扩充性，不断改善系统的功能完成。另一方面，在系统设计和开发的过程中，应在考虑成本的基础上尽量采用当前主流并先进且有良好发展前途的产品[10]。4.可支持性(无特殊需求)5.设计约束用户不得通过系统查找他人资料，图书馆也不得在未经他人允许泄露其资料。因为系统面临所有的用户，但是为了防止无聊者的恶意操作，必须约束用户的行为。像输入密码，若输错次数超过设定的次数，则暂时取消用户登录的权限。系统的修改、维护由开发人员以及图书馆共同负责。6.购买构建需求无特殊需求57
