　　大学四年学习生涯,让我有了质的蜕变，专业技能、个人处世能力、人生目标和信仰加强提高和具体化,但每一次的突破自我成长都是心酸的,因此我要感谢在我成长过程中支持、关心、帮助过我的人,也要感谢培育我的四川农业大学以及党和国家对贫困生的支持。

　　首先,感谢我的导师屈智成老师,在论文的写作过程中,给予我悉心的指导,屈老师一直以他严谨、一丝不苟的工作态度指导我、鼓励我，让我对论文充满了信心，帮助我克服一个又一个的技术难题。他深厚的计算机理论基础和他在计算机新技术方面的造诣，以及不断探索的工作作风给我留下了深刻的印象。此外,屈老师还在专业发展,职业规划和人生目标完善等方面都给予我倾力指导和帮助,再次表示衷心的感谢！

　　其次,要感谢我的同学和朋友老师,在我困难的时候,是他们的理解关心和支持让我渡过一次次难关,没有他们的帮助,我不可能读完大学,对我给他们带来的麻烦表示深深的歉意和真诚的感谢。

　　最后,也要感谢X公司的关心和培训,大三暑假,接受了我这个一无经验,二无相关技能的实习生的加入,还给予了培养,在公司期间,我详细地了解了公司的运作方式,管理员工办法,公司的完善的制度和“以人为本”企业精神深深的感染了我,但成立的时间短,使它的信息管理还停留在纸质化,改变这种落后的方式就是本文写作的初衷。

　　谢谢关心、支持和帮助我的同学老师父母和朋友,同时也感谢论文答辩组的老师们，你们辛苦了，祝愿你们身体健康，万事如意!
