从事数据库相关工作已经十几年了,是因为自己内心的执着,一直执着于从事的oracle数据库的相关工作。我是从erp起步的,从技术难度上来说erp的开发不是特别难,数据库的数据量也不是很大,可以作为刚步职场的一个过渡阶段。如果从事erp开发,核心要掌握的就是存储过程的编写,因为大部分公司写后台都是用的存储过程,同时做erp开发的话如果感兴趣的话可以多学习些数据库设计发面的内容,比如表的设计,表与表关系的设计,可以画e-r图,也可以画系统流程图来梳理系统业务。目前感觉大的erp公司对开发者需求不多,比如国内著名的财务软件公司用友招聘的大部分是实施工程师,因为用友的NC软件是成型的改动量不是很大。 熟悉了一般的后台开发技术之后就可以往更高一层次的领域发展--数据挖掘工程师,也就是etl.需要我们从中挖掘出最优价值的数据。这个时候对技术的要求也就会高了,需要掌握并行,分区表等相关技术,涉及行业包括需要高级保密的银行,公安等领域。 在数据库的最高领域就是数据库DBA或者是称之为数据运维工程师,从事这个职位我认为最少应该有3年工作经验。需要了解数据库的体系结构,运行机制,数据库的原理等等。这个职位需要处理一些紧急情况比如数据库数据的恢复,数据库打补丁升级等等,也是挺考验技术的职位。‘
