自行改错，答案见文后
【答案】
第二句话，插入语usually referred to as the database属于修饰成分，可直接去掉，不影响主干。真正主语是The collection，而of data是介词短语修饰collection，仅修饰主语，不改变主语单复数。
因此，英语谓语要与真正的主语保持一致，也就是改为The collection ... contains。
【知识拓展：定语】
句子成分拆解：
第一句里头，a set of programs to access those data其中to access those data是不定式作后置定语，修饰programs，相当于programs that access those data。
第二句话，usually referred to as the database修饰collection of data，相当于The collection of data, (which is) usually referred to as the database。
第二句，information relevant to an enterprise中的relevant to an enterprise是形容词短语后置修饰information，相当于information that is relevant to an enterprise。
第三句话，a way to do sth固定搭配，表示“一种……的方法”。
to store and retrieve database information是不定式修饰way。
即：a wayto store database informationand(to) retrieve database information。
并列不定式，省略了第二个to。
