VO’s are centralized containers of business data. VO’s offer storage and retrieval of it’s own data through Getters/Setters. They are easily accessible, passed around and portable, updated and bindable. All of these factors have increased production and ease of programming on this large scale project, and attributed to the ease of use in the project.

The custom VO classes we use have lighten the load of developing a complex project through their storage of simple, and on occasion more complex, data types. VO’s are a timer saver in that one call can be made to have all the data stored and ready to use versus making multiple calls whenever a piece of data is needed, which is something you’d probably never want to do in the first place.

One more thing that makes VO’s so valuable is the ability to POST and GET VO’s in their entirety which leads to matching data in, matching data out and through this we have consistency in our data.

The value of Value Objects is immeasurable in terms of making your life easier when it comes to developing projects of any size. Just the amount of time you will end up saving makes VO’s a must in your development war chest.
