PeopleSoft Definitions for .Net developers
After going through some of the Oracle training, I can say that I have a much better understanding of PeopleSoft than what I previously did. I was not wrong in the way the physical box architecture was set up, but my understanding of the system was a little off. Here are some PeopleSoft definitions:
The way things are built in PeopleSoft is a little difficult to understand. The idea of a field, record, page, component, scroll, and gridview are completely off compared to a .Net world. Most of this comes from what Oracle uses as definitions for each of these items. For example a scroll in .Net might mean scrolling vertically withing a page. We (or at least I did) made this assumption as from a web/mobile background this is the typical way we define a scroll. Swiping is a left to right or horizontal motion to move things left or right. Scroll in PeopleSoft is simply a way to display one set of data at a time. You may think of a scroll as a pagination of data, except you only display one set of data at a time. It would be similar to paged tables in HTML, but instead of say 20 lines of data that you page through you are actually only showing one line of data in a nice layout. You then get some controls to move to the next line of data. For me this was a little counter intuitive at first. There are also somethings that go automatically in the background and have to do with levels, but I will get to that later.
Other PeopleSoft Definitions:
Field This is similar to a field or column in a database. Remember PeopleSoft is all database driven, I mean completely database driven. A field in PeopleSoft can be a field or column in the database, but it doesn’t necessarily have to be. Fields are the very lowest building blocks of a PeopleSoft page. They hold data, no matter if they are used in the database or simply on the page.
Record Is the next step up from a Field. You group a bunch of fields together to make a record. This is a template for what a line of data would look like in a database, again everything is database driven in PeopleSoft. Again a record may or may not be part of the a table in the database. It is simply a way to store data, either in memory for the page or in a database.
Page – All of these pieces come together to make a page, probably the most common way to interact with the data in PeopleSoft. Pages have levels and with these levels you can control the data relations on the page.
Component – Components are collections of pages and need to be registered with the PeopleSoft database in order for PeopleSoft to recognize them and add them to the system. There are a few other things that are involved with registering a component, but that is the basics.
GridView – Is the same as a table in regular HTML. You would use this to create rows of data to display to the user. Which is really what you would expect and you do have a gridview in ASP.Net so this is not that different.
Hope these definitions help with your understanding of PeopleSoft.
