Excerpt of article text...
I presented a couple sessions at the ARBP Real Studio Summit this past March in Atlanta. For my databases session, I gave an overview of some databases that work well with Real Studio and then I talked about object-relational mappers.
Although I briefly touched on the topic of ORM many years ago in this column, it seems like it is worth revisiting.
Object-Relational Mapping Overview
During my session, I asked the audience: "How many of you use an ORM in your projects?". Out of 45 people or so, only 2 or 3 raised their hands. I was quite surprised by this because I rarely have a project that doesn't use an ORM. In talking with people after the session, it seems like a lot of people are interested in the topic, but don't quite understand how to get started.
Simply stated, an ORM is a way to deal with your relational database in an object-oriented way.
Without using an ORM you will communicate with your database using SQL, RecordSets, DatabaseRecords and other features of Real Studio. This all works well enough, but it is not object-oriented and can get a bit repetitive. It also tends to result in your database code being sprinkled throughout your application, which can become a problem if you ever need to switch to another database engine, for example.
