DataBase Seminar for April - What's an ORM?

The April Database Seminar will be on THURSDAY, April 18. Please note the change from Wednesday to Thursday. We'll be at Engine Yard. Since this group hasn't been big on food, we'll just have some light refreshment once again.

Matt Lehner will talk about ORM (Object Relational Mapping). Here's what Wikipedia says. "Data management tasks in object-oriented (OO) programming are typically implemented by manipulating objects that are almost always non-scalar values. ... However, many popular database products such as structured query language database management systems (SQL DBMS) can only store and manipulate scalar values such as integers and strings organized within tables. The programmer must either convert the object values into groups of simpler values for storage in the database (and convert them back upon retrieval), or only use simple scalar values within the program. Object-relational mapping is used to implement the first approach." Now there's a mouthful or three! We look to Matt to help us make sense of this.

Matt was one of the founding members of the Buffalo Lab and previous Director. Matt also was a co-founder of a telecom VoIP startup and was the lead architect behind the Symfony2 based backend API for their internal phone systems, and front-end phone management and voicemails web interface.

Come one! Come all! Please do rsvp.
