Comment on The problem with Database Abstraction Layers… by Chris Renner

Thanks for the comments Dan. I’ve actually begun using Zend_Db in the past couple of months and its growing on me rapidly. Once you get comfortable with the syntax it is not much more trouble than writing raw SQL, and I like the prepared statement features you get when using the PDO_MySql adapter. The inclusion of PDO was more or less from ignorance, and if I wrote the article fresh today there’s quite a bit I could write differently.

“Larger databases will see huge hits on performance if you try to return only primary keys for a result set, and then loop through the keys, creating an object for each”

I don’t know about other DALs, but Zend DB at least does not do that. If you do a fetchAll query for example, each row object is created from the data in the result set.

Also, not sure why you’ve mentioned PDO as a DAL – it has more or less exactly the same functionality as the php mysql_ functions, but in an object orientated manner.

Comment on Toggle Table Rows with jQuery, no plug-in required by Chris Renner

Hey Trent,

I don’t consider a little client side JS very expensive, unless perhaps the client is IE6 running on a Pentium 3 or some such. Most of my apps are MySQL driven, and though MySQL supports views, they are very inefficient as compared to the way views are implemented in, say, Oracle. I tend to prefer to minimize database transactions, since such actions produce noticeable slow downs in page load time.

Oh, and really cool to hear from you!

It’s interesting you chose to tackle the problem on the client-side. Have you considered creating a view to handle the table concatenation, and then using the view for your web app? The view only gets updated when the underlying tables are updated, and you save all the expensive query overhead your app is putting on the system.

Hi Chris.

Recently, I have created a new singleton class (datastorage), similar as Zend_Registry, but with namespaces and persistence included.

Would be interesting in extends Zend_Registry to make the same as my datastorage class ? Can be done ?

Thanks,

Xavier Pérez

I had to go back and check what ZF version I’m running…and it happens to be 1.10.3

Latest is 1.10.4 but it doesn’t look like there were any changes to Zend_Session on the latest release.

So far there’s no issues between my extension class and ZF 1.10
