DataMgr 2.5 Beta 1

Thu, 02 Sep 2010 12:00:00-0500

So I released the Alpha of DataMgr 2.5 more than a year ago. This is about as long as I have gone between a release. Why so long? Well, basically I have been neglecting DataMgr a bit to work on other things (more on that in another post). Also because DataMgr has been doing everything I want. Finally, however, I have the first beta of DataMgr 2.5 ready. [More]

DataMgr 2.2.0.3 Released

Wed, 04 Aug 2010 14:30:00-0500

DataMgr 2.2.0.3 Released This may be the first release of DataMgr in which I have made no significant contribution myself. This is a small point release, but could actually have a big impact. This release consists of a few small database-specific bug fixes from the 2.5 branch and two significant enhancements. [More]

DataMgr hits 2000 Downloads!

Tue, 08 Dec 2009 08:20:00-0500

I happened to look at my RIAForge page yesterday and I saw that DataMgr has been downloaded 2,000 times. This doesn't actually encompass all of the downloads as the project had been around since before I put it on RIAForge, but it is still an exciting milestone. What is DataMgr? This really inspires me to double my efforts on DataMgr 2.5.

DataMgr is Better than ColdFusion ORM

Tue, 22 Sep 2009 09:00:00-0500

I have been thinking this for some time, but it seemed like hubris (and flame bait) to say it. So be it - it needs to be said. I worry that ColdFusion ORM is being / will be marketed where it isn't appropriate. (What is DataMgr?)

What is Better?

It can't be helped, "better" is a word that only makes sense in the context of goals to be met. After all, it is impossible to tell if a sedan is better than a truck unless you know your goals. Do you need to get to work on low gas mileage or haul cargo? I will use the criteria that Adobe ColdFusion engineer, Rupesh Kumar, has laid out in "ColdFusion ORM - An Evolution in building datacentric application": [More]

Extending DataMgr 2.5

Thu, 03 Sep 2009 10:00:00-0500

One of the new features in the upcoming DataMgr 2.5 release that I am really excited about is the ability to extend DataMgr to add or modify its functionality to your liking. This is a feature that John Farrar really had to push me into. Now that I finally see the light, however, I am really excited about the possibilities. [More]

DataMgr 2.5 Alpha 1

Tue, 25 Aug 2009 12:45:00-0500

It has been seven months since DataMgr 2.2 was released and now DataMgr 2.5 Alpha 1 is finally available. I have gotten quite a bit of help on this version, both in terms of ideas as well as code. [More]

DataMgr Basics

Mon, 22 Jun 2009 09:00:00-0500

I saw a comment recently that said of DataMgr "His project does a lot more than what i need, otherwise I would use it myself. ". This was in the context of suggesting someone look at DataMgr, so I certainly don't want to seem ungrateful. Even so, this got me thinking. I have certainly seen programs that do so much that the extra stuff gets in the way of doing the easy stuff. I don't think that is the case with DataMgr, however. The download for the current version of DataMgr (2.2.0.2) is a 71KB zipped file (under 400KB unzipped) - hardly massive. So, how hard is it to use? I have a database on my local computer named "TestSQL" that has a table named "widgets". Fields in this table include "color" and "size". Here is actual code to save a widget to the widgets table: [More]

DataMgr 2.2.0.2 and com.sebtools Build 2

Mon, 15 Jun 2009 07:30:00-0500

I just fixed a couple of bugs in DataMgr which caused an update in both DataMgr and in the com.sebtools pack. The com.sebtools package also includes an update to FileMgr among other components. [More]

Using Filters in Relation Field Definitions

Mon, 04 May 2009 09:00:00-0500

Using Filters in Relation Field Definitions It recently came to my attention that I haven't yet covered in blogs or documentation one of the most powerful features in DataMgr. I have covered relation fields and filters, but (until now) not how to use a filter in a relation field definition. [More]

DataMgr 2.2.0.1 Released

Fri, 24 Apr 2009 13:30:00-0500

In the last several weeks, I have gotten a few bug reports on DataMgr 2.2. Most of them are fixed in this release. [More]

DataMgr 2.2 is Gold!

Mon, 26 Jan 2009 07:00:00-0500

After more than a year in development, including plenty of help from others, DataMgr 2.2 is now in final release state. [More]

DataMgr 2.2 Release Candidate (with Documentation!)

Wed, 07 Jan 2009 07:20:00-0500

The last beta of DataMgr 2.2 was released just over a month ago and things seem to have gone smoothly so I am going to release at as release candidate. Assuming that no problems are found with this build, the final version of 2.2 should follow shortly. [More]

DAL / Persistence Layer Comparisons

Fri, 19 Dec 2008 08:30:00-0500

I was curious yesterday about which databases were supported by which ColdFusion Data Access Layers (DALs). I went to check on that and before I knew it, I had compiled quite a few comparisons on each. Perhaps I should back up at this point and explain what I mean by a DAL. I DAL is any application that manages access to data (usually a database). These are often referred to as an ORM. An ORM, however, is one type of DAL (one that maps objects to a database). An ORM is a DAL, but a DAL need not be an ORM. [More]

DataMgr 2.2 Compatibility for Custom Relations

Fri, 05 Dec 2008 07:00:00-0500

(What is DataMgr?) I have tried to ensure that each version of DataMgr is completely backward compatible with every previous version of DataMgr. With version 2.2, however, I did introduce a small compatibility issue that may require a change in code. The 2.2 code will work on previous versions, but code written for previous versions may need a small adjustment for new versions. The reason for this is that while relation fields can call other relation fields, sometimes the combination doesn't make sense. For example, it does make sense to have a "label" relation that gets the value of a "sum" relation for another table. It doesn't make sense, however, to do a sum on a "concat" field (or any normal field that isn't numeric). It also isn't possible for any relation field to get the value from a "list" relation.

DataMgr 2.2 Beta 3 (with Railo support!)

Wed, 03 Dec 2008 08:00:00-0500

Coming just 6 weeks after the previous beta, DataMgr 2.2 Beta 3 is ready and I expect it is pretty close to the final release. [More]
