Like RentandInterest said the questions of how you want to format and manage your data are going to be the big determiners of what tools will work best for you.
If your needs doesn't fit the Wordpress mold or a per-existing solution like Daytum (which svdodge suggests) then rolling your own data scheme and interface using a more flexible CMS may be an option.
Silverstripe, Symphony CMS, and ModX are all very adaptable with Symphony, in my opinion, being the most agnostic to data scheme and intended use out of the box. It also has an impressive ability to output data into pretty much any text based format.
Rather than being traditional content management systems these examples are often described as content management frameworks instead.
Edit : Then again, something more akin to a straight MS Access database may be an option worth pursuing. A private Wiki may also fit.
Yup. On that topic, Drupal isn't much better. They're really big systems with a lot of fragmented and poorly formatted code, mainly because of how big they are.
Mainly the big issue is that the popular CMS' offer too many features in a base install.
You're much better with something like Symphony or Modx, which lets you add whatever you want to the base install with extensions afterwords, and keeps the base install simple.
Edit: Although this posts sucks from an English standpoint since I use the same words 978387 times. So derp I suck.
Try MODX.
It started out as an Etomite fork and has since been rewritten from the ground up with the same principles. I'm pretty sure its community is now actually bigger than Etomite's was and the core team is about 3 or 4 people. And it's really awesome.
I love MODx. I prefer that over all the other CMS's I've tried (it's technically a CMF - Content Management Framework). The forum is welcoming and very helpful, and it's great if you do the front-end stuff yourself, as there is not much theme support (however they do exist). The focus is mostly on security, and it does a great job separating the code into an MVC architecture. It's also incredibly fast due to caching and PDO.
In the backend, the entire sitemap is listed in the left side resources menu: http://modx.com/revolution/product/screenshots/
Everything is literally "filed" into folders. If you have a blog with hundreds of posts, you could see how the tree navigation would get unwieldy. I wouldn't say this is necessarily bad as it makes it really clear and easy for users to figure out where to add their content, however it does present some limitations with more complex content or dynamic pages made up of several distinct types of content.
have you looked at this? http://modx.com/extras/package/wayfinder
Can you describe how the nav is dynamic? I mean dynamic has 1001 different uses and they vary wildly. If you can spell out exactly how it will change. I can give you lots of direction
If you are some what familiar with HTML & CSS then you should use MODX, very powerful and very easy, I had my first website up and running within 30mins of hearing about this CMS.
However if you need help, it maybe a good idea to send a mock up screen of what you would like the frontpage to look like and then after a link is clicked, also how big would the default page be and how would you like the page to behave if the user re-sizes their web-browser to a smaller window.
You also need to take into account your target audience, does it include people with special needs (how will your site cater for them), will your users be using your site from mobile devices? and of course check to make sure it renders and behaves how you want it to behave with as many browsers as possible (most CMSs take care of this but it's good to test this before going live) good site to browsershots
The core issue here is, they are very very different.
http://modx.com/extras/package/provisioner Could try this, but you'll need to start with an older verison of MODX.. maybe 2.2 I think.
We had a script .. maybe I can post it someplace that would find / replace the database snippets calls with revo equivalents.
We've only done few backend only upgrades. 29 out of 30 times it makes sense to build anew with MODx Revo. Generally we're migrating to Bootstrap or Foundation anyway and lots of other newer methods of doing things.
I've used MODX for about 5 years now, and it's perfect.
I do a lot of bi/tri-lingual sites, and MODX makes it so easy. It's a bit of a learning curve, but I've just launched a site on it and it's been an absolutely blast. The client loves the MODX interface, too.
Couldn't recommend it enough, although I haven't used anything else (Drupal, etc.) before so I don't know how well they compare.
ClientConfig is excellent for allowing clients to update mundane stuff you'd normally stick in a chunk and not let them have access to. Use it all the time now. Worth also mentioning VersionX by the same author (Mark H) - he runs ModMore now and they have Redactor, ContentBlocks and a really good gallery plugin too.
Both CodeMirror and Ace have their issues, but CodeMirror is probably in a better state at the moment.
I've been using pdoTools for a while now, which has (almost) drop in replacements for all the basics: Wayfinder, getResources, GoogleSitemap, Breadcrumb, getResourceField, getPage, UltimateParent. It's decent.
Definitely check it out again, they have made a lot of great improvements both in the core and with new plugins/extras. For blogging check out the Articles extra.
If you only used Evolution, then definitely check out Revolution, it is amazingly powerful.
Feel free to message me at any point in the future if you want any more ModX tips :)
For something this simple, I think MODX would also work quite well.
The main benefit over Drupal is that you can start with a static HTML+CSS design and just drop in some simple tags to make it work with MODX, whereas with Drupal, Joomla etc. you generally start by hacking on a template that already exists (which is more restricting).
Since not everyone here will necessarily know "well-known" PHP packages it's probably worth giving a bit more info. I presume you're referring to the CMS http://modx.com/ and ecommerce software, http://www.magentocommerce.com/ ? If you're considering using a python web framework and that framework is django, I'd suggest you start here: http://djangopackages.com/ for alternatives.
Modx is a great cms with a great community behind it. I went to their website last night to discover that it had been redesigned.
I'm learning web design. I found myself looking at about three pages on the site for about an hour and a half, just examining the new design. It's beautiful. And the subtle details really make add up to make an impact.
