I'm sure I wont be the only one to tell you but a CMS without a database wont scale well. But I guess it will work just fine for a personal site.
It depends, from what I've seen (and worked with) a lot of companies only need a few pages on their site with the ability to edit them at will. This keeps down maintenance cost as they don't need to hire someone to do the updates for them, can be hosted on a simple no-database hosting plan that only accommodates for static web pages and provides the ability for the designer to be the only one involved in the entire process. So that if a design element changes, they make the change, and won't require a developer to implement those changes into the CMS written. It will scale perfectly because the design is separate from any programming that might hinder it growing to a full-scale CMS or even e-commerce system, so starting out with a basic "here we are, this is what we do" site to a more complex site is perfectly do-able and within budget, because for a larger more scalable (or e-commerce) site, you'll pay more.
So when the time comes to scale up, you already have the design, you only need some developer to implement that into the newer system
Ok, let say I need to send a sms to client and the sms needs to be in the client's preferred language. I also do not want to be in control of message bundles inside my project as that makes it difficult for business to easily make updates (That and it's a pain in the @ss being in control of the labels when business keeps on changing it). So when we need to add a message to a sms for example we just call CMS with a specific code for the message we want and CMS will return the the message in the correct language.
Hope this helps
Huh? As with any editor, as ek afrikaans tik or if I type english 或者如果我输入中文, it will display whatever language I type it as in. So if you need the site to be in a specific preferred language, you'll create the page for it, and (with pagelime I think) you can add some PHP code to it for it to decide which page to show... this is a *simple* non-database driven site. Think of it as FrontPage publisher (only way less gay and more functional without putting more code in that it actually takes to display something)
