Want to learn about basic structure of blog..

Answer 1

anyway, you could also simplify that dynamic structure by handling public access as static html pages, and back end as using host functionnalities to publish / remove static article pages... but that's more like a classical website ^^

you are also advised to use CMS ready made frameworks (such as wordpress) to avoid developping (and debugging) your own blog engine ;P

Answer 2

blogs are basically collection of articles

articles are stored / saved in database

basic blog structure have two main parts: any user (public) access / owner (private) access... former is used to only display article(s), later add capacity of write / publish article(s)

blogs are basically accessed through at least these kind of urls:

public access:

+ home page: display most recent articles (usually only titles and eventually sample of article start, date of publication)

+ article page: display full article based on article id passed as query string

private:

+ login form: used to owner connection and authorize back end private access

+ back end page: used to write / publish / remove article(s)

that's the minimal requierements for a blog structure... however, less or more features could be added, such as search functionality, comment functionality (often along with user creation with right access / login-logout), handling private moderation features, and so on...
