Web Content Management Systems (CMS): WordPress & WooCommerce
Idea in plain words
Web CMS: Software application allowing non-technical users to create, edit, manage, and publish digital web content without writing raw HTML/CSS.
Exam tip
High-yield exam topic (High).
Explanation
WordPress powers over 40% of all websites globally. Its plugin and theme architecture enables rapid deployment of enterprise web stores. WooCommerce hooks into the WordPress database schema, adding custom post types for products and orders. To maintain security, CMS installations must strictly sanitize user inputs, apply principle-of-least-privilege database user credentials, enforce SSL encryption, and maintain automated plugin vulnerability patch cycles.
Key points
- Core CMS Architecture: Content Management Application (CMA - graphical user interface) and Content Delivery Application (CDA - compiles backend code into rendered web pages).
- Monolithic CMS (WordPress, Joomla, Drupal) vs Headless CMS (Strapi, Sanity).
- E-Commerce Extensions: WooCommerce turns standard WordPress into a fully functional shopping cart with catalog, tax, and shipping management.
- Security Hardening: SQL injection prevention, cross-site scripting (XSS) filters, secure authentication plugins, and automated database backups.
Example
Example
Configuring a custom shipping zone in WooCommerce that applies flat-rate delivery charges inside Kathmandu Valley and weight-based courier rates for external districts.
Code examples

WordPress / WooCommerce Database Core Entity Relationships:
wp_posts -> Stores product data (post_type = 'product')
wp_postmeta -> Stores product metadata (_price, _sku, _stock)
wp_woocommerce_order_items -> Line items belonging to orders
wp_woocommerce_order_itemmeta -> Line item details (quantity, tax, subtotal)
