Study Notes

HTML5

The <h1>...</h1> tags display text as a header with large, bold text.
The <figure> and <figcaption> elements define self-contained content with a caption.
The controls attribute for the <audio> element is placed outside the tag.
The default character encoding in HTML5 is UTF-8.

Databases

DDL (Data Definition Language) is used to define the structure of relations, delete relations, and perform tasks like creating relations.
The ORDER BY clause in a SQL query can be used to sort the data by multiple columns: column name ASC (ascending) and column name DESC (descending).

Software Development Life Cycle (SDLC)

There are four SDLC models:
- Waterfall
- Agile
- Incremental
- Spiral
The Spiral model was originally proposed by Barry Boehm.
The Incremental model allows for early product release and customer feedback on each increment.
The primary advantage of using the Incremental model is the ability to get a product to market early.

Bootstrap

.jumbotron is a Bootstrap class used to create a big box for calling extra attention.
The .dropdown class is used to create a dropdown menu.
There are 12 columns allowed in a Bootstrap grid.

CSS

A JavaScript method is a function stored as an object property.
The filter method can be used to iterate over an array and return a new array that contains only elements that meet a specified condition.

Responsive Web Design

The primary purpose of responsive web design is to make websites work well on different devices.
The <meta name="viewport" content="width=device-width, initial-scale=1.0"> tag is used to set the width of the viewport to match the device's width, which is essential for responsive design.
CSS media queries allow different stylesheets to be applied based on screen size or device.
When a background image is smaller than the screen, it will be repeated.

Data independence means that programs are not dependent on the physical or logical attributes of the data.
Data Manipulation Language (DML) is used in application programs to request data from the database management system.
