Study Notes

Hypertext Markup Language (HTML)

HTML is the standard for publishing web content.
It uses an SGML vocabulary.

Standard Generalized Markup Language (SGML)

SGML is the meta-language for defining document markup languages.
It is the predecessor of HTML and XML.

Self-Definable Tags (XML)

XML documents use tags in a hierarchical structure.
Comments within an XML file are ignored by processors.

Extensible Markup Language (XML)

XML is a flexible way to organize and store data.
XML data can be shared in different applications.
XML documents contain elements with attributes.
Text is located between opening and closing tags.
Entities are characters that cannot be typed.
Prefixes are declared for namespaces within a document.

XML 1.0

It describes the syntax for XML documents (elements and attributes).
It specifies the rules for XML syntax.

XML Schema

It defines the structure of XML documents.
It is a next-generation data validation format.

Validation (XML)

Validation involves checking for correct XML syntax rules.
XML documents are well-formed if their syntax is correct.

XML Declaration

It declares the version of XML and encoding.
It's usually the first line in an XML document.

Markup Languages

Markup languages use sequences of characters to define text or word processing files.

Extensibility (XML)

XML uses text and nested tags, enabling flexibility.
XML can describe any data that can be expressed as text.

Document Type Definitions (DTD)

DTD defines the structure and sections of XML documents.

Namespaces (XML)

Namespaces help resolve naming conflicts in combined XML vocabularies.
Resources are grouped under unique identifiers.

HTTP POST

Using HTTP to send new data.

Uniform Resource Identifier (URL)

A URL identifies resources in RESTful systems.

ROY FIELDING

He introduced the REST concept in his doctoral dissertation.

HTTP DELETE

Using HTTP to remove data.

HTTP GET

Using HTTP to retrieve data.

HTTP PUT

Using HTTP to update data.

NoUNS, Verbs, Representations (REST)

Resources (nouns), actions (verbs), and representations (format like JSON or XML), are essential parts of REST.

REPRESENTATIONAL STATE TRANSFER (REST)

A style of software architecture for distributed hypermedia systems.
REST focuses on networked resources.

Data (REST)

Data is the content of resources.
This includes documents or images.

Representations (REST)

Resources are represented in formats like JSON or HTML.

Interconnected Resource Representations (REST)

RESTful resources are interconnected through URLs, allowing progression between states.

Stateless (REST)

REST requests contain all necessary information.
Client requests don't rely on server memory.

Client-Server (REST)

Client requests resources from the server.
The server responds without maintaining internal state.

Uniform Interface (REST)

Generic interface for accessing resources.

Components (REST)

Proxies, gateways, clients, and servers are the REST architecture building blocks.

Named Resources (REST)

Named resources, identified by URLs, are essential for REST systems.

Caching (REST)

Improving network efficiency, responses can be stored or marked cacheable.

Connectors

Connectors link components in a REST system.

PowerShell

Scripting language for managing systems.

PowerShell DSC

Configuration framework in PowerShell.

PowerShell Console

Similar to command prompt.

CMDLETS

Compiled code in PowerShell.

Get-Process

Listing running processes.

ps1

Extension file for PowerShell scripts.

Whatif

Parameter to test scenarios in PowerShell.

Concatenation (PowerShell)

Operator to combine strings together.

Format-Table

Formatting data on rows and columns.

Get-Member

Retrieving properties and methods of objects.

Echo (PowerShell)

Displaying variables or strings on the console.

Arithmetic (PowerShell)

Operators for numerical calculations.

PowerShell Pipeline

Joining statements using | symbol.

XML Stylesheets

XSL transforms XML documents.
Root element in XSL is xsl:stylesheet.

XML Creation

Creating XML documents.
book, title, author, are XML elements for books.

XML

XML documents define data with tags.
XML's structure uses root element and nested elements.
