The Document Object Model
The Document Object Model (DOM) is a standard for representing XML and HTML documents as a navigable tree structure. Every object in the DOM tree is a node, with different node types like elements, text, and documents. The DOM allows developers to navigate and interact with an XML or HTML document by treating it as a tree of nodes.
INTRODUCTION TO DOM AND DOM TREE
The document describes the DOM tree and how it represents an HTML document. It contains three types of DOM nodes - element nodes for HTML tags, text nodes for text content, and attribute nodes for attribute values. It provides examples of traversing the DOM tree using properties like parentNode, childNodes and methods like getElementById. It also discusses how to dynamically add and remove nodes from the DOM using JavaScript methods like createElement, appendChild, setAttribute, and remove.

Object oriented programming in python
This document provides an introduction to object-oriented programming in Python. It discusses key concepts like classes, instances, inheritance, and modules. Classes group state and behavior together, and instances are created from classes. Methods defined inside a class have a self parameter. The __init__ method is called when an instance is created. Inheritance allows classes to extend existing classes. Modules package reusable code and data, and the import statement establishes dependencies between modules. The __name__ variable is used to determine if a file is being run directly or imported.
Functions with heap and stack
This document discusses the differences between the stack and heap in computer memory. The stack stores function parameters and local variables sequentially and follows LIFO order. The heap is reserved for dynamic memory allocation using malloc() and freed using free(). The stack has faster access but limited size, while the heap has no size limit but slower access and requires manual memory management. Examples are provided to illustrate how variables are stored in each.

It also covers lists, links, images, tables, forms, and using CSS for styling HTML pages. The document is intended as a training presentation on basic HTML elements and concepts.
Computer fundamentals
This document provides an overview of computer fundamentals including input devices, output devices, memory devices, pointing devices, hardware, software, and the benefits of computers. Input devices take data and control signals to process information, such as keyboards and mice. Output devices communicate processed information in a human readable form like monitors and printers. Memory devices store data and instructions, with primary storage holding short-term memory and secondary storage storing long-term. Pointing devices allow spatial input through physical gestures. Hardware refers to physical computer components while software represents programs that govern operations. Computers provide benefits like easier research, communication, business, and shopping due to their accuracy, speed, and ability to store retrievable data.
3 tier architecture
This document discusses 1, 2, and 3 tier architectures. The 1 tier architecture keeps all application elements together in one place and has simplicity but poor scalability. The 2 tier architecture provides a basic client-server model and improved scalability over 1 tier but does not divide application layers. The 3 tier architecture divides an application into presentation, business logic, and data storage tiers for improved scalability, security, and ability to upgrade individual tiers independently, though it is more complex to set up and maintain. The document promotes online courses from Baabtra to learn programming and become a software professional.
Normalization in databases
The document discusses database normalization. It defines normalization as organizing data to eliminate redundancy and ensure data dependencies. The document outlines several normal forms including 1NF, 2NF, 3NF and BCNF. It provides examples to demonstrate transforming a database from an unnormalized form to higher normal forms through removing anomalies and redundancies.
operator overloading in C++
Operator overloading allows the same operator to behave differently depending on the operands. It allows performing different operations on the same operands, making code more readable and allowing easy access to objects to perform operations. An example demonstrates overloading the decrement operator (--) in a class to decrement an integer count and displaying the result. Function overloading uses a single function name to perform different tasks based on parameters. An example overloads the area function to calculate the area of a circle, square, and rectangle depending on parameters passed.
Oops concept on c#

XML
This document provides an overview of XML including:
- XML stands for Extensible Markup Language and is used to carry data, not display it. Tags are user-defined.
- An XML example shows a simple note with predefined tags.
- XML schemas define valid elements, attributes, structure and data types for XML documents.
- XML documents form a tree structure with elements nested within a root element. Syntax rules ensure documents are well-formed.
- XML parsers like SAX and DOM are used to read and build a model of an XML document programmatically.
CrashCourse: XML technologies
Our CTO, Angel Gruev came up with quick Introduction to XML Technologies. (XML) is a markup language that defines a set of rules for encoding documents in a format which is both human-readable and machine-readable. It is defined by the W3C's XML 1.0 Specification and by several other related specifications, all of which are free open standards.

It tells about how dom really used in javascript & html.And it tells about its levels and its w3c standards. And some Dom example programs with source code and screenshots.
Processing XML with Java
The document discusses different XML parsers in Java including DOM, SAX, and StAX. DOM represents the XML document as an in-memory tree which allows flexible processing but uses more memory. SAX is event-driven and reads the XML sequentially using less memory. StAX is similar to SAX but simplified and "pull"-based where the developer manually navigates elements. The document also covers using JAXP for XML processing independence and the key classes involved in DOM and StAX parsing.
Xml Overview
The document provides an overview of XML for catalogers in 2009, covering XML basics, XML and MARC formats, usage scenarios, XML tools, and experimentation. It discusses XML syntax, schemas, validation, transformations with XSLT, and how XML can be used within library applications and for cataloging.

CTDA Workshop on XML and MODS
This workshop is intended for Connecticut Digital Archive participants to introduce them to xml and how MODS or metadata object description schema is implemented in the CTDA.
1 xml fundamentals
XML is a markup language similar to HTML but designed for carrying data rather than displaying it. It allows users to define their own elements and tags. XML documents use tags to describe and structure information and can be displayed using CSS or transformed using XSL. Key benefits of XML include its ability to describe hierarchical data, separate data from presentation, and enable data sharing across different systems.
XML
This document provides an overview of XML, XML schema, parsing XML, and GladeXML. It defines XML and its components like elements and attributes. It describes XML schema and provides a simple example. It explains how to parse an XML document into a DOM object and access elements.

XML Databases
There are similarities between XML and databases in terms of storage, querying, and APIs. Storing XML in databases allows for indexing, efficient storage, and support for multiple users, transactions, security, and locking. XML documents can be stored in databases either as data-centric or document-centric documents. Data-centric XML is usually generated by systems and element order does not matter, while document-centric XML has unpredictable structure and element order is important. Native XML databases store XML as the fundamental unit, while XML-enabled databases convert XML to a database model, which can result in loss of information like element order. Web services use XML languages like SOAP and WSDL to enable interoperable machine-to-machine communication over

The document then provides steps to create a login system using sessions: 1) Check login credentials and create a session variable on successful login, 2) Display user profile details on the profile page by fetching the session variable, 3) Include a logout link that destroys the session to end the user session. Key differences between cookies and sessions are also summarized - cookies are stored on the client while sessions are stored on the server.
Php database connectivity
This document provides an introduction and instructions for connecting a PHP application to a MySQL database. It discusses storing and retrieving data from the database. The key steps covered are:
1. Connecting to the MySQL server from PHP using mysql_connect().
2. Selecting the database to use with mysql_select_db().
3. Executing SQL queries to store/retrieve data with mysql_query().
4. Different mysql_fetch_* functions that can be used to retrieve rows of data from a database query.
An example task is provided where a registration form allows storing user data to a database table, and then retrieving and displaying the stored data in a table.
Chapter 6 database normalisation
The document discusses database normalization and the three forms of normalization. It provides examples of tables that violate each normal form and explains how to modify the tables to conform to the normal forms. The first normal form requires each field to contain a single value and related data to be stored in separate tables or fields. The second normal form eliminates redundant data by creating separate tables for values that apply to multiple records. The third normal form ensures non-key fields are fully dependent on the primary key and removes transitive dependencies.
Chapter 5 transactions and dcl statements
This document discusses transactions in SQL Server. It introduces transactions and their relevance in ensuring data integrity when multiple tables need to be updated together. Transactions group a set of database operations so that if any operation fails, all operations are rolled back. The document demonstrates creating a transaction using START TRANSACTION, COMMIT TRANSACTION, and ROLLBACK TRANSACTION statements. It also shows handling transactions within try/catch blocks so that failures cause a rollback. Transactions ensure atomicity and integrity by committing all operations together as a single unit, or rolling them all back if any fail.
Chapter 4 functions, views, indexing
The document discusses user defined functions (UDF), views, and indexing in SQL Server. It provides an example of a UDF that returns a teacher's name based on their ID. Key differences between stored procedures and UDFs are that UDFs are compiled at runtime, can't perform DML operations, and must return a value. Views are described as customized representations of data from tables that don't take up storage space themselves. Indexing improves the speed of operations by organizing data to allow faster searches.
Chapter 3 stored procedures
This document discusses stored procedures in SQL Server. It begins by explaining that stored procedures allow encapsulation of repetitive tasks and are stored in the database data dictionary. It then shows how stored procedures reduce network traffic and client-server communication compared to individual SQL statements. The document provides examples of how to create a stored procedure using CREATE PROCEDURE and how to call it using EXEC. It notes advantages like precompiled execution, reduced traffic, code reuse, and security control. It also demonstrates using parameters, loops, conditions and variables inside stored procedures.
