In order to encode documents in a way that is both machine- and human-readable, XML requires a set of rules. Similar to HTML, XML stores data in a hierarchical format. However, XML is concentrated on describing the structure and substance of data, in contrast to HTML, which is largely used for displaying and formatting web content. It offers a method for creating unique tags and elements to represent data in a particular domain or application. Elements, attributes, and text content are all parts of an XML document. Start and end tags are used to enclose elements, and they are capable of having child elements. The start tag of an element contains the attributes that are used to describe the element in more detail. The data that is present in an element is represented by text content. Many different ap...

INFORMATION MANAGEMENT CLASS

MY EXPERIENCE IN INFORMATION MANAGEMENT CLASS By: Brian Gabriel Gonzales Being a BS in Information and Technology student, I expected already that we'd have this kind of subject. Information management is all about teaching us how to manage, organize, sort out, and use the different types of information that we, as users, are receiving and giving off to the computer, device, or any other medium that we are using. At first, it's kind of hard to understand since it's our first time taking this class. The first lesson that we learned is about databases, since that is the main purpose of this subject. It's a little bit confusing for me because it has different definitions, but the main purpose of this is to organize data. And I'm looking forward to us making our own database for our project. Our information management class, both lecture and laboratory, is fun and exciting. It's just that I enjoy more the laboratory part since we are doing hands-on activities, and I...
