JAVIER, JOHN IVERSON S.                        INFORMATION MANAGEMENT BSCS 1D  XML , which stands for eXtensible Markup Language, is a flexible way of organizing and moving data in a structured form. It uses tags to show how data should be arranged in a document, so both people and machines can easily understand it. With XML, users can make their own tags and structures to fit their specific needs. Because it organizes data like a tree, with smaller parts fitting inside bigger ones, it's great for handling complicated relationships between different pieces of information. XML is used in lots of areas, like making websites, sharing data between programs, and setting up configurations, because it works on any system and is supported by many different programming languages and tools. JSON , which stands for JavaScript Object Notation, is a way to share data between a server and a web app that's easy and light. It looks a lot ...

JAVIER JOHN IVERSON S. BSCS 1D SQL , or Structured Query Language , is like the language used to talk to databases. It helps us manage and get information from big sets of data stored in databases. With SQL , we can do things like find specific information, add new data, change existing stuff, or even get rid of things we don't need anymore. It's like having a special key to unlock a treasure chest full of useful information. Think of it this way: Imagine you have a giant library with books all over the place. SQL is like the librarian who helps you find the book you want. You can ask SQL questions like "Show me all the books by this author" or "Tell me how many books were published this year." SQL understands these questions and finds the answers for you in the database. It's like having a super-smart assistant who can find what you need quickly. And it's not just about finding stuff – SQL also helps organize data. Just like we put things in di...

JAVIER, JOHN IVERSON S. BSSCS 1D  DATA DEFINITION LANGUAGE (DDL): The Data Definition Language ( DDL ) is a group of commands in SQL (Structured Query Language) that helps create, change, or remove database objects like tables, indexes, views, and rules. It's like the plans for building a house. It tells us how to make rooms (tables), what each room is for (columns and their types), and the rules for organizing things (constraints).  INTERACTIVE DATA MANIPULATION LANGUAGE (IDML): The Interactive Data Manipulation Language (IDML) is a set of SQL commands that lets us handle and change data in a database. It's like the tools we use to move, arrange, or clean furniture in a house. We can add new stuff (insert data), rearrange what's there (update data), remove things (delete data), or just look around (retrieve data).  EMBEDDED DATA MANIPULATION LANGUAGE (EDML): The Embedded Data Manipulation Language (EDML) means using SQL commands inside a programming language like C, ...
