XML      What is XML? The Extensible Markup Language (XML) is  a simple text-based format for representing structured information: documents, data, configuration, books, transactions, invoices, and much more . It was derived from an older standard format called SGML (ISO 8879), in order to be more suitable for Web use JSON     Moving on to JSON , it is a text-based data format following JavaScript object syntax, which was popularized by Douglas Crockford  Even though it closely resembles JavaScript object literal syntax, it can be used independently from JavaScript, and many programming environments feature the ability to read (parse) and generate JSON.     I s a string whose format very much resembles JavaScript object literal format. You can include the same basic data types inside JSON as you can in a standard JavaScript object  strings, numbers, arrays, booleans, and other object literals. This allows you to construct a data hierarchy. AJAX   AJAX or " Asynchronous JavaScript

SQL or " Structured Query Language ",  is a standardized programming language that is used to manage relational databases and perform various operations on the data in them, it is honestly an easy language to learn . If you understand programming and already know some other languages, you can learn SQL in a few weeks. If you're a beginner, completely new to programming, it can take longer. Now for a bonus question, should you use SQL? Well it is  a better fit for heavy duty or complex transactions because it's more stable and ensure data integrity . You need to ensure ACID compliance. (Atomicity, Consistency, Isolation, Durability) or defining exactly how transactions interact with a database. You don't anticipate a lot of changes or growth, compared to python, the significant difference between SQL and Python is that  SQL is used to access and extract data from a database . At the same ti

Embedded Data Manipulation Language Now what about embedded data manipulation language?

Last blog we talked about what exactly a DBMS  (Database Management System)  is, but now let's dig in a little deeper about it, what it's functions and pros and cons are.

DATA DEFINITION The DBMS must be able to accept data definitions(external, internal and conceptual schemas, and all associated mappings) in source form and convert to the appropriate object form.   DATA MANIPULATION The DBMS must be able to handle request from the user to retrieve and possibly update existing data in the database, or to add a new data to the database. DATA SECURITY AND INTEGRITY The DBMS must be able to monitor user requests and reject any attempts to violate the security and integrity checks defined by the database administrator. DATA RECOVERY AND CONCURRENCY The DBMS must have the capability of recover from, or minimize the effects of a system crash. DATA DICTIONARY The DBMS must provide a system database called the
