SQL stands for  Structured Query Language also called See- Quel. This is a domain specific language used for programming and designed for managing data held in the relational database management system or simply the ( RDBMS ) and also for the stream processing in a Relational Database Management System or ,(RDBSMS). It is used for handling Structured Data. SQL consists of many types of statements which can be informally classed as Sublanguages : A Data Query Language, A Data Definition Language, A Data Control Language, and A Data Manipulation Language. The scope of SQL includes Data Query, Data Definition, Data Acess Control. SQL is a Declarative Language, it also includes procedural Elements.  The first relational language to be utilized in E.F.Codd's relational model was SQL. That model was described in his influential paper of the late 1970's.  Although it was not entirely adhered to the relational model described by E.F.Codd , it became the most widely used DATA...

What is Database ? For understanding a Database, Let's see what is a Data. A Data is an any kind of information. For eg: the data of a person is his/her height, weight, gender etc.  In the same way a Database can be defined as a systematic collection of data which supports electronic storage and manipulation of data. To give an example of a database a telephone directory is the best ex. So, in that stays all the details of a person. Wright!  In a relational database stays the details of a person in rows and columns & tables which make it easier to find with SQL & NOSQL queries . As of this writing SPARQL is the only querry accepted by the World Wide Web or simply the (www). Types of DATABASE.  Databases have evolved with time . Earlier in the late 1980s it was with Object-Oriented Database and today with SQL & NOSQL & CLOUD DATABASE .  Relational Database. A Relational Database , invented in the IBM by Sir E.F.Codd in 1970 so that it can be accessed...

Crtpt - stands for hidden & graphy  - stands for writing. It is the process of protecting or securing a data or information with the help of codes.  Yes, the data gets stored in the form of codes such as : " 8b1a9953c4611296a827abf8c47804d7" Can you guess the actual word ? It's ' Hello'  similarly " 64ef07ce3e4b420c334227eecb3b3f4c " is the code or the hash for " Cryptography ". This technique is derived from some mathematical concepts . This process of crypting texts or the plain texts  into cipher text or the crypted text   is called Cryptography. If I give an example of Cryptography then WhatsApp will be the best to explain. Did you ever notice that after writing the first text to a person in WhatsApp at the top the message appears as "End-to-end encrypted". Hence it ensures you that " now your message is encrypted and is totally saved securely" , but in time when needed it can also be decrypted too.  This process of ...

  Passwords ! This is the key to this digital era. Passwords are the most important thing which should be highly secured. Passwords are given everywhere to name some are: Social medias, Cell phones,Laptops, Desktops... etc. Now to access these things you need your passwords and this is the only thing an attacker or the bad guys need to take control over your Life.

Now to only open your device you need to give your password and then you'll be able to access your credentials...Now just imagine that I have all your passwords and can access you details so now what will be the result? I can do whatever I wish to do to exploit your accounts,  ...

We often use Social Media... in our daily life ... We come across many things let's say "uncountable" .... Wright! . So , in this blog I'm here to say something about it. This is to create an Awareness among people especially children under the age of fifteen who don't know much about "Phishing" .... This trick is all about tricking the human mind just like a "Snap" . We humans think ourselves to be intelligent but in reality we aren't. This trick is performed to trick this stupid human mind with what it wants . In this trick the attacker will send you a link THIS IS DONE IN MOST OF THE CASES ... Let's say the link will be something like this: www.google.com .... Now you'll think this link to be the official one & you click it now after clicking that you'll get a page asking for your google account... let's say you gave your username & password , then you'll see again that page popping up, Now the page that ha...
