Learn SQL Tutorial to Store, Manipulate Data faster and easier


For many years spreadsheets like Excel have been used to store data and records. These spreadsheet applications are approachable, ubiquitous, and flexible. They can merge cells, add comments, pivot on data, format tables, and make graphs. But with flexibility comes risk. They can lead to more work, more waiting, more versioning headaches, and lower accuracy. However with the availability of SQL, records can be stored much faster and easier. You can learn SQL through SQL tutorial on various educational websites. Here’s how SQL works –
  • Your data is stored in a relational database, which is made of tables. Those tables usually look like one sheet in Excel, with rows and columns.
  • You retrieve data and perform analysis with queries, which are a sets of instructions written in SQL. You can save them the same way you save a text file.
  • Instead of describing how to get the data—like in Excel or Sheets—your queries describe what data you want. You can run these queries with a SQL interpreter, which does the necessary retrieval and analysis steps for you.

SQL is much faster than any spreadsheet applications. It can take minutes in SQL to do what it takes nearly an hour to do in a spreadsheet. While popular spreadsheets like Excel can technically handle one million rows, you can store, manipulate millions of data in seconds using SQL.

C Programing – How to Code a Program in C Language

Everyone has studied C, either in school or in college. It is the basic programing language taught in student life. C programing is one of the oldest but effective computer language used worldwide. It is clean, simple and easy to get. Coding in C requires the understanding of datatypes, data structure, pointers, loop and syntax available in C library. To write a simple program of hello world, you can use - #include <stdio.h> int main() { print f(“hello world”); return 0; } This simple code demonstrate how C programming is done. The execution of a C program starts from the main() function. The printf() is a library function to send formatted output to the screen. In this program, the printf() displays Hello, World! text on the screen. The return 0; statement is the "Exit status" of the program. In simple terms, program ends with this statement.

Make Your Learning Easy Through C++ Tutorial

C++ is an enhanced version of the C language. C++ includes everything that’s part of C and adds support for object-oriented programming (OOP). In addition, C++ also contains many improvements and features that make it a “better C,” independent of object oriented programming. Learning C++ can become easy through C++ tutorial . It gives you basic idea about the language, its usage and how it can benefit your career ahead. Moreover, you will learn how to think, put logic and code effectively in C++. Some advantages of learning C++ are - It is useful for the low-level programming language and very efficient for general purpose. C++ provide performance and memory efficiency. It provides a high-level abstraction C++ used re-usability of code. C++ used inheritance, polymorphism.
