## Which Data Type is good For Primary Key

Which Data Type is good For Primary Key The most important thing of a table is defining the primary key; it could be single column based or the composite primary key.   In my development life, I saw a lot of primary key with different type or patterns. Such as …

## KwikStik KwikStuk

KwikStik? KwikStuk! During a recent electronics show my attention was drawn by a strange small orange device on display at the Freescale booth. It turned out to be the Kinetis KwikStik and a very enthusiastic Freescale employee immediately showed me its features and explained that it was fully compatible with …

## What is USER DEFINE Data Type and Its Implementation

What is USER DEFINE Data Type and It’s Implementation   User define data type are based on system data type of MS SQL Server. It is created when several table object use the same data in terms of data type, length and null ability. For example if we create the …

## Reverse engineering The new Wiring S board

Reverse engineering? The new Wiring S board In the fall of 2008 I started researching Arduino for an introductory article for Elektor. In that article I wrote that Arduino can be seen as a simplification of Wiring. The Arduino environment is very much like Wiring but slightly simplified and the …

## Numerical Methods Solution of nonlinear equations by using Bisection method in C

Numerical Methods: Solution of non-linear equations by using Bisection method in C Algorithm: Declare and initialize necessary variables like up_range, mid, low_range etc. Read the range( upper and lower)  from user within which the root of the equation  is to be calculated.
