Consider a channel with 1 MHz bandwidth and an SNR of 63 a W

Consider a channel with 1 MHz bandwidth and an SNR of 63. (a) What is the upper limit to the data rate that the channel can carry? (b) The result of part(a) is the upper limit However, at a practical matter, better error performance will be achieved at a lower data rate, Assume we choose a data rate of 2/3 as the maximum theoretical ML How many signal levels are needed to achieve We data rate?

Relational databases have been in use for a long time. They became popular thanks to management systems that implement the relational model extremely well, which has proven to be a great way to work with data [especially for mission-critical applications].

In this DigitalOcean article, we are going to try to understand the core differences of some of the most commonly used and popular relational database management systems (RDBMS). We will explore their fundamental differences in terms of features and functionality, how they work, and when one excels over the other in order to help developers with choosing a RDBMS.
