How to Install JDK 11 on Windows (Configuring the PATH)
Here are the detailed steps on how to install Oracle JDK 11 on Windows and configure the PATH to make it working from the command line. Steps are not 100% the same for the JDK from IBM. In our earlier article, we have discussed about the JVM. JVM is a need for many tools for designing and development which does not need coding in Java. Unless you properly configure Java, trying to run the program … [Read more...]
Why JVM is Called Virtual Machine?
The virtual machine part inside the phrase "Java Virtual Machine" often confuses many peoples with full virtualization. A Java Virtual Machine is an example of application virtualization. The Java Virtual Machine converts the compiled Java code into machine language to run it on the host computer. At that time, there was a concept named WORA (Write Once Run Anywhere). Today, we still have the idea … [Read more...]
How Data Sciences Can Determine the Future of Technology World
In the future, it is likely that individual products such as the iPhone or Amazon Echo speakers would no longer be at the centre of attention, but rather networking and the accompanying flood of data in the software-defined world and exist with the help of artificial intelligence. Already we can see the progress of wearable consumer products like Samsung Galaxy LTE. Ultimately the consistent … [Read more...]

It is capable to use NTP like ESP32 Arduino or smartphones with data connection or computers with active … [Read more...]
Monolithic Architecture vs Microservices
The basic idea behind a microservice architecture is that applications are easier to create and maintain when disassembled into small, seamlessly interacting parts. The software functionality is isolated in several independent modules. These are individually responsible for the execution of well-defined independent tasks. We have several articles on microservices to explain the basic matters, such … [Read more...]
The Need for Monitoring the Microservices Environment
Microservices are becoming increasingly popular in software development. The reason for this lies in the ever-increasing complexity of IT infrastructures. To keep track of microservice environments, real-time monitoring continuing to help. The traditional way of managing and expanding monolithic enterprise applications becomes problematic with their increasing size and complexity. Switching to … [Read more...]
What is OLAP and What is it Used For?
OLAP stands for Online Analytical Processing. OLAP is an application used to ease the query processing on data warehouse. The terminology OLAP was created by modifying the traditional database related term online transaction processing (OLTP). OLTP facilitates and also manages the transaction-oriented applications. OLAP is an approach to multi-dimensional analytical (MDA) queries and is a part of … [Read more...]
