CRUD in NodeJs with MongoDB: Explanations

Knoldus

enmHere we are, in this post we are going to create a CRUD application in NodeJs with mongoDB as database and ejs as a templating engine.

You can download the application from here: github

Before diving in to this post please checkout my previous post, then you will get to know why i choose ejs as a templating engine.

In next post we will use Angularjs instead these templating engines.

Prerequisite: Not much but for creating a CRUD app you must be knowing the basics like:

NodeJs: what it is, why we use it, its packages etc.
MongoDB: Collections, models, schema etc.
EJS: JavaScript and some basics loops in it.

Lets start coding…

Did Someone Say Java 9 ??

Knoldus

In our previous blog , we discussed the features that were added in Java 8.
More than three years after the release of Java 8, the next version is now just around the corner with a tentative release date of September 21st, 2017.

java9-meta

You may have heard about Java 9’s module system, but there’s even more to this new version. In this blog, We will try to cover some of them.

One can download JDK 9 EA (Early Access) software from Java 9 Download

Introduction to FIX protocol for Trading

Knoldus

The Financial Information eXchange(FIX) protocol is an electronic communications protocol initiated in 1992 for international real-time exchange of information related to the securities transactions and markets. It was initiated by a group of institutions interested in streamlining their trading processes. These firms believed that they, and the industry as a whole, could benefit from efficiencies derived through the creation of a standard for the electronic communication of indications, orders, and executions. The result is FIX, an open message standard controlled by no single entity that can be structured to match the requirements of each firm.

FIX has become the language of the global financial markets used extensively by buy and sell-side firms, trading platforms and even regulators to communicate trade information. This non-proprietary, free and open standard is constantly being developed to support evolving business and regulatory needs and is used by thousands of firms every day to complete…

Difference between RDD , DF and DS in Spark

Knoldus

In this blog I try to cover the difference between RDD, DF and DS. much of you have a little bit confused about RDD, DF and DS. so don’t worry after this blog everything will be clear.

With Spark2.0 release, there are 3 types of data abstractions which Spark officially provides now to use: RDD, DataFrame and DataSet.

so let’s start some discussion about it.

Resilient Distributed Datasets (RDDs) – Rdd is is a fault-tolerant collection of elements that can be operated on in parallel.
By the rdd, we can perform operations on data on the different nodes of the same cluster parallelly so it’s helpful in increasing the performance.

How we can create the RDD

Spark context(sc) helps to create the rdd in the spark. it can create the rdd from –

  1. external storage system like HDFS, HBase, or any data source offering a Hadoop InputFormat.
  2. parallelizing an…
