Why Data Lakes Are Crucial to Business Analytics and Big Data Process

Big data is a sort of Data addition that contains greater variety, arriving in increasing volumes and with more velocity which is also called three Vs.

Bulky volumes of data have the power to address the illustrations that were hard to even store before. 

Gathering data for customer patterns, Internet of Things (IoT), the emergence of Machine Learning, more data came out, such cloud computing and NoSQL expanded Big Data possibilities and popularity even further.

A Fast and Space Efficient Library to Deal with Data in Dart, Flutter

Dart Data is a fast and space efficient library to deal with data in Dart, Flutter and the web. As of today this mostly includes data structures and algorithms for vectors and matrices, but at some point might also include graphs and other mathematical structures.

This library is open source, stable and well tested. Development happens on GitHub. Feel free to report issues or create a pull-request there. General questions are best asked on StackOverflow.

The package is hosted on dart packages. Up-to-date class documentation is created with every release.

Tutorial

Below are step-by-step instructions of how to use this library. More elaborate examples are included with the examples.

Installation

Follow the installation instructions on dart packages.

Import the core-package into your Dart code using:

import 'package:data/data.dart';

How to solve a linear equation?

Solve 'A * x = b', where 'A' is a matrix and 'b' a vector:

final a = Matrix<double>.fromRows(DataType.float64, [
  [2, 1, 1],
  [1, 3, 2],
  [1, 0, 0],
]);
final b = Vector<double>.fromList(DataType.float64, [4, 5, 6]);
final x = a.solve(b.columnMatrix).column(0);
print(x.format(valuePrinter: Printer.fixed()); // prints '6 15 -23'

How to find the eigenvalues of a matrix?

Find the eigenvalues of a matrix 'A':

final a = Matrix<double>.fromRows(DataType.float64, [
  [1, 0, 0, -1],
  [0, -1, 0, 0],
  [0, 0, 1, -1],
  [-1, 0, -1, 0],
]);
final decomposition = a.eigenvalue;
final eigenvalues = Vector<double>.fromList(
    DataType.float64, decomposition.realEigenvalues);
print(eigenvalues.format(valuePrinter: Printer.fixed(precision: 1))); // prints '-1.0 -1.0 1.0 2.0'

How to find all the roots of a polynomial?

To find the roots of x^5 + -8x^4 + -72x^3 + 242x^2 + 1847x + 2310:

final polynomial = Polynomial.fromCoefficients(DataType.int32, [1, -8, -72, 242, 1847, 2310]);
final roots = polynomial.roots;
print(roots.map((root) => root.real)); // [-5, -3, -2, 7, 11]
print(roots.map((root) => root.imaginary)); // [0, 0, 0, 0, 0]

Misc

License

The MIT License, see LICENSE.

The matrix decomposition algorithms are a direct port of the JAMA: A Java Matrix Package, that is released under public domain.

Use this package as a library

Depend on it

Run this command:

With Dart:

 $ dart pub add data

With Flutter:

 $ flutter pub add data

This will add a line like this to your package's pubspec.yaml (and run an implicit dart pub get):

dependencies:
  data: ^0.9.0

Alternatively, your editor might support dart pub get or flutter pub get. Check the docs for your editor to learn more.

Import it

Now in your Dart code, you can use:

import 'package:data/data.dart'; 

example/README.md

Data Examples

This package contains examples to illustrate the use of Data. A tutorial and full documentation is contained in the package description and API documentation.

Magic Square

Generates magic squares of different sizes and computes interesting decomposition properties of the matrices.

Detailed Instructions on How to analyze Data In Python

Data Analysis using Python

Python is the internationally acclaimed programming language to help handle your data better for a variety of causes. It’s crucial to gather, process, and analyze the data flow and do that as quickly and accurately.
One of the main factors why it is used for the analysis of data is the excellent Python ecosystem. There are tons of data-centric Python packages that make data analysis a lot quick and convenient.

In this project, we will have a completely hands-on and understand analyzing the Bike-sharing data for a company that wants to understand the bike’s and riders’ demand based on the different variables. We will also understand and find the variables that might affect the bike’s and ridership’s demand.

Learn About Best Data Lineage Tools

Data is the main part of every machine learning model. Your model is only as good as the data it’s built with, and you can’t build a model at all without data. This improvement might lead to: finding errors in the data, implementing effective changes to reduce risk.
creating better data mapping systems.
Some writers say that data is the new oil. Data scientists, data engineers, and Machine Learning engineers rely on data to build correct models and applications. It can help to understand the necessary journey of the data before it can be used to build accurate models.
