Data Engineering Tools

   Data is a new oil. To channelize this data we need proper pipelines. These pipelines are mostly called ETL or data pipelines.  There are various tools out there to work out these Extract, Transform, and Load (ETL) operations.  Some of the scripting tools are:  - Python - SQL and NoSQL Apache provides a wide range of products that can be used as Data Engineering tools.  Some of the amazing apache DE services comprised of; - Hadoop - Spark - Kafka - Cassandra - Hive In addition, some cool DE tools are: - Tableau - Talend - MapReduce These DE tools provide a way to manage the data pipelines in a more effective, efficient, and better way.  Almost every Data-Oriented company in the corporate sector is highly dependent upon these technologies. They are leveraging many of the above-mentioned mechanisms for promising Data Services and Architecture. That's it for today. Hope you have enjoyed this article. If you want to know more about data or software relat...

NoSQL database

-
Image
  Data is everywhere, it is expanding with each passing day. Relational Database systems are kind of fixed and static. When we have something in abundance and without any standard formation, then the tables of relational database systems cry out.  So what to do with so many data integrations from several structured as well as unstructured sources. Well, the answer is to go for NoSQL (Not Only SQL). SQL is a structured query language that is used to query Relational Databases. However, NoSQL database does not contain data in the form of relations. Most of the NoSQL databases follow the JSON type structure to store data.    Formal Definition:      Guru99  provides a pretty nice definition for NoSQL databases: " NoSQL Database  is a non-relational Data Management System, that does not require a fixed schema. It avoids joins and is easy to scale. The major purpose of using a NoSQL database is for distributed data stores with humongous data stora...

Good Pieces of Advice for Freshers

-
Image
To let you know a few useful things, I asked some experienced people, and here is what they have for you... Be open to changes. Focus on improving your soft / people skills. It will be hard sometimes but believe in yourself. You have got it. ( Rahat-Undergraduate ) Try to do good in quizzes and OHTs (One hour test or mids) cause when finals don't go well, these can help in getting good gpa which are comparatively easy then finals. ( Ayesha Munir-Undergraduate )   A few years later when you would look back at this time, GPA won't make you happy, but the memories of these 4 years will. Your career is important but so is having a good time. So work hard, party harder! ( Haris-Undergraduate ) From the start try to build your connections with seniors because they know more than you and.. are best counselors.. Focus on your quizzes and assignments because they are the building blocks of your Grade.. Your Good Image play some important part for favoritism points in exam....

Applications of Data Engineering

-
Image
In a previous blog post about data engineering, we went through several many concepts related to data engineering such as data modeling, and then we went through different types of databases, for example, relational databases and we also got a glimpse of relational as well as NoSQL databases. And in today's blog post we will be writing about data engineer applications. Which are basically the use cases of data engineering 1st let's see what data engineering applications mean; so basically when we have data and we have engineered it then there are several things that we can do with that data and these things that we can do with processed data are the use cases of the data engineering. For example: If we have filled our containers with the data then it's not of any good use if it is not clean and well-formed. If your data is well-formed and if there are no logical mistakes, missing values, and garbage then we can easily perform the use cases and applications of data enginee...

PHP chess board : how to make ?

-
Image
As we have learned much of the basics of  HTML and CSS . Let us now learn how can we make our web applications more user friendly, flexible and versatile, using php . Today we will see how to make a chess board using php in collaboration with HTML and CSS .  So, Let's start: BASIC php SYNTAX: Starting Closing Tags: <?php ?> Php code must be written in these tags. Variables:              Start with "$" sign e.g. $num=3;               ; is really important to put after every statement. Functions:              Functions start with the keyword "function". E.g. function power(){} Print:             echo "printing by using echo";             echo ("printing by using echo");             print "pri...

Relational Data Model

-
Image
In the previous blog post, we covered Data Modeling. We have seen that data modeling is really important before jumping into predictive modeling.  In this article, we will cover the Relational Data Model (RDM). Let's start from the very basics, relational means anything which is linked with some other thing. This link is called "Relationship". In RDM or RM there are major three types of relationship cardinalities (also called Multiplicities or Cardianalities): 1. One to one 2. One to many 3. Many to many We can understand these with the help of a few simple examples;  One to one: One department has one manager. One to many: One class has many students. Many to many: Many teachers can teach many students. Okay, so we have got an abstract overview of the term " Relational ", now the next thing is " Data ", data covers everything, anything... And finally, " Model " means something in the form of a template, design, a kind of blueprint.  To store...

Data Modeling

-
Image
source: https://searchdatamanagement.techtarget.com/definition/data-modeling A wise person once said a picture is worth a thousand words . In real-world data is not just a few rows of excel sheet, yet it comprises several billion rows expanded through hundreds  of tables. A table is usually made up of rows and columns. Each table represents an Entity . Entity means an Object or thing. That Entity has several properties called Attributes . Those attributes represent the qualities or characteristics of the entity. Since there is more than one entity, so there should be a Relationship between those entities. If we look at the tables we cannot get a clear idea of the relationship between several tables/Entities. Hence, we need to represent the tables/data in the form of a picture or a flow graph. That flow graph or Entity-Relationship diagram is called a Data Model .  Data Modeling is a technique to represent how the tables are related to each other and to represent the s...

Let's write a Story..

HTML provides us the opportunity to write stories by using beautiful background and themes. Let us write a story using HTML (do not ignore CSS) (NOTE: I took the story from here ) HTML Code with Internal CSS: (The code within <style></style> tag is CSS code. This is used for styling.) <!DOCTYPE html> <html> <head><title></title></head> <style> body { background-image : url(https://ubisafe.org/images/leaf-transparent-gif-3.gif) ; } header { background-image : url(https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcTtDfPZ1vWpRDFkDl8dZ7h1IYsNolC3Mqos_7DitiaztuzI-8yi0w) ; width : 100 %; /*background-repeat: no-repeat;*/ text-align : center ; height : 100px ; padding-top : 0.1px ; padding-bottom : 17px ; } #header { } #container { background : white ; width : 50 %; padding : 20px ; text-align : justify ; margin-left : 25 %; border : 10px solid orange ; box-shadow: -...

Pintos : Series : Part3 : Project 1 : Alarm Clock

-
Image
The PintOS project has 27 test cases that we need to pass. In the first project we are just going for the five test cases related to alarm clock that are as under: alarm_multiple alarm_single alarm_simultaneous alarm_negative alarm_zero But before jumping into the code, let's first understand the basic structure of PintOS and how it runs. Consider the following diagram: Here QEMU is an emulator on which pintOS runs. Test cases are the processes that we run on the PintOS (Operating System). So we only need to modify the PintOS code, we are not allowed to make any change to the test cases code as this would be a cheating. When you open up the PintOS directory, in tests/threads/tests.c all the test cases are declared. And in the tests/threads/ directory you can observe files with the extension " .ck " and " .c ". So the " test_Name.c " files are the files in which test cases are defined, while " test_Name.ck " file...

You might have heard of the famous proverb: " Necessity is the mother of invention. " Let's tokenize this proverb, as a wise-man said:" Tokenization makes things easy to understand." So first thing is Necessity... Once upon a time, there was   a large company who wanted to create a website for e-commerce . The website was for 24/7 and large amount of data needed to be managed and maintained . For this the management team of the company decided to launch their website onto the server. Initially the website got Launched successfully, but one day in the fine morning the CEO woke up from his/her slumber and got the Phone call from the manager. The manager told the CEO that their site was down last night due to heavy traffic on the server. CEO called an emergency meeting, in the meeting, the company decided to buy more servers as their data as well as the users were increasing . So in order to deal with  the large amount of data and heavy traffic , the...
