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...

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.

In this blog post, we will be done with our Pintos Project #1 and this Pintos Series AlhumdullillAllah. so let's start...

Marketing

I am of the opinion that everyone of us must acquire marketing skill.  Why Should We? This is because, as the world population is increasing, there is a demand for more. If we have certain talent, skill, or if we are capable of doing some task. Then, we can see there are others, who can do the same task. But, our opinion is that : We are the best in our work. So, how can we tell this to the person who needs our services? We need to devise a marketing policy, so that we and the other person gets benefit from it. Robert T. Kiyosaki describes in his book : " Rich Dad Poor Dad " that,  McDonald's is a brand that sells ham burgers. Their ham burgers might not be the best, but they might believe them to be. Like wisely we can also make burgers, and there is a huge possibility that our burgers are the most delicious ones, but we are unable to sell it like McDonald's. Why? The answer is their marketing policy! ( ya, along with other aspects too ) Moreover, ...

Framework, libraries and services are usually overlapped. In this blog post we'll see how are these things different from one another. First let's have a look at framework .. Let's tokenize this word. Framework is composed of two terms. one is frame and second is work. Frame is anything that you can put something into . Like a photo frame, you have some sort of skeleton in which you can put your photo. but the most important thing is that your photo must be of the size of the frame. If this isn't the case then you might need to buy some other frame or you might need to cut your photo from the borders, or the bottom or the sides or from anywhere. (in order to fit it into the frame) The second word is "work" what does work mean... Well according to Physics you are only doing work if and only if some force is applied and you cover displacement in the direction of applied force. But this is not the case with this work word. Here the work is nothing ...
