Hello Data Analyst,

Let's discuss data models & benefits of having solid data models.

One of a data analyst's key responsibilities is building a strong data model.

The term "Data Model" refers to the process of arranging data into tables based on relationships & groups...
...to minimize duplication and maximize efficiency.

By performing this task properly, you contribute to making it simpler for people to comprehend your data, which will make it simpler for both you and them to create useful reports and dashboards.
It is challenging to provide a set of guidelines for what constitutes a good data model because every piece of data is unique and is used in different ways.

A smaller data model is preferable because it will operate more quickly and be easier to use.

"Good intentions and accurate data still aren’t enough. You also need to know that you’ve collected the right data and asked the right questions, and these are both much, much harder than the introductory effective altruist material tends to let on." greeneracresvaluenetwork.wordpress.com/2022/05/28/dai…

Over the past couple of weeks, I have been working on a project where I was required to build a #PowerBI connector for an API.
I have to say, this is an interesting experience, because I was learning a new language in the process. Welcome to the M language.
#DataModeling
🧵
M Language, stands for Data Mashup or Data Modelling language, is a very simple but powerful modelling language.
Basically, M language takes input data, model it, and exports it.
Let's look into the simplest M language "let" block. Image
"Let" is a block used for data modelling. Basically it starts with the famous "let" keyword. Which is similar to "let" in Javascript; it basically defines a variable.
