C/C++ SQL/C++/Python which order to learn?

AI Thread Summary
Learning coding for a career in actuarial science or data science involves focusing on several key programming languages. Python is recommended as a starting point due to its versatility and ease of learning. SQL is also essential for database management, as it allows for efficient data querying. While R is beneficial for data analysis, languages like MATLAB and Julia are suggested as alternatives, with free options like Freemat available for beginners. SAS, although still in use, is viewed as outdated and potentially phasing out, making it less favorable for new learners. The discussion emphasizes the importance of aligning language choices with career goals and industry needs, noting that many companies still use SAS due to legacy code despite dissatisfaction with the software. Ultimately, the choice of languages should reflect the specific requirements of the desired job role, with a strong foundation in Excel and Access also being valuable.

Hello everyone,

I am interested in learning coding to be potentially an actuary or data scientist.

Based on my research online, the programs to be proficient at are:

SQL, C++, VBA, Python, VBA, and SAS.

I am sure there are more I should learn but I am pretty much a beginner. In which order should I learn the above programs?

Thanks.

I'd try Python first. Its general purpose and easy to learn.

At the same time you could learn sql as its not a general purpose programming language but rather a database oriented language where a single statement is in fact a program.

As an example, suppose you had a database with a customer table and you wanted to list the customers out in alphabetic order then you might write something like this in SQL:

SQL:
SELECT first_name, last_name, address, city, state
    FROM customer_table
        WHERE city = "Albany" AND  state = "NY"
            ORDER BY last_name, first_name;

As you might guess you'll get a list of names of people who live in Albany, New York in alphabetical order. This of course assumes that there is a customer_table in the database and that it has fields last_name, first_name, city, and state and that the city names are in standard format ie capitalized first letter and the state field uses abbreviations.

Also data science may use R, MATLAB or Julia or even EXCEL in doing their analysis so you have have to be familiar with but not necessarily proficient in many languages used in the data sciences.

You could check out the anaconda distribution of python+julia as a good platform to start with or if you're only interested in Python then you could check out the Processing IDE python mode (comes with graphical examples and is a good way to learn by doing python).

Like jedishrfu, I also recommend to start with Python and R. SAS is really murky and very expensive, too. So as long as you don't plan to become a specialist for phased out software, keep your hands off.

DrDu and jedishrfu thanks for your input.

I am obviously a newbie. So you're saying SAS will become extinct and eventually no longer in use? If so, in how many years?

Also for learning MATLAB you could start with freemat as a free and cheap alternative.

Software goes in and out of favor and there's really no way to say when. You may find a job where the company uses SAS extensively so you go with the flow.

OK. I guess working with SAS is too advanced for me regardless whether it will or will not be phased out.

I will be focusing on Excel/access, R and Python for the next few months.

Matlab and Julia = likely in early 2017

Thanks again jedishrfu
 
I think sas has missed big data. Also, SAS has tried to build up a portfolio of products but with limited success. The point is that Base SAS, though very well tested and therefore used e.g. in pharma industries has never been updated to keep older programs compatible. To make up for this, SAS brought up every couple of years some new, in their eyes "cool" new package, e.g. to make graphics easier, or data bank access, but there is no red line anywhere.
So the situation is such that many enterprises are still using sas because they have lots of code written in it, but no one is really happy with it.

It all depends on what you'd like to do. VBA is strictly for Microsoft Office products, though it can help you learn VB/VB.NET, ASP and ASP.NET as they're all variants of Visual Basic. VBA = Office products, ASP/ASP.NET = websites.

C++ will prepare you for languages based on that (C#, PHP, etc).

It boils down to what your end goal is. SQL queries, while they can become very complex, are generally easy to write as long as you know where the data lies and how to tie what you need together. Another factor is what does the business needs require? For instance, I'm a Database Admin/Developer at my job, but I mainly pull silly reports and data mine all day if I'm not working on a web app, and most of my web apps are just a way to display the queries so people don't keep emailing me to send them an excel report :P
