How Business Intelligence is Making the World a Better Place

What is Business Intelligence(BI)?

In general, BI refers to that companies slice and dice data to look for patterns. Then they make business decisions by the data insights.

When I ask other people this question: Do you know what is Business Intelligence?

I usually got the answer “No”.

However, I found most of people know what is Big Data. Of course, this is a buzzword.

Even those people who are not familiar with this area, they can tell me Big Data means the data is big…

This is a good thing. Even sometimes our understanding for terms is not precise.

It is common because a glossary consists of many knowledge systems.

It is hard to explain it in one sentence.

For example, Business Intelligence is a professional area, including ETL, Data Warehousing, etc. You can’t explain all of them to others.

Simply, BI is a pipeline which can transform data into information and then it creates business value.

How can we create business value using BI?

Reporting, which is common in New Zealand.

Reporting means using data visualisation techniques to visualise company’s business data.

It mainly focuses on finance, supply chain, marketing and human source departments.

For example, sales and marketing department cares about sales amount, order quantity, return rate, etc.

Then BI can be used to filter and extract analysis results. Tables and figures differ according to their subjects and they relate to each other.

Analysis about “abnormal” data.

Through data visualisation results, the abnormal data means some data indicators are beyond our predictions.

Sometimes it is positive that we are pursuing.

For example, average user registration amount is 1000 per month.

However, we find one month the number reaches 3000.

It is a kind of positive abnormality. Of course, sometimes the abnormal data can be negative.

We can analyse which factor contributes to the abnormality through one or more dimensions data tables and figures.

Those results can help to make better business plans.

Conclusions:

BI is actually a business and management area.

It comes from the presentation of visual analysis reports. Then it tries to find business problems (positive or negative) to improve business operations.

BI jobs in New Zealand:

According to Business Analyst on careernz website, BI analyst is in high demand and its salary is $81K-$104K per year.

Many companies hire BI analysts in New Zealand, including:

  1. Government departments or tertiary universities/institutes
  2. Finance companies
  3. Marketing companies
  4. Professional firms such as law and accounting

Next blog I will talk about which techniques are popular in New Zealand and how to learn them.

How I Join Business Intelligence / Data Analysis Career(Academia)

Before February 2018: My Bachelor Degree

After I completed my bachelor degree of Information Security in Xidian University and experience in Huawei, I start to look for a new challenge.

Then I came to New Zealand to study the Master of Computer and Information Sciences in AUT.

February 2018 – July 2018: Selected Courses

In the first semester of my master degree, I enrolled in two papers: Data Mining and Machine Learning, Natural Language Processing.

The two courses have assisted me in broadening my knowledge while showing me the diverse research side of Computer Sciences, especially Machine Learning and Artificial Intelligence.

July 2018 – December 2018: Master Thesis

Then I enrolled in the 120 points thesis in the second semester.

The thesis research of my Master degree is totally a different challenge to me.

It differs from previous teaching courses because its requirements of the abilities of critical thinking and problem-solving are much stricter.

Moreover, research is also an iterative procedure, so patience and persistence are also essential when it comes with persistent failure.

Luckily, I met my primary supervisor and second supervisor, who guided and helped me a lot.

In 14th November (my birthday day) last year, my primary supervisor suggested me to apply for the Summer Research Award at AUT, which can further augment to my capabilities.

Summer Research Award is awarded to students who have got satisfactory results in the three-month project in AUT. The evaluation is based on the final data analysis report. Only 10 students in the Faculty of Computer Sciences can get the award.

December 2018 – February 2019: Summer Research Award

Then I applied for it and my proposal got approved.

Through three months, I successfully classified and achieved a 92% accuracy result by building a neural network model in this project.

In the last week of February this year, I developed creative contents as academic reports with online LaTeX Editor (Overleaf) to get my final payment.

I recommend the Summer Research Award in AUT, because not only it can bring you some extra gains and honour, but also it can offer you an opportunity to gain some practical skills.

The most important thing is that I start to realise I am more interested in practical industry rather than academia!

Attachment is the Summer Research Award I gained.

February 2019 – July 2019: Two Publications

I also developed my research and analytical skills while publishing two papers

  • “An automated privacy information detection approach for protecting individual online social network users” to the Japanese Society of Artificial Intelligence (JSAI) journal
  • “Privacy Information Classification: A Hybrid Approach” to The 4th International Workshop on Smart Simulation and Modelling for Complex Systems (SSMCS 2019)

Maybe some people think I should take a PhD degree to enhance my research skills. However, I am not interested in academia any more.

New Journey:

It is time for me to continue my journey and gain more experience in the industry of Business Intelligence and Data Science industry!
