What is data science

What Is Data Science?

Data science refers to the collection of tools and techniques designed to extract meaningful insights from raw data. It integrates several fields, such as statistics, mathematics, programming, and an understanding of business principles and how they relate to specific industries

In essence, data science can be considered an “umbrella concept” that covers a variety of utilities and processes. Let's look at some related terms to explore this field further.

Data Mining

Data mining refers to the process of extracting potentially valuable information from seemingly chaotic or unstructured data. It involves obtaining raw data, which is then transformed to produce meaningful insights that benefit a brand.

The main phases of this process are as follows:

  • Data collection. In this phase we gather and stores all relevant information in a database. We use various methods including data collection from devices (Internet of Things), web crawling, form generation, API requests, and more.
  • Preprocessing. Once the data is collected, it needs to be prepared in a format suitable for analysis. This is where data science techniques, such as variable discretization, dimensionality reduction, normalization, or quantification, come into play.
  • Algorithm training. As its name suggests, this phase consists of "training" the machine learning algorithm using the collected data. Over time, the algorithm progressively learns to process our data more efficiently to obtain the information we seek.
  • Testing. There are multiple machine learning algorithms available in data science, so the optimal solution can vary. You may need to take some time to determine which best suits your brand's needs. For this reason, experimental trials are essential to make informed decisions.
  • Data visualization and interpretation. Finally, you need to present all the information you have obtained in a visual way, allowing for meaningful conclusions to be drawn. Specialized data visualization tools can be used to effectively communicate and interpret the insights derived from your data.

    Big Data

    The term "big data" refers to the discipline that works with large data sets that may require multiple computers for processing. In data science projects, it's common to encounter large volumes of data, making using this term appropriate. Furthermore, big data represents a significant trend with immense potential in the future, considering the exponential growth of information generated from daily interactions with devices and systems.

    Artificial Intelligence

    In the context of data mining, artificial intelligence plays a crucial role primarily through the application of machine learning algorithms, like decision trees or neural networks. Though artificial intelligence is used in data science, its applications extend far beyond this field.

    Artificial intelligence includes various systems and tools designed to replicate human logical reasoning. This offers numerous possibilities for AI in marketing, including developing chatbots that can interact with customer and optimizing social media advertising strategies.

    Data Scientist

    A data scientist is the professional responsible for designing algorithms used in data mining processes and presenting them in a way that's transparent and relatively easy to interpret. This role requires advanced knowledge of mathematics, computer science, and business.

    Typically, a data scientist collaborates closely with a data engineer, who oversees the IT aspects of the project(s).

    Due to the rapid growth of data science in recent years, it's no surprise that both professions are currently in high demand. As a relatively new field, the market demand for specialized professionals exceeds the current supply, making data science and data engineering highly attractive job opportunities.

    The Benefits of Data Science for Companies

    In today’s marketing landscape, we encounter data from various sources including search advertising, social media, web traffic analytics, display networks, videos, app installs and interactions, websites, CRM, and databases. This data is characterized by its large volumes and ever-increasing speed.

    Effectively analyzing all this and obtaining high-level business intelligence poses a significant challenge. However, by applying data science techniques, you can obtain crucial information that will benefit your brand such as:

    • Predict future user behaviors to make more informed decisions and reduce business risk.
    • Detect anomalies such as cyber-attacks or fraud, which will enable you to take proactive measures to prevent potential losses.
    • Anticipate user needs and personalize offers and content. This personalization increases the chances of conversation, similar to the successful strategies employed by companies like Netflix and Amazon.
    • Designing successful products and establish patterns and trends in consumer preferences. This facilitates designing new products that are likely to succeed in the market.
    • Achieving advanced marketing segmentation and user interaction that was previously impossible.
