Data Science: Definition, Tools Used, and Its Application

Data Science – Today, data science is an important part of various industries. This is because the large amount of data generated is a hot topic of discussion and debate in IT circles. Over the years, the popularity of data science has grown and many companies have started to create specific techniques for data science in order to grow their business.

Sinaumed’s, in this sinaumedia article, we will learn the basics of data science. Let’s also learn what to do to become a data scientist in the future!

Definition of Data Science

Data science, aka data science , is a focus of study that deals with large volumes of data using modern techniques to find invisible patterns, gain meaningful information, and make business decisions with that information.

Complex machine learning algorithms are used in data science to build predictive models. Meanwhile, the data used for analysis can come from various sources and appear in various formats.

Data science includes a topic of discussion that is really broad and with a strong subjectivity. Data science itself, by definition, is not a science that stands alone. It is a combination of various fields, especially mathematics, computer science, business strategy, to statistics.

There are three components involved in data science, namely organizing, packaging, and delivering data or The OPD of Data. For organizing the data itself is the process of storing data which is then combined with data management.

Meanwhile, data packaging is the process of manipulating and merging various raw data that will be presented later. Furthermore, delivering data is the process of ensuring that messages in data have been accessed by those who need them.

In 2011, there was research that resulted in a prediction that the world would produce more data in 2020. Now, what does Sinaumed’s think?

With this drastic increase in data flow, new tools that can be used to make the right use of raw data will emerge. The scope of data science itself is tools, techniques, to technology that will help us deal with the increasing flow of data itself.

It is an interdisciplinary blend of data derivation, algorithm development and technology to solve very, very complex analytical problems.

Tools used

Do you understand what data science is ? Next, we also need to understand the tools used in data science in general. They are none other than Big Data, Machine Learning, Data Mining, Deep Learning, to Artificial Intelligence.

The following is a discussion of each:

1. Big Data

Big Data is the first tool we have to cover. A new data scientist can help predict products that will be sold, predict when and why customers change operators, to understand how good their customers are driving, unit deployment, and so on for product companies, telecommunications, to car insurance, only if Big Data is used .

2. Machine Learning

Machine Learning is the second tool. This tool is interdisciplinary in nature and uses techniques from the fields of statistics, computer science, and Artificial Intelligence. The main component of Machine Learning is an algorithm that can automatically learn from experience to improve its performance. In various fields, the algorithm itself is used.

3. Data Mining

Data Mining as the next tool discussed, is the application of a special algorithm to extract patterns from a data set. Data Mining is closely related to Machine Learning in terms of extracting informative patterns stored in data sets.

4. Deep Learning

Next, there are Deep Learning tools . Not just “study deep or seriously” as we can do when we are about to take an exam, this new term that is often used and discussed refers to the process of applying Deep Neural Network technology which is a neural network architecture and hidden layers to solve problems.

5. Artificial Intelligence

The last data science tool is Artificial Intelligence . The term commonly referred to as AI is a field of computer science that emphasizes the creation of intelligent machines that can react and work like humans. Meanwhile, AI has a core component in the form of computer programming for certain characteristics, such as reasoning, knowledge, perception, problem solving, learning, planning, and so on.

Data Science Life Cycle

Now that we’ve finally identified the tools commonly used in data science , let’s focus on the life cycle of data science itself. This cycle consists of five different stages, each of which has its own task.

1. Catch

Data Acquisition, Data Entry, Signal Receiving and Data Extraction. This stage involves collecting raw data, both structured and unstructured.

2. Maintain

Data Warehousing, Data Cleaning, Data Staging, Data Processing and Data Architecture. This one stage involves taking the raw data and putting it in a form that we can use.

3. Process

Data Mining, Clustering/Classification, Data Modeling, and Data Summarization. The data scientist will take the prepared data and examine patterns, ranges, and generally to determine the usefulness of the data in predictive analysis.

4. Analysis

Exploratory/Confirmatory, Predictive Analysis, Regression, Text Mining and Qualitative Analysis. This is the essence of the data science life cycle actually. This stage involves applying various analyzes to the existing data.

5. Communicate

Data Reporting, Data Visualization, Business Intelligence, to Decision Making. In this step, the analyst will prepare the analysis in an easy-to-read form. Examples include charts, graphs, and reports.

Requirements in Data Science

In this sub-chapter, we will study some of the technical terms or concepts that must be known before starting to study data science itself. Let’s see!

1. Machine Learning

As with Machine Learning in data science tools , machine learning itself is indeed the backbone for a data scientist. The reason is, he must have a strong understanding of this field, in addition to basic knowledge of statistics.

2. Modeling

We can make calculations and predictions quickly and precisely based on what we already know about data, thanks to mathematical models. Modeling itself is also part of Machine Learning and involves identifying the most suitable algorithm to solve the existing problem and training the model itself.

3. Statistics

The essence of data science is statistics. It will help us to extract more knowledge and get more meaningful results with robust statistics.

4. Programming

Some level of programming is required to run a successful data science project. Generally, the programming language is Python, and it is very popular because it is easy to learn and supports a lot of data science and machine learning literature.

5. Databases

It is necessary to understand how databases work, management and how to extract data from databases to become a capable data scientist .

Example of Application of Data Science

We need to know more about data science, especially after understanding the tools, cycles, and various requirements to learn it. Various fields: such as social, journalism, finance, and others use or apply data science . Examples of its application can also be seen in the processing of Natural Language and Machine Learning in news articles to identify zoning reforms.

The Metropolitan Urban Community and Housing Policy Center also has data scientists who want to estimate the impact of zoning reforms on the housing supply in the United States (US) metropolitan area. In this case, the data scientist uses data from around 2000 local news sources to identify local reforms because it is impossible for them to get historical data from thousands of municipalities in the metro area.

They can also flag articles that mention major reforms and add relevant metadata similar to whether the article mentions parking, height limits, or other characteristics with the application of Natural Language and Machine Learning processing .

Data scientists also collect data by type using this method. Copying court records to inform criminal background check policies is another example of data science application . Data scientists from the Center for Judicial Policy wanted an estimate of the number of people with likely criminal records in Washington DC

They also worked with the Researcher team to collect data through online searches of the Washington Superior Court. The data is then used by the data scientist to create statistics on the criminal background of the community in the area.

What Do D ata Scientists Do ?

We already know what data science is , and must be wondering what this job role actually looks like: here’s the answer. A data scientist analyzes business data to extract meaningful insights. In other words, a data scientist solves a business problem through a series of steps, including:

  • Before tackling data collection and analysis, they define the problem by asking the right questions and gaining insight.
  • They then determine the correct set of variables and data set.
  • They collect structured and unstructured data from many different sources, such as company data, public data, and others.
  • Once the data is collected, they process the raw data and convert it into a format suitable for analysis. This involves cleaning and validating data to ensure uniformity, completeness and accuracy.
  • After the data is rendered into a usable form, it is fed into an analytical system: Machine Learning algorithms or statistical models. This is where data scientists analyze and identify patterns and trends.
  • When the data has been fully rendered, they interpret the data to find opportunities and solutions.
  • They complete tasks by preparing results and insights to share with appropriate stakeholders and communicating the results.

Data Science Oversight

Who oversees the data science process ?

1. Business Manager

The business manager is the person in charge of overseeing data science training methods . Their primary responsibility is to collaborate with the data science team to characterize problems and define analytical methods.

A data scientist can oversee a marketing, finance, or sales department, and report to an executive in charge of that department. Their aim is to ensure projects are completed on time by collaborating closely with data scientists and IT managers.

2. IT Manager

Next, the IT manager. If members have been in the organization for a long time, responsibilities will definitely be more important than others. They are primarily responsible for developing the infrastructure and architecture to enable data science activities .

Data science teams are continuously monitored and appropriately resourced to ensure that they are operating efficiently and securely. They may also be responsible for creating and maintaining the IT environment for the data science team .

3. Data Science Manager

The data science manager is the last part. They primarily track and oversee the work procedures of all team members. They also manage and track the day-to-day activities of the three data science teams . They are team builders who can combine project planning and monitoring with team growth.

The Importance of Learning Data Science

Data is an important element for any industry to make decisions. Moreover, in the all-digital era alias all-technology like now. Even so, an analytical process is needed, such as collecting, tidying up, and analyzing it to make the data useful information.

Of course, this process is not easy because there is a large and growing amount of data that must be collected and analyzed. That is the reason for the growing demand for jobs in data science , especially by start-up companies. In fact, don’t be surprised if the government also needs data science to regulate accurate policies.

Learning data science is also a high-value investment to deal with trends in this digital era. We will be able to analyze data anywhere, have good problem solving skills, to skills in other fields of science with the data science competencies we have.

For example, a profession engaged in the data sector is required to always adapt to constantly changing trends, namely data scientists . By studying it, we are expected to be able to keep up with the current changes.

If Sinaumed’s is interested in focusing on pursuing a career in this field, such as becoming a data analyst, data scientist, to data engineer , there are actually several things that must be prepared in order to become a reliable data expert. This, one of them is programming which is the main thing in managing data.

In addition, we are also required to be able to use certain software , such as Microsoft Excel, SPSS, and so on to perform data analysis. Not only using the software , Sinaumed’s must also understand programming languages ​​such as R and Python which will definitely be a plus if Sinaumed’s wants to have a career in this field.

Because data science is closely related to data (as mentioned above), an understanding of statistics and mathematics must also be well mastered. This is because the results of successfully processed data will of course be presented to other parties, not all of whom understand data science terms .

For this reason, these skills will be very useful in this regard, including good communication and visualization so that our presentations can be more easily understood by ordinary people.
