Basic Principle of Data Science Life Cycle
Data science unites the concepts of science with data. Data can be anything, actual or imagined, and science is nothing more than the systematic study of the natural and physical worlds. Data science is simply the systematic study of data and the development of knowledge using verifiable methodologies to make predictions about the universe. Simply said, it involves applying science to data from any source and size. Today’s enterprises are powered by data, which has replaced oil. Understanding the data science project life cycle is essential for this reason. You need to be aware of the critical processes, whether you’re a project manager, data scientist, or engineer specializing in machine learning. The entire data science lifecycle can be easily understood with the help of a Data Science course.
What is a Data Science Life Cycle?
A data science lifecycle indicates the iterative procedures required to develop, produce, and maintain any data science product. Since no two data science projects are created equally, so does their life cycle. However, a broad lifecycle incorporating some of the most typical data science activities is still imaginable. Machine learning algorithms and statistical techniques are used to produce improved prediction models in a comprehensive data science lifecycle process. The process involves several common data science steps, including data extraction, preparation, cleaning, modeling, and evaluation. This broad procedure is known as the “Cross Industry Standard Process for Data Mining” in data science.
In the following write-up, we’ll go through each of these steps in detail so you can see how organizations use them in data science initiatives. Before that, though, let’s take a closer look at the data scientists that work on each project.
Who Are Involved in The Projects?
Data science projects are used in various real-world fields or businesses, including banking, healthcare, the petroleum industry, and others. An individual who has worked in a specific subject and is an expert in it is referred to as a domain expert.
A business analyst is needed to understand the chosen area’s business requirements. The person can assist in coming up with the best solution and a schedule for it.
A data scientist has expertise working with data, is a specialist in data science initiatives, and can determine what data is necessary to accomplish the desired result.
Machine Learning Engineer:
A machine learning engineer can offer guidance on the model to obtain the desired output and come up with a strategy to generate the accurate and necessary output.
Data Engineer and Architect:
The professionals in data modeling are data architects and data engineers. They take care of data visualization for improved comprehension, data storage, and quick retrieval.
How Many Kinds of Data Science Projects
Data Science projects follow the following major steps:
1. Problem Identification
In any Data Science project, this is the most crucial step. The first step is to comprehend how Data Science is useful in the domain under consideration and to identify relevant jobs that are helpful for the same. Data scientists and domain experts are crucial players in identifying problems. A domain specialist is well-versed in the application domain and the specific issue. Data scientists are knowledgeable and may identify problems and suggest potential solutions.
2. Business Understanding
Business understanding is the only thing that can be used to determine what a customer truly wants. The objectives of the business are determined by the customers, who may desire to make predictions, increase sales, reduce losses, or optimize a particular process, among other things. To comprehend business, two crucial actions are taken:
3. KPI (Key Performance Indicator)
Key performance indicators determine the performance or success of any data science project. The customer and the data science project team must understand the business-related KPIs and related data science project objectives. The data science project team determines the goals and indicators after developing the business indicators following the business need. Let’s look at an example to help us better comprehend this. The purpose of data science is to use the current resources to manage twice as many clients if the business need is, for example, to optimize the company’s overall spending. Defining the key performance indicators for any data science project is essential because the cost of the solutions will vary depending on the project’s goals.
4. SLA (Service Level Agreement)
After the performance indicators have been determined, finalizing the service level agreement is crucial. The service level agreement terms are chosen based on the company objectives. Similarly, all airline reservation systems must be capable of handling 1000 passengers at once. The service level agreement stipulates that the product must meet these service criteria.
The project moves on to the following key phase once the service level agreement and performance indicators are finalized.
5. Collecting Data
Data collection is crucial because it serves as the foundation for achieving specific business objectives. The system will receive data in various ways, including surveys, social media, archives, enterprise data, and statistical techniques.
Large amounts of information come from archives, regular transactions, and intermediate records. The data comes in a wide variety of formats and types. The data is dispersed over numerous servers in various locations. These data are all extracted, put into a single format, and processed after that. Typically, the Extract, Transform, and Load (ETL) process or processes are carried out as the data warehouse is built. The data science effort relies heavily on this ETL procedure. A data architect’s job at this stage is crucial since they determine the data warehouse’s structure and carry out the ETL procedures.
The success of data science in numerous applications has made it the rage right now. Everyone is profiting from data science, from the petroleum industry to the retail sector. Business expansion is facilitated by thoroughly understanding the data science life cycle and effectively using the abovementioned phases. Numerous technologies are available to draw insights from the data, which can subsequently be used to enhance business. Stay tuned for more information!
