What is Data Science Life Cycle? Steps Explained
Major steps involved in the life cycle of Data Science Data are any real or imaginary thing
Data Science is a synthesis of two fields: data and science. Data can be anything real or imagined, and science is the systematic study of the physical and natural worlds. So Data Science is nothing more than the systematic study of data and the derivation of knowledge through the use of testable methodologies to make predictions about the Universe. Simply said, it is the application of science to data of any scale and from any source. Data has evolved into a new fuel that propels enterprises today. That’s why understanding the data science project life cycle is vital. You must be aware of the critical phases as a Data Scientist, Machine Learning Engineer, or Project Manager. A Data Science course will assist you in gaining a firm understanding of the entire data science life cycle.
The major steps in the life cycle of a Data Science project:
1. Problem identification
This is the most important stage of any Data Science endeavor; The first step is to understand how Data Science is useful in the domain under consideration and to identify appropriate tasks that are useful for the same. Domain specialists and data scientists play critical roles in problem identification. The domain expert is well-versed in the application domain and understands the challenge at hand. Data Scientists understand the area and can assist in the discovery of problems and viable solutions.
2. Business Understanding
The business goals are formed by the customer’s need to make predictions, boost sales, minimize losses, or optimize any given process, among other things.
3. Collecting Data:
Data collection is a vital phase since it serves as the foundation for achieving specified business objectives. In general, the information gleaned from surveys is valuable. Data is recorded in various software systems used in the company at various stages, which is vital for understanding the process from product development through deployment and delivery. Historical data from archives is also useful for better understanding the business. Transactional data is also important because it is collected daily. Many statistical tools are used to extract crucial business insights from data. Data plays a crucial part in data science projects.
4. Pre-Processing Data:
Large amounts of data are gathered through archives, everyday transactions, and intermediate records. The data is available in a variety of formats and forms. Some data may also be provided in hard copy format. The information is dispersed among multiple servers. All of this data is extracted, transformed, and processed into a single format. Typically, a data warehouse is built to house the Extract, Transform, and Load (ETL) process or processes. This ETL operation is critical in data science endeavors. In this stage, a data architect is essential because he or she determines the structure of the data warehouse and performs the ETL procedures.
5. Analyzing Data:
Now that the data is available and ready in the required format, the next critical step is to thoroughly grasp the data. This understanding is derived via data analysis utilizing various statistical tools. A data engineer is essential in data analysis. This is also known as exploratory data analysis (EDA). The data is investigated here by creating various statistical functions and identifying dependent and independent variables or features. Data analysis reveals which data or features are essential, as well as the distribution of data. To aid comprehension, various plots are used to show the data. Exploratory Data Analysis and Visualization technologies like Tableau and PowerBI are well-known. Data Science knowledge with Python and R is important for performing EDA on any type of data.
6. Data Modelling:
After the data has been analyzed and visualized, the next critical step is data modeling. The key components are kept in the dataset, and therefore the data gets refined. The crucial thing now is to decide how to model the data. What tasks lend themselves well to modeling Which activities, like classification or regression, are appropriate is determined by the amount of commercial value required. Many modeling options are accessible in these assignments as well. The Machine Learning engineer generates the result by applying various algorithms to the data. Many times, while modeling data, the models are first tested using dummy data that is similar to the actual data.
7. Model Evaluation/ Monitoring:
Because there are numerous methods for modeling data, it is critical to determine which one is most effective. The model is now being tested with real-world data. When there are few data points, the output is monitored for improvement. While the model is being evaluated or tested, data may change, and the output may alter dramatically as a result.
8. Model Training:
The crucial stage is to train the model once the task and model have been determined, as well as the data drift analysis modeling. Training can be done in steps, with the relevant parameters fine-tuned to obtain the needed accuracy. During the production phase, the model is exposed to actual data and its output is monitored.
9. Model Deployment
The model is now exposed to real-time data entering the system, and output is generated. The model can be deployed as a web service, an embedded application in an edge application, or a mobile application. This is a critical phase since the model is now exposed to the real world.
10. Driving insights and generating BI reports
Following model deployment in the real world, the next stage is to determine how the model behaves in a real-life setting. The model is utilized to gain insights that aid in strategic decisions linked to the business. These insights are linked to corporate objectives. Various reports are generated to determine how the firm is progressing. These reports aid in determining whether or not important process indicators are met.
11. Taking a decision based on insight
For data science to work its magic, each of the steps outlined above must be completed meticulously and precisely. When the procedures are followed correctly, the reports generated in the preceding step assist in making crucial decisions for the organization. The insights gained aid in strategic decision making, for example, the business can predict the need for raw materials in advance. Many crucial decisions about business growth and income production can benefit greatly from data science.
