Processes in Data Analytics vs. Data Science:

Data Analytics Process:

1. Define Requirements: Determine the data needed to solve specific problems.
2. Integrate and Manage Data: Process and clean datasets for analysis.
3. Analyze Data: Apply statistical tools to identify trends and insights.
4. Share Insights: Present findings through reports and dashboards.

Data Science Process:

1. Goal Definition: Collaborate with stakeholders to set objectives.
2. Data Collection: Design systems for gathering structured and unstructured data.
3. Exploration: Analyze data using machine learning and advanced techniques.
4. Model Building: Develop algorithms to address complex challenges.
5. Insights Deployment: Share findings to guide strategic decisions.

The process of data analytics involves defining requirements, integrating and managing the data, analysing the data, and sharing the insights. Data analysts prepare, manage, and analyse well-defined datasets to identify trends and create visual presentations to help organisations make better, data-driven decisions.

The process of data science involves several stages, starting from goal definition to model deployment and presentation. The data scientist works closely with business stakeholders to define goals and objectives for the analysis. Post this, they design and implement data collection systems, followed by investigating and exploring the data. They then choose one or more potential analytical models and algorithms and build these models. Once the models are refined, they are run using the available data to produce insights, which are then shared with all stakeholders.
