The Power of Data Lineage: Types, Benefits and Implementation Techniques

0Comments

Businesses heavily rely on accurate and reliable information to make critical decisions. However with data flowing from various sources and undergoing transformations, ensuring its quality can be a challenge. This is where data lineage comes in.

What is Data Lineage?

Data lineage can be thought of as the DNA of data. It’s a blueprint that illustrates the journey of data from its origin to its destination, detailing every transformation and interaction along the way. Data lineage can be called as a process of tracking the journey of data – from its origin to its final destination. It provides a clear picture of where the data comes from, what transformations it undergoes, and where it ends up. This includes:

  • Source: Identifying the initial source of the data, such as a customer relationship management (CRM) system, a sensor, or a social media platform.
  • Transformations: Tracking any changes made to the data during its journey, like filtering, aggregation, or calculations.
  • Destination: Understanding where the data is ultimately used, such as a data warehouse, an analytics application, or a reporting tool.

Types of Data Lineage:

Here are different types of data lineage:

  1. End-to-End Lineage: This provides a macro view, tracking data from inception to its final form. It covers every system and processes the data goes through, essential for compliance requirements and overall data governance.
  2. Source-to-Target Lineage: This focuses on documenting and understanding the journey of data from its source (origin) to its target (destination), including all transformations and processes

Why is Data Lineage Important?

Data lineage offers several benefits for organisations:

  • Improved Data Quality: By understanding the data’s flow, you can identify potential errors or inconsistencies at their source. This helps ensure the accuracy and reliability of your data analysis.
  • Efficient Troubleshooting: When issues arise in your data pipelines, data lineage allows you to quickly pinpoint the root cause, saving time and resources in debugging.
  • Enhanced Data Governance: Data lineage provides an audit trail for your data, making it easier to comply with regulations and data privacy requirements.
  • Effective Impact Analysis: When considering changes to your data pipelines, data lineage helps you understand the downstream impacts, minimising the risk of unintended consequences.

How to Implement Data Lineage

There are several ways to implement data lineage in your organization. Some of them are mentioned below:

  • Automated Tools: Data lineage tools can automatically capture and track data flows, providing a visual representation of the data journey.
  • Manual Documentation: While less efficient, data lineage can be documented manually through process flows and data dictionaries.
  • Data Catalogs: Centralized data catalogues can store information about data sources, transformations, and destinations, aiding in data lineage efforts.

In today’s data-rich world, data lineage is no longer a luxury, but a necessity. Remember, data lineage isn’t just a technical concept; it’s essential for data quality, governance, and compliance. By understanding where data comes from and how it transforms, organisations can make informed decisions and ensure accurate data usage.

Data lineage is a powerful tool for organisations that rely on data-driven decision-making. By understanding the flow of your data, you can ensure its quality, improve troubleshooting efficiency, and gain a deeper understanding of your data ecosystem.

Today when data is the new fuel, analysing and understanding the power of data plays a crucial role in running a business successfully. Data analysis can take us to a place where we know exactly about the performance of the businesses and improves the decision-making for future activities. Nowadays, there are various ways we have found to utilise the data for betterment, and data analysis is one of them.

There are various types of data analysis we use at different levels, but at a broader level, we divide them into four categories. However, these data analysis categories are connected, or we can say that they are built upon each other. The complexity and resources required also increase as we go deeper into any data analysis process. At the same time, we also get more insights and values from the process. So let’s take a deep dive into the types of data analysis.

The four types of data analysis are:

  • Descriptive Analysis
  • Diagnostic Analysis
  • Predictive Analysis
  • Prescriptive Analysis

Let’s introduce each type of analysis, and their business uses individually.

Descriptive Data Analysis

We can consider this type of data analysis as the explainer of data, and it is one of the simpler and most common types of data analysis which businesses are using today. Talking in deep descriptive data analysis tells about what happened in the past and usually combines dashboards and graphs with it.

One of the most significant uses of descriptive analysis is to keep track of KPIs(Key Performance Indicators). KPIs tell us about business performance based on predefined benchmarks.

Some examples of Business applications of descriptive data analysis are:

  • Sales Analysis
  • Customer Segmentation
  • Financial Analysis
  • Operations Analysis
  • Market Research

Overall, descriptive data analysis can help businesses to make informed decisions, optimise their operations, and gain a competitive edge in their industry.

Diagnostic Data Analysis

After performing the descriptive analysis and getting to know what happened, one must look forward to seeking why it happened, and this is where diagnostic data analysis comes to help.

We perform diagnostic data analysis to find the cause of output from the descriptive analysis. It is again a common type of data analytics as it establishes connections between the data points and provides the pattern of behaviour.

Identifying anomalies, Hypothesis testing, data mining, and root cause analysis are some of the critical aspects of diagnostic data analysis.

Diagnostic data analysis is an essential tool for businesses that are looking to understand and address complex issues or problems. By identifying the root cause of a problem, businesses can develop more effective solutions and prevent the issue from recurring in the future.

Some examples of Business applications of diagnostic data analysis are:

  • Quality Control
  • Customer Churn
  • Employee Turnover
  • Marketing Effectiveness
  • Supply Chain Optimization

Overall, diagnostic data analysis is an important tool for businesses that are looking to improve their operations and address complex issues.

Predictive Data Analysis

After knowing and understanding what happened and the root cause of what happened, one needs to answer the question of what is likely to happen. Predictive analysis is used to predict future outcomes using the previous data.

We can think of it as the next step to take after diagnostic analysis that uses the past summarised data to make predictions of the outcomes of different events. However, in this type of analysis, we majorly perform statistical modelling, which needs technology with manpower to predict. Before applying predictive data analytics to any system, it is important to know results from this analysis are just an estimation, and their accuracy depends on the quality of the data and modelling.

While the above-discussed analysis is common in many businesses, predictive analysis is where many organisations face many difficulties. Many organisation has the potential data, but they lag in skills and manpower to apply predictive analysis. However, there are many Business applications of predictive data analysis:

  • Demand Forecasting
  • Fraud Detection
  • Risk Management
  • Workforce planning

This analysis plays an important role in making informed decisions. By being informed about future trends and events, businesses can optimise their operations more accurately and improve their bottom line, and gain a competitive edge in their industry.

Prescriptive Data Analysis

Here, the final type of data analysis is prescriptive data analysis, which goes beyond descriptive and predictive analysis by recommending a course of action based on the analysis results. This approach uses machine learning algorithms and other techniques to analyse data and provide decision-makers with actionable insights.

In the very basic, it combines data from various sources (historical, real-time, future) to determine patterns and relationships. It can be automated and involves simulations and optimisation techniques to determine the best course of action for a particular scenario. There are many different fields like healthcare, finance, and manufacturing where this analysis is involved and helps in optimising operations, pricing strategies, and marketing campaigns.

The application of prescriptive data analytics includes

  • Supply chain optimization
  • Fraud detection and prevention
  • Customer service
  • Energy management

However, When we look across various industries, only a few organisations are truly able to implement it. We can consider it as the frontier of data analysis because it combines results from all previously explained types of data analysis, different tools and technologies, which makes it most complex to implement.

Conclusion

The different types of data analysis — descriptive, diagnostic, predictive, and prescriptive — are interconnected and rely on each other to varying degrees. While each type serves a unique purpose and provides valuable insights, moving from descriptive and diagnostic analysis to predictive and prescriptive analysis requires greater technical ability. However, it also unlocks deeper and more valuable insights for your organisation. By leveraging predictive and prescriptive analysis, you can gain a greater understanding of trends and patterns, make more accurate predictions, and ultimately make better decisions that drive growth and success.

As the name suggests, data science synthesises data and science. In the more basic form, we can say that data science is a field that enables us to study data and derive knowledge through it systematically. In between this process, we use some tested methodologies to make predictions about the future and behaviour of the universe. Because of the evolution of this field, data has evolved as the new fuel using which organisations are propelling.

Currently, the field of data science is witnessing various changes aimed at making it more accurate and valuable. Despite these changes, one thing that remains constant is the life cycle of a data science project. Although the life cycle may seem simple, implementing it in real-life scenarios can be challenging. Therefore, knowing the potential difficulties before applying AI and data science use cases in any field is important. This article aims to create awareness of the steps to be followed when implementing a data science project. So, let’s delve into the topic by exploring these general steps.

Steps in the life cycle of a data science project:

1. Problem identification

This step in the life cycle of a data science project is the most important step because from here lets data scientists know the importance of data science in the domain and the importance of the task we are going to solve using data science. However, a domain specialist and a data scientist play a crucial role in this step where the domain expert understands the domain and the challenge data science will solve; on the other hand, a data scientist understands the data using which he or she can assist in exploring the problem and its viable solution.

2. Business understanding

Generally, the business goals are generated by the needs of the customer and examples of such goals are making predictions of sales, boosting the sale, minimising loss, or optimising any procedure etc.

3. Data collection and preparation

One thing that we should consider here is that the foundation of any data science project is the data. Generally, we can see there are various types of data we can gather from various sources. Understating a data source and extracting data in the right format and quality is an important task to perform. There can be many kinds of data but mostly historical data we use to understand the business and transaction data lead our understanding toward knowing trends. We can use various statistical tools to crucial business insights from data.

4. Pre-Processing Data

When we have data to perform the required task, it is necessary to transform the data according to the requirement. There are huge chances of data being in a variety of formats and forms. Also, some of the data can be provided in hard copy format. So data science project gets data from dispersed servers or sources. This data needs to be extracted, transformed and processed in such a way that they all can become single-formatted. Generally, we call this step an ETL(extract, transform and Load) process. This ETL process is one of the critical processes in the life cycle of data science projects. Here a data architect is required to facilitate the project, from warehousing the data to performing the ETL process.

5. Analysing Data

After making the data right and single format, the next step in the life of a data science project is to understand and find insights into the data; it is just like knowing the data and can be done by analysing the data. Here also, many statistical tools are required, and we can also say this step is EDA(exploratory data analysis). Using these statistical tools, we investigate the data and identify the patterns, variables (dependent and independent), and data distribution. To aid a more accurate view of data, we make various plots using the data. Tools like Tableau and PowerBI are well-known for finding insights, and Python and R programming languages play an important role in performing statistical EDA on any data type.

6. Data modelling

After we know the maximum about the data, data modelling takes part in this cycle. As we know, the key components rely on the data. Therefore, data gets refined. Here the first crucial thing is understanding and deciding how to model the data. However, we also need to know which task is required to perform on data, and overall tasks can be divided into four categories: regression, classification, clustering, and dimensional reduction. Many modelling options are accessible, and This list of articles will tell about the different models we use for data modelling and how we can use them.

Here machine learning engineers apply different models and choose an optimal model to use with the data. To test this model engineer uses different methods and matrixes on dummy data, which is either a part of the actual dataset or a replica of the data we are using for data modelling.

7. Model Evaluation/ Monitoring

In the above, we have seen that there are various options available for modelling data, so it becomes critical to determine the one effective way of modelling data. This step helps in knowing how the data modelling is performed in the real world. When modelling data using a few data points, there is a probability of alteration n the output of the data. So this model monitoring helps in model improvement where we evaluate and change the data and try to obtain a highly accurate model.

8. Model Training

This is a crucial stage of this life cycle as it trains the model that ML engineers have determined in the early stages. This stage trains the selected model on selected data and helps in data drift analysis. Training can be done in steps where first relevant parameters are fine-tuned, and data goes through these parameters to obtain the needed accuracy. This is done production, and the model is exposed to the selected data and output is monitored again.

9. Model Training

Now, it’s time to expose the model in real-time while maintaining the data flow through the system. There are various ways to deploy the model, like deploying it as a web service embedded in an edge application. This step is a crucial one because here, the real world sees the model working here.

10. Collecting insights and driving BI reports

This step gives information about the behaviour of the model in a real-life setting. Here we use the model to gain insights that lead to strategic business decisions. Usually, these insights help in completing corporate objectives, where we get information like the progress report of the firm, important process indicators that are met or not and so on.

11. Decision Making

In order to leverage the optimum of data science, it is essential to meticulously and precisely execute each step of the process outlined above. By following these procedures correctly, the generated reports can assist organisations in making crucial decisions that can significantly impact their operations. With the insights gained from data science, businesses can make informed strategic decisions, such as predicting the need for future sales reports in advance. By utilising data science, organisations can greatly benefit from making critical business growth and revenue generation decisions.

Conclusion

Here in the above, we have discussed the steps in the life cycle of a data science project, and we got to know it includes not only technical steps to be followed but also includes many managerial steps. These steps are crucial to be performed because it helps unleash the full potential of data science and artificial intelligence.
