Unlocking Revenue: Mastering Data Practices for Business Growth

Business

The Cost of Bad Data Practices

A recent report by commercial data and analytics firm Dun and Bradstreet reveals that businesses are missing out on revenue opportunities and losing customers due to ineffective data practices. The research, based on a survey of 510 business decision makers in the US and UK, highlights the significant impact of poor data management on various aspects of business operations.

Customer Retention and Acquisition

Nearly 20% of companies have lost a customer due to using incomplete or inaccurate information about them, while an additional 15% failed to sign a new contract with a customer for the same reason

These findings underscore the importance of maintaining accurate and comprehensive customer data to ensure customer satisfaction and retention.

Financial Forecasting and Credit Management

The report also found that nearly one-quarter of respondents had inaccurate financial forecasts, while 17% offered too much credit to a customer due to a lack of information, resulting in financial losses

Accurate data is crucial for making informed decisions and mitigating financial risks.

Compliance Challenges

The survey revealed stark discrepancies between the US and UK, with compliance being nearly twice as big a concern in the UK, likely due to the challenges of meeting the requirements of the General Data Protection Regulation (GDPR)

More than 10% of organizations reported being fined for data issues related to compliance

Barriers to Effective Data Utilization

The way data is structured appears to be a significant barrier at many organizations. Nearly half of the respondents (46%) said data is too siloed to make any sense of it

The biggest challenges to making use of data are protecting data privacy (34%), having accurate data (26%), and analyzing/processing data (24%)

The Need for Data Governance and Stewardship

The lack of structure in data management might reflect the fact that 41% of business leaders said no one in their organization is responsible for data management

The absence of ownership could also explain why more than half of the surveyed organizations have not had the budget needed to implement effective data management practices

Monica Richter, chief data officer at Dun and Bradstreet, emphasizes the importance of making data governance and stewardship a priority, stating that clean, defined data is key to the success of any program and essential for mitigating risk and growing the business

Business

The Future of Data Management

The survey indicates a growing recognition that responsibility for data should be a priority for C-level executives

However, business leaders are divided as to who on the leadership team actually owns responsibility for data and how that might change in the future

All business leaders agreed that the CEO has ultimate responsibility for data, more so than even technology leaders such as the CTO or CIO

A majority of organizations acknowledged that data will be vital to their future success

However, fewer than one quarter of them said they have employees dedicated to data management or the right talent to implement effective data management practices

In conclusion, the report underscores the profound effect that poor data practices can have on business performance, emphasizing the urgent necessity for companies to prioritize data governance and stewardship. Neglecting these areas can lead to missed opportunities, inefficient processes, and heightened risks.

Data silos, where information is fragmented across different departments, often hinder collaboration and lead to inconsistent insights, making it difficult for businesses to make informed, data-driven decisions. Inaccuracies within data can distort key metrics, resulting in misguided strategies that affect revenue, customer satisfaction, and operational efficiency. Additionally, the lack of clear data ownership leaves companies vulnerable to regulatory non-compliance and cybersecurity risks.

By focusing on breaking down data silos, enhancing data accuracy, and establishing clear accountability, businesses can unlock new revenue streams through deeper insights into customer behavior, better anticipate market trends, and optimize operational processes. Furthermore, improving data governance ensures that the organization remains compliant with evolving data regulations, avoiding costly penalties and reputational damage.

Ultimately, companies that adopt robust data governance and stewardship practices are not only better positioned to enhance customer retention and satisfaction but are also more likely to drive innovation and maintain a competitive edge in an increasingly data-centric business environment.

Transforming Data Integration: The Shift from ETL to ELT in the Cloud Era

Data integration

What You’ll Learn in This Blog

  1. The difference between ETL and ELT
  2. The benefits of using an ELT over ETL or “hand-cranked” code
  3. How the Cloud, with the next generation of tools, can simplify the data integration landscape
  4. Key data integration terms

ETL vs ELT

Let’s start by understanding the difference between ETL (Extract, Transform, Load) and ELT (Extract, Load, Transform).

ETL

ETL emerged in the 90s with the rise of data warehousing. The process involved:

  1. Extracting data from source systems
  2. Transforming the data integration process
  3. Loading the transformed data into a database for analysis and reporting

Before ETL tools existed, this was done using hand-coded scripts, which was time-consuming and lacked lineage and maintainability. ETL tools like OWB, DataStage, and Informatica simplified the process by performing transformations on application servers rather than source systems or target databases.

The benefits of ETL tools include:

  • Lineage tracking
  • Logging and metadata
  • Simplified slowly changing dimensions (SCD)
  • Graphical user interface (GUI)
  • Improved collaboration between business and IT1

ELT

ELT tools leverage the power of the underlying data warehouse by performing transformations within the database itself. This minimizes the need for excessive data movement and reduces the latency that typically accompanies traditional ETL processes.

With the rise of Hadoop during the “Big Data” era, computation was pushed closer to the data, leading to a more siloed approach between traditional data warehouses and big data systems. This shift increased the need for specialized programming skills, complicating data accuracy, lineage tracking, and overall management in complex environments.

The Next Generation of ELT Tools

Cloud-based data warehouses like Snowflake, Google BigQuery, and AWS Redshift have enabled the resurgence of ELT. Next-generation ELT tools like Matillion fully utilize the underlying cloud databases for computations, eliminating the need for data to leave the database.

Modern analytical platforms like Snowflake can satisfy both data lake and enterprise data warehouse requirements, allowing the use of a single ELT tool for transformations. This reduces the total cost of ownership (TCO) and development time while improving maintainability and impact assessment.

Streaming and Governance

Streaming enables real-time analytics by combining data sources to help businesses make quick decisions. Tools like HVR can replicate data cost-effectively, blending replication with ELT (RLT).

Governance is crucial for ensuring data lineage, metadata, audit, and log information, especially for compliance with regulations like GDPR. ELT tools like Matillion provide this information easily through their GUI, generated documentation, or APIs to connect with data governance tools.

DataOps and Migration

The rise of DataOps emphasizes the need for easy deployment of changes using tools like Git. Modern ELT tools support agile working by building deployment pipelines and regression testing capabilities, allowing regular changes to accommodate source system updates or new data sources while ensuring data integrity.

Migrating to a modern analytical platform can be achieved by transitioning from a legacy analytics platform. Leading Edge IT can assist with this process.

data integration

Conclusion

Cloud-based platforms such as Snowflake offer immense scalability for compute tasks, making them ideal for modern data platforms. Incorporating ELT tools like Matillion further optimizes these setups by streamlining workflows and reducing the total cost of ownership (TCO). By integrating replication solutions such as HVR, you can automate data synchronization across environments. When paired with ELT and cloud-based data warehouses, these tools enable efficient, reusable templates with shared components, eliminating manual coding and fostering agility in data management. This combined approach drives efficiency, scalability, and flexibility in your data architecture.

Development

The development is done in Python using pandas, seaborn and, of course sk-learn libraries.  Since the product will bear a graceful name, we will be putting our best effort create modular architecture, lightweight code-style and test coverage.

Fine-tuning parameters will also be made easily using settings file.

{
"dataset_path" : "trained_all.csv",
"dataset_separator" : ";",
"columns_to_remove": ["Unnamed: 0", "Autoclass", "Color 1", "Color 2", "Image", "Images", "Description", "Overview" ],
"columns_to_encode":["Category"],
"columns_to_do_tfidf":["Product name"],
"should_purify" : true,
"problem" : "clustering",
"clustering_settings": {
  "algorithm" : "kmeans",
  "number_of_cluster" : 30,
  "target_column" : "Cluster"

},

"rows_to_debug": 5
}

The following design patterns will be used:

  • Pipeline / Chain of responsibility – in order to build pipeline of execution.
  • Abstract factory – to dynamically generate objects responsible for the picked algorithms
  • Decorator – to provide additional functionality to existing classes
  • MVC – to serve as architectural pattern for web applications later on

Roadmap

At this point data preprocessing is implemented: label encoding, tf-idf textual fields transformations, excessive columns removal.

The steps to follow are:

  • To implement clustering algorithms
  • To implement classification algorithms
  • To implement regression algorithms
  • To add visualization
  • To add support of different datasources (.txt, SQL etc)
  • To wrap inside web application
