As a banker, wouldn’t it be beneficial if you could track the history of a data point from its origin to its current state? This is precisely what modern data transformation tools enable, offering comprehensive data lineage features. They allow you to understand how data has been manipulated, offering transparency and accountability.
These trends underscore the profound impact of data transformation tools on consumer banking. They are not just changing how banks handle data, but also the very fabric of decision-making processes in the banking sector. As we delve deeper into this subject, let’s look at a compelling case study of dbt’s application in generating cross-sell leads.
How dbt Transformed Cross-Sell Lead Generation for Banks
In the ever-expanding sea of consumer banking, the key to maintaining a competitive edge lies partially in the ability to effectively generate cross-sell leads. This is where the importance of leveraging your existing customer portfolio comes into play. Specifically, focusing on credit card customers, which is often the largest credit portfolio of all banks, as a starting point can pave the way for identifying potential customers for other lending products such as personal loans or mortgages.
However, the struggle of generating these qualified leads arises from the need to integrate data from various sources. These sources include demographic information, credit performance, and credit policies, all of which exist in different formats. The traditional method that banks employ involves extracting this data from various systems using SQL, transforming it, and then exporting it to Excel files for further aggregation and transformation. This process contains those pitfalls:
– Data Latency: Delays in data processing can seriously impact the timely identification and approach of potential cross-sell leads.
– Labor Intensity: The process of manually extracting, transforming, and aggregating data is extremely time-consuming and resource-intensive.
– Error Prone: Manual data handling increases the risk of errors, which can lead to misguided decision-making and missed opportunities.
The primary function of dbt (data build tool) that makes it invaluable in this context is its ability to construct data models. This is achieved by breaking down a monolithic SQL script into manageable, comprehensible modules. Imagine the convenience of being able to work with modules instead of getting entangled in a single, complex SQL script. Doesn’t that sound like a breath of fresh air?
dbt significantly enhances the clarity and reusability of your SQL scripts. It is a game changer in the world of data transformation. In more concrete terms, dbt offers a plethora of benefits. Shall we delve into these?
– Clarity: By breaking down your SQL scripts into modules, dbt brings much-needed clarity to your data models. Gone are the days when you need to navigate through a single, extensive script. Instead, you can focus on individual pieces, making your work much simpler and less error-prone.
– Reusability: Once your SQL scripts are modularized, they become readily reusable. This means you can leverage a piece of script in multiple scenarios, enhancing your efficiency and productivity.
A key advantage of dbt is its SQL-centric nature. If you are familiar with SQL, you’re already equipped to use dbt. It allows you to write transformations as SQL SELECT statements, making it easier to understand and maintain the transformation logic.
Why is dbt the ideal tool for this use case?
First, dbt follows the principle of code over configuration. This means that instead of relying on a GUI or a series of checkboxes, you write code to define your data transformations. The code you write is in SQL, a language that most data analysts are already proficient with, reducing the learning curve and facilitating easy adoption.
Eliminating Manual Data Transformation
Manual data transformation through platforms like Excel and monolithic SQL scripts are common practices in many banks. However, this method is not without its pitfalls. It may initially seem convenient and straightforward, but as the complexity and volume of data grow, so do the challenges.
– Time-Consuming: The first and most obvious challenge is the time investment. Pulling, cleaning, transforming, and loading data manually is a labor-intensive process that can eat up significant chunks of your workday.
– Error-Prone: When dealing with large volumes of data, the risk of errors increases exponentially. A single mistake in a formula or a missed data point can drastically skew your results.
dbt provides a robust solution to this problem.
