Use Case Category: Finance

Demo Application 1: Assess the Risk of a Loan

Objective - Determine whether a loan will be approved or not by the issuing bank

Overview

From source:

“The bank wants to improve their services. For instance, the bank managers have only vague idea, who is a good client (whom to offer some additional services) and who is a bad client (whom to watch carefully to minimize the bank loses). Fortunately, the bank stores data about their clients, the accounts (transactions within several months), the loans already granted, the credit cards issued The bank managers hope to improve their understanding of customers and seek specific actions to improve services. A mere application of a discovery tool will not be convincing for them.

The data about the clients and their accounts consist of following relations:

• relation account - each record describes static characteristics of an account,

• relation client - each record describes characteristics of a client,

• relation disposition - each record relates together a client with an account i.e. this relation describes the rights of clients to operate accounts,

• relation permanent order - each record describes characteristics of a payment order,

• relation transaction - each record describes one transaction on an account,

• relation loan - each record describes a loan granted for a given account,

• relation credit card - each record describes a credit card issued to an account,

• relation demographic data - each record describes demographic characteristics of a district.

Each account has both static characteristics (e.g. date of creation, address of the branch) given in relation "account" and dynamic characteristics (e.g. payments debited or credited, balances) given in relations "permanent order" and "transaction". Relation "client" describes characteristics of persons who can manipulate with the accounts. One client can have more accounts, more clients can manipulate with single account; clients and accounts are related together in relation "disposition". Relations "loan" and "credit card" describe some services which the bank offers to its clients; more credit cards can be issued to an account, at most one loan can be granted for an account. Relation "demographic data" gives some publicly available information about the districts (e.g. the unemployment rate); additional information about the clients can be deduced from this.”

Classification:

The file structure is going to look like this:

Open

District is the parent of Account and Client; Account is the parent of Loan, Order, Transaction, and Display; Display is the parent of Card

 

Download the files:

district

account

client

loan

order

transaction

Classifying the Application:

Based on the data technology used and the business use, the application is classified as below:

Step 1: Setting up the Application

Now that the business use and classification of the application is established, the application can be created using the UI. In AdminUI, set up the application by going to the Application Configuration tab, select Create New, and filling out the file structure. Make sure to indicate District as the parent of Account and Client, Account as the parent of Loan, Order, Transaction, Display, and Display as the parent of Card.

Open

We will begin first with the District Dataset:

Step 2: Meta Model, Ingest Model, and Workloads

We are going to use the Bulk Upload Meta feature to create our meta model for the District dataset. In the AdminUI menu , under the Meta Model dropdown, select the Bulk Upload Meta option. Select the Loan Application module and District entity, and import the meta model CSV file into the bulk upload. Once you hit submit, this will automatically generate the meta model for the District dataset.

Next, similar to meta model you can bulk upload ingest model in AdminUI. Or create ingest model by selecting options.

Once we submit the Ingest Model, we can run the workloads under the Workload Management/Run Workloads page.

Once you confirm that the SDL-FDL workload ran correctly, run the FDL-BDL workload next.

Data Upload

Upload data using 'Data Upload' option. Select the Loan Application module and District entity, and CSV file into the data upload. Once you hit submit, this will automatically upload the district dataset to SDL/Land folder in datalake.

Visualizations

After adding the datasets, you can select any one of them to bring up the Charts page. Here, you can pick which type of visualization you would like to create and the parameters for that visualization. Below are three examples of charts you can make in SprngyBI that show the correlations between the various districts, regional statistics, loan amounts and durations, and the status of the loans.

Use Case Category: Sports

Demo Application 1: Evaluating NBA players' performances relative to their salaries

Objective - Build the most efficient team while constraining to a team’s cap space

Overview

With the NBA’s increased emphasis on data analytics, team managers have access to numerous metrics that show a player’s offensive and defensive efficiency. One such metric is FiveThirtyEight’s RAPTOR method, which highlights a player’s net efficiency and wins above replacement (WAR). In 2022, the top five players in Total RAPTOR were as following:

While it would be a manager’s dream to have a starting lineup like this, their combined salaries exceeds the cap space of $122M, leaving the team with both a hefty luxury tax bill and no bench players. The goal of this application is to build a full NBA team that gets the most value per dollar spent, according to the RAPTOR metric.

Classification:

Before defining the application in the system, it is useful to identify key entities and classify the application.

Key Entities:

The file structure is going to look like this:

Classifying the Application:

Based on the data technology used and the business use, the application is classified as below:

Now that the business use and classification of the application is established, the application can be created using the UI. In AdminUI, set up the application by going to the Application Configuration page, select Create New, and filling out the file structure. Make sure to indicate Team as the parent of Players, and Players as the parent of Salaries and Stats.

We will begin first with the Teams dataset.

Data Upload

For uploading a csv file of teams dataset go to Data Upload from left side meu. Select Module name as NBASTATISTICS and entity name as teams from the dropdown option. Select the file to be uploaded and click on Submit.

On submit the dataset gets uploaded to datalake for that entity.

Step 2: Meta Model, Ingest Model, and Workloads

We can now set up the Meta Model in AdminUI:

Next, create the ingest model in AdminUI.

Once we submit the Ingest Model, we can run the workloads under the Batch Management/Run Workloads page.

The Ingest Model will be similar to the one we made for the team’s dataset, the only difference being nesting will be required to be turned on.

After creating the Ingest Model, run the SDL-FDL and FDL-BDL workloads

Repeat the same steps for rest of the entities.
