Difference Between HDL and HSDL in Oracle HCM

 Difference Between HDL and HSDL in Oracle HCM: A Quick Guide

In Oracle HCM Cloud, data loading and migration are essential for managing workforce information efficiently. Two powerful tools provided by Oracle for this purpose are HDL (HCM Data Loader) and HSDL (HCM Spreadsheet Data Loader). While both serve similar goals, they cater to different user needs and scenarios.


What is HDL (HCM Data Loader)?

HDL is a file-based data loading tool that allows bulk upload of business objects into Oracle HCM Cloud. It uses structured data files (usually .zip files containing .dat files) and is ideal for large-scale data migrations or integrations from third-party systems.

Key Features:

  • Supports large volumes of data
  • Suitable for complex data structures
  • Can be automated using scripts and web services
  • Requires technical knowledge of data formats and object models

Use Cases:

  • Initial data migration during implementation
  • Regular integrations from external systems
  • Complex updates across multiple business objects


What is HSDL (HCM Spreadsheet Data Loader)?

HSDL is a spreadsheet-based tool that enables users to load data using Excel templates. It’s designed for business users or HR specialists who may not have technical skills but need to update or load data occasionally.

Key Features:

  • Excel-based user interface
  • Validates data in real-time before upload
  • Easy to use with minimal training
  • Less technical than HDL

Use Cases:

  • Ad hoc or low-volume data updates
  • HR users entering employee data directly
  • Quick corrections or additions without IT involvement


Key Differences Between HDL and HSDL

Feature                        HDL                                                     HSDL

Interface                        File-based (DAT files)                     Excel spreadsheet

User Audience        Technical users (IT, Developers)     Functional users (HR, Admins)

Data Volume                High volume / bulk data loads             Low to medium volume

Complexity                Supports complex business objects     Best for simpler, flat data structures

Real-Time Validation No (errors found during upload)     Yes (validates in Excel)

Automation                 Easily scriptable for integrations      Manual use via UI


Conclusion

Both HDL and HSDL are essential tools in Oracle HCM Cloud, but they serve different purposes. HDL is best for large, complex, or automated data loads, while HSDL is ideal for user-friendly, ad hoc updates. Understanding their differences ensures you choose the right tool for your business need, improving efficiency and accuracy in your HR processes.

How Tosca Handles TestData Parameterization

Tosca by Tricentis is a powerful test automation tool that provides robust support for test data parameterization, enabling reusable and maintainable test cases. Parameterization in Tosca allows testers to replace hardcoded values with dynamic data, making it easier to run the same test with multiple data sets. Here’s how Tosca handles test data parameterization: Using TestCase-Level Parameters You can define TestCase parameters to pass values dynamically into a test case. Steps: Right-click the TestCase and choose "Create TestCase Parameter". Assign a name (e.g., Username) and a default value. In your TestStep, reference the parameter using the syntax ={ParameterName}. Example: ={Username} You can override these parameters when calling the TestCase in another TestCase or in the TestCase folder. Using TestSheet/TestDataService (TDS) Tosca allows parameterization via TestSheets, a part of the Tosca TestCase Design module. This is the most scalable and maintainable way to manag...

Understanding Tosca TestCases and Modules

 Tosca by Tricentis is a powerful model-based test automation tool widely used for functional and regression testing. One of its biggest strengths lies in its no-code approach to test creation, enabling testers to build robust automated tests without needing deep programming skills. At the heart of Tosca’s architecture are Modules and TestCases, two essential components that help in designing, executing, and maintaining automated tests efficiently. In this blog, we’ll explore what Tosca Modules and TestCases are, how they work, and how they contribute to effective test automation. What Are Tosca Modules? Modules in Tosca represent the building blocks of your test automation framework. They are reusable components that store the technical information about the UI elements (like buttons, fields, checkboxes) or APIs under test. Modules are created by scanning the application and capturing its elements. There are two types of modules: Standard Modules: These are created by scanning the...
