OTBI is short for Oracle Transactional Business Intelligence. It is used to generate real-time reports, dashboards, and analysis using subject areas.OTBI is simpler for business users as it requires no complicated SQL. Users can choose columns, add filters, design charts, and generate dashboards using existing subject areas.
7. What is the difference between BI Publisher and OTBI?
BI Publisher is suited to generate complicated and structured reports which may involve SQL. On the other hand, OTBI is used for creating real-time dashboards.BI Publisher is more suited for payslips, invoice, purchase order, and integration file reports. OTBI is more suited for dashboards, charts, and operational reports.
8. What is HCM Data Loader?
Oracle Fusion HCM Data Loader, or HDL, is the application that allows importing, updating, and deleting of HCM data from Oracle Fusion database. This application is used for the management of the following data types: employee data, job data, position data, salary data, assignment data, and element entry data. HDL uses a .dat file, which is stored in the zipped folder and loaded into Oracle Fusion.
9. What is the structure of an HDL file?
The HDL file will contain the meta-data lines and data lines. The meta-data line provides the business object and its attributes. The data line will provide the actual value for the load.Usually, HDL is in the format of parent-child. For example, the worker data could include personal data, working relationship, task assigned, and salary information.
10. What is HCM Extract?
HCM Extract is a tool used to extract data about employees from Oracle Fusion HCM. It can be used for reporting, payroll, attendance system, benefits provider, compliance, and other third party applications. HCM Extract is used to extract data from Oracle Fusion HCM, whereas HDL is used to load data into Oracle Fusion HCM.
11. What is FBDI in Oracle Fusion?
File-Based Data Import is abbreviated as FBDI and is employed in importing bulk data into Oracle Fusion application using a specified spreadsheet template. It is popularly utilized in Finance, Procurement, SCM, Projects and other modules. The FBDI process involves download of templates, entry of data, creation of CSV file, upload of zip file, and import jobs.
12. What is the difference between HDL and FBDI?
The usage of HDL is limited to Oracle Fusion HCM data loading. FBDI is used for loading data related to Financials, Procurement, SCM, Projects, etc.
HDL uses .dat files whereas FBDI makes use of template spreadsheets and CSV files. When it comes to loading employees, assignments, and pay rates, HDL will be used. When it comes to loading invoices, suppliers, journals, or items, FBDI will be used.
13. What are REST APIs in Oracle Fusion?
REST APIs are essential when it comes to integrating Oracle Fusion with other external applications. REST APIs enable the application to access and manage the database by use of GET, POST, PATCH, and DELETE commands.
REST APIs are very essential when it comes to integration, automation, mobile applications, portals, and even third-party applications. The Oracle Fusion Cloud technical training requires the students to perform REST API tests using Postman.
14. What is the difference between REST and SOAP web services?
REST is a lighter approach that works with JSON, whereas SOAP is a more rigid approach that works with XML. REST makes use of HTTP methods, whereas SOAP adheres to service agreements.
REST is a much-preferred choice when it comes to modern projects owing to its simplicity. However, SOAP is often used for Oracle Fusion integrations.
15. What is Oracle Integration Cloud?
OIC (Oracle Integration Cloud) is a cloud solution which helps you integrate with other applications along with the integration of Oracle Fusion applications. In OIC you have support for adapters, mapping, scheduling, orchestration, monitoring, and error handling.
