     - OCI Language and Document Understanding are cloud-based AI services for performing sophisticated text analysis and extracting data from all kinds of documents e.g. Passport, Driving License, Invoices, Receipts, etc. You can use these services to build intelligent applications by leveraging REST APIs. You can use these services to build intelligent applications by leveraging REST APIs and automating using Oracle Integration Cloud. This allows you to process unstructured text for use cases such as sentiment analysis, service ticket classification, document extraction, and more using pre-trained models or your own custom models leveraging OCI Data Labelling.

+    - Message-Level Encryption (MLE) is a security technique used to protect the confidentiality and integrity of a message during transmission. It involves using encryption algorithms to scramble the contents of a message so that only the intended recipient, with the decryption keys, can read it. This reference architecture shows how you can implement message level encryption in OIC using OCI Vault Service.

     - Demo Video (part of Red Hot Webinars) where we show an initiative to enhance and modernize the EBS platform for better reach and ease of users. No change to existing workflow approvals in EBS and standard EBS Self Service Submissions has been required. From a mobile VBCS app employees are able to submit their IQAMA Renewal (Residence renewal) or Overtime Work Requests and their managers (up to 2 management chains up) are able to check the request and perform their approval. It uses EBS Integrated SOA Gateway which exposes custom and standard EBS APIs reached through OIC REST adapter.
