Choose to implement Vector Utility PL/SQL packages to perform chunking, embedding, and text generation operations along with text processing and similarity search, both within and outside the database. You can schedule these operations as end-to-end pipelines. The supplied PL/SQL packages for vector generation are DBMS_VECTOR and DBMS_VECTOR_CHAIN.

These packages can work with both vector embedding models in ONNX format (by importing these models into the database) and third-party vector embedding models (by calling third-party REST APIs). Each package is made up of subprograms, such as chainable utility functions and vector helper procedures.

• About Chainable Utility Functions and Common Use Cases
  These are intended to be a set of chainable and flexible "stages" through which you pass your input data to transform into a different representation, including vectors.
• About Vector Helper Procedures
  Vector helper procedures let you configure authentication credentials, preferences, and language-specific data for use in chainable utility functions.
• Supplied Vector Utility PL/SQL Packages
  Use either a lightweight DBMS_VECTOR package or a more advanced DBMS_VECTOR_CHAIN package with full capabilities.
• Terms of Using Vector Utility PL/SQL Packages
  You must understand the terms of using REST APIs that are part of Vector Utility PL/SQL packages.
• Validate JSON Input Parameters
  You can optionally validate the structure of your JSON input to the DBMS_VECTOR.UTL and DBMS_VECTOR_CHAIN.UTL functions, which use JSON to define their input parameters.
