Properties
The Pentaho Metadata Editor allows you to define and manage properties that describe your data model. These properties serve as metadata—descriptive information about your data objects—enabling users and applications to interact with data more effectively through consistent formatting, security rules, and custom attributes.
Required Properties
All physical objects (like tables) and many business objects have mandatory properties that are automatically created and cannot be deleted. These exist for a critical reason: they prevent users from accidentally removing properties that are essential for SQL generation to work properly. For example, a physical table must always have a "Target Table" property defined; without it, the SQL generator would fail and produce errors. Think of required properties as safeguards that maintain system integrity.
How Properties work?
A property consists of two parts: an identifier (a key) and a value. Together, these form a collection—essentially a map of attributes assigned to specific business objects like business columns or business tables.
