Nucleus Query Language
NUQL is an executable shell command that facilitates retrieval, validation, processing, update and deletion of records using a SQL-like syntax. NuQL inherits rules encapsulated within a Nucleus rule-set (screen) and enables passing data to / from client - server environments.

NuQL enforces system security according to user and/or group profiles, while providing a robust transaction layer that enforces referential integrity during processing.

NuQL methods / options include:

• INIT - Initializes internal data tables
• SESSION - Assigns a session id
• SELECT - Selects and builds a DynaSet
• READ - Select and builds the DynaSet, setting locks
• BROWSE - Retrieves a page from a previous SELECT/READ
• RELEASE - Releases locks based on criteria.
• REFORMAT - Writes generated DynaSet items
• UPDATE - Updates or adds items through the specified ruleset
• INSERT - Writes a new item or inserts a new row.
• POST - POSTs the contents of the current DynaSet tables.
• DELETE - Deletes an item or set of items
• VALIDATE - Process the validate trigger
• CORRELATIVE - Process the correlative trigger
• CHOOSE - Retrieves a list of possible field values as defined
• SEARCH - Retrieves results of an indexed search

NuQL facilitates passing data to and from a Client Server User Interface. Many additional format options and modifiers are available.
