# Roundup Glossary

class
  a definition of the properties and behavior of a set of items
classname
  the name of a class. It must start with a letter, end with a letter or “_”, and only have alphanumerics and “_” in the middle.
db
  database used to store the data in the tracker. Roundup supports 4 databases: dbm (Berkeley DB/BDB), SQLite, PostgreSQL, MySQL/MariaDB.
definitional class
  a class that exists to define a discrete set of values. For example status or priority.
designator
  a combined classname + itemid reference to any item in the hyperdb. E.g. `issue26`. Note that form values can include something that looks like a designator composed of a classname, a dash ‘-’, and a number. E.g. `file-1`. These are used to create new instances of a class via the web interface.
hyperdb
  a software layer between the user and the underlying db. It is responsible for mutating the underlying db when the schema changes. It also executes the detectors when items in the db change.
item
  a collection of data that forms one entry in the hyperdb.
itemid
  an integer reference to a particular item of one class. Internally it is stored as a string and not an integer number. This results in a string not numeric sort by id in some circumstances.
property
  one element of data that makes up an item. In Roundup, the set of item properties may be changed as needed - even after the tracker has been initialized and used in production.
schema
  the definition of all the classes and properties that make up a tracker. Contained in the file `schema.py`. The permissions for the schema items are usually defined in the same file.
tracker
  the schema and hyperdb that forms one issue tracker
tracker home
  the physical location on disk of a tracker. It has the `config.ini`, `schema.py` files for the tracker.
