app_user Application User false A user authorized to use the FootPrints system. The user is either a Customer User or an Agent User. The application user holds the minimum information needed to identify the user and associate the user with a user profile, where user settings are stored. A contact is not necessarily an application user. An application user entry is required in order for the user to access any online functions.

pwd Password This space intentionally left blank. varchar(255)

email_addr Email Address An email address for the Application User. nvarchar(4000)
delete_date Delete Date The value of a Application User, stored as a date. datetime
cntnr_defn Container Definition true true The definition of a Container and the associated Configuration_Settings at the container level. This would include the collection of Item Definitions. The Container_Definition will have a Container Class identifier (Workspace, CMDB, Address Book) and may have specializations such as Workspace_Container_Definition. As much as possible, the Container Definition will suffice to describe any Container Type. There will be an association to a default Container Template, as well as more application specific Container Templates that can be chosen to initially populate the Container Template. There will also be Container Group Definition, and Container Group Templates. See the database views v_cntnr_defn, v_cntnr_defn_active.

db_schema_name Database Schema Name The name of the database schema. It is a database object name, limited to 30 characters in length. varchar(30)
defn_id Definition Id A Foreign Key to the Definition table. bigint
defn_lock Definition Lock true true A pessimitic lock of a definition. The lock helps implement single session editing. It is intended to be used for container definitions, but may be used by other definitions as well. This is not a table it is implemented with configuration settings.
Physical Name Attribute/Column Name Definition Physical Data Type
locked_by Locked By a string description suitable for display of a session user or component that owns a lock. varchar(255)
create_date Create Date The date that the Definition Lock was created. datetime
defn_id Definition Id A Foreign Key to the Definition table. bigint
token Token A Global Unique IDentifier search key for the System Session, composed of letters and numbers. The session table is not persisted to the database for performance and integrity reasons. Locks will be cleared by the application in normal use, and may be cleared if they are orphaned. varchar(255)
item Item true true The Item is the abstract class for Issue, Configuration Item, Address Book entry, and other information items that are the main information entities in FootPrints. The Item structure and behavior is defined by its Definition. The Item is namespaced, identified by, and logically stored in the single parent container. It can be referenced in the same manner both inside and outside the container. The Item is the storage model and the implementation for the Item Definition. There are many important specializations of the Item class, and there even more Template definitions of Container/Item that provide an end-user application experience to the End-User. The Item implementation must implement flexible schema in an easy to manage, well engineered, and high performing way. The item can store user-defined and user-named fields defined in its definition. The Item could implement the nice-to-have features such as an inheritance model for Item subtypes, and have the ability to represent collections of subordinate items. The Item data can be imported, exported, or synchronized with external data sources. The Item data can be linked and synchronized with other items in the same Instance.
