Waltz 1.3

Release: 20 April 2017

Features

The majority of changes in this release are centered around
three main new features:

Surveys

Surveys allow for the collection of ad-hoc data within
the overall structure of Waltz. Surveys are focused on a
specific entity type (e.g. APPLICATION, CHANGE_INITIATIVE)
and issued to users matching a given set of roles describing
their involvement with the entity. The set of target entities
for the survey is derived from a Waltz selection mechanism
(e.g. apps under a specific organisational unit, apps performing
a specific function etc.).

Flow Diagrams

Flow Diagrams allow users to visually illustrate how data flows
between applications (and actors). Unlike the existing logical
flow view these diagrams can show the full upstream and downstream
flows.

Physical Specification Definitions

In 1.2 flows of information between applications was captured at the
logical and physical levels. However the physical aspect only captured
high level information such as the file name and frequency. In 1.3 we
allow detailed descriptions of the files contents to be defined. This may
be versioned and associated to instances of the physical flow.

Other

Major schema changes

Changes to existing tables are listed below:

Physical flows are now directly owned by logical flows.
- added: logical_flow_id
- dropped: target_entity_id/kind
The flow_decorator table became logical_flow_decorator
- added last_updated_by/at
Logical flows have a soft delete flag field (is_removed)
