Allows you to draw simple Entity Relation Diagrams (the first page). ERDs are useful in the early stages of a project, especially if you are using formal approach such as Structured Systems Analysis and Design Methodology (for which there is a SSADM stencil) or IDEF0. I have added an extension, which allows indices to be...more
The classic Structured Systems Analysis and Design Methodology by Chris Gane and Trish Sarson. SSADM is better known as Data Flow Diagrams. It is a simple and highly effective systems analysis and design (decomposition) methodology. It uses just four symbols, and it is excellent for communicating with non-technical users. A...more
Allows you to draw IDEF1X-compliant Data Models (examine all five pages). IDEF1X is a methodology and standard (NIST/FIPS 184 in 1993) for modelling Relational databases. It emphasises and promotes data independence; proper use of keys; extensibility; quality; and ease of use, and produces a genuinely Relational database....more
A simple stencil for drawing AMQP and RabbitMQ topologies.
This is a ready-made Fishbone, or Ishikawa, diagram to get you started on your Cause and Effect analysis. The whole diagram is made as a group for easy drag-and-drop between the stencil and your canvas. Before starting to work on your Fishbone diagram, you should ungroup the compound shape. The primary and secondary causes...more
