Entity Relation Diagram (ERD)
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
Data Flow Diagram (SSADM)
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
Data Model (IDEF1X)
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
Math symbols
A few math symbols, readily available.
Smart Grid Icons IIa
Some parts Copyright © 2010, 2012, 2013 by John Egan. For G.hn technology drawings, I needed other icons so I worked to create the basic blocks then add the drawings, all in OG. I have included the basic blocks as blanks so that others can create their own icons and add them in later on.
IAN Agriculture Symbollibrary
This is the first batch of IAN symbols. This Stencil contains the Agriculture symbols. The IAN symbol libraries contain over 1500 custom made vector symbols designed specifically for enhancing science communication skills. The symbols allow diagrammatic representations of complex processes to be developed easily with minimal...more
Smart Grid Function Blocks Icons
Aqua optics based icons for components of the electric power grid with the very focus on so called smart grid components.
Round Arrows
A small collection of round arrows to create a circle of arrows. Each arrow can have a different color.
