Data Flow Diagram Model

Data Flow Diagram (DFD) is a technique of graphical structural analysis, describing the sources external to the system, recipients of data, also logical functions, data flows and data stores that are accessed. The DFD's goal is to show how each process converts its inputs into the outputs and to identify relationships between these processes, at this make the system's description clear and understandable at every level of detail. Historically happened that for describing Data Flow Diagrams are used two notations - Yourdon and Gane-Sarson that differ each from other by graphical representation of symbols. The DFD model, like most other structural models is a hierarchical model. Each process can be subjected to decomposition on the structural components, the relationships between which in the same notation can be shown on a separate diagram. Typically, several DFD models are built when modeling the system. ConceptDraw DIAGRAM software enhanced with Data Flow Diagrams solution ideally suits for creation DFD models and professional drawing Data Flow Diagrams.

Fire Exit Plan. Building Plan Examples

Fire exit plan or Emergency exit plan is an obligatory scheme for schools, universities, hospitals, hotels, business centers, metro, airports, and a lot of other buildings, public and private institutions. Fire exit plan depicts detailed plan of the building with marked emergency exits on it and helps to implement faster evacuation in various emergencies such as a fire. If a regular exit is blocked by fire, the plan helps to find the alternative exits, on the route to which are placed the signs leading to it. Fire and Emergency Plans solution from the Building Plans area of ConceptDraw Solution Park provides examples and samples, Fire and Emergency Plan quick-start template and vector stencils library with fire-fighting equipment design elements for drawing different types of emergency and fire schemes and plans: Evacuation plans, Fire Exit plans, Home Emergency plans, School Emergency plans, Office Emergency plans, Fire Emergency plans, Fire Evacuation plans, Fire Safety diagrams, Business Emergency plans, etc.

Emergency Plan

The Fire Emergency Plan illustrates the scheme of the building and location of the main and fire exits for a safe evacuation, and clearly defines directions to them on the plan. Fire Emergency Plans are constructed on the case of unexpected or emergency situations, fires, hazardous leaks, natural disasters, and other sudden events. They must to be obligatorily on the plain sight at every building and on each floor, at living houses and apartments, schools and universities, medical centers, clinics and hospitals, office buildings, banks, cafes, restaurants, and also at all other public buildings and institutions. The Evacuation plans and Emergency Plans preliminary designed in ConceptDraw DIAGRAM software help employees and family members when some emergency events happen and let avoid the accidents and sad consequences, prevent injuries and fatalities, allow reduce damages and speed the work resumption. Start drawing emergency blueprint from floor bounds, then add the inner walls and doors, and finally use bright arrows to visually show evacuation directions to fire exits. ConceptDraw is a serious alternative to Visio. It's a desktop based solution aimed at professional designers working in CAD environments. It is also a good option for those who work between Mac and PC because one license is valid for both.
