One-line Drawing
One-line diagram is a simplified drawing used to represent the electrical system, its main components, sources of power, electrical drives, electrical equipment loads, redundant equipment, and spares. One-line diagram is essential for the proper design of equipment in order to ensure safety, reliability, and high performance of the electrical system, and safety of facilities and their personnel as result.
One-line diagrams have a lot of benefits. They are used to document signal flows and chains of various complexity, and the distribution of incoming power to various equipment. One-line diagrams are indispensable for future testing, coordination of service, and maintenance of the electrical system. They simplify troubleshooting, identification of fault levels and locations to ensure correct power flow downstream till the last step in the chain.
One-line diagram is essential for electrical system analysis and as a plan when updating or responding to an emergency. It shows an electrical distribution system layout in a facility and is the base for a critical response plan. One-line diagram is also a valuable tool to clear the power system and layout of electrical distribution in a facility. It shows a power distribution path from the incoming power source to each load.
One-line diagrams are a necessity for the realization of efficient service and maintenance including coordination studies, load flow and safety evaluation, short circuit calculations, and other engineering studies. The visualization of the power distribution system helps to improve and simplify planning and troubleshooting, and document redundant power paths. It increases the efficiency of maintenance activities, tracking of the key electrical characteristics, capacity, load and interconnections of all facility nodes. It simplifies the identification of fault locations, reduces potential outages, and ensures redundancy.
One-line diagram depicts accurately the electrical components and reflects electrical relationships, and how the system will function. Standardized graphic symbols and lines are used to show components of the power systems like generators, transformers, antennas, circuit breakers, switches, fuses, protective devices, conductors, and more. They ensure the ease of One-line drawing design, readability, and ease of its use. A few current-carrying conductors are shown schematically by one line. The sizes and ratings of the components are also shown in the diagram.

When trying to figure out the nature of the problems occurring within a project, there are many ways to develop such understanding. One of the most common ways to document processes for further improvement is to draw a process flowchart, which depicts the activities of the process arranged in sequential order — this is business process management. ConceptDraw DIAGRAM is business process mapping software with impressive range of productivity features for business process management and classic project management. This business process management software is helpful for many purposes from different payment processes, or manufacturing processes to chemical processes. Business process mapping flowcharts helps clarify the actual workflow of different people engaged in the same process. This samples were made with ConceptDraw DIAGRAM — business process mapping software for flowcharting and used as classic visio alternative because its briefly named "visio for mac" and for windows, this sort of software named the business process management tools.
This flowchart diagram shows a process flow of project management. The diagram that is presented here depicts the project life cycle that is basic for the most of project management methods. Breaking a project into phases allows to track it in the proper manner. Through separation on phases, the total workflow of a project is divided into some foreseeable components, thus making it easier to follow the project status. A project life cycle commonly includes: initiation, definition, design, development and implementation phases. Distinguished method to show parallel and interdependent processes, as well as project life cycle relationships. A flowchart diagram is often used as visual guide to project. For instance, it used by marketing project management software for visualizing stages of marketing activities or as project management workflow tools. Created with ConceptDraw DIAGRAM — business process mapping software which is flowcharting visio alternative or shortly its visio for mac, this sort of software platform often named the business process management tools.

A database is a data collection, structured into some conceptual model. Two most common approaches of developing data models are UML diagrams and ER-model diagrams. There are several notations of entity-relationship diagram symbols and their meaning is slightly different. Crow’s Foot notation is quite descriptive and easy to understand, meanwhile, the Chen notation is great for conceptual modeling.
An entity relationship diagrams look very simple to a flowcharts. The main difference is the symbols provided by specific ERD notations. There are several models applied in entity-relationship diagrams: conceptual, logical and physical. Creating an entity relationship diagram requires using a specific notation. There are five main components of common ERD notations: Entities, Actions, Attributes, Cardinality and Connections. The two of notations most widely used for creating ERD are Chen notation and Crow foot notation. By the way, the Crow foot notation originates from the Chen notation - it is an adapted version of the Chen notation.

A flowchart is a powerful tool for examining processes. It helps improving processes a lot, as it becomes much easier to communicate between involved people, to identify potential problems and to optimize workflow. There are flowcharts of different shapes, sizes and types of flowchart vary from quite basic process flowcharts to complex program flowcharts. Nevertheless, all these diagrams use the same set of special symbols like arrows to connect blocks, parallelogram to show data receiving or rectangles for showing process steps.
Basic flowcharts are used to represent a simple process algorithm. A basic flowchart notation consists of rectangles (business processes), arrows (the flow of information, documents, etc.). The same notation is used in items such as the "decision", which allow you to do the branching. To indicate the start of the entire business process and its termination can be used the "Terminator" element. The advantages of Basic Flowchart are simplicity and clarity. With it you can quickly describe the business process steps. Creating of Basic Flowchart does not require any special knowledge, as easily understand by employees with different levels of education and IQ.
