Program Evaluation and Review Technique (abbr. PERT) is a method developed by Ministry of Defense of the USA in 1958 for the project of creation the missile system Polaris. PERT diagram is one of the tools for project management that lets greatly simplify the planning and scheduling of large and complex projects. PERT diagram provides evaluation of project run-time and labor forces, it helps to analyze the time necessary for execution each of project tasks and the whole project, and to calculate the project critical path. PERT chart depicts the set of tasks connected each other in order of their execution and is constructed according to one of definite rules - AOA (activity on arrow) or AON (activity on node). It doesn't give you ready concrete decisions, but helps to find them.
Design easy the PERT diagrams in ConceptDraw PRO software enhanced with Seven Management and Planning Tools solution from Management area of ConceptDraw Solution Park. You have a possibility to build the PERT chart of any type, but AON variant is easier for building and perception.
Entity-relationship model, also called ER-model, is the main tool of domain modeling on the stage of conceptual design. The modeling of domain data structures is based on the use of graphical tools - Entity-Relationship diagrams (ER-diagrams). The core concepts of ER-Diagram are entity, attribute and relationship. ER-diagram lets visually represent the entities, helps effectively document all properties of designed system and to detail the data storages. To represent the elements at ER-model are commonly used Chen’s notation and Crow’s foot notation, each has its pros and cons. The entity on ER-diagram is represented in the form of rectangle, which specifies its name. An attribute is a property of the entity and relationship is an interaction between the entities. The relationship between two entities is called binary, between more than two entities - ternary.
Specific software, such as ConceptDraw PRO with Entity-Relationship Diagram (ERD) solution from ConceptDraw Solution Park is helpful for easy creation Entity-Relationship Diagrams.
Activity on Node Network Diagramming Tool - Activity Network and Project Evaluation and Review Technique, or PERT, charts are a way of documenting and analyzing the tasks in a project.

The semantic modeling method nowadays is successfully applied in database structure design. It is effective method of modeling the data structures, which is based on the meaning of these data. As a tool of semantic modeling, there are used different types of Entity-Relationship Diagrams. Entity Relationship Diagram (ERD) is applied to visually and clearly represent a structure of a business database. The main components of ERDs are: entity, relation and attributes. An entity is a class of similar objects in the model, each entity is depicted in the form of rectangle and has the name expressed by a noun. Relation is shown in the form of non-directional line that connects two entities. There are several notation styles used for ERDs: information engineering style, Chen style, Bachman style, Martin Style.
The Entity Relationship Diagram symbols used for professional ERD drawing are predesigned by professionals and collected in the libraries of the Entity-Relationship Diagram (ERD) solution for ConceptDraw PRO software.
Building Plan is the basis for implementation construction and repair works. Creation of Building Plans is the main purpose of architects and designers. They are required and even obligatory for builders to accurately implement your wishes and ideas during the building, designing or redesigning your home, flat, office, or any other premise.

The ConceptDraw Flowchart component includes a set of samples and templates. This geathered as flowchart maker toolbox which focused on drawing flowcharts of any industry standards.
Audit Process Flowchart, Audit Flowchart - Audit Flowcharts solution for ConceptDraw PRO Solution Park provides the Audit Flowcharts library with wide variety of predesigned audit flowchart symbols, and also the set of templates and samples allowing you design your own audit flowchart or audit process flowchart in one moment. Simply use any of offered samples and change it for your needs, or fill the desired template.
A flowchart is a type of diagram which represents an algorithm, process or workflow, displays the steps as boxes of various kinds and depicts their order by connecting them with arrows. Any business graphic document will be more colorful and understandable if will use professional-looking and visual diagrams and flowcharts. Flowchart design gives versatile presenting and explaining of the process.
ConceptDraw PRO flowchart software enhanced with Flowcharts solution helps effectively make Flowchart Design. Use of predesigned flowchart symbols and bright color palette offers a fresh view and favorably distinguishes the flowcharts designed in ConceptDraw PRO from the black and white flowcharts on a paper. Preferably to use no more than three or four colors and apply identical for the same shape types. The best flowchart design can be achieved by starting with Flowchart template, or any of suitable ready examples or samples offered in ConceptDraw STORE, open one of them and enter the proper text into each Flowchart shape.
Each symbol of the flowchart has a definition that can't be changed. This means that all flowcharts shapes can be grouped in according to their meaning. Users with ConceptDraw PRO flowchart software can style groups of symbols with close definitions by color sets chosen from complementary palette.
Almost all workflows can be depicted as a flowchart. Colored diagrams are more light for perception of the certain information, this is part of flowchart design. Bright colors need to be used in the key points of Decision symbols, to focus attention on their importance for whole process flow.
Business Process Modeling with ConceptDraw "Business Process Diagrams" Solution
Data Flow Diagrams (DFDs) are successfully used when studying the business processes or systems that involve the transfer of data. They are a visual way to represent the data processing, to model and visualize the flow of data through a computer system and functional requirements for a designed system. They are the good business modeling tool to describe the business events and interactions, the physical systems involving the storage and transfer of data.
ConceptDraw PRO supplied with Data Flow Diagrams solution from Software Development area of ConceptDraw Solution Park is a modern and powerful data flow diagram software. This solution offers large set of predesigned DFD vector objects, grouped to three libraries: Data Flow Diagrams, Gane-Sarson Notation, and Yourdon and Coad Notation. All they and also collection of DFD samples and built-in templates make a good base for ConceptDraw PRO users, providing them all conditions for easy creation the Data Flow Diagrams and Data Flow Models of any complexity.
