In the early stages of a development project, use case diagrams are used to describe real-world activities and motivations. A use case diagram (use case: In a use case diagram, a representation of a set of events that occurs when an actor uses a system to complete a process. Normally, a use case is a relatively large process, not an individual step or transaction.) is a dynamic or behavior diagram in UML.
Use case diagrams are valuable for visualizing the functional requirements of a system that will translate into design choices and development priorities. You can refine the diagrams in later stages to reflect user interface and design details.
They also help identify any internal or external factors that may influence the system and should be taken into consideration.This sample was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the UML Use Case Diagram library of the Rapid UML Solution from the Software Development area of ConceptDraw Solution Park.

Nodes of any computer network are somehow organized in a hierarchy or a layout. Some of the common layouts like star network topology are more reliable and some like ring topology withstand high loads better. It is also important to distinguish logical topologies from physical.
This diagram represents a typical view of the star network topology. The star network topology is one of the most frequently used network topologies in the majority of office and home networks. It is very popular because of its low cost and the easy maintenance. The plus of the star network topology is that if one computer on the local network is downed, this means that only the failed computer can not send or receive data. The other part of the network works normally. The minus of using star network topology is that all computers are connected to a single point-switch, or hub. Thus, if this equipment goes down, the whole local network comes down.

Data structure diagram (DSD) is intended for description of conceptual models of data (concepts and connections between them) in the graphic format for more obviousness. Data structure diagram includes entities description, connections between them and obligatory conditions and requirements which connect them. Create Data structure diagram with ConceptDraw DIAGRAM.

In order to be successful, you have to promote your business on the market. One of the ways for planning this promotion is to create a social media DFD Flowchart which will contain all the details of your business strategy. Social media is a very influential tool, and it's a mistake to ignore it.
The following flowchart represents a best way to estimate social media posts, and gives a strategy of responses. This flowchart is designed in the format of cross-functional flowchart. With this format, we can divide the process into three distinct phases. This approach helps to generate well-considered and balanced response on social networks activities. Using ConceptDraw solution for Social Media Response, your reaction to social media posts will positively mirror the values and mission of your business.

The use case diagram (behavior scenarios, precedents) is the initial conceptual representation of the system during its design and development. This diagram consists of actors, use cases and relationships between them. When constructing a diagram, common notation elements can also be used: notes and extension mechanisms.

Database structures are usually described by ER-diagrams which represents entities as boxes with lines-connections between them. You can create any entity-relationship diagram (ERD) by means of ConceptDraw DIAGRAM using ready-to-use templates and special libraries containing all the needed symbols and shapes. Creating a model for your database from now on can take just a few minutes.
ERD (entity relationship diagram) designed to show the logical structure of databases. It intended to depict the relationships between data components (entities). ERDs are a popular tool for software engineers and architects. Using ERD they can manage the every aspect of database design. Also ERD can be used as guidelines for testing and communications before software release. This diagram represents the file reference system of the WordPress web platform. Because entity relationship diagrams have such a broad application area through the prevalence of database technology, it can be applied for a wide range of users.
