Data structure diagram with ConceptDraw DIAGRAM
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.
Data structure diagram is a subspecies of the “entity-relationship” diagram type (ERD).
Entities in data structure diagrams are presented in the form of rectangles or rounded rectangles, and connections between them in the form of arrows. The description of an entity is usually placed inside the rectangle, which denotes the entity. The text description of the entity requirements connecting entities is placed near the line which denotes the connection between entities. The description of connection types between entities (one-to-one, one-to-many, etc.) can be different in different notations and differs with the arrow type on the line of connection between entities. The most famous are notations of DeMarco, Jackson and Yourdon.
DSD also used for hierarchical presentation of the complicated entity. Such data structure diagram is usually created in the result of entity decomposition to the set level of detailed elaboration and presented as a tree.
The difference of the data structure diagram from the “entity- relationship” diagram is that DSD more completely defines connections and relations between elements of entities whereas ERD defines connections between entities.

Specification and Description Language (SDL) is used for creating the object-oriented diagrams, visualizing the processes of the state machines for the systems of communication, telecommunication, automotive, aviation and medical industries. SDL is a specification language for creating specifications, descriptions of the behavior, data, and inheritance for real-time systems.
This sample shows the SDL Diagram of the process game.

There are several basic topologies including bus, star, point-to-point, ring and a hybrid. Two computers can form a fully connected network topology, and as the number of network nodes increases, the network diagram gets more complicated. This type of topology is also called a full mesh.
This is a visual example of a computer network built using a mesh topology. This diagram presents the schematic structure of the full mesh network topology. A common mesh network topology means that each network device is connected with several points in the network, so if the one node of the network goes down, it does not cause an issue with an operability of the entire computer network. In a full mesh network topology, every computer or device in the network is interconnected with each of the other devices in the network.

The Organizational Chart is a diagram that shows the structure of the organization and the relationships of its parts. There are many ways to present the Organizational Chart. One of them is the Horizontal Organizational Chart: the parts of the diagram are arranged from left to right, or from right to left.
This sample was created in ConceptDraw DIAGRAM diagramming and vector drawing software using the Organizational Charts Solution from the Management area of ConceptDraw Solution Park.

A Home Area Networks (HAN) is a type of local area network that is used in an individual home. The home computers can be connected together by twisted pair or by a wireless network. HAN facilitates the communication and interoperability among digital devices at the home, allows to easier access to the entertainments and increase the productivity, organize the home security.
This example was created in ConceptDraw DIAGRAM using the Computer and Networks Area of ConceptDraw Solution Park and shows the home network diagram.

It is very difficult to get into database model idea without any examples. To create one, you can use Chen’s notation for Entity Relationship Diagrams (ERD) and try to see all the peculiarities yourself. This notation describes entities and relations as basic geometric shapes like rectangles and diamonds.
Chen notation for Entity-relationship diagrams is used for designing relational databases. It depicts the database entities as a set of subjects. For example events, people, ideas, etc. All entities has common characteristics (attributes). Any object of the system is identified as the sole and unique. The name of entity should indicate the class or type of the the whole object, not a given example. The connection commonly represents a relationship between entities. Conceptdraw Entity-Relationship Diagrams (ERD) solution provides the libraries with ready-to-use ERD element fitting Chen's notation objects and relationships.
