UML Package Diagram. Design Elements
UML Package Diagram is a type of Structure Diagrams that represents the packages of the model and dependencies between them.
Package Diagrams are used to illustrate the layered architecture of a software system. The packages depict the different layers of a software system. To indicate the types of dependencies between the packages are used the stereotypes.
There are two special types of dependencies between the packages in UML: package import and package merge.
To design UML Package Diagrams use the following shape types:
- Package – it is the mechanism indispensable for organizing the elements and diagrams into the groups.
- Class - it is a description of logical structure of the system, its objects and their behavior in the system.
- Interface - it is a specification of the behavior.
- Object - it is an instance of class, and others.
UML Package Diagrams are very useful for working with large systems, because they allow to clearly view all the dependencies between the elements of these systems.
The Rapid UML Solution for ConceptDraw DIAGRAM contains 13 vector stencils libraries with 393 interactive shapes that you can use to design your UML diagrams.
To design a Package Diagram use the UML Package Diagram library.
UML Package Diagram library contains 23 shapes:
- Class 2
- Class 1
- Line connector
- Smart connector
- Content connector

ConceptDraw Rapid UML solution provides UML Package Diagram library of vector stencils for drawing the package diagrams using package blocks and assembly connectors.
All libraries for creating UML diagrams are available inside the ConceptDraw DIAGRAM Templates and samples are located in the Rapid UML section of ConceptDraw STORE.

Use design element from the UML Component Diagram library to draw your own UML package diagrams of complex systems and software applications.
TEN RELATED HOW TO's:
Developing a software project supposes architecture first. To make it proper, you can use data flow diagram model in your current project.
The data flow diagram represents the Model of small traditional production enterprise that is made using Yourdon and Coad notation. It shows how the data is transfered through a process. According to the notation of Yourdon and Coad a process is represented by circles and data stores are drawn using parallel lines. This DFD was created using the ConceptDraw Data Flow Diagrams solution. Using this solution one can visualize data flow accordingly to the rules of two basic notations used for data flow modeling.

Network Topology in communication networks, a topology is a usually schematic description of the arrangement of a network, including its nodes and connecting lines. There are two ways of defining network geometry: the physical topology and the logical topology.
Network Topology Mapper offers extensive drawing tools professional-looking network diagrams quickly and easily allowing you to clearly represent and communicate network architecture, topology, and design to engineers, stakeholders and end-users.

An abstract representation is usually the first thing you will need while developing a database. To understand the ways that databases are structured, you should look through entity-relationship diagram examples and see the notations features and attributes. With an entity-relationship model you can describe a database of any complexity.
This Entity-relationship diagram is a tool for software developers. It enables every element of database to be managed, communicated and tested before release. This ERD was created using symbols advocated by Chen's notation. Because of a linguistic origin of the Chen’s notation, the boxes representing entities could be interpreted as nouns, and the relationships between them are in verb form, shown on a diagram as a diamond.

The Process Flowchart or Process Flowchart Diagram (PFD) is a visual representation relations between major parts of the system, the steps in a process, and even connections between various systems. The possibility to easy create professional-looking and attractive Process Flowcharts, Business Process Diagrams and Maps which visualize the steps of complex processes is provided by Business Process Diagram Solution from the Business Processes Area of ConceptDraw Solution Park and 16 libraries with 230 process flowchart symbols from BPMN 1.2 and BPMN 2.0.

When we start to speak about databases, we must always mention database structure visualization. One of the most common ways to do it is to create an entity relationship diagram, and to put appropriate symbols on it. It is important either for database projecting and for its' future maintenance.
Entity Relationship Diagram describes data elements and their relationships within a database. There are a set of special symbols that depict each element of an entity relationship diagram. Entities - represents some stable components such as supplier, employee, invoice, client, etc. Relation symbols show how the entities interact. Attributes define characteristics of the relationships. Attributes can be one-to-one or many-to-many. Physical symbols is used in the physical models. They represent items such as fields, tables, types and keys. ERD physical symbols are the building material for the database. Notation lines are used to illustrate the relationships. The most common method is Crow’s Feet notation. You can use ConceptDraw Entity-Relationship Diagram (ERD) solution to represent a database using the Entity-Relationship model.
