The purpose of this category is to organize database management systems by the kind of Inter-Process Communication they use and the manner in which connections to the database are made -- such as with a client/server model (most common) or a serverless API.
PostgreSQL (/ ˌ p oʊ s t ɡ r ɛ s k j u ˈ ɛ l / POHST-gres-kew-EL) [11] [12] also known as Postgres, is a free and open-source relational database management system (RDBMS) emphasizing extensibility and SQL compliance.
A container represents an application or a data store; Component diagrams (level 3): decompose containers into interrelated components, and relate the components to other containers or other systems; Code diagrams (level 4): provide additional details about the design of the architectural elements that can be mapped to code.
An architectural model (in software) contains several diagrams representing static properties or dynamic (behavioral) properties of the software under design [1] [2] [3]. The diagrams represent different viewpoints of the system and the appropriate scope of analysis. The diagrams are created by using available standards in which the primary aim ...
A process-data diagram (PDD), also known as process-deliverable diagram is a diagram that describes processes and data that act as output of these processes. On the left side the meta-process model can be viewed and on the right side the meta-data model can be viewed. [1] A process-data diagram can be seen as combination of a business process ...
A data-flow diagram is a way of representing a flow of data through a process or a system (usually an information system). The DFD also provides information about the outputs and inputs of each entity and the process itself. A data-flow diagram has no control flow — there are no decision rules and no loops.
Physical data model options. [1] A physical data model (or database design) is a representation of a data design as implemented, or intended to be implemented, in a database management system. In the lifecycle of a project it typically derives from a logical data model, though it may be reverse-engineered from a given database implementation.
Database design is the organization of data according to a database model. The designer determines what data must be stored and how the data elements interrelate. With this information, they can begin to fit the data to the database model. [1] A database management system manages the data accordingly.
