Agile... Agile Model-Driven Development. Agile Methodologies There are many Agile methodologies: Extreme Programming (XP) Scrum Dynamic System Development Method Crystal Method Feature-Driven Development Lean Development Adaptive Software Development Agile methodologies are all based on iterative-incremental processes, but with very short iterations (weeks rather than months). Agile methodologies are also called adaptive and are usually contrasted with predictive methodologies. Agile Model-Driven Development (AMDD) AMDD is the agile version of MDA. AMDD is an agile, model-driven, iterative-incremental process: Notice that there is no maintenance phase in which new features are added to the code. Implementation is actually a macro-phase consisting of a number of micro-phases: Model-driven development means that code and tests are derived from (UML) models. Agile development means that design is deemphasized.
Agile development is often test-driven, which means that tests are implemented before requirements are implemented. Links. Agile. Systems Analysis Course.

The Unified Modeling Language (UML) is a general-purpose modeling language in the field of software engineering, which is designed to provide a standard way to visualize the design of a system.[1] It was created and developed by Grady Booch, Ivar Jacobson and James Rumbaugh at Rational Software during 1994–95 with further development led by them through 1996.[1] In 1997 it was adopted as a standard by the Object Management Group (OMG), and has been managed by this organization ever since.
In 2000 the Unified Modeling Language was also accepted by the International Organization for Standardization (ISO) as an approved ISO standard. Since then it has been periodically revised to cover the latest revision of UML.[2] Overview[edit] A collage of UML diagrams The Unified Modeling Language (UML) offers a way to visualize a system's architectural blueprints in a diagram (see image), including elements such as:[3] History[edit] History of object-oriented methods and notation Before UML 1.x[edit] [edit] Data flow diagram. Data flow diagram example.[1] A data flow diagram (DFD) is a graphical representation of the "flow" of data through an information system, modelling its process aspects.
A DFD is often used as a preliminary step to create an overview of the system without going into great detail, which can later be elaborated.[2] DFDs can also be used for the visualization of data processing (structured design). [citation needed] A DFD shows what kind of information will be input to and output from the system, how the data will advance through the system, and where the data will be stored. It does not show information about process timing or whether processes will operate in sequence or in parallel, unlike a traditional structured flowchart which focuses on control flow, or a UML activity workflow diagram, which presents both control and data flows as a unified model.
