Use Case Modeling takes effort and time, and requires a certain degree of expertise. Why do we do Use Case Modeling then ? What are the benefits of such an approach ?
Use cases are an effective technique for capturing and communicating functional requirements. Use cases provide some very clear benefits to the Analysis Phase.
- One […]

What are Use Cases and what is Use Case Modeling ?
A use case is a technique used in software and systems engineering to capture the functional requirements of a system. Use cases describe the interaction between a primary actor—the initiator of the interaction—and the system itself, represented as a sequence of simple steps. A Use […]
Details of UML diagrams

In order to try and explain these diagrams, I will give their categorization and then an explanation of each diagram:
Structure diagrams emphasize what things must be in the system being modeled. This is a type of diagram that depicts the elements of a specification that are irrespective of time. This includes class, composite structure, […]
Listing of UML Diagrams
Filed Under Architecture, UML, Design, Model, Development, Software | Posted on October 3, 2007
Depending on the literature that you read, you will find a mention of 9 or 13 diagrams used in UML.
If you read the literature for 9 diagrams, then these are the list of diagrams:
Structural Diagrams
* Class Diagram
* Object Diagram
* Component Diagram

Benefits of UML and some goals
Filed Under Architecture, UML, Benefits, Design, Techniques, Development, Process, Software | Posted on September 29, 2007
Why was UML made ? The primary goals in the design of the UML were:
- Provide users with a ready-to-use, expressive visual modeling language so they can develop and exchange meaningful models.
- Provide extensibility and specialization mechanisms to extend the core concepts.
- Be independent of particular programming languages and development processes.
- Provide a formal basis […]
What is UML ?
Filed Under Architecture, UML, Design, Techniques, Process, Terms, Development | Posted on September 29, 2007
UML stands for ‘Unified Modeling Language’. That’s fine, but what exactly does it mean ? This is a programming language that is used for object-oriented software development. To organize program code more efficiently, programmers often create “objects” that are sets of structured data within programs. UML, which has been standardized by the Object Management Group […]
Differences between HLD and LLD
Filed Under Techniques, Design, Model, Process, Development, Software | Posted on September 27, 2007
For people who have been involved in software projects, they will constantly hear the terms, High Level Design (HLD) and Low Level Design (LLD). So what are the differences between these 2 design stages and when are they respectively used ?
High – level Design gives the overall System Design in terms of Functional Architecture and […]
What is software low level design ?
Filed Under Design, Techniques, Model, Development, Software | Posted on September 27, 2007
The low level design document for a project should provide a complete and detailed specification of the design for the software that will be developed in the project, including the classes, member and non-member functions, and associations between classes that are involved. By the end of the Low Level Design stage, the code should be […]
The software architecture design process
Filed Under Document, Architecture, Design, Techniques, Model, Software | Posted on September 24, 2007
Early attempts to capture and explain software architecture of a system were imprecise and disorganized - often characterized by a set of box-and-line diagrams. During the 1990’s there was a concentrated effort to define and codify fundamental aspects of the discipline. Initial sets of design patterns, styles, best practices, description languages, and formal logic were […]
What is software architecture design ?
Filed Under Design, Architecture, Techniques, Model, Development, Process, Software | Posted on September 23, 2007
“Architecture is concerned with the selection of architectural elements, their interaction, and the constraints on those elements and their interactions… Design is concerned with the modularization and detailed interfaces of the design elements, their algorithms and procedures, and the data types needed to support the architecture and to satisfy the requirements.”
Software architecture is commonly defined […]
