What do you meant by static and dynamic modeling?
Static modeling is used to specify structure of the objects that exist in the problem domain. These are expressed using class, object and USECASE diagrams. But Dynamic modeling refers representing the object interactions during runtime. It is represented by sequence, activity, collaboration and statechart diagrams
What are pictorial figures that represent programs?
There are many such systems of diagrams used to aid program design (e.g. data flow diagrams, entity relationship diagrams, control flow diagrams, flowcharts).
What are the advantages of design?
There are various advantages of doing a design before setting out to make something. If you do a good design you will be sure it works.

Design notation modeling languages?
Design notation modeling languages are graphical languages used to represent. Communicate design concepts, structures, and relationships. These languages provide a standardized way to visually express design ideas. Facilitate effective communication among designers, stakeholders, and developers. Some popular design notation modeling languages include: 1. UML (Unified Modeling Language): Widely used in software engineering. UML provides a set of standardized diagrams to represent various aspects of a system. Such as class diagrams, use case diagrams, sequence diagrams, and more. 2. BPMN (Business Process Model and Notation): Used for modeling business processes. BPMN allows the visual representation of activities, events, gateways, and flows. To describe the flow of work within an organization. 3. ERD (Entity-Relationship Diagram): Commonly used in database design. ERD represents the relationships between entities and attributes in a database system. Helping to define the structure and organization of data. 4. SysML (Systems Modeling Language): A language based on UML, SysML extends its capabilities to capture. model complex systems, including hardware, software, and their interactions. 5. ArchiMate: Primarily used for enterprise architecture modeling. ArchiMate provides a comprehensive framework for describing. And visualizing the components, relationships, and dependencies of an organization's architecture. These modeling languages serve as powerful tools to document. Analyze, and communicate designs across various domains and industries.

Does modeling and carving mean the same thing?
no modeling is when u design carving is when u carve it u mold it
Differentiate logical and physical database?
After all business requirements have been gathered for a proposed database, they must be modeled. Models are created to visually represent the proposed database so that business requirements can easily be associated with database objects to ensure that all requirements have been completely and accurately gathered. Different types of diagrams are typically produced to illustrate the business processes, rules, entities, and organizational units that have been identified. These diagrams often include entity relationship diagrams, process flow diagrams, and server model diagrams. An entity relationship diagram (ERD) represents the entities, or groups of information, and their relationships maintained for a business. Process flow diagrams represent business processes and the flow of data between different processes and entities that have been defined. Server model diagrams represent a detailed picture of the database as being transformed from the business model into a relational database with tables, columns, and constraints. Basically, data modeling serves as a link between business needs and system requirements. Two types of data modeling are as follows: * Logical modeling * Physical modeling If you are going to be working with databases, then it is important to understand the difference between logical and physical modeling, and how they relate to one another. Logical and physical modeling are described in more detail in the following subsections. Logical modeling deals with gathering business requirements and converting those requirements into a model. The logical model revolves around the needs of the business, not the database, although the needs of the business are used to establish the needs of the database. Logical modeling involves gathering information about business processes, business entities (categories of data), and organizational units. After this information is gathered, diagrams and reports are produced including entity relationship diagrams, business process diagrams, and eventually process flow diagrams. The diagrams produced should show the processes and data that exists, as well as the relationships between business processes and data. Logical modeling should accurately render a visual representation of the activities and data relevant to a particular business. The diagrams and documentation generated during logical modeling is used to determine whether the requirements of the business have been completely gathered. Management, developers, and end users alike review these diagrams and documentation to determine if more work is required before physical modeling commences. Typical deliverables of logical modeling include * Entity relationship diagrams An Entity Relationship Diagram is also referred to as an analysis ERD. The point of the initial ERD is to provide the development team with a picture of the different categories of data for the business, as well as how these categories of data are related to one another. * Business process diagrams The process model illustrates all the parent and child processes that are performed by individuals within a company. The process model gives the development team an idea of how data moves within the organization. Because process models illustrate the activities of individuals in the company, the process model can be used to determine how a database application interface is design. * User feedback documentation Physical modeling involves the actual design of a database according to the requirements that were established during logical modeling. Logical modeling mainly involves gathering the requirements of the business, with the latter part of logical modeling directed toward the goals and requirements of the database. Physical modeling deals with the conversion of the logical, or business model, into a relational database model. When physical modeling occurs, objects are being defined at the schema level. A schema is a group of related objects in a database. A database design effort is normally associated with one schema. During physical modeling, objects such as tables and columns are created based on entities and attributes that were defined during logical modeling. Constraints are also defined, including primary keys, foreign keys, other unique keys, and check constraints. Views can be created from database tables to summarize data or to simply provide the user with another perspective of certain data. Other objects such as indexes and snapshots can also be defined during physical modeling. Physical modeling is when all the pieces come together to complete the process of defining a database for a business. Physical modeling is database software specific, meaning that the objects defined during physical modeling can vary depending on the relational database software being used. For example, most relational database systems have variations with the way data types are represented and the way data is stored, although basic data types are conceptually the same among different implementations. Additionally, some database systems have objects that are not available in other database systems. Typical deliverables of physical modeling include the following: * Server model diagrams The server model diagram shows tables, columns, and relationships within a database. * User feedback documentation Database design documentation Understanding the difference between logical and physical modeling will help you build better organized and more effective database systems.
