What does conceptual design mean?

What does conceptual design mean?

Conceptual design is an early phase of the design process, in which the broad outlines of function and form of something are articulated. It includes the design of interactions, experiences, processes, and strategies. ... Common artifacts of conceptual design are concept sketches and models.

What is a conceptual view?

The conceptual view is used to understand how the product is achieving the speci- fication. The methods and models used in the conceptual view should discuss the how of the product in conceptual terms. The lifetime of the concepts is longer than the specific implementation described in the Realization view.

How do you write a conceptual model?

  1. Choose your topic. ...
  2. Make your research question. ...
  3. Conduct a review of the literature. ...
  4. Choose your variables. ...
  5. Choose your relationships. ...

What are the advantages of a conceptual model?

Concept models close the gap between requirements and planning, between stating the problem and solving the problem. It establishes a consolidated holistic view of what the project is, what it does and the users it will help. It is also a great way to show visually how business goals align with user goals.

What is a limitation of a conceptual model?

Disadvantages of Conceptual Modeling Potential Time Sink: Improper modeling of entities or relationships within a conceptual model may lead to massive time waste and potential sunk costs, where development and planning have largely gone astray of what was actually necessary in the first place.

What is the main difference between a conceptual model and a physical model?

b) a conceptual model represents the shape and form while a physical model describes how a system behaves.

What is the difference between conceptual model and logical model?

The conceptual model is to establish the entities, their attributes, and their relationships. The logical data model defines the structure of the data elements and set the relationships between them.

What is difference between logical and physical design?

The logical design is more conceptual and abstract than the physical design. In the logical design, you look at the logical relationships among the objects. In the physical design, you look at the most effective way of storing and retrieving the objects. Your design should be oriented toward the needs of the end users.

What is the difference between logical and physical models?

The logical model and the physical model are separate models. The logical model enables you to represent business information and define business rules. The physical model enables you to focus on the physical implementation of the model in a database.

What are examples of physical models?

Some of the examples of Physical models:

  • Model airplane.
  • Model car.
  • Model railway.
  • Model rocket.
  • Model house.

What is difference between physical and logical standby database?

Logical standby is different from physical standby: Logical standby database does not have to match the schema structure of the source database. Logical standby uses LogMiner techniques to transform the archived redo logs into native DML statements (insert, update, delete).

How do I start a logical standby database?

  1. Create a Backup Copy of the Primary Database Datafiles.
  2. Create a Control File for the Standby Database.
  3. Prepare an Initialization Parameter File for the Standby Database.
  4. Copy Files from the Primary System to the Standby System.
  5. Set Up the Environment to Support the Standby Database.
  6. Start the Physical Standby Database.

What is the logical structure of a database?

The logical units of database space allocation are data blocks, extents, segments, and tablespaces. At a physical level, the data is stored in data files on disk (see Chapter 11, "Physical Storage Structures"). The data in the data files is stored in operating system blocks.

What is a logical database?

A logical database is the collected information stored on multiple physical disk files and hard drives within a computer. This database provides a structure to house all the accumulated information within the device and determines the relationships between different types of files and programs.

What is a logical structure?

Logical structure refers to the way information in a document is organized; it defines the hierarchy of information and the relation between different parts of the document.

How do you create a logical model?


  1. Step 1: Identify the Problem. ...
  2. Step 2: Determine the Key Program Inputs. ...
  3. Step 3: Determine Key Program Outputs. ...
  4. Step 4: Identify Program Outcomes. ...
  5. Step 5: Create a Logic Model Outline. ...
  6. Step 6: Identify External Influencing Factors. ...
  7. Step 7: Identify Program Indicators.

What does a logical data model look like?

A logical data model describes the data in as much detail as possible, without regard to how they will be physical implemented in the database. Features of a logical data model include: Includes all entities and relationships among them. All attributes for each entity are specified.

Is theory of change a logic model?

The purpose of a Theory of Change is that it works to identify why your activities and interventions will create the outcomes it will. A Logic Model on the other hand will state what outcomes you expect to occur but not necessarily, why you expect that to happen.

What is the difference between logic model and logical framework?

Difference #1: The ToC gives the 'big picture' and summarises work at a strategic level, while a logical framework illustrate a programme (implementation) level understanding of the change process. In other words, the Logical Framework is like a microscopic lens that zooms in on a specific pathway within the TOC.

What are M&E frameworks?

Note: An M&E framework can also be called an evaluation matrix. ... For many organisations, an M&E framework is a table that describes the indicators that are used to measure whether the program is a success.
