Data Testing Model Diagram Example
For example, using an incorrect node label in a test may lead you to believe that the data doesn't exist in the graph. At this point, you can also start considering the scalability of your graph and how performant it would be if you write the same queries in a graph with millions of nodes and relationships.
Model-based testing is nothing but a simple testing technique in which we get different test cases that are described by the model. In this type, the test cases are generated via both online and offline test case models. Data flow diagrams DFDs These show how data moves through a system with an emphasis on the entry, processing, and

They help us understand the tables, their fields and how fields in one table relate to fields in other tables in the DB system.
The data flow diagram is used to model a perspective of the system that can be easily understood by the non-technical users as the symbols and syntax used in DFD are simple. It is used by the analysts, customers, and developers to understand the requirements more clearly mainly during the requirements gathering and analysis phase of the SDLC .
Logical data model ER, dimensional, and object-oriented modeling Specifies data structure, attributes, and constraints without focusing on storage. Example A star schema outlining a Sales fact table with dimension tables like Time, Product, and Customer. Physical data model Dimensional, object-oriented, and NoSQL modeling
Here's how our entity-relationship model might look in an ER diagram In this diagram Headers names above lists are entities. A simple example is the quotSalesquot data model, commonly used in retail businesses. Example of a Fact table. A Sales table is very common example of a Fact table. This example contains SalesID Primary Key
6. Data-Flow Testing Data-flow models are used to analyse the flow and transformation of data within a system. Test cases focus on verifying the correct flow of data through the system, including data processing and storage. It's particularly useful in data-intensive applications like databases and data processing systems. 7. Scenario-Based
diagram for where we see four states and about nine transitions. The state diagram helps us understand the web-based system more easily. It also helps us in asking questions about newpossible transitions. Negative test scenarios can also be tested using the State Diagram. For example, the state diagram below depicts that a user on the
Covered system is expandable - plug-ins, scripts. See example 4. In the database there are complex calculations or complex relationships. See example 6. DDT can be used to stabilize the system, in which difficult-fixable bugs may arise, and to organize the competent regression testing see examples 3 and 5.
Example of Model-Based Testing. Unified Modeling Language UML testing UML diagrams, use case diagrams, sequence, activity, etc., model the system's interactions and behavior. You can generate test cases based on these UML diagrams to validate that the software can adhere to set expectations. Data-flow testing Data flow models
