ArticleDirectory Case Analysis Object-Oriented Modeling The main task of object-oriented analysis is to establish an accurate, complete, and consistent System Model Based on your needs. In the object-oriented analysis and design process, the project team obtains an idealized system model by analyzing the functional and non-functional requirements of the software, this model describes what problems we

The previous section describes how to embed and reference A mongodb document. There are still many differences between MongoDB and relational database modeling, because MongoDB supports embedded objects and array types. Two approaches are available for MongoDB Modeling: Embedded (Embed) and Link ). So when will Embed be connected? What kind of relationship is between two entities? The previous section descr

Getting started with database modeling with PowerDesigner (PD) is a powerful database modeling tool. With PD, you can create business models and UML diagrams. Of course, the most important function is database modeling. I plan to explain how to use PD in the following parts. 1. Two important models: Conceptual Model and Physical Model 2. Create a table and a mast

Microsoft's Patterns Practices team has released a new PAG document on threat modeling of web applications. this document describes des a description of the threat modeling process and key concepts, the web application security frame, and templates for creating threat models with samples and repeated throughs. "This guidance presents the patterns practices approach to creating threat models for Web appl

. In this case, we modeled with the simplest embedded document.{name: ' Kate Monster ', id: ' 123-456-7890 ', addresses: [{street: ' 123 Sesame St ', City: ' Anytown ', cc: ' USA '}, {Stree T: ' 123 Avenue Q ', City: ' New York ', cc: ' USA '}]}This modeling approach incorporates the obvious advantages and disadvantages:Pros: You don't need to execute a separate query to get all the address information for a person.Cons: You can't manipulate address i

1. If an object sends a synchronous message, it waits for the other person to reply to the message, and receives an answer before continuing its operation. The object that sends the asynchronous message does not have to wait for the other person to answer the message to continue its operation.2. The deployment diagram describes a hardware node at runtime and a static view of the software components running on those nodes. The deployment diagram shows

Directory Objective Principle Content Summary Preface The previous article described the business Modeling and domain concept modeling in the Data warehouse model design, and then came naturally to the phase of the logical Data Modeling LDM (Logical data Model), which is one of the most important aspects of

with an interface to use the Data warehouse. The best attributes are textual and discrete. The attribute should be real text and should not be a shorthand symbol for coding. You should try to minimize the use of encoding in dimension tables by replacing the encoding with more detailed text attributes. Sometimes when designing a database, it is not certain whether a numeric data field extracted from a data source should be treated as a fact or a dimension attribute. It is often possible to make

First, the concept of a deployment diagramThe so-called deployment diagram, translated into English is Deployment Diagram, which is used to display the system software and hardware physical architecture. From the deployment diagram, we can learn about the physical relationships between software and hardware components and the distribution of the components of physical nodes. The deployment diagram enables y

In emstudio, the concept and content of static modeling come from the UML standard. Therefore, the design capability of static modeling provided by emstudio can fully meet developers' design requirements. However, compared with the UML standard, static modeling in emstudio has two different characteristics: 1.The concepts of classes and entities are consistent.

The SSAS modeling tools available in the SQL Server 2008 R2 database include the SQL Servers Management Studio and business Intelligence Studio, so what is the modeling process? Here's what we're going to introduce, and let's take a look at the SQL Server 2008 R2 database modeling tools and key processes, as well as data mining, permissions, and access interfaces

I. Model 1. Prototype and model prototype refer to the actual object that people care about, study or engage in production and management in the real world. A model is a prototype substitute that constructs a part of the prototype's information for a specific purpose, abbreviated and refining it. The model can be divided into the material model (image model) and the ideal model (abstract model) according to the mode of replacing the prototype. The former includes visual model, physical mod
