Geographic Information System (GIS) can process high-resolution and massive spatial data and is a powerful tool for spatial epidemiological research. In order to enable Chinese researchers to master the basic operations and applications of GIS, the education center of the Institute of Computing Technology of the Chinese Emy of Sciences held a "advanced training course on GIS data processing and modeling" at South China Agricultural University in Guang

progressive division of context can first identify the coarse-grained restriction context, which may contain some nested restriction context. You need to choose whether to use nested or fully isolated methods to define the restriction context. The reason for preference for nested methods is that it can make the architecture more fragmented for better testing. Use of nesting: If all services are managed by one team, the nested structure is more reasonable because the organizational architecture

1. Conceptual Data Model (CDM)Modeling of data and information, using the form of entity-relationship diagram (E-R diagram) to organize data, test the effectiveness and rationality of data design. 2. Logical Data Model (LDM)The model added by powerdesigner 15. A logical model is an extension of a conceptual model, indicating the logical order between concepts. It is a model at the method level. Specifically, the logical model shows the relationship b

Use staruml for modeling Staruml is a professional UML modeling tool and is the first software for beginners because it is free and open-source. Start: 1. Interface introduction: There are four main aspects: toolbar, workspace, browsing area, and attribute area. The structure is as follows: 2. Create a model diagram: UML has a lot of diagrams, and there are

As a GIS professional, I am more accustomed to two-dimensional maps, two-dimensional images or two-dimensional design drawings. However, as we live in a 3D world, modeling for our 3D environment has become the expectation of more and more people. 3D models have more benefits than 2D models. For example, 3D models are more flexible and can provide more perspectives for faster video animation creation. 3D models allow us to perform real-time computing w

In the actual control process in the system, some assertions made during the interaction may be false. If the assertion is found to be false, all messages in the instance sequence diagram are empty, and this situation will not occur. An instance sequence diagram describes a single situation that may

Currently, two common methods of project architecture are transaction scripts and Domain Modeling. Transaction scripts have no architecture. They only use the natural architecture provided by the existing mature technology platform, or such as. NET and J2EE, to provide the transaction scripts and their implementation environments. The transaction script directly develops SQL and GUI, and directly operates the database through SQL In

standard method for 1 to n modeling. Later, we will explain it in three specific scenarios. First, we will refine the n in 1 to n. What is the magnitude of n? How many to dozens? Or how many to thousands? Or thousands? 1) 1 to n (n represents several, or dozens, not too many) For example, each Person has multiple addresses. In this case, we use the simplest embedded document for modeling. { name: 'Kate Mo

Today I borrowed a concise tutorial on the Standard Object Modeling Language (UML Distilled: a brief guide to the standard Object Modeling Language ). Translated by Mr. Xu Jiafu. In general, I feel that a good book is ruined. Those in the beginning of this article are not in the same order. For example, "If someone accidentally falls into my trap and the Controller object ends, I need to shut the rabbit in
