【正文】 數(shù)據(jù)結(jié)構(gòu)，模塊，進(jìn)程等設(shè)計(jì)實(shí)體間的關(guān)系。 Running Design 運(yùn)行設(shè)計(jì)This section describes how the modules and the processes of this design level cooperate to perform the functional requirements of the system. MSC, transaction diagrams, Structure charts can be used to represent the running procedure. Note: All the functional requirements in SRS should be covered in the description. For Level 2, Function specification of the module to be deposed should be covered.本章節(jié)描述本層設(shè)計(jì)的各個(gè)模塊和進(jìn)程是如何配合完成系統(tǒng)的功能需求. 可以用消息序列圖, (交互)事務(wù)圖, 結(jié)構(gòu)圖等進(jìn)行描述, 可以按照處理過程進(jìn)行分節(jié)描述, 要注意的是描述的內(nèi)容應(yīng)該涵蓋所有SRS文檔的功能需求, 對于二級設(shè)計(jì)來講, 就是要涵蓋分解對象模塊的功能規(guī)格 Data Dependencies數(shù)據(jù)依賴關(guān)系This section describes relationships among data stores。ER diagram can be used to represent dependences.依賴關(guān)系描述可以使用ER圖。本節(jié)描述軟件系統(tǒng)中設(shè)計(jì)實(shí)體(如子系統(tǒng)，模塊，進(jìn)程）的接口.Interface files, parameter tables can be used to describe Interface.接口描述可以使用接口文件，參數(shù)表。 Module/Subsystem Interfaces模塊/子系統(tǒng)接口This section describes interfaces of Module/Subsystem Interfaces。1. Interfaces Provided by Module/Subsystem 1 模塊/子系統(tǒng)1提供的接口For interface function, following format should be used:Interface 1:Format:Input:Output:Return: Describes the return value of the functionDescription: Describes the objective of the interface.對于接口函數(shù)，可以采用以下形式描述：接口1：形式：輸入：輸出：返回：描述返回什么。 Process Interfaces進(jìn)程接口This section describes interfaces of process。1. Process 1 Description進(jìn)程1描述The interfaces between the processes describe the shared memory, protocol data and messages, etc.進(jìn)程間的接口主要是描述一些共享內(nèi)存，協(xié)議數(shù)據(jù)，消息等。This will be repeated for each module as follows (Same as Level 1). The detailed suggestions are also the same as Level 1.對每個(gè)模塊重復(fù)使用下述的格式(和一層設(shè)計(jì)一樣)。該節(jié)的標(biāo)題可以適當(dāng)更改 Deleting MIB Table Item MIB表項(xiàng)的刪除Steps to delete a table item. The title of this section can be modified.刪除表項(xiàng)的動作步驟. 該節(jié)的標(biāo)題可以適當(dāng)更改 Modifying MIB Table Item MIB表項(xiàng)的更改Steps to modify a table item. The title of this section can be modified.修改表項(xiàng)的動作步驟. 該節(jié)的標(biāo)題可以適當(dāng)更改。對每個(gè)屬性，詳細(xì)描述其數(shù)據(jù)庫、數(shù)據(jù)大小、特定約束。 ER diagram 實(shí)體關(guān)系 圖This section should display the ER diagram for all the entities listed above. 本節(jié)描述關(guān)于上節(jié)提到的所有實(shí)體的ER圖3 Detailed Design 詳細(xì)設(shè)計(jì)This section should focus on the description of the detailed design of the software entities that are a part of the software being described by the HLD Specification。 Module 1 Detail Design 模塊1詳細(xì)設(shè)計(jì)Describe data that defined or used in the module, including:Simple data . global variable, constant or macro within the module。Describe plex data from subsection 2, such as structure, union。描述在本模塊中定義和使用的簡單變量、常量、宏；Describes simple variables, constants used or defined in this module。The description of data structure should follow the format below:Data Structure Description: Describing the usage of the data structureData Structure Definition: Defining the data str
