#Secure Index Architecture The whole project use MVC, a useful design pattern. M mean model, database related codes are in this layer. V means view, it is the user interface. C means controller, the logic layer. Detail information about every layer(including source files) is below: ##V - view *main.cpp: the enter point of whole project, it provide a command interface for user. ##C - controller, core codes of secure index are in this layer *secure_index.cpp: define core algorithm of secure index search, including Kpriv, ToopDoor, BuildIndex, BuildIndex for occurence search, file encryption, file decryption. Detail info please refer to the source code. *document.cpp: define a document structure. *command.cpp: interface for main.cpp, all user input commands are here. *secure_index_service.cpp: the interface between controller with model. ##M - model, database access layer *db_conn_pool.cpp: initiation a database connection pool. *db_adapter.cpp: access database. *config.cpp: database connection configuration. ##Guide for source codes Please follow these steps to read the code: 1Read main.cpp, to understand how mand commands are provided. 2Read command.cpp, to find the command definition. 3Read secure_index_service.cpp and secure_index.cpp(the two important file), to understand secure index algorithm. 4Read db_adapter.cpp, to understand database related operations.
