Services
Overview of the currently implemented censhare services and their dependencies in the censhare Server. Detailed technical documentation of the censhare Application Server and its application modules can be found in the censhare Server API documentation.
Introduction
The censhare Server is distributed with several application modules. It's not necessary to develop application modules. But due to the modular design, it is possible to implement fast and efficient solutions in the area of content production and content management. The censhare services provide basic functionality, for example:
Database connectivity
Embedded database (used as a fast search engine)
Remote services (remote servers)
Asset management (check-out, check-in)
Image conversion
and a lot more ...

| Database Query (XMLQueryService) | This service implements a procedure for processing data of a relational database over XML. It allows a query and update of data over XML. | DatabaseService | |
| DataObject | Required to persist changes in the database. | CommandService, DBTransactionManagerFactory, XMLQueryService (Database Query) | |
| DataObjectQuery | Similar to Database Query (XML QueryService) but returns objects. | DatabaseService, DataObjectService, CacheService | |
| DBTransactionManagerFactory | Creates (database) transactions. | none | |
| This service implements the E-Mail functionality within the server. It controls sending of notification E-Mails after it was triggered by an event and it is also responsible for receiving and sending of assets. | none | ||
| Embedded Database (AssetStore) | This service is used as upstream database for search and read. | CacheService, DatabaseService, AssetManagementService | |
| Event | This service implements event registration and notification for other services and modules. For example, it allows scheduled processing of XML commands. For example, events will be generated at the asset check-in of a new version or a workflow state change. | none | |
| Execution | This service is necessary for the invocation of 3rd party software (command line) for automating external processes. XML commands control external applications and processes. | none | |
| Filesystem (FileFactory) | This service administrates the known file systems of the server. This service is responsible for the server to client and server to server file streaming. | CacheService | |
| FTP | This service implements an interface to an embedded FTP server. With this service, it is possible to configure FTP accounts within the server. FTP users must have a permission key "ftp_access_all" set. | none | |
| Fulltext Search (deprecated) | This service was necessary for indexing and finding database content in censhare version 3. | DatabaseService | |
| HTTP Server | This service is used for soap and rest services. | CacheService | |
| Image | This service controls all kinds of image data processing. It implements the interface between the server and 3rd party tools like Helios, ImageMagick, and Ghostscript to create asset previews or to convert images. | FileFactoryService, CLIService | |
| Import | This service is necessary for importing data from external systems. For example, it watches a hot folder input directory for new files, check file names with regular expressions and trigger various actions. | none | |
| Inverted Index | This service is used for TranslationMemory and Dictionary. | none | |
| Kernel | Contains the internal services of the application server. For example, required for the status diagrams. | none | |
| LDAP | This service implements the interface to external LDAP/Kerberos and other ticket-based systems. | none | |
| Online channel command service | This service implements the interface from the censhare OnlineChannel to the censhare server. E.g. for creating assets. | This service depends on all services that are used. | |
