Narrowcast AdministratorNarrowcast Administrator provides a graphical environment for configuring servers, developing services, maintaining applications, and administering users. The modular architecture of Narrowcast Server allows custom modules to be integrated directly into the Narrowcast Administrator user interface.Delivery EngineThe Delivery Engine comprises several components that work together to define and store object definitions, run services, and track service execution. These components include:The Distribution Manager (DM), which manages and directs service execution by distributing service workload to available execution enginesThe Execution Engine (EE), which performs the work of gathering service content, formatting it, and delivering it to devicesThe Micro Strategy Logging Server, which provides an event and statistics routing infrastructureThe Object Repository, which stores the objects used to define a Narrowcast Server system and the services in itThe Subscription Book Repository, which stores all subscription data, including end users, addresses, personalization, and subscription setsAdditional components contribute to processing information for service execution. These components enable integration with other systems such as MicroStrategy Intelligence Server or email servers. These components include:Information sources, which can retrieve personalized information, such as grid and graph reports, from local or remote systems such as a MicroStrategy Intelligence Server.Document formatters, which transform raw data provided by information sources into formatted messages. The default configuration for Narrowcast Server supports text, HTML, and Excel output formats.Information transmitters, which connect to local or remote systems such as email (SMTP) servers, shared network locations, shared network printers, SMS (messaging) centers, and wireless application servers to deliver formatted content to end users. SequeLink SequeLink is a complete solution for configuring and managing data access across any number of data stores, operating systems, and deployment options. SequeLink provides a universal client for ODBC and JDBC, and provides a centralized console for configuring and managing data access from a single point of control. SequeLink creates two NT services: SLAgent 54, which is the Administrator, and SLSocket54, which is the Server.

Creating a serviceYou can create a service in two ways: using the Service Wizard or using the Service Editor. The Service Wizard is used in the steps in this chapter to create and send sample services. However, the Service Editor provides a slightly different set of functionality, so it is important to be aware of both of these tools:1.Service Wizard: The Service Wizard steps you through creating a new service, including defining the content of the messages sent by the service, creating subscriptions, and defining an execution schedule. The Service Wizard allows you to create different content for each information transmitter defined in your system. For example, mobile devices can be sent short plain text messages while email clients such as Microsoft Outlook can be sent rich, graphical HTML messages with Excel attachments.2.Service Editor: Use the Service Editor to design a service for more than one locale. For example, a service made available to a multinational user community might include several different publications, each publication containing content in a different language to support the set of users who prefer that language. The Service Editor provides more flexibility than the Service Wizard by allowing you to add as many publications as you need to support your Multilanguage user community.
