Abstract: Techniques for integrating data from multiple data sources with a transaction-related workflow are provided. The disclosed techniques include, in response to determining that a contact record was retrieved from a second data source, concurrently with the assigning of a role to the contact record, instantiating a version of the contact record in a first data source using data obtained from the second data source.

Abstract: Technologies for supporting customizations of a database schema are disclosed. In an embodiment, an application programming interface includes an aliasing component and a mapping component, which cooperate to constrain modifications to front-end software to the aliasing component and to constrain modifications to back-end database schema to the mapping component.

Abstract: A method, system, computer program product, and related business methods for phased rollout of an upgraded version of a web-based business information system are described. URLs associated with client requests remain the same even where the target subscriber accounts have been upgraded. Client requests for both upgraded and non-upgraded accounts are received by a common set of web servers. Client requests representing external entry points are trapped, and the receiving web server accesses a login router database to determine whether the target subscriber account is upgraded or non-upgraded, and then transfers the request to an appropriately-versioned application server. Application server sets are mapped to database sets according to system version, allowing the upgraded system database schema to be substantially different than the non-upgraded database schema. An early adopter program business method leveraging the abilities of such web-based business information system is also described.
