A computer system for synchronizing a mobile device with a remote enterprise database includes a replication database. The replication database is mapped to and maintained as a subset image of the remote enterprise database through a bi-directional replication process. A mobile device gateway server is coupled to the replication database. The mobile device gateway includes a concentrator, which is configured to selectively receive replication data from the replication database, transform the received replication data into a format native to the mobile device and to selectively send the received and transformed replication data to the mobile device. The concentrator is also configured to receive mobile device data, transform and to send the received mobile device data to the replication database. The mobile device gateway server acts as a middle tier between one or more enterprise databases and one or more mobile devices or any network-enabled thin client.

A middle-tier Web server with a queryable cache that contains items from one or more data sources. Items are included in the cache on the basis of the probability of future hits on the items. When the data source determines that an item that has been included in the cache has changed, it sends an update message to the server, which updates the item if it is still included in the cache. In a preferred embodiment, the data source is a database system and triggers in the database system are used to generate update messages. In a preferred embodiment, the data access layer determines whether a data item required by an application program is in the cache. If it is, the data access layer obtains the item from the cache; otherwise, it obtains the item from the data source. The queryable cache includes a miss table that accelerates the determination of whether a data item is in the cache. The miss table is made up of miss table entries that relate the status of a data item to the query used to access the data item. There are three statuses: miss, indicating that the item is not in the cache, hit, indicating that it is, and unknown, indicating that it is not known whether the item is in the cache. When an item is referenced, the query used to access it is presented to the table. If the entry for the query has the status miss, the data access layer obtains the item from the data source instead of attempting to obtain it from the cache. If the entry has the status unknown, the data access layer attempts to obtain it from the cache and the miss table entry for the item is updated in accordance with the result. When a copy of an item is added to the cache, miss table entries with the status miss are set to indicate unknown.

An insulating cup or container (50) and a method of manufacturing it comprises (first embodiment) providing a sidewall blank (12B) having two sections separated by a fold score (15), and a separate insulating sheet (18) (corrugated, ribbed, embossed, foamed, perforated, etc.) which is adhesively fastened to one of the sections. The blank is folded in half along the fold score, to form a three-layered assembly with the insulating sheet in the middle. To reduce the thickness of the seam, the blank is thinned in the area adjacent a fold score prior to folding. The assembly is wrapped around a mandrel to bring the outer edges together at a side seam (22S) to form a sidewall 12. The side seam is sealed, the bottom is added, and the rim is formed. In a second embodiment, the insulating layer can be a coating on one or both of the sections of the two-section starting blank. In a third embodiment, the insulating section (40) is integral with, and extends from, one edge of the starting blank. It is folded over first to form the middle layer of the wrappable assembly. The width of the seam is reduced while being reinforced at the top by using edge tabs, thereby providing a rounder cup and one which is less susceptible to top leakage due to an unsealed top curl. One tab extends at the fold line from the top edge of one section, which is shorter, to the top edge of the adjacent and higher section. A second tab extends out from the top of the side edge of the higher section so that it overlaps and seals the other tab when the cup is formed.

An enterprise component-based software development system includes a component platform with a number of development tools and services that enable rapid and straightforward development of component-based systems. The component platform describes a middle tier architecture for a multi-tier, multi-user application. It defines the services and facilities as well as the structure in which components can execute. It helps to provide an extensible platform for the construction, management and execution of component-based software. A messaging platform facilitates communication between different computers. When a component requests a service from another component, the request is serialized and encoded into a platform-independent language such as XML. The XML-encoded message is transmitted over the Internet using an HTTP protocol to a receiving computer, which validates the message and delivers it to the component providing the requested service. Since XML is a platform and architecture independent language, requests processed in this way can be used by a wide variety of disparate systems.

A middle-tier Web server with a queryable cache that contains items from one or more data sources. Items are included in the cache on the basis of the probability of future hits on the items. When the data source determines that an item that has been included in the cache has changed, it sends an update message to the server, which updates the item if it is still included in the cache. As disclosed, the data source is a database system and triggers in the database system are used to generate update messages. The data access layer determines whether a data item required by an application program is in the cache. If it is, the data access layer obtains the data item from the cache; otherwise, it obtains it from the data source. The Web application programs use global data set identifiers to identify data sets, while the cached data sets are identified by local data set identifiers. The cache receives a query context of global data set identifiers, determines whether the data sets of the query context are cached, and if they are, provides the local data set identifiers for the query context to the access layer, which then uses the local data set identifiers to query the cache.
