Cached information that includes multiple network addresses is delivered in a manner that changes the order of the network addresses each time the cached information is delivered to a client, thereby achieving load balancing in a manner that reduces network traffic and improves system performance. In the preferred embodiments, the user defines a minimum time to live (TTL) and one or more order change criteria. When a query is made to a DNS, the DNS returns an answer that includes a time to live (TTL). This answer may be stored in a cache, and may include multiple network addresses. If the TTL for the answer received from a DNS is less that the minimum TTL, the TTL for the answer is set to the minimum TTL before storing the answer in the cache. When a query may be satisfied by a cached answer that includes multiple network addresses, a cache mechanism delivers the multiple cached network addresses in an order determined by the one or more order change criteria if the TTL for the cached results is a positive number. In this manner load balancing can be achieved while still benefitting from the performance enhancements of caching DNS query results.

A data warehouse design that combines data from multiple source ledgers or modules is constructed and from that an associated, single physical Star or Snow-Flake schema and OLAP hyper-cube analytic structure is generated to enable cross-functional analysis of any those multiple source ledgers or modules. The step of constructing the data warehouse or the step of generating the associated OLAP cube is achieved without significant human intervention using software. The present invention is based on the insight that the technical bias against generating individual data marts and OLAP cubes from multiple source ledgers is not well founded. Previously, the norm has been to generate a single physical OLAP cube for each individual ledger—hence one for the General Ledger, a further one for sales order processing etc. This prior art approach makes cross functional analysis multiple source ledgers and sub-ledgers difficult since it requires the creation of a further level of physical or virtual cubes across multiple physical cubes and complex querying. This is no longer necessary with the present invention.

A distributed query system includes a distributed collection of dynamically created compiled queries. As each client submits a query, a parameterized query skeleton is identified, which identifies the general form of the query, and the parameters associated with the particular query. If a compiled form of the skeletal query is available within the distributed system, it is executed with the parameters of the current query. If the compiled form of the skeletal query is not available within the distributed system, a compiled form is created, and the location of this compiled skeletal query is stored for subsequent access by this client, or other clients. The executable compiled skeletal queries may be stored at each client system, in a commonly available server storage system, or within one or more database servers. A routing system may be provided to efficiently route parameterized queries to the appropriate location(s) of the compiled skeletal query.

To use the memory space more effectively, cell memory can be shared by an input link and all output links. To prevent one flow from occupying the entire memory space, a threshold may be provided for the queue. The queue threshold may accommodate the RTT delay of the link. Queue length information about a downstream switch module may be sent to an upstream switch module via cell headers in every credit update period per link. Cell and/or credit loss may be recovered from. Increasing the credit update period reduces the cell header bandwidth but doesn't degrade performance significantly. Sending a credit per link simplifies implementation and eliminates interference between other links.

Tubular baseball bats comprised of an elongated handle portion and a striking or barrel portion wherein the barrel portion has variable stiffness along its length. One such bat has a circumferential low cost, low weight stiffener generally located in the sweetspot area designed to increase radial stiffness in a controlled manner which results in decreasing the bat performance to meet a changed bat performance standard and can be applied at low cost to both used field returned bats and bats being newly manufactured.

Various timing schemes can be used to synchronizing display functions with touch and/or stylus sensing functions for devices including a variable refresh rate (VRR) display. In a continuous-touch mode, for example, extended blanking can result in frame judder due to mismatch or latency between reporting of sensing data and the display.
