TL;DR: In this paper, a mobile shopping cart that can automatically keep track of objects selected and carried in the cart and provide a customer using the cart information like the total price of the items carried.

TL;DR: System R as mentioned in this paper is an experimental database system designed to demonstrate that the usability advantages of the relational data model can be realized in a system with the complete function and high performance required for everyday production use.

TL;DR: This paper describes the concepts used in the implementation of DBDSGN, an experimental physical design tool for relational databases developed at the IBM San Jose Research Laboratory and illustrates how a system can export a model of its internal assumptions and behavior so that other systems can share this model.

TL;DR: The hot-set model, characterizing the buffer requirements of relational queries, is presented and it can be used by the query optimizer to derive efficient execution plans accounting for the available buffer space, and by a query scheduler to prevent thrashing.

TL;DR: A buffer management algorithm based on a model of database requests is presented based on the combination of a regular pattern of accesses made by a process and the competing requests for buffer resources made by concurrently executing processes.
