....halting the traversal of new pointers entirely. The latter ability (to stop traversal without halting the delivery of records) makes them unlike iterator based relational operators (see [GRAE93] 4.3.1. The Interface Our primitive methods, modelled on Illustra s user defined aggregate interface [ILLU95], can be summarized as follows: STATEINIT Allocates and initializes any internal state. Returns a pointer to this internal state. STATEITER Computes the next stage of the iterative computation, updating the internal state as required. STATEITER may halt traversal, i.e. that no further node ....

A wide range of data managers use slotted pages, including relational and object relational databases (e.g. nearly all IBM relational systems [MOHA93] Illustra [ILLU95], Oracle Rdb [HOBB91, p. 79] as well as object data managers 3 (e.g. ESM [CARE88] O 2 [DEUX90] Papyrus [CONN93] SHORE [CARE94] The advantages of this scheme are discussed in more detail elsewhere [GRAY93, p. 755] Item IDs have a critical property: unlike tuples, item IDs are fixed size. ....

....one stateful computation is the standard aggregate function, COUNT. Other computations actually influence the tree traversal (we briefly described in Section 3. 1 how node entries can be pruned from the search queue) Our new methods are modelled on Illustra s userdefined aggregate interface [ILLU95]. Each iterator consists of four methods. STATEINIT and STATEFINAL perform initialization and finalization, respectively, whereas STATE CONSISTENT and STATEITER implement the computation over the node entries. They can be summarized as follows: STATEINIT allocates and initializes any internal ....

....this approach are EXODUS [Care86] GENESIS [Bato88] DASDBS [Sche90] and more recently Volcano [Gr94] In retrospect, the first approach seems to have been more successful than the second. Extensibility by data types within a fixed data model has made it into commercial systems such as Illustra [Illu95] where one can now buy data blades for various applications. On the other hand toolkits have essentially proven to be dead ends ; this is at least the view of Carey and DeWitt [CaD96] The main reason was that it was too difficult to construct a DBMS using the toolkit; also the tools offered were ....

....systems (OODBMSs) support a range of additional features that appear to meet some of these requirements [18] But they are proven to perform poorly w.r.t. some key DBMS properties and services such as integrity control, backup, and recovery. For these reasons, we have chosen the ORDBMS Illustra [10] for our prototype system, since it claims to possess the following capabilities: It enables the user to define ADTs, composite and constructed data types. It allows the user to define operations on ADTs, composite and constructed data types. It contains a rule system supporting database ....

Benefits of Using ORDMs How can the rich modeling constructs and the corresponding query facilities of ORDMs improve schema definition and query specification In the following, we refer to the schema definitions of a part of our RITA application in Fig. 3 to outline and illustrate the use ....

Thus in a more abstract view the developer has the task to specify to which class a new function belongs. The system can then apply optimization and execution ....

....optimization (see e.g. 18] 36] 37] 38] simply by specifying the sort order as a required physical property for the operator executing the UDF. Then a sort enforcer rule can guarantee this order requirement by putting a sort operation into the access plan if necessary. Informix Illustra [23] supports already optional sorting of inputs for UDFs that have two arguments and return a boolean value. The developer can specify a user defined order for the left and right input of such a function. Obviously this allows to implement a user defined join predicate using a sort merge join instead ....

The Thor database server uses a typesafe language designed for writing extensions [LISK95] the Illustra database server is extended by writing DataBlades, which add support for new data types to the server [ILLU94]. The Illustra server does not currently protect itself from misbehaved DataBlade code, although Illustra is evaluating software fault isolation techniques.

The system can take advantage of information about the underlying representation, but can function correctly at the abstract level. The Illustra DBMS [ILLU94] is a successor to the POSTGRES system developed at the University of California, Berkeley [STON87] It can be extended by adding user written code to implement new data types. This code can be run in either the client process or the server process; if it is installed in the server, there is no ....

....CONSISTENT controls SEARCH. PRIORITY allows SEARCH to traverse the tree in ways other than depth first search. Finally, the iterator mechanism (consisting of three extension methods, STATEINIT, STATEITER and STATEFINAL, that are loosely based on Illustra s user defined aggregate function interface [ILLU95]) allow us to compute functions over the index records encountered during the index traversal. To summarize, HELL95] defines a framework for defining tree structured indices over arbitrary data types, and [AOKI98a] provides a framework for flexibly traversing these indices and computing an ....
