4-6-1 Variable-Length Records The record length for directly accessed les is xed because of the mapping from a record key to a slot number in the le area If a direct- le organization is desired for its other features, either of two constructs will add variable-length record capability When buckets are used, variable-length records can be accommodated in the buckets The search within a bucket becomes more complex The use of a record mark as shown in Fig 2-11 enables serial searches through the bucket Some disk hardware allows the channel or controller to locate a speci c record on a track; this can cost considerable gap space but reduces the software needed to read through blocks in order to identify the marks If the bucket search time cix is a problem, one of the schemes used to structure index blocks (Sec 4-2-2) may help If an over ow from the bucket occurs because of the insertion of many records that were longer than the expected average, the existing-collision management mechanism can be invoked On the other hand, when the records in a block are shorter than average, over ow resulting from collisions due to hashing will be deferred The use of buckets for variable-length records works best if R B When pointers are used to mark records, as shown in Fig 4-29, over ow chains can be maintained using these same pointers In Sec 3-5 over ow chains were used to manage clusters occurring because of insertion and deletion Deletion of variablelength records is best accompanied by a rearrangement of the records remaining within the block to avoid space fragmentation

Indirect Accessing In this method, a small le containing a list of pointers is accessed directly; the selected entry in this list indicates the location of the actual record The organization of the goal data le may be a pile or another organization type chosen according to other requirements placed on the le The pointer-list resembles the lowest level of an index, but the position of the entries is determined by the key-to-address transformation algorithm, so that the list is not suitable for serial searching The bene t of the direct le, that only one block has to be fetched to locate a record, is lost, but two accesses will provide access to any record which is not in an over ow area The simple pointer-list can have a high fanout ratio, because no key is required if collisions are handled after accessing the main data records The main le will use linkages to chain colliding records The alternative is to place the data keys also into the pointer-list entries Now access e ciency is improved for colliding and missing records The keys of over ow entries due to collisions will then also be placed in the pointer-list using openaddressing techniques The associated record is itself placed in the main le as before If the pointer-list is kept using bucket techniques, a copy of the key is required in the pointer-list to identify the entry These buckets will have many entries, so that techniques to increase the speed of searching through the bucket are desirable A binary tree seems ideal for this purpose; its pointers can be used for locating child entries or goal records
