Abstract: In one embodiment, a method includes receiving an unstructured data record and parsing the unstructured data record to determine a characterization of the unstructured data record. The characterization includes determination of: a number of fields, a length for the fields, and an order of the fields as stored in the unstructured data record. The method also includes obtaining a first key pair that includes a primary key-name associated with a first key-value and hashing at least the first key-value to obtain a hash value. In addition, the method includes updating the unstructured data record to include the hash value as an indexing key thereby creating a modified data record. Also, the method includes storing the modified data record in a structured database. Moreover, the method includes updating an index of the structured database to include an entry for the modified data record, the entry including the hash value.

Abstract: In one embodiment, a method includes receiving a request to perform an update on a base data set in a record-oriented file system, wherein one or more affected records within the base data set are modified by the update. Affected alternate index (AIX) records corresponding to the affected records are located, and individual record-level locks are acquired on each affected AIX record. Each of the affected AIX records is updated according to the update after acquiring the individual record-level locks on each of the affected AIX records.

Abstract: In one embodiment, a method includes receiving a request to perform an update on a base data set in a record-oriented file system, locate all alternate index (AIX) records for the base data set, each AIX record including an alternate key field along with one or more relative byte address (RBA) values when the base data set is an entry sequenced data set (ESDS) or one or more primary keys when the base data set is a key sequenced data set (KSDS). Each RBA value/primary key corresponds to one record in the base data set. Individual record-level locks are acquired on each affected AIX record that includes alternate key field values and/or RBA values that are modified by the update. The affected AIX records may be updated after acquiring the individual record-level locks on each of the affected AIX records. Moreover, the affected AIX records may be updated in parallel with updating of unaffected AIX records, thereby greatly increasing performance.
