Hierarchical structure for data management

W. R. Henry
1969 IBM Systems Journal  
Direct organization with sequential list structures (D S) is a list string or chain of data segments organized as a direct data structure.  ...  Entry to the chain or list header is via a specific record in the parent list, i.e., the master file. The third or combined approack occurs when the exact list header is unknown.  ...

ScalaGiST provides extensibility in terms of data and query types, hence is able to support unconventional queries (e.g., multi-dimensional range and k-NN queries) in MapReduce systems, and can be dynamically  ...  Nevertheless, Hadoop, an open-source equivalent of MapReduce, has been noted to have sub-optimal performance in the database context since it is initially designed to operate on raw data without utilizing  ...  The index is organized as a tree structure and stored as a sequential file in the DFS (HDFS in this paper). Similar to a normal DFS file, the index file is also partitioned into multiple chunks.  ...

Multi-dimensional clustering for data base organizations

J.H. Liou, S.B. Yao
1977 Information Systems  
A data base structure which combines this new technique and the file Inversion technique Is analyzed.  ...  Associated with this storage scheme Is a new type of Index called multi-dimensional directory. Those keys which determine the record address are jointly indexed by this directory.  ...  Furthermore, if the file is sorted on any single key (as in the case of an indexed sequential file), the target records of multi-key query will usually be distributed over the entire file space.  ...

A standardized smart transducer interface

Elmenreich, Obermaisser
2002 Proceedings of the IEEE International Symposium on Industrial Electronics ISIE-02  
The second case study is an autonomous mobile robot instrumented by a TTP/A cluster that orientates itself via a set of heterogenous sensors and decides, based on this sensor data, which way to go.  ...  The first case study describes a demonstrator with a robot arm that is instrumented by smart transducers and a TTP/A fieldbus.  ...  An IFS file is an index sequential array of up to 256 records. A record has a fixed length of four bytes (32 bits). An IFS record is the smallest addressable unit within a smart transducer system.  ...

Parallel mining of closed sequential patterns

Shengnan Cong, Jiawei Han, David Padua
2005 Proceeding of the eleventh ACM SIGKDD international conference on Knowledge discovery in data mining - KDD '05  
In this paper we develop an algorithm, called Par-CSP (Parallel Closed Sequential Pattern mining), to conduct parallel mining of closed sequential patterns on a distributed memory system.  ...  Moreover, it employs a technique, called selective sampling, to address the load imbalance problem. We implement Par-CSP using MPI on a 64-node Linux cluster.  ...  Each slave processor outputs the closed sequential patterns in a file. The total closed sequential patterns are simply the concatenation of these files.  ...
