Concurrency Control in Distributed Database Systems PHILIP A. BERNSTEIN AND NATHAN GOODMAN Computer Corporation of America, Cambridge, Massachusetts 02139 In this paper we survey, consolidate, and present the state of the art in distributed database concurrency control.
6/9/1988 · A distributed database consists of a number of sites, each of which is a computer and a facility for storing data. In general, each site has both a transaction server to process queries and updates generated by a user, and a file server to handle data access.
Distributed database is a software that provides on access mechanism that makes the distribution transparent to user whereas the Parallel database system seeks to improve the performance through parallelization of various operations such as loading data, building indexes and evaluating queries by using multiple CPU’s and disks in parallel.
The solution is to handle those databases through Parallel Database Systems, where a table / database is distributed among multiple processors possibly equally to perform the queries in parallel. Such a system which share resources to handle massive data just to increase the performance of the whole system is called Parallel Database Systems.

4/1/2010 · A database that consists of two or more data files located at different sites on a computer network. Because the database is distributed, different users can access it without interfering with one another. However, the DBMS must periodically synchronize the scattered databases to make sure that they all have consistent data.

To achieve the performance requirement, database systems have been increasingly required to make use of parallelism, which fall in one of the two resulting DBMS architecture. These are parallel DBMS and distributed DBMS. A parallel DBMS can be defined as a DBMS implemented on a tightly coupled multiprocessor [3].
Distributed DBMS - Distributed Databases - This chapter introduces the concept of DDBMS. Thus, the overall database of the organization becomes distributed. Need for Sharing of Data − The multiple organizational units often need to communicate with each other and share their data and resources.
• Alongside-the-database method. The data are stored in the distributed database management system (DBMS) and are read in parallel from the DBMS into a SAS analytic process that runs on the database appliance. • Alongside-HDFS method. The data are stored in the Hadoop Distributed File System (HDFS) and are read in parallel from the HDFS.

With the Data Parallel Model, communications often occur transparently to the programmer, particularly on distributed memory architectures. The programmer may not even be able to know exactly how inter-task communications are being accomplished.

Distributed Database Management System (DDBMS) is a type of DBMS which manages a number of databases hoisted at diversified locations and interconnected through a computer network. It provides mechanisms so that the distribution remains oblivious to the users, who perceive the database as a single database. Such distributed database solutions can greatly increase the performance of applications built on infrastructure-limited databases. The GridGain ® in-memory computing platform can be installed between the application and data layers and uploads data from the underlying disk-based RDBMS, NoSQL or Hadoop datastores into RAM.
