Automating process controls to ensure systems correctly process and record information. (FFIEC IT Examination Handbook InfoBase - Design Phase., n.d.). Quality management techniques that improve quality assessments include error detection, process control, and process design. These processes detect missing values, improve recurring errors, and help optimize effeciency. (Even, A., & Shankaranarayanan

sometime some transaction need to delete the data items from database and create the data items into database. Such type of transactions show high impact on concurrency control. So, we are analyzing how those transaction bias the concurrency control in database management system. Introduction: The basic problem of concurrency control is sharing the data in database at a time by many numbers of users. Due to many users accessing data at a time which causes to produce the undesirable output

different types of multi-version concurrency control techniques one of those techniques which widely used in the real world is snapshot isolation. It has been used by major database management system to obtain high throughput. It also provides better performance than the serialzability so it’s gained wide acceptance in commercial and open source systems such as Oracle, SQL, PostgreSQL, Interbase, Firebird. Introduction: Snapshot isolation is a multi-version concurrency control that is very popular and intensely

This paper describes the ordinary CDBS is Relation Database System (RDBS), which has the great system for transactions processing and locking. Locking mechanism in DDBS is similar to that in RDBS, but it is more complex because of data distribution and transaction concurrence in distributed database system. state that the Lock table and Two-stage Locking convention (2PL) are utilized as a part of Relation Database Management System (RDBMS) with multi-granularity convention for accessing operation

(MMDBMS) is a framework that manages different types of data potentially represented in a wide diversity of formats on a wide array of media sources. It provides support for multimedia data types, and facilitate for creation, storage, access, query and control of a multimedia database.[w] 4.0 NATURE OF MULTIMEDIA DATA The amalgamation of multimedia data types from numerous sources uniquely characterizes multimedia information systems. The data types found in a typical multimedia database include: 

This is a final research paper for 4568-Distributive Database Systems (MCS-6323) with instructor Mazin Al Hamando. Abstract Distributed database technologies are an emerging market and bound to have a significant impact on data processing in the upcoming years

Database Processing, 13e (Kroenke/Auer) Chapter 9: Managing Multiuser Databases 1) Database administration tasks have to be performed for single-user, personal databases. Answer: TRUE Diff: 3 Page Ref: 396 2) Database administration is more important but less difficult in multiuser database systems than in single-user database systems. Answer: FALSE Diff: 2 Page Ref: 396 3) In general, the overall responsibility of the DBA is to facilitate the development and use of the database system

execution. That is why author think the net result of these trends is that parallel database systems can be run on multi-core platforms. In addition, the author lists the various aspects of the situation like CPU cache performance and memory-resident concurrency management. And the author also offers some solutions for allowed database
