• OLTP https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html Batch processing Databases Batch processing is also used for efficient bulk database updates and automated transaction processing, as contrasted to interactive online transaction processing (OLTP) applications. The extract, transform, load (ETL) step in populating data warehouses is inherently a batch process in most implementations. 1 https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html Enterprise resource planning Disadvantages 1 Due to ERP's architecture (OLTP, On-Line Transaction Processing) ERP systems are not well suited for production planning and supply chain management (SCM). https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html Database normalization Denormalization 1 OLTP applications are characterized by a high volume of small transactions such as updating a sales record at a supermarket checkout counter https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html Online analytical processing The term OLAP was created as a slight modification of the traditional database term OLTP (Online Transaction Processing). 1 https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html Online analytical processing - Aggregations 1 It has been claimed that for complex queries OLAP cubes can produce an answer in around 0.1% of the time required for the same query on OLTP relational data https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html ROLAP While ROLAP uses a relational database source, generally the database must be carefully designed for ROLAP use. A database which was designed for OLTP will not function well as a ROLAP database. Therefore, ROLAP still involves creating an additional copy of the data. However, since it is a database, a variety of technologies can be used to populate the database. 1 https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html Operational system - Synonyms Sometimes operational systems are referred to as operational databases, transaction processing systems, or online transaction processing systems (OLTP). However, the use of the last two terms as synonyms may be confusing, because operational systems can be batch processing systems as well. 1 https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html Online transaction processing 1 OLTP has also been used to refer to processing in which the system responds immediately to user requests https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html Online transaction processing - Requirements 1 In large applications, efficient OLTP may depend on sophisticated transaction management software (such as CICS) and/or database optimization tactics to facilitate the processing of large numbers of concurrent updates to an OLTP-oriented database. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html Online transaction processing - Requirements For even more demanding decentralized database systems, OLTP brokering programs can distribute transaction processing among multiple computers on a network. OLTP is often integrated into service-oriented architecture (SOA) and Web services. 1 https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html Online transaction processing - Requirements 1 Online Transaction Processing (OLTP) involves gathering input information, processing the information and updating existing information to reflect the gathered and processed information. As of today, most organizations use a database management system to support OLTP. OLTP is carried in a client server system. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html Online transaction processing - Benefits Online Transaction Processing has two key benefits: simplicity and efficiency. Reduced paper trails and the faster, more accurate forecasts for revenues and expenses are both examples of how OLTP makes things simpler for businesses. 1 https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html Dataflow programming - State 1 Explicit parallelism is one of the main reasons for the poor performance of Enterprise Java Beans when building data-intensive, non-OLTP applications. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html IBM DB2 - History 1 Other enhancements include OLTP-related improvements for distributed platforms, business intelligence/data warehousingrelated improvements for z/OS, more selftuning and self-managing features, additional 64-bit exploitation (especially for virtual storage on z/OS), stored procedure performance enhancements for z/OS, and continued convergence of the SQL vocabularies between z/OS and distributed platforms. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html IBM DB2 - History 1 DB2 pureScale is a database cluster solution for non-mainframe platforms, suitable for Online Transaction Processing (OLTP) workloads https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html IBM DB2 - Competition DB2 pureScale is a shared-disk database cluster solution that is ideal for high-capacity Online Transaction Processing (OLTP) workloads 1 https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html OLAP The term OLAP was created as a slight modification of the traditional database term OLTP (Online Transaction Processing). 1 https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html OLTP The term is somewhat ambiguous; some understand a transaction in the context of computer or database transactions, while others (such as the Transaction Processing Performance Council) define it in terms of business or financial transaction|commercial transactions.[ http://www.tpc.org/ Transaction Processing Performance Council website] OLTP has also been used to refer to processing in which the system responds immediately to user requests 1 https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html Oracle Linux - RHEL compatibility 1 * Unbreakable Enterprise Kernel - based on a later Linux 2.6-series kernel, with Oracle's own enhancements for online transaction processing|OLTP, InfiniBand, and Solid-state drive|SSD disk access, Non-Uniform Memory Access|NUMAoptimizations, Reliable Datagram Sockets (RDS), asynchronous I/O|async I/O, OCFS2, and networking. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html MaxDB - Distinguishing features MaxDB offers built-in hot backup, does not need any online reorganizations and claims to be SQL 92 Entry-Level compatible. One current development goal is zero administration and by this low TCO. It is also fair to expect good online transaction processing (OLTP) performance combined with relatively low hardware requirements. 1 https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html MySQL Archive The engine is not ACID compliant. Unlike OLTP engines, it uses a stream format to disk with no block boundaries. The head of the Archive file generated is a byte array representing the data format and contents of that file. In MySQL 5.1, a copy of the MySQL FRM file is stored in the header of each Archive file. The FRM file, which represents the definition of a table, allows an Archive file to be restored to a MySQL server if the Archive file is copied to the server. 1 https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html Informix 1 IBM has continued active development and marketing of the key Informix products, the current version of which (12.1) forms the basis of several product editions with variation in capacity and functionality. The Informix database has been used in many high transaction rate online transaction processing|OLTP applications in the retail, finance, energy and utilities, manufacturing and transportation sectors. More recently the server has been enhanced to support data warehouse workloads. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html Windows Server 2003 - Windows Storage Server 1 Windows Storage Server 2003 can also be used to create a Storage Area Network, in which the data is transferred in terms of chunks rather than files, thus providing more granularity to the data that can be transferred. This provides higher performance to database and OLTP|transaction processing applications. Windows Storage Server 2003 also allows NAS devices to be connected to a SAN. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html Adabas - History 1 ADABAS has maintained its position as one of the world's fastest Online transaction processing|OLTP databases, offering 24x7 functioning, Parallel Sysplex support, real-time replication capability, SQL and XML access and other capabilities. Historically, ADABAS was used in conjunction with Software AG's programming language NATURAL, so that many legacy applications that use ADABAS as a database on the backend are also developed with NATURAL as well. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html Essbase 1 In contrast to on-line transaction processing (OLTP), OLAP defines a database technology optimized for processing human queries rather than transactions. The results of this orientation were that Multidimensional database|MDBMS oriented their performance requirements around a different set of Benchmark (computing)|benchmarks (Analytic Performance Benchmark, APB-1) than that of RDBMS (Transaction Processing Performance Council (TPC)). https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html IBM Information Management Software * IBM Informix Dynamic Server|Informix Dynamic Server mdash; high-throughput database server for online transaction processing (OLTP) 1 https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html Firebird (database server) - The Multi-Generational Architecture (MGA) 1 The multi-generational architecture ensures that OLTP and DSS/OLAP operations can be run simultaneously without the delays caused by locking mechanisms found in other products. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html Column oriented database - Column-oriented systems 1 This is a simplification. Moreover, Partition (database)|partitioning, Index (database)|indexing, caching, views, OLAP cubes, and transactional systems such as write ahead logging or multiversion concurrency control all dramatically affect the physical organization of either system. That said, online transaction processing (OLTP)focused RDBMS systems are more roworiented, while online analytical processing (OLAP)-focused systems are a balance of row-oriented and column-oriented. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html Column oriented database - Benefits In practice, row-oriented storage layouts are well-suited for OLTP-like workloads which are more heavily loaded with interactive transactions. Column-oriented storage layouts are well-suited for OLAP-like workloads (e.g., data warehouses) which typically involve a smaller number of highly complex queries over all data (possibly terabytes). 1 https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html SAP HANA - History 1 SAP HANA originates from developed or acquired technologies, including TREX search engine, an In-memory database|in-memory column-oriented DBMS|column-oriented search engine, P*TIME, an in-memory OLTP database acquired by SAP in 2005, and MaxDB with its in-memory liveCache engine. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html Michael Stonebraker - H-Store and VoltDB 1 In 2007, with researchers from Brown University, MIT, and Yale University, Stonebraker started the [http://hstore.cs.brown.edu/ H-Store] project.

This idea originated in the mainframe market where OLTP|online transaction processing emphasized not just the execution speed of one transaction, but the capacity to deal with massive numbers of transactions. With transaction-based applications such as network routing and web-site serving greatly increasing in the last decade, the computer industry has reemphasized capacity and throughput 1 https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html Oracle Exadata 1 'Oracle Exadata' is a Data warehouse appliance|database appliance with support for both OLTP (transactional) and OLAP (analytical) database systems. https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html Versant Object Database - Performance One of the candidates considered was Transaction Processing Performance Council|TPC-E, which was supposed to be the new OLTP standard database benchmark with new complex models aimed at being representative of today’s computing environment 1 https://store.theartofservice.com/itil-2011-foundation-complete-certification-kit-fourth-edition-study-guide-ebook-and-online-course.html Versant Object Database - Applications 1 Usually the “best kind of application” to use a Versant database are those applications requiring an application specific database of an OLTP nature.
