This enables the developers to centralize application logic in the database. Oracle provides powerful functions and sub-queries in its SQL statements. Developers can distribute systems by database links, materialized views and distributed queries. This feature saves much cost for developing distributed systems and applications. And there's a lot of features integrated with Oracle, compare to other database it is very expensive but it is extremely powerful and fast.
DB2 is a relational database system developed by IBM Corporation. It has been designed for use on large mainframe computer systems running on a variety of platforms including SunOS, Solaris, Linux, Windows 95/98/NT/2000 and HP-UX. DB2 supports many variety of platforms, standards and packaging options to deliver the needs of every business DB2 database delivers a flexible and cost-effective database platforms achieving demand on business applications. It further leverages the resources with broad support for open standard and popular development platforms include J2EE and Microsoft.NET. The primary internal database scripting language for DB2 are SQL/PL, Java and C. SQL/PL is compiled which means it performs better whereas Oracle's PL/SQL is interpreted. In terms of command, DB2 is much simpler to create, monitor, backup and restore database. It is portable database because DB2 exist everything from PDA through PC, midrange server, a cluster up to mainframe. According to an Online article on DB2 v Oracle Quick Comparison Guide,
DB2's optimiser is considered better than Oracle in deducing the most efficient access plan. Oracle allows you to overrule the optimiser by using hints, however, whereas, DB2 does not have this. The disadvantage of relying on hints is that they only produce the most effective access plan for a known volume of data. DB2's total cost of ownership is much lower than Oracle. The reason for this is that IBM don't bundle in additional, little used, functionality in to their main product and charge you...

Microsoft Access, Microsoft SQL Server, DB2, and Oracle are four of the most important and widely used database management systems (DBMS) in use in today's information technology field. This paper compares the four DBMS in terms of ten major factors: 1) price, 2) platform compatibility, 3) support services, 4) support for ERP and CRM high-end systems, 5) open or proprietary, 6) Ease of integrating information with other databases 7) support
Database Concepts Compare and contrast Microsoft Access, Microsoft SQL Server, DB2, and Oracle database programs Providers: Microsoft Corporation provides Microsoft Access and SQL Server, Oracle by Oracle Corporation and DB2 is a product of IBM. Brief about each: MS Access: Microsoft Access is a database, which comes bundled in Microsoft Office Products. Access is fully compatible with Active Server Pages (ASP) scripting. Database programs such as Access (sometimes called Relational Database Management systems or
With optimistic concurrency control, the database checks resources to determine if any conflicts have occurred only when attempting to change data. If a conflict occurs, the application must read the data and attempt the change again. Pessimistic concurrency, on the other hand, control locks resources as they are required, for the duration of a transaction. Unless deadlocks occur, a transaction is assured of successful completion 5.5 Audit Tracking Although auditing does
MS Project Microsoft Project Review Microsoft began development of its project software at the turn of the century (around the year 2000). The original software package ran from MS Dos and had incredibly limited functionality. However, since its introduction, Microsoft Project has come a long way from its original state. Today's versions of MS Project, such as Project 2010, Project 2013, and now even cloud-based Project versions has a rich list of
