Desenvolvendo web services com oracle em PL SQL: vantagens e desvantagens

Abstract

In organizational environments, it is common to come across heterogeneous applications, developed in different platforms, languages, data structures or other forms of applications. At present, the need to exchange information by corporate structures, internally or externally, is increasingly evident. In this context, when dealing with heterogeneous applications, the exchange of information is difficult. An alternative focused on web environments, is the Web Service, data can be transmitted anywhere in the world, over the network, through a web protocol. Deploying a Web Service starts with the development of methods hich can be written a programming language, and then published on the Web. Access to the methods of a Web Service occurs through an Internet protocol. In this way, communication between heterogeneous systems with the exchange of data files. Files sent and received by the Web Service can be easily interpreted due to the storage format. One of the widely used formats is WSDL, in which parameters and operations are defined in an XML file. One of the alternatives is the implementation through the database itself, and can be implemented in an Oracle database with PLSQL. The present work aims to show a comparison of performance, and the advantages and disadvantages of each Web Service.
