Portal-oriented Application Integration enables us to look at a multitude of systems both internal enterprise systems and external enterprise systems through an individual user interface or software.An example of POAI is an automobile parts supplier that would like to begin selling parts to retail stores (B2B) using a portal. This portal can enable the retail stores to access catalog data, place orders, and track orders over the internet, directly the parts supplier leverages SAP as its chosen stock control system, and a commonly developed mainframe software written in COBOL/DB2 serves as its sales order system. Data from each system is ... Read More

SOA stands for Service-Oriented Architecture. It is a design pattern that is produced to build distributed systems that deliver services to several applications through the protocol. It is a concept and not defined to any programming language or platform.It is an architectural design in computer software design in which application components support services to other components via a connection protocol, generally over a network. The features of service-orientation are autonomous of any product, vendor, or technology.SOA creates it easier for software components over several networks to work with each other. Web services that are built as per the SOA architecture ... Read More

SOI represents Service-oriented integration. It is represented as integrating computing entities using only service cooperation in a service-oriented mechanism. Service-oriented integration addresses issues with integrating legacy and inflexible heterogeneous systems by allowing IT organizations to provide the functionality locked in current software as reusable functions.The uses for this kind of integration are constant, involving the creation of composite software, or applications that combined the processes and data of several applications. For instance, by utilizing this paradigm, software developers are required to make the interface and insert the application services by binding the interface to some Internet-connected application services as are ...

There are various reasons for using EAI (Enterprise Application Integration) are as follows −Mergers & Acquisitions − Mergers & Acquisitions to be successful needed overnight unification of dissimilar business processes of two or more organizations so that they can work as an individual corporation. EAI is the only solution, which will allow such a rapid integration.E-business − E-business needed connecting of users, provisional and partners across the globe, to form an integrated value and supply chain over the web.Industry Regulation & De-regulation − Opening up of business processes to share information and allow market access requires information to circulate openly ...

EAI represents Enterprise Application Integration. It supports an integrated method to connecting the different elements of IT infrastructure- people, software, platforms, and databases to allow secure, intra and inter-enterprise collaboration.EAI solutions allow an organization to merge business processes internally and externally with business partners to make dynamic environments that provide current and developing business requirements, thereby making a global organization.EAI helps in unrestricted sharing of records and business processes between any connected software or data sources in the enterprise without creating major changes to the software or data structures. EAI combines multiple, freely developed software using incompatible technologies into an ... Read More

There are various tools for the management of data warehouse quality are as follows −Quality DefinitionA definition and quantification of quality are given, as the fraction of performance over Expectance. It is used to define quality as the loss communicated to society from the time a product is consigned. The complete loss of society can be considered as the sum of the producer’s loss and the user’s loss.It is familiar that there is a tradeoff between the quality of a product or service and a production cost and that an organization should discover an equilibrium among these two parameters. If ... Read More

Data Propagation is the allocation of data from one or more source data warehouses to another local access database, according to propagation rules. Data warehouses are required to manage large bulks of data every day. A data warehouse can start with a few information, and starts to increase day by day by constant sharing and receiving from multiple data sources.As data sharing advances, data warehouse management becomes a major problem. Database management is required to manage the corporate information more effectively and in multiple subsets, arranging and time frames. These data resources are required to be constantly updated and the ... Read More

Query optimization is of great importance for the performance of a relational database, especially for the execution of complex SQL statements. A query optimizer decides the best methods for implementing each query.The query optimizer selects, for instance, whether or not to use indexes for a given query, and which join methods to use when joining multiple tables. These decisions have a tremendous effect on SQL performance, and query optimization is a key technology for every application, from operational Systems to data warehouse and analytical systems to content management systems.There is the various principle of Query Optimization are as follows −Understand ...

Bayesian classifiers are statistical classifiers. They can predict class membership probabilities, such as the probability that a given sample belongs to a particular class. Bayesian classifiers have also exhibited high accuracy and speed when applied to a large database.Once classes are defined, the system should infer rules that govern the classification, therefore the system should be able to find the description of each class. The descriptions should only refer to the predicting attributes of the training set so that only the positive examples should satisfy the description, not the negative examples. A rule is said to be correct if its ... Read More

Data aggregation is a process in which data is gathered and represented in a summary form, for purposes including statistical analysis. It is a kind of information and data mining procedure where data is searched, gathered, and presented in a report-based, summarized format to achieve specific business objectives or processes and/or conduct human analysis.Data aggregation can be implemented manually or through specialized software. The objective of Aggregation is to get more data about specific teams based on specific variables including age, profession, or income.The data about such teams can then be used for website personalization to select content and advertising ...
