The Redo-Log-Buffer is a cache that contains information about changes of data blocks in the database buffer. The Shared Pool is a cache used by all users. The main components of this pool are the dictionary cache and the library cache. The PGA (program global area) is used by a single oracle user process. It contains the user’s context area (cursors, variables etc.
User applications typically interact with inference engines via APIs (application programming interfaces). These APIs normally support selecting reasoning strategies, features, and operations, storing facts and querying the result data from the knowledge base, etc. We have adopted the forward chaining strategy in OntoDiabtetic reasoning (Fig 8). Rules are applied to the asserted facts, and the entailed statements are immediately added to the knowledge base until it reaches the conclusion (inferred fact). The f orward chaining algorithm is given below :- Step 1: Let ‘f’ be a fact that is to be added to the knowledge base.
Jelastic is a single platform that come up with sophisticated features such as high availability and scalability for developers, enterprise businesses and clients. Additionally, Jelastic support the most important programming languages such as Java, PHP, Python and many more. Jelastic supply multi-containers environments in private, public and hybrid cloud. Moreover, the Jelastic cloud is simple to use and manage. The consumers can deploy
They are completely designed and are ready for use without any need for configuration. It is best suited for designs that pull information from the database to a Web application like in e-commerce and data retrieval. Ruby on Rails uses different paradigms as Convention over Congiguration (CoC), Don’t Repeat Yourself (DRY), the Active Record Pattern and Model View Controller (MVC) to organize application programming. The tools necessary to produce a Web application are provided by the framework. The user can access information from a database by connecting programming objects to database tables through Rail’s object-relational mapper, the Active Record Package.
From the File menu in the browser model, select one of the following options as a summary of the model Exports exporting text into a text file, HTML Export to export a summary model for HTML files, Export PMML (supported for IBM DB2 IM models only) to export the model as a prediction model mark-up language (PMML), the software can be used with other PMML compatible. You can also save models produced by choosing Save from the File menu node. For each consistency model, the database generated, IBM® SPSS® Modeler store information model structure, together with reference to this model with the same name that is stored in the database. Server tab displays the model produced a unique key generated for the model, which matches the actual model in the database. IBM SPSS Modeller uses these keys at random to check that this model is consistent.
It uses standardized Internet protocol suite (TCP/IP) to link to other devices worldwide and changes data by packets switching. Hypertext Transfer Protocol (HTTP) is an foundation of data communication for the World Wide Web, which is application of protocol for distributed, collaborative, hypermedia information systems. Whereas World Wide Web is an open source information space where documents or web resources are identified by URLs, interlinked by hypertext links, and can be accessed via the Internet. Hypertext Transfer Protocol is the main access protocol of the World Wide Web, which is mainly used to transfer or exchange hypertext. Internet carries a wide range of information resources.
• ODBC requires manual establishment of the ODBC driver supervisor and driver on all customer machines. JDBC drivers are written in java and JDBC code is naturally installable, secure, and mobile on all stages. • JDBC API is a characteristic Java Interface and is based on ODBC. JDBC holds a portion of the essential component of ODBC. Main Similarity Between JDBC and ODBC The JDBC and ODBC are utilized by the customer side applications to get to various types of databases on server side.
Heery and Anderson (2005) also add some more point about the characteristics of digital repositories. They said that repositories are collections of digital objects and there are several characteristics which differentiate between digital repository and other digital collections. The characteristics mentioned were as followed: a) Content is deposited in a repository, whether by the content creator, owner or third party. b) The repository architecture manages content as well as metadata. c) The repository offers a minimum set of basic services such as put, get, search and access control.
WEB SERVER A Web server is a program that uses HTTP (Hypertext Transfer Protocol) to serve files that form Web pages to users, in response to their requests, which are forwarded by their computer's HTTP clients. Dedicated computers and devices can also be called web servers. The process is an example of the client/server model. All computers that host Web sites must have Web server programs. Primary Web servers include Apache (the most installed Web server), Microsoft Internet Information Server (IIS), and NGNIX (pronounced X engine).
