...systems; a database is an organized group of files that are related and considered the supporting constructs of a database management system. It is maintained and considered an integral part of most organizations worldwide. The database management system houses a program that enables storage, modification, and extraction of information from a database. In this paper team A will address database the phases of the database life cycle, and provide a conceptual representation for a database system. Team A focused on relational data model utilizing the Oracle database management system. Implementation of a Database System The purpose of the implementation phase is to make the new system available to a prepared set of users. In this phase the construction and installation of the new database system is initiated according to the plan and design that represents all aspects of the organization, including its interactions with the external environment, this requires matching the design requirements with the best available implementing tools and then using those tools for the implementation. There are several basic steps to implementation of a database system. Determine the need, for developing a new system; identifying user needs; developing the contextual and external and internal level schemas; translation of the internal level schema into the actual databases structures that will be implemented in the new system then transferring all of the existing data to the new database.

...ERP Implementation Life Cycle An ERP implementation life cycle refers to the distinct stages in which an organization carries out an ERP implementation. Typically, we advise mid-market manufactures to move through the following seven stages: * Pre-Implementation * Project Planning * Product Education * Design Configuration * Development and Test * Go-Live * Post-Implementation The concept of an ERP implementation life cycle is on the minds of many mid-market manufacturers as this calendar year comes to an end. Many process and discrete manufacturers are heading into active ERP projects in the New Year, and considering what it means to enter into the various phases of an ERP implementation. The Start of the ERP Implementation Life Cycle is Pre-Implementation While it’s tempting to gloss over the preparatory activities that should take place in the “pre-implementation” phase, our team advises manufacturers to take special care in this first phase of ERP implementation life cycle. Tasks that are part of pre-implementation form a solid foundation for the ERP project. We advise that manufacturing companies carefully manage this phase, because success at this early stage increases the likelihood of success at “go-live.” Typical best practices take place in the following areas: * Vendor Due Diligence - These are tasks found at the end of the technology evaluation cycle, involving vendor due diligence, site visits, ERP vendor customer references...

Moreover, this chapter will also present the computer programming language,, and methodologies used in the development of the system. 2.1 Introduction The basis of the development of a completely computer-based information system is very important. Such features that are comprise hereto include the database system, it consist of the Database Management System (DBMS) which is designed to manage all databases. The database is the most important structure of an information system. In this chapter, the theories used in the development of the proposed system will be discussed. In line with this is the database system, which uses a normalized database to encapsulate the constructs of a data model, to eliminate data redundancy, organized data effectively and to trim down irregularities during data operations. Another is the used of the Third-Generation Programming Language, also known as 3GL Computer Language like Visual Basic 6, a further advanced language to enable a more user-friendly interface in the system. Correspondingly, with the incorporation used of Structured Query Language or SQL to create, modify, retrieve, and operate data. other nodes is also the Graphical User interface or GUI to utilize the graphical images and text to signifies information for the end users. Indeed, GUI will aid the user to have an ease in navigating modules of the proposed system. Generally, the Systems Development Life Cycle or SDLC is the...

...Executive summary Continued database growth, long-term data retention regula- tions and storage requirements are increasing operational costs. As a result, more CIOs are examining the potential ben- efits of implementing cost-effective strategies for managing data and information throughout its life cycle. Because most of the historical data stored in high-performance application databases is inactive, more companies are realizing the value of database archiving as an essential component in an effective data management strategy. Allowing application data growth to continue can degrade performance, limit availability, increase costs and slow disaster recovery. Yet, archiving complex relational data poses many challenges. Organizations need the capability to archive historical data and safely remove it from the production environment. They also need capabilities to store archives cost-effectively, retain access and dispose of data appropriately to comply with data retention regulations. In short, organiza- tions need an effective archiving strategy for managing application data throughout its life cycle. In searching for the ideal archiving solution, some organiza- tions consider in-house development, but soon realize that the short- and long-term costs do not offset the expected return on investment. Implementing an off-the-shelf archiving solution does offer advantages in faster acquisition and imple- mentation. However, the ideal solution must provide...

...Smith Consulting Database Environment Student Name DBM/380 Date: Instructor name: Smith Consulting Database Environment Smith Consulting’s current employee management system is inefficient involving a one table database, which produces duplication of many attributes throughout the system. The first iteration of database design provided a new version consisting of various one-to-many relationships to link its various modules. There are currently four modules that consist of an employees, jobs, skills, and projects tables. Smith Consulting has many employees filling many jobs descriptions. Furthermore, each job position may encompass many skills. Finally, many employees may be working on many projects. This first iteration of database design provided a database model that is inadequate and requires a return to the database development life cycle (DDLC) to incorporate the needed many-to-many relationships among tables for efficient allocation of human resources in order to better meet company customer needs. An analysis of the database environment has surfaced the various problems and constraints with the current system. This in turn has determined the scope and boundaries for the new system version. An overall objective and supporting objectives provided the needed data specifications, which is depicted in a logical model table and database schema. Database Environment Analysis The current database environment involves a one table database. This current system has various...

...this article, we review and compare several prominent data warehousing methodologies based on a common set of attributes. Online transaction processing (OLTP) systems are useful for addressing the operational data needs of a firm. However, they are not well suited for supporting decision-support queries or business questions that managers typically need to address. Such questions involve analytics including aggregation, drilldown, and slicing/dicing of data, which are best supported by online analytical processing (OLAP) systems. Data warehouses support OLAP applications by storing and maintaining data in multidimensional format. Data in an OLAP warehouse is extracted and loaded from multiple OLTP data sources (including DB2, Oracle, IMS databases, and flat files) using Extract, Transfer, and Load (ETL) tools. The warehouse is located in a presentation server. It can span enterprisewide data needs or can be a collection of “conforming” data marts [8]. Data marts (subsets of data warehouses) are conformed by following a standard set of attribute declarations called...

...1. (a) What is the difference between an intranet and an extranet Intranet is an internal network. It is used by companies to connect their computers on a network. In general, intranet as a network based on TCP/IP protocols belonging to an organization and only the members of the organization can access the network. However, intranet is inaccessible from the outside. Only the members of the corporation with authorized access the network. Like other networks, the Intranet is mainly used to share data, information, resources, company programs, software applications. Intranet improves the data sharing capability and overall knowledge base of the company’s employees (Difference between Intranet and Extranet). Extranet, is an internal network that can be accessed externally. The extranet is the extension of the company’s intranet where People from outside the company can have a limited access to the company’s internal network for business related purposes. This access is usually granted to the organization’s partners, vendors and potential customers etc (Difference between Intranet and Extranet). Security-wise, Intranets are a lot more secure due to the limited interface with the Internet. Extranets are made less secure not only by the use of the Internet as a medium but also by the fact that the administrators of the Intranet have no control over the networks that connect to the Extranet. When sensitive information is being transmitted on the Intranet, all parties need to take...
