MT Abstract Kompetensi PenjelasanData Resource Mnagement Mengertidanmemahami Data Resource MAnagement SistemManajemenMutuKonstruksi Data Resource Management A managerial activity Applies information systems technology to managing data resources to meet needs of business stakeholders. Foundation Data Concepts Levels of data Character Single alphabetical, numeric, or other symbol Field Groupings of characters Represents an attribute of some entity Records Related fields of data Collection of attributes that describe an entity Fixed-length or variable-length Files (table) A group of related records Classified by Primary use Type of data permanence Database Integrated collection of logically related data elements Consolidates records into a common pool of data elements Data is independent of the application program using them and type of storage device ‘13 2 SistemManajemenMutuKonstruksi Budi Santosa, ST. MT PusatBahan Ajar dan eLearning http://www.mercubuana.ac.id Logical Data Elements Types of Databases Operational Supports business processes and operations Also called subject-area databases, transaction databases, and production databases Distributed Replicated and distributed copies or parts of databases on network servers at a variety of sites. Done to improve database performance and security External Available for a fee from commercial sources or with or without charge on the Internet or World Wide Web Hypermedia Hyperlinked pages of multimedia Data Warehouses and Data Mining Data warehouse Stores data extracted from operational, external, or other databases of an organization Central source of “structured” data ‘13 3 SistemManajemenMutuKonstruksi Budi Santosa, ST. MT PusatBahan Ajar dan eLearning http://www.mercubuana.ac.id May be subdivided into data marts Data mining A major use of data warehouse databases Data is analyzed to reveal hidden correlations, patterns, and trends Database Management Approach Consolidates data records and objects into databases that can be accessed by many different application programs Database Management System Software interface between users and databases Controls creation, maintenance, and use of the database Database Interrogation Query Supports ad hoc requests Tells the software how you want to organize the data SQL queries Graphical (GUI) & natural queries Report Generator Turns results of query into a useable report Database Maintenance Updating and correcting data Application Development ‘13 4 SistemManajemenMutuKonstruksi Budi Santosa, ST. MT PusatBahan Ajar dan eLearning http://www.mercubuana.ac.id Data manipulation language Data entry screens, forms, reports, or web pages Implementing Data Resource Management Database Administration Develop and maintain the data dictionary Design and monitor performance of databases Enforce database use and security standards Data Planning Corporate planning and analysis function Developing the overall data architecture Data Administration Standardize collection, storage, and dissemination of data to end users Focused on supporting business processes and strategic business objectives May include developing policy and setting standards Challenges Technologically complex Vast amounts of data Vulnerability to fraud, errors, and failures Technical Foundations of Database Management Database Structures Hierarchical Treelike One-to-many relationship Used for structured, routine types of transaction processing Network More complex Many-to-many relationship More flexible but doesn’t support ad hoc requests well Relational ‘13 5 SistemManajemenMutuKonstruksi Budi Santosa, ST. MT PusatBahan Ajar dan eLearning http://www.mercubuana.ac.id Data elements stored in simple tables Can link data elements from various tables Very supportive of ad hoc requests but slower at processing large amounts of data than hierarchical or network models Multi-Dimensional A variation of the relational model Cubes of data and cubes within cubes Popular for online analytical processing (OLAP) applications Object-oriented Key technology of multimedia web-based applications Good for complex, high-volume applications ‘13 6 SistemManajemenMutuKonstruksi Budi Santosa, ST. MT PusatBahan Ajar dan eLearning http://www.mercubuana.ac.id Accessing Databases Key fields (primary key) A field unique to each record so it can be distinguished from all other records in a table Sequential access Data is stored and accessed in a sequence according to a key field Good for periodic processing of a large volume of data, but updating with new transactions can be troublesome Direct access Methods Key transformation Index Indexed sequential access Database Development Data dictionary Directory containing metadata (data about data) Structure Data elements Interrelationships Information regarding access and use Maintenance & security issues Data Planning & Database Design ‘13 7 SistemManajemenMutuKonstruksi Budi Santosa, ST.
