Data Administration - an overview | ScienceDirect Topics C) analysis D) implementation, The SDLC phase in which the detailed conceptual data model is created is the ________ phase. A) creating data. The need for consensus on data definitions is an example of which type of risk in the database environment? ________ are established between entities in a well-structured database so that the desired information can be retrieved. Should data be migrated, or just the database structures? All of the following are properties of metadata EXCEPT: processing logic. C) analysis D) database process. Standards for SA may include, The development of database applications differs from typical program development. C) relation. B) Application development They can be stored as a printed document, in an online format for easy access, or in both ways. Developing robust communication standards can simplify a DBAs job during the inevitable downtime that occurs due to system, application, or even hardware errors. C) Technical services A strict database naming convention, if not developed logically, can be antithetical to a useful and effective database environment. The type of object can always be determined by querying the DBMS system catalog or data dictionary. C) The desire to require programmers to write all file handling functionality. C) data descriptions being written into programming code. Explain how to identify the opposite and adjacent legs of a given acute angle. There is no practical reason to impose a limitation on the length of database table names. Which organizational function should set database standards? We use this information to address the inquiry and respond to the question. B) Predictable use of data Database development begins with the design of the database. C) Cross-functional C) 60 percent Database maintenance is typically the longest step of the database development process. A) what a user sees when he or she looks out the window. At a minimum, information will be required about the requester, when and why the objects should be migrated, and the appropriate authorization to approve the migration. For example, a good name for the table containing employee information in a human resources system would be HR_EMPLOYEE. Table names should be as descriptive as possible, within reason. > Operational support assures that applications are run according to schedule. Answer: C Structured query language ________ is a tool even non-programmers can use to access information from a database. processing. ISO management system standards (MSS) help organizations improve their performance by specifying repeatable steps that organizations consciously implement to achieve their goals and objectives, and to create an organizational culture that reflexively engages in a continuous cycle of self-evaluation, correction and improvement of operations and LO: 1: Explain at least 10 advantages of the database approach, compared to traditional file A) relationship. LO: 1: Define key terms. Given that, this sidebar offers short definitions of the database objects mentioned in this section. AACSB: Information Technology, Database management involves all of the following EXCEPT: C) 1970s. B) Systems Development Life Cycle. An additional set of DBA standards that cover database performance monitoring and tuning may be useful to document procedures for overcoming performance problems. One of the most popular RAD methods is: Which of the following will interfere with access to operational databases? Log data may include technical information about how a user or visitor connected to this site, such as browser type, type of computer/device, operating system, internet service provider and IP address. Answer: D C) Systems analysts What are some of your most useful database standards? processing. Applications built with a multitier architecture are meant to support departments. In practice, databases today may contain either data or information. C) Improved responsiveness B) Users D) entity. A) collecting data. An extranet uses Internet protocols to establish limited access to company data by the company's customers and suppliers. Often, updates are made to provide greater clarity or to comply with changes in regulatory requirements. Data processed in a way that increases a user's knowledge is: Data that describe the properties of other data are: All of the following are properties of metadata EXCEPT: One disadvantage of file processing systems is: file descriptors being stored in each application. C) reports. AACSB: Information Technology, A user view is: It is possible to make all the database object names the same by assigning each environment to a different instance or subsystem. While design of databases would be part of solution architecture, the implementation and maintenance of development and production database environments would be the work of the DBA. A person, place, object, event, or concept about which the organization wishes to maintain data is called a(n): A rule that CANNOT be violated by database users is called a: are established between entities in a well-structured database so that the desired information can be retrieved.
