Human resources- detects and hires people, grips such matters as sick and tired leave, retirement life benefits, evaluation, reimbursement, and professional development.
Research- conducts product research and development, displays and troubleshoots services.
Discuss the assignments of the three varieties of management in a corporation.
Top level- worried about long-range planning and forecasting.
Middle-level- handles control, planning, decision making, and applying long-term goals.
Supervisors- control operational matters, screen day- to -day incidents, and supervise works.
What are the four most typical computer-based information systems?
Transaction processing system(TPS)
Management information system(SIM)
Decision support systems(DSS)
Executive support systems(ESS)
Describe different records and their assignments in managerial decision making.
Transaction control system(TPS)- record day-to-day transactions. For instance in accounting, which manages in six activities: sales order processing, accounts receivable, inventory and purchasing, accounts payable, payroll, and standard ledger.
Management information system(SIM)-produce predetermined periodic, exception, and demand reviews. Management information system use repository management systems to combine the databases of different departments.
Decision support systems(DSS)-enable professionals to get answers for unanticipated questions. Groups formed to handle large problems use group decision support systems(GDDS). A DSS consist of user, system software, data-internal and external, and decision models. Three types of decision models are proper, tactcal, and functional.
Executive support systems(ESS)-assist top-level executives. An professional support system is comparable to MIS or DSS but easier to use. ESSs are design designed for top-level decision producers.
What is the difference between an office automation system and an understanding work system?
Office automation systems(OAS) support data personnel who are involved with circulation and communication of information. Project managers and videoconferencing systems are OAS.
Knowledge work systems(KWS) support knowledege individuals, who creates information. Many engineers use computer aided design/ computer aided manufacturing(CAD/CAM) systems.
CHAPTER 12 : DATABASES
Describe the five reasonable data communities or categories.
Character-the most elementary logical data factor. It is a single letter, amount or special
character such as a punctuation draw or mark like $.
Field-field or group of related figure. A data field symbolizes an attribute
(explanation/characteristic) of some entity (person, place, thing or thing).
Record-collection of related areas. A record signifies a collection of attributes that
describe an entity.
Table-collection of related files.
Database-an integrated collection of logically related furniture.
What is the difference between batch processing and real-time processing?
Batch processing-data is accumulated over a time frame and the processing happens later
all at onetime.
Real-time processing-happens immediately when the purchase occurs.
Identify and determine the five part of DBMS programs.
DBMS engine-a bridge between the rational view of the info and the physical view of the info. When users request data(logical perspective), DBMS engine unit handles the details of actually locating data(physical point of view).
Data explanation subsystem-the logical structure of data-base by by using a data dictionary or
schema. This dictionary has a explanation of the framework of data in data source.
Data manipulation subsystem-provides tools for retaining and analyzing data. Maintaining data known as data maintenance includes adding new data, deleting data and editing and enhancing existing data. Analysis tools support looking at all or chosen elements of data,
querying repository and generating studies.
Application era subsystem-provides tool to make data entry forms and
specialized programming languages that user interface or work with common and trusted programming languages such as C or Visual Basic.
Data administration subsystem manages the database; data source administrators (DBAs) are computer pros who help identify processing rights.
What will be the five types of directories? Why does more than one kind of database exist?
-Individual
-Company
-Distributed
-Commercial
Databases designed for basic and specific business purposes include business internet directories, demographic data, business statistical information, wording databases, and Web databases.
What are some of the huge benefits and constraints of databases? Why is security a concern?
Two important security concers are unlawful use of data and unauthorized access. Most organizations use firewalls to safeguard their internal sites. Some benefits are in business such as financial and marketing. Restriction is designed for security of the organizations.
