1. Explain how a group support system (GSS) works
Group support system is a collection of computer based information system, which is utilized to aid organizational communication and decision-making activities, where groups are involved. Group Support System have several applications in organizations, and how the specific GSS systems work may vary, in general, group support systems works by facilitating and managing communication between different parties, these systems includes Computer Supported Cooperative Work, groupware and collaborative systems, this offers features such as web conferencing, scheduling and activity allocation. Some systems have decision support capabilities where they work by collecting data from diverse sources, such as the internet and past records of the organization, which are stored in databases, the system then analyses the data collected and makes the best possible decision, or propose strategies.
The benefits of the GSS include automated record keeping and archiving, parallel and synchronized communication, reduces meeting time, promotes interactivity and enables more data to be send within a given time period.
Executive information system is a system intentioned to be used by senior management of organization to achieve strategic objectives by promoting flow of information and aiding in decision making.
Function of the data administration group
The function of the data administration group is to ensure that the performance of the organizations database is optimized and that the data contained in the database obeys the ACID properties (atomicity, consistency, isolation, durability) and that the data in the organizations database is integral.
The key functions of the data administration group are diverse and depend on the organization. These functions include recognizing and categorizing the data requirements of the users, the group then designs a database system to match the needs. The data administration group has also the function of testing and implementing the database system and maintaining the system to ensure that it has optimal performance.
The data administration group has also the function of ensuring that the database is secure, this includes implementing security measures such as installing of anti spy ware and antivirus and avoiding potential sources that can compromise the security of the system such as hackers and crackers. In addition, the group has also the function of implementing recovery strategies when the databases crushes or is compromised, this includes having regular backups and secure offshore storage of critical data. The group also regulates the users of the database system.
3. Modern Enterprise Resource Planning (ERP) systems differ from earlier systems in two ways. Describe these new approaches?
Enterprise Resource Planning is defined as the amalgamation of business management and advances in technology. The earlier systems of ERP were intentioned to automate and integrate the organizations business processes. However changes in technology have called for changes in ERP approaches in order to meet the organizations changing strategic needs. The resultant difference between earlier ERP and the modern ERP approaches include WEB centric application.
The modern Enterprise resource Planning approach have been designed to integrate and utilize the web as an important component in the business operations, this has been progressed by advances in electronic business and online trading, the approach contrasts with the earlier ERP which had limited web capabilities, therefore they did not fully utilize the internet but rather used it as a support feature, The approach of the modern ERP is totally web friendly and the web constitute the backbone of the several communicating modules.
According to Leon (2007), the other difference on approach is on wide intensive and extensive coverage. The earlier systems utilized either selected intensive coverage or wide extensive coverage exclusively, which had limitations in terms of achieving a balance of the relating Macro and Micro elements, the modern Enterprise Resource Planning approach in contrast achieves a balance of the Micro and Macro elements. This overcomes the challenges experienced with the earlier Enterprise Resource Planning.
