Study Notes
Chapter 6: Understanding DSS Architecture, Networking, and Security Issues
- Information technology (IT) architectures and computing infrastructures are rapidly evolving in corporations. Some companies build IT infrastructure opportunistically, but a better approach involves careful design for support costs, user productivity, and avoiding crashes or performance problems. A network is crucial for enterprise-wide and communication-driven decision support systems (DSS).
IT Architecture and Infrastructure
-
DSS architectures involve user interfaces, databases, models/analytical tools, and the architecture/network.
-
User interfaces are built with tools like DSS generators, query tools, and front-end development packages
-
Databases are important and can be centralized or distributed.
-
Model management software is often part of DSS, especially model-driven DSS. Model management software can be centralized or distributed.
-
Network architectures and security considerations are interlinked. Essential for successful DSS design, development, and implementation
DSS Architecture and Networking
- Network design is part of DSS architecture.
- Security is directly affected by architectural and network choices.
Client/Server Architecture
-
Common DSS architecture, involving client processes requesting service from server processes over a network.
-
Clients provide the user interface, and servers manage resources like databases or analytical processors. Client and server hardware requirements differ substantially.
-
Scalability (horizontally or vertically) is important in client/server systems.
Networking issues
-
Enterprise-wide DSS have interconnected servers, databases, and workstations. The existing corporate network may form a part of the DSS architecture, but it's essential to assess how it impacts future needs.
-
Web-based DSS often use the TCP/IP protocol for global communication.
-
Understanding the concept of networking, TCP/IP, and related terminology is important for DSS analysts and managers.
-
Networks allow shared resources (data, information, storage)
-
Networks utilize protocols (rules) for communication, like TCP/IP.
-
Local Area Networks (LANs) connect devices within a specific area.
-
Wide Area Networks (WANs) connect multiple LANs, sometimes including the global Internet.
Improving Security for DSS
-
Security is a major concern (growing reports of computer crime).
-
Security evaluation, implementation, monitoring, and updates provide proactive security measures.
-
Security includes passwords, user education, file permissions, firewalls, and secure servers
-
Firewalls, acting as gateways, control network access and restrict unauthorized traffic.
-
Understanding how hackers access and compromise systems is critical for security improvement.
-
The network of networks, or the Internet, provides wide accessibility but introduces security concerns about the level of security needed and what risks are involved.
-
System administrators should be familiar with protocols for managing security and vulnerabilities.
