Sampling in information systems refers to the process of selecting a subset of data or transactions from a larger dataset for analysis or testing. It allows organizations to efficiently analyze information without having to process entire datasets, which can be time-consuming and resource-intensive. Sampling helps in making inferences about the larger dataset based on the characteristics of the sampled data.

Difference between information system and file system?
Information system consists of collection of information which are stored in memory. This include library segments, data segments, system segments etc. Module of operating system dealing with management of information is called file system. File system is intended to provide convenient management of information. So the programmer is freed from problems related to the allocation of space for for his information as well as other problems such as storage format and I/O addressing.
Which table store information about database or about the system?
Information about databases and systems is typically stored in system tables called data dictionaries or system catalogs. These tables contain metadata about the structure and organization of the database, as well as information about users, privileges, and other system-related details. Database management systems like Oracle, MySQL, and SQL Server provide built-in tables for querying this information.
Technological and behavioral aspects of information system?
Technological aspects of an information system refer to the hardware, software, and network infrastructure that enable data processing and storage. Behavioral aspects, on the other hand, pertain to how individuals interact with the system, including user behavior, adoption challenges, and the impact on workflows and decision-making processes. Balancing both technological capabilities and user needs is crucial for the successful implementation and utilization of an information system.
5 componets of an information system?
Hardware: Physical components such as computers, servers, and networking devices. Software: Programs and applications that provide functionality for users. Data: Information that is stored, processed, and utilized by the system. Procedures: Guidelines and instructions for users on how to interact with the system. People: Individuals who manage, operate, and use the information system.
How the limits of a particular electronic information system and the security level of users may affect the information that is accessible on that system?
The limits of an electronic information system, such as storage capacity or processing speed, can affect the amount and type of information that can be accessed on the system. If the system has limited storage, for example, it may only be able to store a limited amount of information, resulting in some data being inaccessible. Additionally, the security level of users can impact the information accessible on the system, as users with lower security permissions may be restricted from accessing certain sensitive or confidential information.
