Describe the external level of the ansi sparc?
The external level of the ANSI/SPARC architecture represents how users view the data stored in the database. It defines the logical view of the data for each user, which includes specifying the data format, structure, and access permissions that users interact with. This level shields users from the complexities of the internal and conceptual levels of the architecture.
Which format means users can view but not change data in a workbook?
Protected mode.
What is the difference between a logical view and a physical view of data?
The logical view presents data as they would be perceived by end users or business specialists, whereas the physical view shows how data are actually organized and structured on physical storage media.
What type of form enables a user to simultaneously view both simple form and database views of the data?
A "split form" in applications like Microsoft Access allows users to simultaneously view both a simple form and a database view of the data. This type of form displays a form view for data entry and a datasheet view for a tabular representation of the same data, enabling users to easily compare and edit information. This dual view enhances usability and data management efficiency.
Which of the following formats means that users can view but not change data in a workbook?
read only
What is data segregation?
Data segregation is certain data that has been restricted to certain users for view. Data can be filtered so that only the resources that are available to the individual will be seen.
What is the tool that enables users to view the same data in different ways using multiple dimensions?
The tool that enables users to view data in different ways using multiple dimensions is called a pivot table. Pivot tables allow users to reorganize and summarize data in a spreadsheet or database based on different criteria, such as rows, columns, and filters, making it easier to analyze and draw insights from the data.
A what is a temporary view of the data that is removed when you close the data?
A temporary view of data is often referred to as a "temporary table" or "temporary view" in databases. It allows users to create a view of data that exists only for the duration of a session or transaction. Once the session is closed or the transaction is completed, the temporary view is automatically removed, ensuring that it does not persist in the database. This feature is useful for managing data without affecting the underlying database schema.
What is different about creating a table in Design view instead of the Datasheet view?
Creating a table in Design view allows users to define the structure of the table, including field names, data types, and properties, offering greater control and precision. In contrast, Datasheet view presents a more spreadsheet-like interface where users can input data directly without specifying the underlying structure first. Design view is ideal for establishing the framework of a database, while Datasheet view is suited for data entry and quick edits.
How many windows in spss?
SPSS (Statistical Package for the Social Sciences) typically features three main windows: the Data View, where users can enter and view data in a spreadsheet format; the Variable View, which displays metadata about the variables in the dataset; and the Output Viewer, where results of analyses are presented. These windows allow users to efficiently manage data, define variable properties, and interpret output results.
What are the 2 views of table in access?
In Microsoft Access, tables can be viewed in two primary ways: Datasheet View and Design View. Datasheet View displays the data in a spreadsheet-like format, allowing users to easily view, enter, and edit records. Design View, on the other hand, provides a structure-oriented format where users can define or modify the table's fields, data types, and other properties. These views cater to different tasks, making data management more efficient.
What is Mapping bet internal conceptual and external views?
Mapping between internal conceptual and external views involves creating a bridge between how data is structured within a system (internal conceptual view) and how it is presented or interacted with by users or external systems (external view). The internal conceptual view represents the organization’s data model, including entities, relationships, and attributes, while the external view focuses on user interfaces and experiences. This mapping ensures that the underlying data is effectively aligned with user needs and applications, facilitating data accessibility and usability. Such alignment is crucial for effective data management and system design.
