 The requirement is to use space efficiently in a user interface where the meaningful order of components is vertical. A columns layout is the most appropriate layout component for this requirement, as it allows you to arrange components into columns that stack vertically on smaller devices. A columns layout also provides options to control the width, alignment, and visibility of each column. The other options are not suitable for this requirement, as they either do not preserve the vertical order of components or do not use space efficiently. References:

• Columns Layout

A joining table can be used to hold instances of Student/Class relationships, so that it can be supported in Appian and remain in at least First Normal Form. A joining table is a table that contains only foreign keys that reference the primary keys of other tables. A joining table can be used to model a Many-to-Many relationship between two entities, such as Student and Class. For example, a joining table called Enrollment could have two columns: Student_ID and Class_ID, which reference the primary keys of the Student and Class tables respectively. Each row in the Enrollment table represents an instance of a student enrolled in a class. References: [Joining Tables], [Many-to-Many Relationships], [First Normal Form]

 According to Appian best practices, the preferred style and size for the images to display the profile picture of each employee inside an employee grid are style: “AVATAR” and size: “SMALL”. This is because the avatar style creates a circular image that is suitable for profile pictures, and the small size creates a 32x32 pixel image that fits well inside a grid cell. The standard style creates a rectangular image that may not look good for profile pictures, and the large size creates a 128x128 pixel image that may be too big for a grid cell. References: Image Component

The appian_log4j.properties file is used to configure the logging levels for Appian components, including authentication. You can modify this file to increase or decrease the verbosity of the log output for different categories. For example, to enable trace-level logging for SAML authentication, you can add this line to the file: log4j.logger.com.appiancorp.suite.authentication.saml=TRACE References: [Appian Logging Configuration], [SAML Troubleshooting]
