All of the adhering to are benefits of database-stored information except: enhanced performance Increased adaptability Increased information integrity enhanced information redundancy
Why do relational databases use main keys and also foreign keys? all of these. To develop physical relationships. To develop logical relationships. To develop a database.

You are watching: What is the physical view of information


What type of website is best to construct for a general informational website through static information? revolution website Data-driven website every one of these Relational website
Which the the following is a valid kind of truth constraint? vital constraint Relational-critical truth constraint Business-critical integrity constraint business integrity constraint
What form of verity constraint go not permit someone to create an order because that a nonexistent customer? Information-critical truth constraint none of this Business-critical verity constraintRelational truth constraint
Which of the complying with measures how easily a device performs a certain process or transaction? PerformanceScalability Redundancy info integrity
What is an integration? bring away information entered into a given system and also sends it to the database.Allows different systems to communicate directly v each other. Takes information gone into into a provided system and also sends it to the DBMS. Bring away information gotten in into a provided system and sends the to other processes.
What is the physical watch of information? deals with the logical warehouse of info on a storage maker such together a tough disk.Deals with the physical warehouse of details on a storage an equipment such as a hard disk. Focuses on exactly how users logically access information to meet their particular business needs. Concentrates on just how users physically access information to meet their certain business needs.
What refers to just how well a system deserve to adapt to raised demands? Performance info integrity RedundancyScalability
What is a forward integration? takes information gone into into a offered system and also sends it come the DBMS. Takes information gotten in into a offered system and sends it immediately to every downstream systems and also processes. Bring away information entered into a offered system and sends it to the application-generation component. Bring away information entered into a given system and sends it immediately to every upstream systems and processes.
Takes information gone into into a offered system and sends it immediately to every downstream systems and processes.
In the relational database model, what is a person, place, thing, transaction, or event around which details is stored? AttributeLogical check out Entity physical view
Which the the adhering to is not an benefit of building a data-driven website? Minimizes human error.Minimizes or reduce efficiency. Cut production and also update costs.Improves or maximizes stability.
What is a international key? A ar (or group of fields) that uniquely identify a given entity in a table. A ar (or team of fields) that uniquely identifies a given attribute in a table. Qualities or properties of an entity. A primary an essential of one table that appears as an attribute in an additional table and acts to administer a logical relationship between the two tables.
A primary key of one table that appears as one attribute in one more table and also acts to administer a logical relationship in between the two tables.
What space the rule that aid ensure the quality of information? details integrity Business-critical verity constraintsIntegrity constraints Relational truth constraints
What type of website is ideal to build for a continually an altering information, consisting of press releases, new product information, and updated pricing? all of these static websiteData-driven website Relational website
Which that the complying with is incorrect in recommendation to a database? individuals can accessibility different see of information. Information is accessed by logical structure. Details is accessed by physics structure. Can be relational or network.
What is information redundancy? save the same information in multiple places. Storing duplicate details in many places. Every one of these. Duplication that information.
What is a backward integration? take away information gotten in into a provided system and also sends it come the DBMS.Takes information entered into a provided system and also sends it automatically to every upstream systems and processes. Take away information gotten in into a provided system and sends it automatically to all downstream systems and also processes. Bring away information gotten in into a given system and also sends it to the application-generation component.
Takes information gone into into a provided system and sends it automatically to every upstream systems and also processes.
What is the primary difficulty with redundancy information? the is challenging to identify which values room the most accurate. The is frequently inconsistent.All that these.It is daunting to determine which values room the most current.
What is a main key? A primary key of one table that shows up as one attribute in one more table and acts to provide a logical relationship in between the two tables.A field (or group of fields) the uniquely identifies a provided attribute in a table.A ar (or team of fields) that uniquely identify a given record in a table.Characteristics or properties of an entity.
Which the the complying with is true in regard to eliminating redundant information? Uses extr hard disc space. Renders performing information updates harder improves information quality. All of these.
