All of the following are benefits of database-stored information except: Increased performance Increased versatility Increased indevelopment integrity Increased indevelopment redundancy
Why do relational databases usage main keys and international keys? All of these. To develop physical relationships. To develop logical relationships. To produce a database.

You are watching: What is the primary problem with redundant information


What kind of webwebsite is finest to construct for a basic informational website through static information? Static webwebsite Data-propelled webwebsite All of these Relational website
Which of the complying with is a valid kind of integrity constraint? Critical constraint Relational-crucial integrity constraint Business-critical integrity constraint Business integrity constraint
What form of integrity constraint does not permit someone to create an order for a missing customer? Information-important integrity constraint None of these Business-instrumental integrity constraintRelational integrity constraint
Which of the following measures exactly how quickly a system percreates a details process or transaction? PerformanceScalcapacity Redundancy Indevelopment integrity
What is an integration? Takes information gone into into a given system and also sends it to the database.Allows separate systems to communicate straight via each various other. Takes information gotten in right into a offered system and also sends it to the DBMS. Takes indevelopment gone into into a provided system and sends it to various other procedures.
What is the physical watch of information? Deals via the logical storage of information on a storage tool such as a tough disk.Deals through the physical storage of information on a storage gadget such as a tough disk. Focsupplies on how individuals logically accessibility information to meet their particular business demands. Focprovides on how users physically access information to accomplish their certain service needs.
What describes just how well a system can adapt to increased demands? Performance Indevelopment integrity RedundancyScalability
What is a forward integration? Takes indevelopment entered into a provided device and sends out it to the DBMS. Takes indevelopment gotten in right into a provided system and sends it instantly to all downstream systems and also procedures. Takes information gotten in into a provided device and sends it to the application-generation component. Takes information entered right into a offered mechanism and also sends out it automatically to all upstream units and procedures.
Takes information gone into into a provided system and also sends out it automatically to all downstream units and also processes.
In the relational database model, what is a perchild, place, thing, transactivity, or event around which information is stored? AttributeLogical watch Entity Physical view
Which of the adhering to is not an benefit of building a data-propelled website? Minimizes huguy error.Minimizes or reduces efficiency. Cuts production and also update prices.Improves or maximizes stcapacity.
What is a international key? A field (or group of fields) that uniquely identifies a provided entity in a table. A field (or group of fields) that uniquely identifies a offered attribute in a table. Characteristics or properties of an entity. A primary vital of one table that appears as an attribute in one more table and also acts to provide a logical partnership between the two tables.
A major crucial of one table that appears as an attribute in one more table and also acts to carry out a logical connection in between the 2 tables.
What are the rules that aid encertain the high quality of information? Indevelopment integrity Business-crucial integrity constraintsIntegrity constraints Relational integrity constraints
What form of webwebsite is finest to develop for a continually changing information, including press releases, brand-new product information, and also updated pricing? All of these Static websiteData-moved website Relational website
Which of the complying with is incorrect in reference to a database? Users have the right to accessibility different views of information. Information is accessed by logical structure. Information is accessed by physical framework. Can be relational or netoccupational.
What is indevelopment redundancy? Storing the very same information in multiple locations. Storing duplicate indevelopment in multiple locations. All of these. Duplication of indevelopment.
What is a backward integration? Takes information gotten in right into a provided system and sends out it to the DBMS.Takes information gone into into a given system and also sends out it automatically to all upstream devices and processes. Takes indevelopment entered into a provided device and also sends out it automatically to all downstream units and procedures. Takes information gotten in right into a given mechanism and also sends out it to the application-generation component.
Takes indevelopment gotten in right into a given mechanism and also sends it automatically to all upstream units and also procedures.
What is the main difficulty through redundant information? It is tough to identify which values are the the majority of exact. It is regularly incontinual.All of these.It is difficult to identify which worths are the many existing.
What is a primary key? A main crucial of one table that appears as an attribute in another table and also acts to carry out a logical connection in between the two tables.A area (or team of fields) that uniquely identifies a offered attribute in a table.A area (or group of fields) that uniquely identifies a offered document in a table.Characteristics or properties of an entity.
Which of the complying with is true in regard to eliminating redundant information? Uses additional difficult disk room. Makes performing indevelopment updates harder Improves indevelopment top quality. All of these.
