Submit
79. Šta od navedenog se odnosi na pojam podatka?

Explanation

The correct answer is "je reprezentacija činjenice ili ideje pogodna za komunikaciju, interpretaciju i obradu od strane ljudi i upravljačkih mašina". This answer accurately describes data as a representation of facts or ideas that can be communicated, interpreted, and processed by both humans and machines. It emphasizes the importance of data in facilitating communication and enabling meaningful analysis and decision-making. The other options either do not fully capture the essence of data or are not comprehensive enough in their descriptions.

Submit
80. Uslovi referencijalnog integriteta 

Explanation

The correct answer states that referential integrity conditions prevent records from referencing records that do not exist in the same or another table. This means that when a record in one table references a record in another table, the referenced record must exist in that table. This ensures that data integrity is maintained and avoids any inconsistencies or errors that may occur if a record references a non-existent record.

Submit
81. Šta od navedenog su karakteristike relacionih baza?

Explanation

The given answer states that the characteristic of relational databases is that data is organized in rows and columns, and this set of data is called a relation. It also states that all values in a relational database are scalar, meaning they are single values and not collections or arrays. This explanation correctly identifies the characteristics of relational databases.

Submit
82. Agregacija je

Explanation

The correct answer states that aggregation is an abstraction in which a collection of related objects is treated as a single object. This means that multiple objects are grouped together and treated as one entity. Aggregation allows for a higher level of abstraction and simplifies the representation and manipulation of complex systems.

83. Pravilo koje zabranjuje korisniku da izbriše zapis o kupcu za kojeg postoje nezavršene porudžbine, važi za koji uslov integriteta?

Explanation

The correct answer is "Primarni." The rule that prohibits a user from deleting a customer record for whom there are unfinished orders is a condition of primary integrity. This means that the customer record is essential and cannot be deleted as long as there are related unfinished orders. The primary key of the customer record is likely linked to the unfinished orders table, ensuring data consistency and preventing data loss.

Submit
84. Komponente komunikacije podataka (DC) DDBMS-a

Explanation

The correct answer is "softver koji omogućava komunikaciju među lokacijama". This answer is correct because it accurately describes the role of data communication components (DC) in a distributed database management system (DDBMS). These components enable communication between different locations or sites in a distributed system, allowing for the exchange of data and information.

Submit
85. Šema baze podataka

Explanation

The correct answer is "opisuje fizičku strukturu podataka." This is because the term "šema baze podataka" refers to the physical structure of data, which includes the organization and storage of data on a physical storage medium such as a hard drive. The other options, "definiše logičku strukturu podataka" (defines the logical structure of data) and "definiše i logičku i fizičku strukturu podataka" (defines both the logical and physical structure of data), do not accurately describe the concept of "šema baze podataka."

Submit
86. Šta NIJE oblik projektnog uslova

Explanation

The correct answer is "Određivanje ciljeva sistema i projekta kao celine." This is because the question states that "Šta NIJE oblik projektnog uslova" which translates to "What is NOT a form of project requirement." The other options listed - Direktno merljivi zahtevi (Direct measurable requirements) and Opšte projektne strategije (General project strategies) - can be forms of project requirements, but "Određivanje ciljeva sistema i projekta kao celine" (Determining the goals of the system and project as a whole) is not a form of project requirement.

Submit
87. Distribuirana obrada 

Explanation

The correct answer is "centralizovna baza kojoj se može pristupiti preko računarske mreže". This means that the database is centralized and can be accessed through a computer network.

Submit
88. Korisnicima obezbediti pomoć zavisnu od konteksta je

Explanation

The correct answer is "Opšta projektna strategija." This is because providing context-dependent assistance to users is a general project strategy that can be implemented in various ways. It is not a directly measurable requirement or a condition related to the work environment.

Submit
89. Šta NIJE izvor za uslove radnog okruženja?

Explanation

The given answer is correct because it directly addresses the question and provides an appropriate response. The question asks for something that is not a source for the working environment conditions, and the answer "Koji su zadaci na datom radnom mestu" (What are the tasks at the given workplace) is unrelated to the source of working environment conditions. Therefore, it is a valid explanation for the correct answer.

Submit
90. Komponente na sloju  transakcije odgovaraju za

Explanation

The components in the transaction layer are responsible for assembling and sending queries, processing errors and rule violations reported by the external access layer, receiving data from the external access interface layer, and executing business processes.

Submit
91. Očuvanje konzistentnosti korišćenjem transakcija

Explanation

The correct answer suggests that the preservation of consistency using transactions involves adhering to all integrity constraints. This means that all rules and requirements for maintaining data integrity must be followed during the execution of transactions.

Submit
92. Utvrđivanje uslova za projektovanje i izradu projekta služe za

Explanation

The correct answer is "za procenjivanje uspešnosti projekta i za procenu valjanosti kompromisa." This is because determining the conditions for designing and developing a project helps in evaluating the success of the project and assessing the validity of compromises made. It allows for an assessment of whether the project is meeting its goals and objectives and whether any compromises made are reasonable and effective.
