Database Systems 2025/2026 Exam
Questions and Answers | A+ Score
Assured
database management system (DBMS) - 🧠 ANSWER ✔✔Software that allows the
computer to create a database; add, change, and delete data in the database; sort the
data; retrieve the data; and create forms and reports using the data in the database.
Serves as an intermediary between the user and the database.
relational database (RDBMS) - 🧠 ANSWER ✔✔The basic data structure is a table
with the rows representing entities (e.g., a customer) and the columns representing
the various attributes of the entity (row, entity, record, column, attribute, field).
semistructured data - 🧠 ANSWER ✔✔Data that have been processed to some
extent; most data is this way.
, NoSQL - 🧠 ANSWER ✔✔A new generation of database management systems that
is not based on the traditional relational database model.
big data - 🧠 ANSWER ✔✔It refers to data sets are beyond the ability of commonly
used software tools to capture, store, manage and process within acceptable time
limits.
Hadoop - 🧠 ANSWER ✔✔Open source suite of software apps for analyzing
unstructured data
in-memory database - 🧠 ANSWER ✔✔In-memory databases store most of their
data in primary memory (RAM) rather than in slower secondary storage (hard
disks). Supports the need for faster database processing.
parallel computing - 🧠 ANSWER ✔✔The simultaneous execution of the same task
on multiple processors to obtain results faster.
multicore processor - 🧠 ANSWER ✔✔Integrated circuit to which two or more
processors have been attached for enhanced performance, reduced power
consumption and more efficient simultaneous processing of multiple tasks.
integrated circuit - 🧠 ANSWER ✔✔A group of tiny transistors and electric wires
built on a silicon wafer, or chip.
