Objasniti na primjeru marieDB DD?
Data Dictionary (DD) u MariaDB-u je sustav koji pohranjuje meta podatke o bazama podataka, tablicama, kolonama, indeksima, ključevima, ograničenjima i drugim objektima baze podataka. Meta podaci su informacije koje opisuju strukturu i karakteristike podataka u bazi. Data Dictionary omogućuje lakše upravljanje bazom podataka, transparentnost i dosljednost u radu s podacima.
Kao primjer upotrebe možemo iskoristiti SELECT upit:
SELECT table_name

Computer Security refers to the protection of computer systems and networks from theft, damage, unauthorized access, misuse, or disruption of services. It ensures confidentiality, integrity, and availability of data. The need for security arises because of increasing cyber threats, sensitive data storage (e.g., financial records, medical data), online transactions, and dependence on cloud services. Without security, systems are vulnerable to data breaches, identity theft, and financial losses. Security
...B.Tech. Unit-VI-Water Chemistry
Hardness in water is due to Ca²⁺ and Mg²⁺ ions.
It is determined by complexometric titration using EDTA (Ethylenediaminetetraacetic acid).
EDTA forms a stable, soluble complex with Ca²⁺ and Mg²⁺ ions.
Indicator used: Eriochrome Black-T (EBT).
At pH ≈ 10 (buffered with NH₄OH–NH₄Cl buffer), EBT forms a wine-red complex with Ca²⁺/Mg²⁺.
During titration, EDTA replaces EBT,
Q.1 (a) Explain the principle of Maximum Social Advantage.
The Principle of Maximum Social Advantage is one of the fundamental principles of public finance, introduced by Prof. Hugh Dalton. It provides guidance to governments on how to use taxation and public expenditure in such a way that social welfare is maximized.
Concept
Public finance involves two main activities:
a. Taxation which imposes a burden on the people.
b. Public Expenditure which provides benefits to society.
The government must...
Q 10Explain about demineralization of brakish water by Electrodialysis.
Here’s a detailed explanation of Demineralization of Brackish Water by Electrodialysis from your PDF and standard water chemistry concepts:
🌊 Brackish Water
Brackish water contains dissolved salts (less than seawater, more than freshwater).
It tastes salty and is unsuitable for drinking or industrial use.
To make it potable, salts must be removed (desalination)

Slobodni režim rada nije mnogo praktičan zato što se u tom slučaju na ekranu umesto
jednog signala dobija veći broj sinusoidalnih delova tog signala, naslaganih jedan preko
drugog, što se može jasno uočiti sa Slike 11.8. Zbog toga se slobodni režim rada vremenske baze vrlo retko primenjuje, a najčešće su u primeni sinhronizovani ili okidni režim rada vremenske baze.
Kod sinhronizovanog režima rada početak nove periode signala vremenske baze se uvek
Hardness of water is due to the presence of Ca²⁺ and Mg²⁺ ions.
In the EDTA method, a solution of Ethylenediamine Tetraacetic Acid (EDTA) is used as a titrant.
EDTA forms stable, soluble complexes with Ca²⁺ and Mg²⁺ ions.
At the end point, all Ca²⁺ and Mg²⁺ ions are complexed, and the indicator shows a color change.
