Database languages are used to define, manipulate, and control access to data in a database management system. There are four main types of database languages: Data Definition Language (DDL) defines the database structure; Data Manipulation Language (DML) reads, inserts, updates, and deletes data; Data Control Language (DCL) controls user access privileges; and Transaction Control Language (TCL) manages transactions and rolling back or committing changes to the database.
Database Languages.pptx
Database languages allow developers to define, access, and manipulate data stored in databases. There are four main categories of database languages: data definition languages (DDL) are used to define database structure; data manipulation languages (DML) are used to insert, update, and retrieve data; data control languages (DCL) control user access and privileges; and transaction control languages (TCL) group statements into logical transactions and allow committing or rolling back changes. Common statements include CREATE, SELECT, INSERT, UPDATE, DELETE, COMMIT, and ROLLBACK.

It also introduces SQL as the standard language for interacting with relational database management systems and describes its core commands.
dbms advantages
A database management system (DBMS) is software that allows users to define, create, modify and control a database. A DBMS provides data definition and data manipulation languages to define schemas and query or update data. It also handles transaction management, concurrency control, recovery, security and storage of data. A database uses models to represent entities, attributes and relationships, and can change over time as information is added or removed while maintaining data integrity. Common database models include network, hierarchical, relational and object-oriented models.

Sql commands
SQL commands are instructions used to communicate with a database and perform tasks like creating tables, adding or modifying data, and setting user permissions. SQL commands are grouped into four categories: Data Definition Language for creating and modifying database structures; Data Manipulation Language for storing, retrieving, modifying, and deleting data; Transaction Control Language for managing data changes; and Data Control Language for providing security to database objects.
Database management system
DBMS is software that allows users to define, create, and manage a database. It provides users with data definition languages to define the database structure, data manipulation languages to interact with data, and a data dictionary to describe the metadata. Key functions of DBMS include storing, retrieving, and updating data; granting and revoking user privileges; recovering from crashes; and enforcing data integrity rules.
Sql
SQL was created in the 1970s by IBM as part of the System R project to store, manipulate, and retrieve data from relational databases.

Advanced control scheme of doubly fed induction generator for wind turbine us...
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
Rainfall intensity duration frequency curve statistical analysis and modeling...
Using data from 41 years in Patna’ India’ the study’s goal is to analyze the trends of how often it rains on a weekly, seasonal, and annual basis (1981−2020). First, utilizing the intensity-duration-frequency (IDF) curve and the relationship by statistically analyzing rainfall’ the historical rainfall data set for Patna’ India’ during a 41 year period (1981−2020), was evaluated for its quality. Changes in the hydrologic cycle as a result of increased greenhouse gas emissions are expected to induce variations in the intensity, length, and frequency of precipitation events. One strategy to lessen vulnerability is to quantify probable changes and adapt to them. Techniques such as log-normal, normal, and Gumbel are used (EV-I). Distributions were created with durations of 1, 2, 3, 6, and 24 h and return times of 2, 5, 10, 25, and 100 years. There were also mathematical correlations discovered between rainfall and recurrence interval.
Findings: Based on findings, the Gumbel approach produced the highest intensity values, whereas the other approaches produced values that were close to each other. The data indicates that 461.9 mm of rain fell during the monsoon season’s 301st week. However, it was found that the 29th week had the greatest average rainfall, 92.6 mm. With 952.6 mm on average, the monsoon season saw the highest rainfall. Calculations revealed that the yearly rainfall averaged 1171.1 mm. Using Weibull’s method, the study was subsequently expanded to examine rainfall distribution at different recurrence intervals of 2, 5, 10, and 25 years. Rainfall and recurrence interval mathematical correlations were also developed. Further regression analysis revealed that short wave irrigation, wind direction, wind speed, pressure, relative humidity, and temperature all had a substantial influence on rainfall.
Originality and value: The results of the rainfall IDF curves can provide useful information to policymakers in making appropriate decisions in managing and minimizing floods in the study area.

Medical image analysis has witnessed significant advancements with deep learning techniques. In the domain of brain tumor segmentation, the ability to
precisely delineate tumor boundaries from magnetic resonance imaging (MRI)
scans holds profound implications for diagnosis. This study presents an ensemble convolutional neural network (CNN) with transfer learning, integrating
the state-of-the-art Deeplabv3+ architecture with the ResNet18 backbone. The
model is rigorously trained and evaluated, exhibiting remarkable performance
metrics, including an impressive global accuracy of 99.286%, a high-class accuracy of 82.191%, a mean intersection over union (IoU) of 79.900%, a weighted
IoU of 98.620%, and a Boundary F1 (BF) score of 83.303%. Notably, a detailed comparative analysis with existing methods showcases the superiority of
our proposed model. These findings underscore the model’s competence in precise brain tumor localization, underscoring its potential to revolutionize medical
image analysis and enhance healthcare outcomes. This research paves the way
for future exploration and optimization of advanced CNN models in medical
imaging, emphasizing addressing false positives and resource efficiency.

This research paper introduces an innovative modulation technique for controlling a 3-level flying capacitor multilevel inverter (FCMLI), aiming to streamline the modulation process in contrast to conventional methods. The proposed
simplified modulation technique paves the way for more straightforward and
efficient control of multilevel inverters, enabling their widespread adoption and
integration into modern power electronic systems. Through the amalgamation of
sinusoidal pulse width modulation (SPWM) with a high-frequency square wave
pulse, this controlling technique attains energy equilibrium across the coupling
capacitor. The modulation scheme incorporates a simplified switching pattern
and a decreased count of voltage references, thereby simplifying the control
algorithm.

- 1. DBMS Basic Concepts BY: Ashish Kumar Singh 1
- 2. Database Languages 2 Database languages are used to create and maintain database on computer. • Data Definition Language(DDL): It is a language that allows user to define data and their relationship to other types of data. – CREATE – ALTER – DROP – TRUNCATE – RENAME • Data Manipulation Language(DML):It provides a set of operations to support the basic data manipulation operations on the data held in databases. It allows user to insert, update, delete and retrieve data from the database. – DELETE – INSERT – SELECT – UPDATE
- 3. Database Languages 3 • Data Control Language(DCL): DCL statements control access to data and the database – GRANT – REVOKE – COMMENT • Transaction Control Language(TCL): TCL statements manage the change made by DML statements, and group DML statements into transactions – COMMIT – ROLLBACK – SAVEPOINT – SET TRANSACTION
