Monkey B Virus Monkey B virus,  also known as  Herpes B virus,  is a viral infection that can be transmitted from macaque monkeys to humans. The virus is a member of the herpesviridae family, which includes herpes simplex viruses (HSV) in humans. While monkey B virus infections in macaques usually do not cause symptoms, in humans, they can lead to severe and potentially fatal diseases. Transmission:  Monkey B virus is primarily transmitted to humans through direct contact with the bodily fluids or tissues of infected macaque monkeys, especially through bites, scratches, or mucosal exposure. Laboratory workers and researchers who handle macaque monkeys are at higher risk of exposure. Symptoms:  In humans, the infection can cause a rare but serious condition called  B virus encephalitis.  Symptoms may include fever, headache, muscle aches, fatigue, and later neurological symptoms such as confusion, agitation, and paralysis. If left untreated, B virus enc...

अदिश तथा सदिश राशिया (Scalar and Vector quantities in Hindi) भौतिक राशि दो प्रकार के होते हैं: अदिश तथा सदिश आदिश राशिया कुछ राशि ऐसी होती हैं जिनका केवल परिणाम होता है उनकी कोई दिशा नहीं होती जैसे द्रव्यमान, दूरी, समय, चाल, आयतन, घनत्व, दाब, कार्य ,ऊर्जा, शक्ति ,आवेश, विद्युत धारा, ताप, विशिष्ट ऊष्मा  इत्यादि ऐसे राशियों को अदिश राशियां करते हैं। किसी भी अदिश राशि को केवल एक संख्या तथा एक मात्रक द्वारा पूरी तरह व्यक्त किया जा सकता है उदाहरण के लिए एक ट्रक का द्रव्यमान 200 किग्रा है मेरे घर से कालेज की दूरी 2 किलोमीटर है मेरे पास 2 घंटे समय है इन सभी वाक्यों में हमने राशि के संबंध में पूरी बात कह दिया अब इस राशियों का जोड़ना घटाना गुणा भाग  गणित की सहायता से किया जा सकता है। सदिश राशिया  कुछ राशियां ऐसी ही होती हैं जिनमें परिणाम के साथ-साथ की दिशा होती है जैसी स्थिति ,विस्थापन ,त्वरण बल संवेग, विद्युत क्षेत्र ,चुंबकीय बल क्षेत्र ,धारा, घनत्व इत्यादि  ऐसी राशियों को सदिश राशियां कहते हैं।  किसी भी सदिश राशि को पूरी तरह व्यक्त करने के लिए राशि के पर...

Database Language Types of Database Language  Data definition language (DDL), Data manipulation language (DML), Data control language (DCL), Transaction control language (TCL), Database Language A DBMS has appropriate languages and interfaces to express database queries and updates. Database languages can be used to read, store and update data in the database. Types of Database Language 1. Data Definition Language DDL stands for Data Definition Language. It is used to define the database structure or pattern. It is used to create schema, tables, indexes, constraints etc in the database. Using DDL statements, you can create the skeleton of the database. Data Definition Language is used to store the information of Meta data such as number of tables and schemas, their names, indexes, columns in each table, constraints, etc. Here are some tasks that come under DDL: Create: It is used to create objects in the database. Alter: It is used to change the structure of the database. Drop: ...

DBMS–Data Independence Data independence can be explained using three-schema architecture. Data independence refers to being able to modify the schema at one level of the database system, without changing the schema at a higher level. There are two types of data independence: 1. Logical Data Independence Logical data independence refers to the attribute of being able to change the conceptual schema without changing the external schema. Logical data independence is used to separate the external level from the conceptual view. If we make any changes in the conceptual view of the data, then the user view of the data will not be affected. There is logical data independence at the user interface level.  2. Physical Data Independence Physical data independence can be defined as the ability to change the internal schema without changing the conceptual schema. If we make any changes in the storage size of the database system server, then the conceptual structure of the database will not be...

SEBI introduces 'expected loss-based' rating scale The Security Exchange Board of India (SEBI) has introduced a new framework for the "expected loss-based rating scale". Main points of Expected loss-based Under this new framework, credit rating agencies are required to provide requisite loss-based ratings for projects and equipment that are linked to the infrastructure sector. The expected loss-based rating introduced by SEBI is divided into a scale of seven levels. This new scale will be used by credit rating agencies to rate projects or equipment related to the infrastructure sector. All the provisions in the latest circular will be applicable to credit rating agencies with 'immediate effect', except the provision relating to standardization of rating scales. The circular was issued in exercise of the powers under section 11(1) of the Securities and Exchange Board of India Act, 1992. Seven levels of damage The seven expected levels of loss on the new scale p...

Data model Schema and Instance The data which is stored in the database at a particular moment is called an instance of the database. The overall design of a database is called schema A database schema is the skeleton structure of the database. It represents the logical view of the entire database. A schema includes schema objects such as tables, foreign keys, primary keys, views, columns, data types, stored procedures, etc. A database schema can be represented using a visual diagram. This diagram shows the database objects and their relationship with each other. A database schema is designed by database designers so that the programmers whose software will interact with the database. The process of database creation is called data modeling. A schema diagram can display some aspects of a type of schema named record types, data types and constraints. Other aspects cannot be specified through a schema diagram. The given figures, for example, show neither the data type of each data item n...

Three schema Architecture DBMS Three schema Architecture Internal Level  Conceptual Level  External Level  Three schema Architecture  Three schema architecture is also called ANSI / SPARC architecture or three-level architecture. This framework is used to describe the structure of a specific database system. The three schema architecture is also used to separate user applications and physical databases. There are three levels in the three schema architecture. It breaks the database into three different categories. The three-schema architecture is as follows: In the above diagram: It shows the DBMS architecture. Mapping is used to convert request and response between different database levels of the architecture. Mapping is not good for small DBMS as it takes more time. External / conceptual mapping, it is necessary to convert the link from the external level to the conceptual schema. Conceptual / internal mapping converts DBMS requests from conceptual to internal lev...

DBMS Architecture DBMS Architecture (database management system architecture)  Types of DBMS Architecture 1-tier architecture 2-tier architecture 3-tier architecture DBMS Architecture DBMS design depends on its architecture. Basic client/server architecture is used to deal with the large number of PCs, web servers, database servers and other components that are associated with the network. Client/Server Architecture consists of multiple PCs and a workstation which are connected via a network. The DBMS architecture depends on how the users are connected to the database to receive their requests. Types of DBMS Architecture Database Architecture can be viewed as single tier or multi-tier. But logically, there are two types of Database Architecture such as: 2-tier architecture and 3-tier architecture. 1-Tier Architecture In this architecture, the database is directly available to the user. This means that the user can access the DBMS directly. The changes made here will be done directl...

DBMS vs file system Differentiate between DBMS and file system, difference table of Dbms vs File system, Dbms vs file system. DBMS DBMS is a collection of data. In DBMS, the user is not required to write the procedures. DBMS gives an abstract view of the data which hides the details. DBMS provides a crash recovery mechanism, i.e. protects the user from the failure of the DBMS system. DBMS provides a good protection mechanism. There are many types of sophisticated techniques to store and retrieve data in DBMS. The DBMS takes care of the concurrent access to the data by using some kind of locking. File system File system is a collection of data. In this system, the user has to write procedures to manage the database. The file system provides the representation of the data and the details of the storage of the data. There is no crash mechanism in the file system, that is, if the system crashes while entering some data, the contents of the file will be lost. It is very difficult to protect...
