How many relations may exist between two tables in a MS Access database?
only one relationship can exists between two tables in the MS ACCESS software
What are the importance of table form query in database?
In database system the data is stored in the form of table. So to store the data in the database, table are very important in a database system.
What does a primary key do?
A primary key is a unique identifier for a record in a database table, ensuring that each entry is distinct and can be accurately referenced. It prevents duplicate records and enforces data integrity by establishing a reliable way to access and manipulate data. Additionally, a primary key can facilitate relationships between different tables in a relational database.
Functions and importance of conceptual modelling?
To represent data in an understandable way.Enhance an individuals understanding of the database.Facilitate efficient conveyance of database details between database stakeholdersProvide a point of reference for database designers to extract database specificationsDocument the database for future reference and provide a means for collaboration
What are application for distributed database?
A distributed database is a database in which portions of the database are stored on multiple computers within a network. Users have access to the portion of the database at their location so that they can access the data relevant to their tasks without interfering with the work of others. A centralized distributed database management system manages the database as if it were all stored on the same computer.

What is centralized database?
Distributed and Centralized Databases Distributed data is defined as collection of logically distributed database which are connected with each other through a network. A distributed database management system is used for managing distributed database. Each side has its own database and operating system.A centralized database has all its data on one place. As it is totally different from distributed database which has data on different places. In centralized database as all the data reside on one place so problem of bottle-neck can occur, and data availability is not efficient as in distributed database. Let me define some advantages of distributed database, it will clear the difference between centralized and distributed database.Users can issue commands from any location to access data and it does not affect the working of database. Distributed database allows us to store one copy of data at different locations. Its advantage is that if a user wants to access data then the nearest site (location) will provide data so it takes less time.There are multiple sites (computers) in a distributed database so if one site fails then system will not be useless, because other sites can do their job because as I earlier said that same copy of data is installed on every location. You will not find this thing in centralized database.Any time new nodes (computers) can be added to the network without any difficulty.Users do not know about the physical storage of data and it is known as distribution transparency, as we know that ideally, a DBMS must not show the details of where each file is stored or we can say that a DBMS should be distribution transparent.
What is Distributed Database. Why Distributed Databases. Discuss.?
(computer science) A database maintained in physically separated locations and supported by a computer network so that it is possible to access all parts of the database from various points in the network.

What are the advantage of distributed database over centralized database?
The database can be of two types either distributed or centralized . In distributed database the data is in different systems. In centralized database the data is in a single central system.We can categorize database as either distributed or centralized . In centralized database the data is in a single centralized system. While In distributed database the data is in different systems .

What does a large distributed database present in terms of security problems?
A large distributed database presents several security problems, such as data breaches, unauthorized access, data leaks, and data inconsistency. Ensuring secure communication between nodes, access control, encryption, and regular security audits are essential to mitigate these risks. Additionally, managing user authentication, authorization, and ensuring compliance with data protection regulations become more complex in a distributed environment.
Difference between parallel and distributed database?
Centralized Systems: A modern, general-purpose computer system consists of one to a few CPUs & a number of device controllers that are connected through a common bus that provides access to shared memory. The CPUs have local cache memories that store local copies of parts of the memory, to speed up access to data. Each device controller is in charge of a specific type of device (for example, a disk drive, an audio device, or a video display). The CPUs & the device controllers can execute concurrently, competing for memory access. Cache memory reduces the contention for memory access, since it reduces the number of times that the CPU needs to access shared memory.In a distributed database system, the database is stored on several computers. The computers in a distributed system communicate with one another through various communication media, such as high-speed networks or telephone lines. They do not share main memory or disks. The computers in a distributed system may vary in size & function, ranging from workstations up to mainframe systems.The main difference between centralized & distributed databases is that the distributed databases are typically geographically separated, are separately administered, & have slower interconnection. Also in distributed databases we differentiate between local & global transactions. A local transaction is one that accesses data only from sites where the transaction originated. A global transaction, on the other hand, is one that either accesses data in a site different from the one at which the transaction was initiated, or accessed data in several different sites.
Difference between database and distributed database?
A database is nothing but simply a collection of records. The data can be stored all at a same place or can be distributed in different systems . When data is stored in different places that is distributed it is called distributed database.A database is normally stored in one place. That could be a physical location, like a particular office. A distributed database is one database that has different parts of it stored in different places. This is often for security and safety purposes. To a user, they still see all of the data they need on their screen, so they don't even realise that it is stored in different locations.
What is Service primitives in computer network?
PRIMITIVES means operations.A service in a computer network consists of a set of primitives.The primitives are to be used by the user to access the service.The primitives asks the service to do some action or to report on an action.The primitives are system calls.The primitives varies for different services.The following are some of the primitives used in a computer network. LISTEN means the block is waiting for an incoming connection. CONNECT means to establish a connection. RECEIVE means the block is waiting for an incoming message. SEND means to send a message. DISCONNECT means to terminate a connection.
What is database in access?
An Access database is a relational database contained in a single file that you can upload to a directory on your Web server. People typically create an Access database file using Microsoft Access or FrontPage.

Components of distributed database management system?
=A database physically stored in two or more computer systems. Although geographically dispersed, a distributed database system manages and controls the entire database as a single collection of data. If redundant data are stored in separate databases due to performance requirements, updates to one set of data will automatically update the additional sets in a timely manner.==Read more: [http://www.answers.com/topic/distributed-database#ixzz2R7Aof5Cb http://www.answers.com/topic/distributed-database#ixzz2R7Aof5Cb]=
