What are the two types of distributed data processing?
What Are the Types of Distributed Data Processing? There are primarily two types of it. Batch Processing & Real-time streaming data processing.
What are Web databases and distributed databases?
A distributed database (DDB) is an integrated collection of databases that is physically distributed across sites in a computer network. A distributed database management system (DDBMS) is the software system that manages a distributed database such that the distribution aspects are transparent to the users.
What are examples of distributed processing?
Examples of distributed systems and applications of distributed computing include the following:
- telecommunication networks: telephone networks and cellular networks,
- network applications: World Wide Web and peer-to-peer networks,
- real-time process control: aircraft control systems,
- parallel computation:
What are the 5 parts of data processing?
Data Processing Cycle
- Step 1: Collection. The collection of raw data is the first step of the data processing cycle.
- Step 2: Preparation.
- Step 3: Input.
- Step 4: Data Processing.
- Step 5: Output.
- Step 6: Storage.
What are the types of distributed database?
Distributed Database System
- Types:
- Homogeneous Database: In a homogeneous database, all different sites store database identically.
- Heterogeneous Database:
- Distributed Data Storage :
- Replication –
- Fragmentation –
- References :
What is homogeneous distributed database?
A homogenous distributed database system is a network of two or more Oracle databases that reside on one or more machines. For example, a single query from a Manufacturing client on local database MFG can retrieve joined data from the PRODUCTS table on the local database and the DEPT table on the remote HQ database.
What are the objective of distributed query processing?
Objectives of Distributed Query Processing The main objectives of query processing in a distributed environment is to form a high level query on a distributed database, which is seen as a single database by the users, into an efficient execution strategy expressed in a low level language in local databases.
What do you need to know about distributed processing?
Distributed Processing This chapter defines distributed processing and describes how the Oracle server and database applications work in a distributed processing environment. This material applies to almost every type of Oracle database system environment. This chapter includes: Introduction to Oracle Client/Server Architecture
How is data managed in a distributed database?
The data at each site is under the control of DBMS and managed by DBMS. The Distributed processing is centralized database that can be accessed over a computer network by different sites.
What happens in a heterogeneous distributed database system?
In a heterogeneous distributed database, different sites can use different schema and software that can lead to problems in query processing and transactions. Also, a particular site might be completely unaware of the other sites. Different computers may use a different operating system, different database application.
Which is an example of distributed processing in Oracle?
Distributed processingis the use of more than one processor to perform the processing for an individual task. Examples of distributed processing in Oracle database systems appear in Figure 6-1. In Part A of the figure, the client and server are located on different computers; these computers are connected via a network.
