Define data ? What are the source of data
Answers
Answer:
Explanation:
In computer programming, source data or data source is the primary location from where data comes. The data source can be a database, a dataset, a spreadsheet or even hard-coded data. When data is displayed, it is retrieved from its data source.
A data source, in the context of computer science and computer applications, is the location where data that is being used come from. In a database management system, the primary data source is the database, which can be located in a disk or a remote server.
For maximum data integrity, a SQL database, such as MySQL, PostgreSQL, or MariaDB, is usually preferred. At the sacrifice of some performance, it provides maximum data and transaction integrity. For speed and scalability, a NoSQL data store, such as Redisor MongoDB, may perform better. These databases may not perform well with many concurrent writes, but they can read data at high speed. A lightweight version of MySQL, SQLite, is easy to set up and use, and provides excellent performance
Databases remain the most common data sources, as the primary stores for data in ubiquitous relational database management systems (RDBMS). In this context, an important concept is the Data Source Name (DSN). The DSN is defined within destination databases or applications as a pointer to the actual data, whether it exists locally or is found on a remote server (and whether in a single physical location or virtualized.) The DSN is not necessarily the same as the relevant database name or file name
