Its main role is to receive requests from client machines, search for the required data, and pass back the results.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The DBMS provides database server functionality, and some DBMSs (e.g., MySQL) provide database access only via the&nbsp;<strong>client-server model<\/strong>. Other DBMSs (such as SQLite) are used for embedded databases.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Clients access a database server through a&nbsp;<strong>front-end application<\/strong>&nbsp;that displays the requested data on the client machine, or through a&nbsp;<strong>back-end application<\/strong>&nbsp;that runs on the server and manages the database.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The&nbsp;<strong>ODBC<\/strong>&nbsp;(Open Database Connectivity) standard provides the API allowing clients to call the DBMS. ODBC requires necessary software on both the client and server sides.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In a\u00a0master-slave model, the database master server is the primary data location. Database slave servers are replicas of the master server that act as proxies.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"database-server-examples\">Database Server Examples<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The following is a list of some well-known and widely used <a href=\"http:\/\/123webhostingindia.com\">database servers<\/a>. The list is not exhaustive and there are many other solutions on the market.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"my-sql\">MySQL<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">MySQL is an\u00a0<strong>SQL-based<\/strong>\u00a0open-source\u00a0Relational Database Management System (RDBMS). MySQL comes in a free and paid version, and it supports Linux and Windows. The system offers native, real-time analytics and unified service for OLAP and\u00a0OLTP databases.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The free version offers most of the necessary functionalities and has&nbsp;<strong>several available user interfaces<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"postgre-sql\">PostgreSQL<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">PostgreSQL is an advanced object-relational DBMS. PostgreSQL was designed to allow users to add\u00a0<strong>custom functions<\/strong>\u00a0using different programming languages, including\u00a0<a href=\"https:\/\/phoenixnap.com\/glossary\/c-programming-language\" target=\"_blank\" rel=\"noreferrer noopener\">C<\/a>\/C++, Java, etc.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">PostgreSQL supports Windows and Linux, and its characteristics are excellent&nbsp;<strong>data security and fast data retrieval<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"microsoft-sql-server\">Microsoft SQL Server<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Microsoft SQL Server\u00a0is a relational database management system primarily used to\u00a0<strong>store and retrieve data<\/strong>\u00a0requested by other applications. MSSQL Server allows many users to\u00a0<strong>access the same database concurrently<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Microsoft\u2019s SQL Server supports several programming languages, such as\u00a0Assembly, C\/C++, Linux, and operates on Windows and Linux.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"sq-lite\">SQLite<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">SQLite is an\u00a0open-source database management system\u00a0written in the C programming language. SQLite stores data to a text file on a device. It is widespread and supports Mac, Windows, and Linux operating systems.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">SQLite is suitable for&nbsp;<strong>small or medium-size databases<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"ms-access\">MS Access<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Microsoft Access is a database management system that allows users to store information for\u00a0<strong>reference, reporting, and analysis<\/strong>. Microsoft Access helps users analyze large data sets and manage the data better than Microsoft Excel or other spreadsheet applications.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Popular examples of database server software include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Microsoft SQL Server:<\/strong> A relational database management system developed by Microsoft, commonly used for enterprise applications and web services on Windows Server environments.<\/li>\n\n\n\n<li><strong>MySQL:<\/strong> An open-source relational database management system, widely used for web applications, content management systems (CMS), and e-commerce platforms.<\/li>\n\n\n\n<li><strong>Oracle Database:<\/strong> A commercial relational database management system developed by Oracle Corporation, known for its robustness, scalability, and advanced features for enterprise applications.<\/li>\n\n\n\n<li><strong>PostgreSQL:<\/strong> An open-source object-relational database management system, known for its extensibility, SQL compliance, and advanced features for data analysis and performance optimization.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Database Server Definition A database server is a machine running database software dedicated to providing database services.
