The database record can be thought of as a row of information within a database table.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The Database<\/h2>\n\n\n\n<p>A database is a set of data arranged in a way that a computer program can immediately choose the required portions of data.&nbsp; It is often called DB.<br>A common database can be compared to a filing system which is arranged by fields, records, and files.&nbsp; A field is a specific piece of data; a record is a total set of fields, and a file is a group of records.&nbsp; For example, a phone book can be considered a file with a list of records.&nbsp; Each record has the following fields: name, address, and phone number.<br>A database management system (DBMS) is used to obtain data from a database.&nbsp; DBMS is a selection of programs that allows the user to input, arrange, and choose data from a database.&nbsp; There are distinct kinds of DBMS, from small systems that perform on personal <a class=\"wpil_internal_link\" style=\"display: inline !important; width: auto !important;\" data-wpil-post-to-id=\"13\" href=\"http:\/\/teachcomputerscience.com\/fundamentals-of-computer-systems\/\" target=\"_blank\" rel=\"noopener noreferrer\">computers to large systems<\/a> that perform on mainframes.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The Record<\/h2>\n\n\n\n<p>A record is a group of data saved in a table.&nbsp; It is a set of fields, like an employee\u2019s job record as shown below.<\/p>\n\n\n\n<figure class=\"wp-block-table rcp-table\"><table><thead><tr><th><strong>Employee ID<\/strong><\/th><th><strong>Last Name<\/strong><\/th><th><strong>First Name<\/strong><\/th><th><strong>Position<\/strong><\/th><th><strong>Department<\/strong><\/th><th><strong>Hire Date<\/strong><\/th><\/tr><\/thead><tbody><tr><td>00108<\/td><td>Doe<\/td><td>John<\/td><td>Assistant Manager<\/td><td>Human Resources<\/td><td>November 16, 2000<\/td><\/tr><tr><td>00109<\/td><td>Parker<\/td><td>Anne<\/td><td>Supervisor<\/td><td>Financial Services<\/td><td>May 1, 2003<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>A record in a database is an object that can have one or more values.&nbsp; Groups of records are then saved in a table; the table determines the data that each record may have.&nbsp; Various tables hold various records in a database.<br>A new record produces a new row in the table that\u2019s why records are oftentimes labeled as rows.&nbsp; Separate fields are referred to as columns because they are identical for every record in the table.&nbsp; Record and row can be utilized mutually, but nearly all database management systems utilize rows for error messages and queries.<br>Records provide a practical way to save and pull out data from the database.&nbsp; Each record can have diverse types of data, and thus a single row could have several kinds of information.<br>Records can be easily created, altered, and erased without affecting other data in the database.<br>An ideal database design should have a primary key for the table.&nbsp; A primary key is a unique field in each record in a database.&nbsp; In an employee\u2019s job record sample above, the Employee ID is the primary key.<br>A group of records can be called a file, data set, or table.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Advantages of Using a Database<\/h2>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Significant time savings<\/strong> \u2013 Fetching a single record can be done in a just a few clicks. Merging database records can be done in an instant.<\/li><li><strong>More handy information<\/strong> \u2013 Creating and running a query can be done easily to seek for distinct answer or record from the database.<\/li><li><strong>Capacity to connect data<\/strong> \u2013 Different sources of information can be linked together to review performance.<\/li><li><strong>Ability to stimulate mail, email and social media<\/strong> \u2013 Mass customisation in terms of specific response to potential customers depending on interpreted customer information.

Design and development is an intricate endeavour.<\/li><li><strong>Cost<\/strong> \u2013 Database requires considerable one-time and continuous financial resources. Database management system customisations would include periodic modifications that has cost implications.<\/li><li><strong>Security<\/strong> \u2013 There is a need to ensure that database systems can safely save data including confidential information. High security against viruses and hacking is required.<\/li><li><strong>Compatibility<\/strong> \u2013 There is a possibility that a database management system might not be suitable with a company\u2019s functional requirements. Scalable database management systems that are being offered nowadays may resolve this issue.<\/li><\/ul>\n\n\n\n<h3 class=\"gb-headline gb-headline-a9427c80 gb-headline-text\">Further Readings:<\/h3>\n\n\n\n<ul class=\"wp-block-list\"><li><a href=\"https:\/\/en.wikipedia.org\/wiki\/Record_(computer_science)\" target=\"_blank\" rel=\"noopener\">Record (computer science)<\/a><\/li><\/ul>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/teachcomputerscience.com\/wp-content\/uploads\/2019\/08\/032-data.png\" alt=\"A database record is a collection of fields about the same person, item, or object in a database.\" class=\"wp-image-5956\" width=\"297\" height=\"297\" title=\"\" srcset=\"https:\/\/teachcomputerscience.com\/wp-content\/uploads\/2019\/08\/032-data.png 512w, https:\/\/teachcomputerscience.com\/wp-content\/uploads\/2019\/08\/032-data-150x150.png 150w, https:\/\/teachcomputerscience.com\/wp-content\/uploads\/2019\/08\/032-data-300x300.png 300w\" sizes=\"auto, (max-width: 297px) 100vw, 297px\" \/><\/figure><\/div>\n","protected":false},"excerpt":{"rendered":"<p>A database record is a collection of fields about the same person, item, or object in a database.
