Database Environments Assignment Two By Benjamin Turner 5/22/2017 What’s Covered • Different Database Models • What is a Commercial Environment • Commercial Database Environment • • • • Costs incurred Database Hardware and Software Maintenance Training • Integrating Platforms and Systems • Impact of Database to Commercial Companies 5/22/2017 What’s Covered • What is a Non-Commercial Environment • Non-Commercial Database Environment • • • • Costs incurred Database Hardware and Software Maintenance Training • Integrating Platforms and Systems • Impact of Database to non-Commercial Companies 5/22/2017 What are Databases? In computing, a database can be defined as a structured collection of records or data that is stored in a computer so that a program can consult it to answer queries. 5/22/2017 Different Database Models • Hierarchical Model The hierarchical database model is an inverted tree-like structure. The tables of this model take on a child-parent relationship. Each child table has a single parent table, and each parent table can have multiple child tables. 5/22/2017 Hierarchical Model 5/22/2017 Different Database Models • Network Model The network database model is essentially a refinement of the hierarchical database model. The network model allows child tables to have more than one parent, thus creating a networked-like table structure. Multiple parent tables for each child allows for manyto-many relationships, in addition to one-tomanyrelationships 5/22/2017 Network Model 5/22/2017 Different Database Models • Relational Model The relational database model improves on the restriction of a hierarchical structure, not completely abandoning the hierarchy of data, as shown in. Any table can be accessed directly without having to access all parent objects 5/22/2017 Relational Model 5/22/2017 5/22/2017 What is a Commercial Database? A Commercial Database is used by a commercial Company to store and query data. This data can be customer’s, Employees, Stock details and any other data the company needs to store in their operations. The Commercial Company is created with profit in mind and uses the database for its commercial values. Theses types of databases can have a small amount of involvement in the company’s operations or the company can fully rely on the database’s functionality for its operations. 5/22/2017 Different Commercial Databases Online • • • • • • Internet Search Engines Online Catalogs Mobiles Phone Sales Property Sales Marketing and Advertising Online Retail Shopping 5/22/2017 Internal • • • • • • Employees Records Customers Records Stock Details Finances Details Counter Till Operations Statistics Details Database Costs Incurred Hardware • • • • • • • • • Servers Storage (Hard drives) Routers Switches Printers and Scanners Online (Internet) Computer systems Cabling Infrastructure WAN Infrastructure 5/22/2017 • • • • • • • • Software Bespoke Applications Enterprise One (Accounts) Oracle (Database software) Networking Software Operating Systems Anti Virus Firewalls (Network Security) Databases Costs Incurred • • • • Maintenance Replacement of Components Replacement of New systems IT Technicians (Carrying out maintenance tasks) Networks Manager (maintaining network infrastructure) 5/22/2017 • • • • • Training Systems training Database training (Using the database's interface) Application training (Using office types software) Operational Training (Specific training) Health and safety Integrating Systems and Platforms Systems • • • • • • • • Orders Tele Sales HR department Support Marketing Dispatch Finance Management 5/22/2017 • • • • • • Platforms Application Operating system Networks Operating systems Bespoke Hardware compatibility Security (Firewall and Anti Virus protection) Advantages & Disadvantages Advantages • Reduced data redundancy • Reduced updating errors and increased consistency • Greater data integrity and independence from applications programs • Improved data access to users through use of host and query languages • Improved data security • Reduced data entry, storage, and retrieval costs • Facilitated development of new applications program 5/22/2017 Disadvantages • Database systems are complex, difficult, and time-consuming to design • Substantial hardware and software start-up costs • Damage to database affects virtually all applications programs • Extensive conversion costs in moving form a file-based system to a database system • Initial training required for all programmers and users What is a Non-Commercial Environments ? This policy, mainly extracted from law of Great Britain and Canada, addresses the conditions that an entity must meet to qualify as a nonprofit organization for purposes of the non-commercial licensing. When determining whether an entity is a non-profit organisation, the entity must meet all of the following conditions: •It was organised solely for non-profit purposes. •It is in fact operated solely for non-profit purposes. •It does not distribute or otherwise make available for the personal benefit of any member any of its income. 5/22/2017 Non-Commercial Database Environments • • • • • • Members Clubs Libraries Fundraising Groups Charities Non-commercial radio stations Community News papers 5/22/2017 Databases Costs Incurred Hardware • • • • • Servers Routers Modems Computer systems Cabling (Ethernet) 5/22/2017 Software • Database MySQL (Free database software) • Operating Software (Possibly Licensed) • Application (Open Office Free software) • Security (Anti-Virus and Firewalls) Integrating systems and platforms Systems • Fundraising Department • Members Details • Event and project details • Sponsors Details 5/22/2017 Platforms • Application • Operating system • Networks Operating systems • Bespoke • Hardware compatibility • Security (Firewall and Anti Virus protection) Databases Overview As discussed in this presentation, the database is a very important tool to all types of organisations. The database helps each type of organize their required data for their individual operational requirement. Database management system has become an important tool to the commercial environment, because of the requirements of the commercial company’s operations, and has become a valuable tool in today’s commercial market. 5/22/2017 Referencing http://www.dotnetspider.com/Database-Tutorial-122.aspx http://alkaline.vestris.com/docs/alkaline/vestris-noncommercial.html http://www.unixspace.com/context/databases.html Please see Database Environments Report By Benjamin Turner 5/22/2017
