    1. 1. How (5) Supply Chains and Database connectivity Some keys concepts of e-commerce  SLIDE
    2. 2. Supply chains and databases <ul><li>Some keys concepts of e-commerce </li></ul><ul><li>In this lecture; </li></ul><ul><ul><li>An overview of database connectivity </li></ul></ul><ul><ul><li>Look at issues relating to supply chains </li></ul></ul> SLIDE  WEB
    3. 3. The Three Tier Model <ul><li>Modular design and platform independence </li></ul><ul><ul><li>The first tier – web client </li></ul></ul><ul><ul><li>The second tier servers side application </li></ul></ul><ul><ul><li>Third tier database system </li></ul></ul><ul><li>Bridge between second and third layers – Middleware </li></ul><ul><li>Databases - When ordering an item you may wish to see if it is in stock - need to connect the ordering system to the inventory system. For many businesses this means connecting legacy systems. </li></ul>Internet Database Integration Product Middleware Web-browser Web-server / application server Database [from Chan, electronic commerce]  SLIDE  WEB
    4. 4. Integration & connectivity <ul><li>If you are linking to a website chances are there will be a database behind it somewhere. </li></ul><ul><li>Many web based applications are covered by HTML files – flat file storage of data – This is likely to change as; </li></ul><ul><ul><li>Complexity of websites continues to increase </li></ul></ul><ul><ul><li>Volume of data need to be linked to the web increases, workflow messaging, EDI etc… </li></ul></ul><ul><li>Traditionally all data held in database. Examples being Oracle, Paradox, MySQL, Ingres. Other possibilities exist for the future (XML!) </li></ul> SLIDE  WEB
    5. 5. Accessing information <ul><li>Examples of systems required db connectivity varied </li></ul><ul><ul><li>AltaVista, yahoo - maintain large databases of website content </li></ul></ul><ul><ul><li>Amazon -products and orders, etc </li></ul></ul><ul><li>There are many others </li></ul><ul><ul><li>Species data – web portal – aim to produce a catalogue of life online </li></ul></ul><ul><ul><li>On-line reservations - have to place passengers from around the world on numerous flights on different dates </li></ul></ul><ul><ul><li>On line book store have to deal with title lists in the hundred thousand, and stock information, in addition to order details </li></ul></ul><ul><ul><li>Online libraries have to store millions of citations from hundreds of publications held in back end databases </li></ul></ul><ul><ul><li>Web search engines scan thousands of web pages to proved answers to searches </li></ul></ul><ul><li>Web database content can vary from DNA sequences to archaeological artefacts. </li></ul> SLIDE  WEB
    6. 6. Databases and the web <ul><li>Wednesday 20 March 2002 </li></ul><ul><li>Consignia (formerly the royal mail) is launching a service to enable Internet shoppers to save their delivery preferences to a central database. Consumers store their preferred address or drop-box location and preferred post office,when they reach the address request at the end of the shopping process they click on a button on the desktop which forwards all their details to the retailer in a secure manner. The information can be downloaded with a single click whenever they shop online. Consignia is planning to increase the functionality of the database to cover the whole delivery process. Consignia is in talks with retailers across all sectors about supporting and promoting the database, which is based on software from supplier Kinek. The database forms part of Consignia's strategy to overcome fulfilment problems, identified as a major barrier to e-commerce success. </li></ul><ul><li>[Daniel Thomas, Computer Weekly] </li></ul> SLIDE  WEB
    7. 7. Data Mining and user profiling <ul><li>Users provide information by filling in registration form online – names, address, telephone, email plus other self confessed information – including preferences </li></ul><ul><li>Shopping cart database captures items selection and purchase </li></ul><ul><li>Profile the customer – keeping records of what your preferences are and apply special offers. Allows the system to identify exactly who the customer is and what they want and try to fulfil those needs exactly </li></ul><ul><li>Combine information together – </li></ul><ul><ul><li>log file holding page request </li></ul></ul><ul><ul><li>Registration forms </li></ul></ul><ul><ul><li>Shopping cart database </li></ul></ul><ul><li>An example of data mining to collect the information required by the company for strategic reasons major patterns and purchases how can we maker it easier for people to access our site and find what they want </li></ul><ul><li>Data warehousing is adding all data to together to form warehouses containing sales payment information and any physical point of sales to provide terabyte of data on consumer behaviour on a web site. Data Mining is extracting new information / patterns from data held in the Data warehouse. </li></ul> SLIDE  WEB
    8. 8. Database Integration <ul><li>Kalakota (1996) suggested the following categories for products designed to integrate databases and the web </li></ul><ul><li>Gateways provided by the the DBMS vendors to link their DBS to the web </li></ul><ul><li>Third party gateways supporting multiple relational databases and other legacy data sources </li></ul><ul><li>Text and document databases enhanced to work over the web </li></ul><ul><li>Front-end database application tools with web access </li></ul><ul><li>Web servers and web browser with database aware features </li></ul><ul><li>CGI specification can be found at http://hoohoo.ncsa.uiuc.edu/cgi/interface.html </li></ul>[Kalakota electronic commerce a managers guide]  SLIDE  WEB
    9. 9. Database Connectivity Technology <ul><li>CGI – Common Gateway Interface - specification for communicating data between a web browser and executable programs on the web server – negotiates the movement of data between the web server and outside application </li></ul><ul><li>JDBC – Java DataBase Connectivity – An API which provide a set of interfaces and classes for database –related operations </li></ul><ul><li>ODBC – Open DataBase connectivity –allows access to data in a variety of database management systems. Adding a different driver to the ODBC system allow you to access a different DBMS </li></ul><ul><li>ASP – The key concept use scripting language to access the methods and properties of objects. ASP provides core functions that can be used to build powerful e-commerce applications – ability to add custom objects in variety of languages depending on the platform ASP can connect to any ODBC compliant database. ASP uses ActiveX Data Objects (ADO) an API . </li></ul> SLIDE  WEB
    10. 10. THE BIG PICTURE: Supply chains <ul><li>The concept of ‘value added’, a commodity is processed to create a product which is then processed further. </li></ul>Remember this?  SLIDE  WEB Mine extracts ore Steelworks process ore Steel used to fabricate components Components used to create product Sup- plier Sup- plier Sup- plier Processing Cust- omer Cust- omer Cust- omer Cust- omer Cust- omer
    11. 11. Supply chain technologies <ul><li>During the course we have looked at technologies which could be used to facilitate e-commerce and supply chain activities; </li></ul><ul><li>Electronic Data Interchange </li></ul><ul><li>Fundamentals and standards e.g. EDIFACT </li></ul><ul><li>Value Added Networks (VANS & VADS, Value Added Data Services) </li></ul><ul><li>eXtensible Mark-up Language (XML) </li></ul> SLIDE  WEB
    12. 12. Supply Chain Patterns & Trends <ul><li>Supply chain management 4 main developments; </li></ul><ul><ul><li>Simplification - They may involved any number of suppliers and level in the supply chain with varying degrees of complexity. Many manufacturers have aimed at reducing the supply chain e.g. US motor companies have reduce the number of supplier by over 50% </li></ul></ul><ul><ul><li>Use of EDI </li></ul></ul><ul><ul><li>Supply chain Management systems – flow of information to manage buying, making selling products </li></ul></ul><ul><ul><li>Collaborative commerce – expands picture to allow organisations to design and build new products. </li></ul></ul> SLIDE  WEB
    13. 13. <ul><li>Application software can be; </li></ul><ul><li>Horizontal – cross industry applications like financial management generic across all of the industries (everyone has humans resources department) </li></ul><ul><ul><li>Logistics –Purchasing, order management, distribution, inventory, warehousing </li></ul></ul><ul><ul><li>Financial -General ledger, billing budget and asset management </li></ul></ul><ul><li>Vertical – automate tasks to specific market segments. These automate tasks specific to one market segment e.g. Intel being able to track the production of a Pentium chip from order to delivery other segments include government, healthcare and education. </li></ul><ul><li>Both the vertical and horizontal markets are dominated by a small number of firms including </li></ul><ul><ul><li>SAP – German firm </li></ul></ul><ul><ul><li>Oracle (us) </li></ul></ul><ul><ul><li>Peoplesoft (US) </li></ul></ul><ul><ul><li>Baan (Dutch) </li></ul></ul><ul><ul><li>The platform of choice for these applications tends to be DEC, HP and IBM. </li></ul></ul>Supply Chain Applications  SLIDE  WEB The objective of using third party software is to avoid development costs and use the knowledge and experience of these companies
    14. 14. Supply Chain & Information <ul><li>One of the most essential items passed along a supply chain is information </li></ul><ul><ul><ul><ul><li>‘’ The bullwhip effect – erratic shifts in orders magnified up and down the supply chain ‘ </li></ul></ul></ul></ul><ul><ul><li>[Lee et al 1997, quoted in Turban et al ] </li></ul></ul><ul><li>This effect was observed by Proctor and Gamble with their disposable nappies – sales in stores were fairly constant, but distributors orders varied wildly. This caused inventory and production problems at P&G – was a result of bad forecasting by distributors, price fluctuations, order batching and rationing in the supply chain. </li></ul><ul><li>Slight demand uncertainties become magnified if managers at each level keep an eye to their own interest, the result is stock piling at numerous places in the chain </li></ul><ul><li>1998 – study in US $30 billion saving in the grocery industry if more information was shared between entities in the supply chain. </li></ul> SLIDE  WEB
    15. 15. Supply Chains and Technology <ul><li>The following e-commerce approaches and technologies help solve some of issues associated with Supply Chains; </li></ul><ul><li>Order taking using EDI, EDI / Intranet </li></ul><ul><li>Electronic payment can expedite the order fulfilment cycle payment processing can be cheaper and fraud better controlled </li></ul><ul><li>Inventories can be reduced (cash tied up in stock computing – stuff devalues fast-) can use make to order (pull production process)) </li></ul><ul><li>Order fulfilment can become instant for digital products (e.g. software) interfacing with back office system saves time </li></ul><ul><li>Collaborative commerce among the member of the supply chain can include product demand to supply forecasting reduce supply times administrative delays and work interruptions and administrative costs </li></ul> SLIDE  WEB
    16. 16. Supply Chain and B2B <ul><li>Recent study Has shown that B2B transactions less than ideal; </li></ul><ul><li>51% companies surveyed B2B mostly or absolutely failed to meet expectations. Expectations unrealistic? </li></ul><ul><li>Expect to connect at one point and link to all partners? – however B2B is not plug and play – partners need to be linked as well, need to understand benefits and technology </li></ul>[From B2B exchanges fail to deliver computer weekly 29 th November 2001]  SLIDE  WEB
    17. 17. Supply Chain - Advantages <ul><li>Most supply chains have some inefficient duplication of the processes of picking, packing, storing, and shipping. By effectively removing duplication in the supply chain, a business can decrease costs, improve order turnaround and customer service levels. </li></ul><ul><li>business may benefit in the following ways: </li></ul><ul><ul><li>Reduction in inventory levels. </li></ul></ul><ul><ul><li>Lower inventory costs. </li></ul></ul><ul><ul><li>Faster order turnaround. </li></ul></ul><ul><ul><li>Lower product prices. </li></ul></ul><ul><ul><li>Integration. </li></ul></ul><ul><li>In some cases Virtual Fulfilment is when your business reduces stocks completely, and enters an agreement for all orders to be shipped direct from a third party fulfilment house or from the manufacturer to the end customer. While this is possible in many industries, it requires the co-operation of the various channel players to work effectively and an integrated e-business platform. </li></ul><ul><li>[IBM (New Zealand) - website] </li></ul> SLIDE  WEB
    18. 18. Supply Chain Savings (1) <ul><li>Supply chain management has huge implications – </li></ul><ul><li>GlaxoSmithKline (pharmeuticals) has installed a new web based supply chain system to track supplies – generate forecasts and reduce errors </li></ul><ul><li>- communication with external suppliers something of a problem as there was no standard order form and some where hand written and illegible! </li></ul><ul><li>The system cost $500K, to handle 1M transactions per year. In one year this has saved $3M – enabled to reduce the stock levels by 1week! </li></ul><ul><li>[Maggie Holland, Computing 7 th Feb. 2002] </li></ul> SLIDE  WEB
    19. 19. Supply Chain Savings (2) <ul><li>Littlewoods Stores introduced a web based linked to a data warehouse to improve it’s supply chain by allowing financial and stock information to be review on a daily basis; the following savings were made; </li></ul><ul><ul><li>Reduce inventory expenses £2.6m </li></ul></ul><ul><ul><li>Strategically price merchandise in different stores £0.8m </li></ul></ul><ul><ul><li>Reduce the need for stock liquidation £0.9m </li></ul></ul><ul><ul><li>Marketing distribution expenses £4.6m </li></ul></ul><ul><ul><li>Reduction in logistics staff £0.6m </li></ul></ul><ul><ul><li>Total saving £9.6m </li></ul></ul> SLIDE  WEB
    20. 20. Supply Chain Savings (3) <ul><li>Clothing retailer New Look has implemented a merchandising management system for its 500 stores. The single, integrated system has reduced the supply chain length to six weeks - compared to the industry average of nine to 12 months – and has significantly reduced inventory levels. </li></ul><ul><ul><ul><li>&quot;It made tremendous sense to merge the accessories and clothing businesses and we needed a single collaborative solution to support this transition,&quot; he said. &quot;The new, improved supply chain has yielded substantial benefits. Primarily, even with increased volumes of product passing through the warehouse, we have reduced inventory. Total stock cover has been reduced and the distribution centre is now only holding one and a half week's stock cover.“ Alan Osborne, Logistics Director, New Look. </li></ul></ul></ul><ul><li>A rival store, Peacocks, is planning to implement both merchandising and customer relationship management software, the company has has 360 stores across the UK, and hopes the changes will help it determine which ranges of clothing should be stocked in various parts of the country, thus maximising profitability and reducing markdowns. [from: Computer Weekly Article Thursday 6 February 2003 Clothing store slashes its supply chain length ] </li></ul> SLIDE  WEB
    21. 21. Just in Time… <ul><li>JiT supply chain management – operated by large number’s EDI companies, there are security issues / problems if the chain is disrupted. As the following examples show the effect of disrupting a supply chain; </li></ul><ul><li>Fuel blockade in September 2000 – people could not get to work distributors could not distribute shops run low bread milk etc panic buying – despite / because of media </li></ul><ul><li>9.30am 4 th January 1991 an AT&T repair crew in Newark, New Jersey U.S.A. accidentally sever a fibre optic cable carrying 100,000 calls. The effects included; </li></ul><ul><ul><li>Downtime of the New York Mercantile Exchange </li></ul></ul><ul><ul><li>FAA control lost to New York Metropolitan Area resulting in lengthy flight delays </li></ul></ul><ul><ul><li>60% calls to New York City blocked. </li></ul></ul> SLIDE  WEB

    26. 26. Retail exchanges <ul><li>The World-Wide Retail Exchange has saved its members more than £425m since its launch in March 2000, the online business-to-business exchange for retailers and suppliers has revealed. B2B exchanges were expected to revolutionise the way organisations bought goods from suppliers, offering substantial cost and time savings, but many have fallen by the wayside in the past two years The WWRE, which now has 62 members including Tesco, Kingfisher and Marks & Spencer, has survived because it has adapted to changing market conditions and listened to feedback from users. </li></ul><ul><li>&quot;In the early days auctions were all about price. But buyers are becoming more sophisticated taking other factors into consideration, such as terms, quality and delivery timescales. Companies are still reaping the financial benefits though - every single member has achieved savings.&quot; Initial auctions tended to be for goods not for resale - such as office supplies and sanitary products - but this has also changed. Now more than half of the goods that are purchased through WWRE auctions are for re-sale. This allows savings with supply chain rationalisation instead of buying the same goods from a number of different suppliers.&quot; The WWRE recently upgraded its auction software to a multidimensional auction tool which allows buyers to focus on key purchasing factors other than price. Joining WWRE does not represent a burden for the IT department from the retailer or manufacturer, Williams added. &quot;We operate an ASP [application service provider] model, so there is no integration with other systems - all you need is a browser. There is nothing downloaded on to the client, all the information is stored on the server.“ </li></ul><ul><li>[From Computer Weekly Friday 31 January 2003 Retail B2B exchange delivers £425m savings] </li></ul> SLIDE  WEB
