Ε.Μ.Π.Ι. Βασιλείου --- Electronic Commerce Εισαγωγή Communication management: an example The TCP/IP protocol: –Developed by a Department of Defense (DOD) research project to generate a network of networks (the "Internet"). –IP (Internet Protocol): Part of the Network layer of the OSI model, Uses a four byte destination address (the IP number, e.g ). –Numbers are assigned by the Internet authorities and granted by the organization. An IP router decides where a packet is sent next, by the "clockwise" algorithm, by alternating among algorithms or by identifying least busy links. –TCP (Transmission Control protocol): Part of the transport layer, responsible for verifying the correct delivery of data from client to server; the TCP packet has a header with meta-information about the packet; a socket is a package of subroutines that provide access to TCP/IP on most systems.

Ε.Μ.Π.Ι. Βασιλείου --- Electronic Commerce Εισαγωγή Electronic Data Interchange (EDI) EDI is a standard of computer to computer interchange of business documents in a machine-readable form. Leading EDI standards: EDIFACT [BERGE91] (Europe) and ANSI X12 [HAMILTON93] (North-America). A common EDI scenario: –A customer sends an EDI purchase order to a provider (transaction 850). –The provider returns a purchase order acknowledgment to the customer (transaction 855). –At ship time, the provider sends the customer an EDI advance ship notice (ASN) stating the goods to be shipped (transaction 856). –Once the goods have been shipped and billing has been processed, the provider sends the customer an EDI invoice (transaction 810). –The customer sends payment information to its bank, which wires funds to the provider’s bank through electronic funds transfer (EFT) or financial EDI.
Ε.Μ.Π.Ι. Βασιλείου --- Electronic Commerce Εισαγωγή EDI (semi) structure Components of an EDI message: –data element: a datum identified by a reference number. Examples: date, price, purchase order number, quantity on order. –data segment (or: segments): a sequence of data elements. For example, a purchase order segment consists of part number, part description, quantity, unit of measure and cost. –transaction set (or message): a set of data segments. For example, an invoice (ASC X12 set number 810). –functional group: a set of similar transactions. –Syntax rules: specifying the grammar for EDI dialogue.
Ε.Μ.Π.Ι. Βασιλείου --- Electronic Commerce Εισαγωγή Expressing EDI messages EDI can be expressed using OEM [PAPAKONSTANTINOU95]. Each functional group is represented as a graph: –internal nodes are complex values (e.g., transaction sets). –leaf nodes are atomic values of data elements. –edges represent semantic relationships and are labeled for naming purposes. An example
Ε.Μ.Π.Ι. Βασιλείου --- Electronic Commerce Εισαγωγή SHARED DATABASES –distributed - autonomous and heterogeneous information sources, web databases, electronic catalogues, directories, middleware, servers, etc. CO-OPERATIVE APPLICATIONS –CSCW, collaborative work, interoperability, intelligent agents, workflows, LEGAL and REGULATORY ISSUES –Intellectual Property Rights (IPR), electronic copyright, –Consumer Protection --- Linguistic and Cultural Issues –Regulation for: Security, Content, Cross-Border ENABLING TECHNOLOGIES
Ε.Μ.Π.Ι. Βασιλείου --- Electronic Commerce Εισαγωγή Data sources E-Commerce involves massive data transfer among systems. This data is stored, in an electronic form, in data sources.

Ε.Μ.Π.Ι. Βασιλείου --- Electronic Commerce Εισαγωγή Structured data database schemaA database is a collection of data items, whose structure is defined by a schema (e.g., a relational schema). Database Management System DBMSA Database Management System (DBMS) is a generic system, which supports the construction and access of a database; in particular: –sets up a scalable implementation data model –provides a data model (e.g., a relational data model) for defining the schema of a database –provides a basic set of operations for accessing and updating the database (e.g., relational algebra). –offers a variety of other services, such as concurrency control and error recovery.
Ε.Μ.Π.Ι. Βασιλείου --- Electronic Commerce Εισαγωγή Semi-structured data Here data have some structure, for example, –HTML/DHTML/XML files –HTML/DHTML/XML files -- consist of text interleaved with HTML formatting commands –Literature files –Literature files -- have a syntax for references, but the “atoms” of that syntax, such as paper titles, are text –Source code files –Source code files -- based on the syntax of some programming language –Electronic Data Interchange transmission –Electronic Data Interchange transmission -- based on standards.
