IT Strategies

• The larger the organization, its resources &investments, the more relevant are ICT “consequences”– IT strategy must be designed according to

the organization’s goals & resources adjusted & approved by management levels

Organization objective & activity target field

Management style & strategy

Financial Resources Human Resources Policy



ICT Strategies

• ICT implementations should be adapted to:– The aim of the organization & activity

target field • different objectives and target fields

impose specific characteristics on IT strategies

– Financial resources / possibilities • the degree of willingness to invest in ICT

depends on involvement & awareness of IT benefits



ICT Strategies

• ICT implementations should be adapted to:– Human resources policy – in IT

• create proper strategies within a plan of efficient ICT implementation

• network admins, software developers, project managers

– Management style and strategy –• Integrating IT strategy into the overall

management strategy • awareness of IT efficiency



• The Working Framework– Knowledge bases society - IT impact on

learning & management processes – Integrated systems – condition for

competitiveness – Information system integration - mainly

studied for business and organizational processes

• Info systems - EU educational institutions– Educational systems –

• Developed in-house – (technical) Universities, • Acquired : U Campus, People Soft, etc.

– Administrative management – ERP systems • Mainly acquired – for example SAP

– Integration problems – Integration with the e-learning system– Integration with research systems / facilities



Proposed Solution of an integrated portal – the design of a system integration framework for providing web

services into a global portal, including web-based facilities offered by dedicated information systems

– Integration & synchronization of databases based on different technologies (php / postgresql, asp / MS sql)

– An integrated architecture based on ILM Microsoft server, and additional interface modules

• integrates the dedicated information systems into a web portal that also provides e-learning facilities, based on SharePoint Portal

• ILM can be used to synchronize and optimize data access and delegate processing means to the appropriate dedicated software components – by specific interfaces

– Adequacy to organizational IT strategy



• Integration Framework And Principles – authentication solution - maps facilities from the

dedicated information systems into the portal, for each user category - ILM type server

– the authentication server associates, to each user group, the facilities that correspond to their permissions in each of the dedicated information systems AcademicInfo, ManageAsist, Research Management System – specific interface modules

– A global synchronized database is in train of being created - human resource & organization chart

• User[userid, account, password, unitid]• Unit[unitid, unitname, …]• Organization_chart[unitid, superior_id, horiz_id]



• Integration Framework And Principles



• Integration Framework And Principles - example– database synchronisation --> data warehouse

• Example: AcademicInfo, ManageAsist, Research Management System and Portal databases

• Basic data for organizational management: organisation chart, HR

• Example: – portal – AcademicInfo: users (all categories), curricula, study

contracts, grades, fees – portal – AcademicInfo – ManageAsist: organisation chart,

units, human resources, managers, financial information – portal – AcademicInfo – Research Management System:

research activities, PhD Students – portal – ManageAsist – Research Management System:,

units, human resources, grants & corresponding financial information



• Integration Framework And Principles – Permission management

• Configures portal content for each user category• Group based • User categories - example:

– Students ( PhD students, international students): curricula content; specialization based groups

– Teachers ( teacher assistants): content management; discipline based groups

– Administrators: administration permissions; faculty based groups

– other users: secretariats, alumni, partners, etc.



• Integration Framework And Principles – 2 database management systems

• PostgreSQL for ManageAsist and Research Management System and MS SQL Server for AcademicInfo

• Global database; bi-directional synchronization • this solution ensures significant autonomy functional

advantages for information systems, compared to a direct Active Directory integration & mapping

• We are implementing a synchronous database replication, in order to obtain real time synchronization

– Asynchronous methods are also explored if the run time of the global synchronizing tends to increase too much



ILM DB (SQL Server)

AcademicInfo (SQL Server)

ManageAsist (PostgreSQL)

Research MS (PostgreSQL)

the proposed integration solution may be applied in different organizations, for integrating their dedicated information systems

Integration Framework And Principles • database synchronization • MS Identity Lifecycle Management server, has advanced integration facilities with our e-learning portal • we are configuring the necessary permission mappings from

the dedicated information systems into the authentication server by means of dedicated interfaces which transfer credentials from the portal into each system



E-learning systems - advanced tools which assist teachers in creating a cooperative, multidisciplinary and explorative learning environment and students in accessing these learning facilities and developing learning interactions within this environment • development of the student and goal centered

learning model • Information system implementation stages;

user involvement in specification, testing, implementing

• system flexibility requirements and de-centralized system administration that were pursued are expected to prove their efficiency in future developments



• Web services - E-learning services – SharePoint built in facilities

• content & schedule management and sharing • communication facilities (e-mail – OWA type,

discussion lists, etc.) • evaluation tools and feed-back facilities; task

management ; survey tools • blog and RSS tools

– The system is also open to adding new web-parts, services or components



• Web services - E-learning services

Managing an educational resource (in design permissions)



• Web Services – virtual labs – support learning in experimental sciences

and sharing experimental knowledge by electronic means in fields like: process engineering, environmental engineering, physics, chemistry, biology

• on-line virtual experiments and on-line labs; case studies based on mathematical modelling and simulation; recorded video sequences and on-line video streaming; posting material to be further processed with dedicated client
