Graduate Thesis
Topic: Methods and Reality of Information Systems design
by Using Develpoment Tools
Abstract: The objective of the thesis is to decover
problems that may have to be solved during information systems design and
that may have an impact to the relationship between an information system
and the reality it represents. The thesis introduces a new approach -
called Mosaic Approach - to data modelling. The approach enables off-line
team work over ERDs (for some development tools a team work at all).
Moreover, it offers to manage ERDs on different levels of abstraction. It
also helps in situations when the development tool's worksheet is too
small. Then, ERD is shown as ambiguous (e.g. defining integration rules).
So, an advanced notation of ERD is presented. Other chapter shows a
solution of users' access to data in the case of many users (i.e.
thousands) and need to control access to single records. The thesis also
solves some problems with proprietary logfile (to enable database recovery
and audit). Publication Survey
“Integration in Global Information Society” – a paper for
Systems Integration conference ’99
|
This article shows system integration as a
never-ending process concerning all subjects of the global society.
Origins of the process may be seen in past two or three decades. The
article stresses the necessity of existence of an electronic market
(meeting of electronic supply and demand) as an environment for
global integration of business, commerce, and state services. It
also tries to refer to opportunities and risks of the society’s
subjects. Moreover, the article is about changes in understanding
businesses and their management, relationships of employers and
employees. The attention is paid to banking and payment system that
must be seen as strategic. Global integration through public
communications is not possible without ensuring security of
electronic relationships. The article therefore wants to give a hope
of secure communication by a treatise on certificate authorities.
With chapters about impacts of the information society, the article
calls the attention to the very global (not only geographical)
character of the starting trend. Finally, problems with system
integration of independent subjects of different levels of the
society in the global scale are
mentioned. |
“Banks and Electronic Market” in Systémová integrace
4/1999
|
The article is oriented to banking. Banks are shown
as subjects of "two faces": an eterprise and a part of a national
banking system. This also is the reason why we should be interested
in banks apart. The global character of the society enables money
transfer away from banking sector. This reduces banks’ possibilities
and leads to disintermediation (disabling central bank to do
monetary policy effectively). The article shows how banks can save
their positions. Acting as intermediaries of remote payments and
guarantees of both participants in payment transactions seems to be
the best solution. It means to enable customers to communicate with
banks 24 hours a day, 7 days a week from their homes or wherever
they are. To be, or not to be (accessible via Internet)? That’s the
question discussed in the article, too. However, being non-stop
& on-line reachable requires good process architecture and
relevant information system. Besides that, the article shortly calls
attention to necessity to find a trade-off solution for central bank
supervision and non-stop operating of
banks. |
“Banking in the Information Society” – a paper for Ph.D.
Students’ Day session (2000) of Faculty of informatics and statistics
(Sborník prací doktorandů vědeckého semináře doktorského studia FIS, VŠE
Praha, 2000)
|
This article starts with one-page presentation of
global information society’s (GISo) characteristics. After this
preface, a model of GISo is proposed. The model consists of layers,
subjects, means, and architecture of subjects. There are three
layers in the model: legal & working framework, integration
& infrastructure services, and producers & consumers. The
subjects are: international organisations (UNO, OECD, EU…),
supranational organisations/associations/unions (ISF, EUROBIT,
HLSG…), certification authorities, banking sector,
telecommunications, companies, state administration/Civil
Service/government administration, and citizens. Every subject
belongs to a certain layer. However, we can see relationships
between the layers. The means of GISp are flexible global
interconnection, security (content and uniqueness of messages,
sender identification + non-repudiation of message, remote contract
signing, guaranty of quality), and common language (standards,
conventions etc.). Finally, an enhancement of enterprise information
systems architecture with emphasis on wide co-operation and
interconnection with suppliers, customers, and partners is
presented. The process of interconnecting, co-operating, and
co-opeting (co-opetition = competition + co-operation) is another
phase of system integration. --- The next part of this article is
oriented to banking. Banks are shown as subjects of two layers: the
integration & infrastructure layer and the producer &
consumer layer. Correspondence to the both layers is the reason why
we should be interested in banks apart. The global character of the
society enables money transfer away from banking sector. This
reduces banks’ possibilities and leads to disintermediation
(disabling central bank to do monetary policy effectively). The
article shows how banks can save their positions. Acting as
intermediaries of remote payments and guarantees of both
participants in payment transactions seems to be the best solution.
It means to enable customers to communicate with banks 24 hours a

“Care for Customer Not Only in Banks” in Bankovnictví
6-7/2002 a 8/2002, Economia, a.s.
|
This article discusses CRM of banks. It starts with
a short historical review that leads to the very basic assumption of
every CRM – integration of clients data in order to satisfy internal
business needs. The next section shows a little bit different
approach which is more convenient these days – it places a client
into the center of all. Business is profitable only if every
interaction with every client is profitable. To know this, companies
must reorganize themselves. After reorganization, CRM inovation may
be started. The article gives some ideas how to achieve good
results. It also presents actual data of CRM
projects. |
“Impacts of the Global Information Society on the Banking
Industry” in SSGRR 2002s conference proceedings, L'Aquila, Italy (July 29
- August 4, 2002, invited speaker)
|
The Human society has lost its borders. It is
global and it relies on information. There is almost no delay
between the time information is created and the time it is used.
There is almost no space between the place of its rise and the place
of its processing. Companies beyond our segment are becoming our
competitors. Our competitors are becoming our partners. Our clients
require new services. This paper describes what it means to banks,
the banking industry, and the currency.

“Total money electronization” in Bankovnictví
6-7/2003 a 8/2003, Economia, a.s.
(University of Ecomomics in Prague Rector's Award for Publication of PhD Students.
|
This article discusses possibilities and impacts of e-money (cashless society). There are at least two ways of money electronization. First: standalone electronic banknotes, second: no e-cash, just money on banking accounts. The first way is interesting as it is neccessary to assure e-cash will have the same functions that paper money has. The second way has strong impacts on money supply, behaviour of basic macroeconomic models (IS-LM, AS-AD), inflation, unemployment etc. The article also presents a new (pragmatic) money definition: money is a measure of what one has done for the society (and how important the society think it was). So, money is a right to draw products and services back from the society.

“Systems Re-integration in the Global Information Society” in Systémová integrace 1/2003 (May)
|
This arcticle updates systems integration scheme published in another articles. The update is based on the trend of collaboration among businesses that we can see in the global information society (GISc). In the same time, collaboration is essential for GISc. The improvement of the scheme lies in putting stress mainly on integration of businesses with their environments. The interbusiness integration consists of three steps: outer integration, inner integration, and integration of interbusiness processes. Next topic discussed in this article is systems reintegration. The principle of systems reintegration is desintegration of processes inside businesses and their integration in the global information society. This leads to narrow process specialization of businesses and creating real business networking based on full sophisticated outsourcing. Following parts of the article describe a possible problem of loosing competition advantage if core business is not well identified and/or outsourcing is applied in the field of core business.

“Trends and Problem Issues of the Business Infrastructure” in Systémová integrace 1/2003 (May)
|
The paper brings description of trends concerning the business infrastructure, i.e. communication channels, banks and their services, and intermediaries.
I have presented the trend of integration of communication channels. The economic point of view is considered in this paper as well. Next, usage of communication channels for banking services is reviewed.
Banking and banking services are the main topic of another chapter of this paper, too. Here I put stress on changes we can see in the business environment. The changes may have a radical impact on banks. Besides another topics, the paper talks about account aggregation, banking information systems management, and what banks should do in order to survive successfully, or just to survive.
Finally, I focused on intermediaries. Will they disappear? Or, will they find their place? I propose they should become what I call demand aggregators. A very special type of intermediaries are electronic marketplaces. In this paper I show they needn’t be just electronical versions of classical marketplaces. They can offer high value services to their participants. It also means they can offer payment services. This way they directly compete with banks. I discuss again how banks could behave.

“New Way of Profit Management” in Moderní řízení 7/2003
|
This article shows a new way of profit management that is based on 1:1 CRM. I have shown models for profit management being used now not to be sufficient for the global information society. There is no optimal number of products nor customers. Every relationship must be managed individualy, and hence every part of total profit must be controlled individually as well. Profit from every customer must be higher than relevant costs. In spite of this I have proposed some minimal requirements (ranges) for number of customers. Finally, I have presented that this approach of profit management is very similar to investment decision. It is important to evaluate possible risk of future income from every customer. I do not say "old" models are bad. They still work. However, their role is to describe the situation, not to be the main decision tool.

“Secure Communication and Trust in the Global Information Society” in Systémová integrace 2/2003
|
This article is an aggregation of several topics concerning safe and trusty communication in the global information society. First, an improvement of ISO/OSI (Open Systems Interconnection – Basic Reference Model, ISO/TC97/SC16) was presented. The improvement lies in adding a new layer – safety layer. Next topic describes an easy implementation of XOR logic function for getting an unbreakable encryption. Following topics are about relations between subjects. The article solves remote contract signing, discusses possible ways of assuring trust and quality via several systems of certification authorities. Finally, a solution of the problem that arises from cryptographic keys’ limited validity is proposed.

“Different Views of IS Architecture” in Systémová integrace 2/2003
|
In this article, information systems architecture is discussed. First, several contemporary approaches to architecture are presented: a typical general IS architecture, integration of existing applications, application architecture and different levels of intra- and interbusiness integration, a model of e-business management, and portal solutions. Next, a new concept is introduced. This new concept is based on processes and process management. The principle is that an information system is not a scheme of blocks of software. IS is about creating and using information and knowledge, and transforming them to long term prosperity. Hence, the IS architecture must correspond to business architecture. A new scheme of IS process architecture is shown in the article to illustrate the main idea. Also, task of systems integrators is rethought.

“Data, information, knowledge” in E-Logos, Dpt. of Philosophy, University od Economics in Prague
|
This is one of many articles discussing the topics of data, information, and knowledge. It is done with regard to the global information society which we probably are a part of. Explaining the topics does not start with data but rather with relationships among data, information, and knowledge. The article joins Shannon's definition of information, semiotics and other sources. Next, the article shows that information does not always bring less uncertainity as declared by Shannon's definition. Other topics mentioned are knowledge, emotion as an "ingredient" of information, and finally a little bit more pragmatic view of information: using information for management and relation of information to money.
