Introduction
The information system project for companies is realized in relational data base "ORACLE" version 7.x, 8.x. IS project is realized in more variants and applicational platforms. The interpretation of the project depends on the company's needs, the size of the company, and the company's willingness to invest financial means into hardware. The information system project is realized in three applicational platforms:
Host applicational platform
Client server applicational platform
WEB applicational platform
Oracle database
For more than a decade, the most eminent name in the domain of relational database is the Oracle Company with its products. Oracle Corporation is the second biggest world company for production of software, and the leading world manufacturer of software for informational management of companies. Oracle Company made a significant breakthrough in the application of Internet technology for companies` information systems.
Oracle's RDBMS (Relation Database Management System) uses all of the good features that characterize a relational database. The characteristics of the Oracle's RDBMS and its related products are:
1. Security
Protection from unauthorized access to data (every user has to obtain authorization to access the database, and also the authorization for various levels of access to data in that base).
The possibility of precise defining authorization of data entry, data correction, data deleting at the lowest level of accounting, and the possibility of defining the authorization solely for inspection of data on the higher level of data.
Distribution of authorization - every manager can determine the level of accessibility of data to individual workers, or to take away his authorization.
Multilateral ways of protection against loss of data
Automatical recovery of data (after incomplete finishing of the programme, electricity cut, withdrawal from the transaction, the data returns to the level before the beginning of transaction).
2. Easier usage
Less programming - programming languages of IV generation
Readymade tools
Ad hoc reports
User's direct access to data (without the AOP mediator)
Different surveys of the same data
Graphical survey of data
Possibility of connecting with other tools
3. Reduction of redundancy
Saving of memory space in the computer
Draft of inconsistency of data
4. Competitive usage
5. Quick development of application
6. Reduction of the errors
Apart from the characteristics mentioned, Oracle database has some additional features, and that is why we have decided to use it for the realization of our products. Application of ORACLE is possible on almost all computers, and on all familiar operative systems (Oracle's software operates on computer network, on laptop computers, on PCs, on working stations, mini computers, mainframe computers, and computers for massive parallel processing). Apart from that, Oracle Company provides readymade set of tools for projecting. The reliability in processing has been proven through our eight - years application of Oracle products on different hardware and software platforms.
We will mention only a few platforms on which our products operate: SCO UNIX, IBM AIX, and Windows NT… With significant expansion of volume of work, a company would not satisfy its needs by purchasing new PCs, but, it will have to purchase new computers of medium or even higher class. If you choose ORACLE, You will not have to purchase a new project and new programs for IS backup since the programs that operate on the suggested equipment will certainly operate on other platforms as well - and it has been proven through our experience.
When expanding the system, or moving to a new hardware or software platform, You do not have to buy the already bought Oracle products, perhaps only pay some additional sum to enable the usage of those products by additional number of users (because the price of a software depends on the number of users). The important fact is, that it is not a new software purchase, but only additional payment.
Forms of cooperation
The forms of cooperation that we offer within the implementation of information system for a company are:
Installation of database software needed for functioning of information system
Installation of programs needed for functioning of information system or certain subsystems
Complete backup for introduction of information system
Complete backup for data transfer
Software training for users
Maintenance of IS project and backup program after the expiration of guarantee
Installation of database software for managing the databases
Training - school center
Consulting services concerning projecting of information systems or subsystems
Creating a new information system
Individual cooperation for certain segments of IS
Consulting services for the choice of the necessary hardware and software
Consulting services for certain operative systems
Consulting services for projection of computer networks
The dynamics of IS implementation
The dynamics of IS implementation depends on:
The type of the company based on the categorization of companies, type A Company (a small company, situated in one building), type B Company(a medium - size company with more branch offices in more than one building), type C Company (a company with more branch offices and business units situated in more than one town or in more than one country), and the volume of work.
The whole company information system
Certain subsystems, as well as the equipment that would be program implemented - those programs that backup information system - subsystem
The putting of the project into operation would be carried out earliest three moths after the signing of the contract for all subsystems for company or for branch office
The compulsory steps of the implementation are:
Verification of the proper functioning of the system's hardware and software
Presentation of the set IS project for chief managers, managers, administrators from the company
The final administrators training for certain functions of operating the program and subsystem packages.
Warranty period
We give you a twelve (12) months guarantee after signing of the acceptance contract for the IS project, in which we oblige to correct any possible vagueness or minor inaccuracy that could appear due to change of legal regulations. At the expiration of the warranty period, we sign a contract for permanent maintenance of IS, or a contract for consulting services for maintenance and development of IS.
Price
The price includes:
1. The production of the project
2. Information system model including:
Description of functions
Recommendation for the creation of indexes
Recommendation for the creation of users and menu groups
Catalogue of lists
3. base installation for the company's entire information system
4. programs for complete backup of the IS project banks for subsystems:
5. Detailed instructions for usage of the project in written form for the users or a WEB presentation of instructions
6. Complete training of certain sectors for the usage of subsystem programs
7. Delivery of object code programs for the functioning of the information system with the right to use exclusively for the needs of the company
8. Delivery of source code programs for the functioning of information system with the right to use exclusively for the needs of the bank if such an agreement has been reached.
Total price of the mentioned subsystems and the mentioned list of programs depends on the type of company, type of computers, type of operative system, and the number of workstations, as well as on the included subsystems. Similarly, the price can vary depending on the number of new programs that are not included in the standard offer, but are significantly different from the standard offer programs.
