Figure 1 : ACE Enterprise Integratr, author : ALEXANDER CIMBAĽÁK,2010 4.2 SAP The name SAP is acronym for Systems, Applications and Products in Data Processing. It is an extremely complicated system where no one individual can understand all of it. It runs on a fourth generation programming language called Advance Business Application Programming (ABAP). It have many of the features of other modern programming languages such as the familiar C, Visual Basic, and Power Builder. The programs name conventions begins with a letter yxxx or zxxx. SAP graphical user interfaces (SAP GUI) runs on Windows / NT / Unix / AS400. SAP have move towards the Windows Explorer Screen Format (all the Menu on the left of your screen).SAP is also an enterprise resource planning (ERP) software product capable of integrating multiple business applications, with each application representing a specific business area. These applications update and process transactions in real time mode. It has the ability to be configured to meets the needs of the business.[3] 4.3 GIS Geographic Information System (GIS) is a computer based information system used to digitally represent and analyse the geographic features present on the Earth' surface and the events (non-spatial attributes linked to the geography under study) that taking place on it. The meaning to represent digitally is to convert analog (smooth line) into a digital form. 5
"Every object present on the Earth can be geo-referenced", is the fundamental key of associating any database to GIS. Here, term 'database' is a collection of information about things and their relationship to each other and 'geo-referencing' refers to the location of a layer or coverage in space defined by the co-ordinate referencing system. It is an information system designed to work with data referenced by spatial / geographical coordinates. In other words, GIS is both a database system with specific capabilities for spatially referenced data as well as a set of operations for working with the data. It may also be considered as a higher order map. GIS technology integrates common database operations such as query and statistical analysis with the unique visualization and geographic analysis benefits offered by maps. These abilities distinguish GIS from other information systems and make it valuable to a wide range of public and private enterprises for explaining events, predicting outcomes, and planning strategies. (ESRI) [4] 5. Results The result of the work is completely in detail scheduled process of integration SAP system with PM system and later with geographical information system (GIS). This description retains the main work in SAP system using ACE Enterprise Integrator technology. Figure 3 : Integration between 2 systems (tables) It includes various specification of SAP functions, tables or communication methods which are SAP GUI, Remote Function Call (RFC), Business Application Programming Interface (BAPI) and communication using Intermediate documents (IDoc). 6
Figure. 2 : Example of communication method BAPI Extremely important is work with tables, because they are base of successful operating with the data. In the entire process it explained, what is where, why, what does it do and what influence does it have on the system. The result is also complete package as background papers for its use in teaching at university. Thereby it is not necessary to ensure the high educated pedagogic but suffice ordinary lecturer or graduand. 7
Figure 4 : Example of using technology Ace Enterprise Integrator Visual Designer 6. Conclusions We have found out that using ACE technology regarding the integration between two systems simplify the whole process of its creating. Nowadays it is really necessary to combine successful companies with schools in order to improve education process and bring so essential practice to the universities. This work can be used on various high schools, universities and colleges as a background papers, in spite of that it is solving just some chosen problems. It is recommended to learn main function of each system and have basic knowledge in integration, what does the term means and how this process works. This work also provides common review about integration systems in the world, their short specification and assimilation. It also monitors the situation on the market and demonstrates us that we are working with top high-quality product used by many companies all over the world. 8
