are loaded in the SOT² or other CRM tools. Shibui-ITs fits in any on-premise server or cloud platform, and
uses virtual machines, state-of-the-art soſtware logic, network infrastructure and storage solutions from leading companies. Its architecture is scaleable, designed to interface with all existing customer systems and data sources.
OLTP data modelling Compiling the requirements of the Shibui-IT target application and developing a logical data model is the key to a reliable and robust physical Shibui-IT OLTP design; see Figure 3. Te transactional PoC OLTP has four layers: 1. Current CSV files: Master data imported from the SAC CSV databank;
2. Corporate memory: Contains the complete history of loaded master data;
3. Reporting foundation: n number of master data tables needed for the BI; and
4. OLTP processing, modification and calculation ETL logic, which prepares the operational data from the ‘current CSV files’ for the corporate memory and, subsequently, for the ‘reporting foundation’. The OLTP selects the needed data from the SAC, applies
ETL processing logic to it and moves the operational data into the Shibui-IT OLAP Cube; see Figure 4. The Cube is the data structure of the Shibui-IT’s SQL server analysis services (SSAS), which uses the OLAP databases to analyse the data sources. The source of the OLAP data base is the operational data from the OLTP Reporting Foundation. In effect, the Cube is created by an OLAP pivot feature
which aggregates all the data. Te Cube’s columns and rows are determined by defined dimension keys, and its cells contain all master data measured values from the company. In the OLAP multidimensional data model, there is a set of
numeric values that are the objects of the OLAP processing, consisting of bookings, billings, revenue performance, design opportunities, design wins or forecasts, and more. Each of these values depends on a set of dimensions, which provide the context for the measurement. Te OLAP design is based on three fact tables – sales orders,
plans and opportunities – which are linked to an n number of dimension- and sub-dimension tables, all of which are represented in the n-dimensional OLAP data cube.
Data visualisation and web delivery Te BI front-end design tool has an XLCubed Excel add-in soſtware suite that connects directly to the OLAP database, manages the report definitions and creates a dashboard with a set of pre-defined reporting templates, spanning from basic billing and booking reports to revenue analyses. Tere are added special Shibui-IT reports, like Vantage Charts and Customer Fact Sheets, part of the BI applications library; see Figure 5. And, with the ShibuiWeb (XLCubedWeb) – a Microsoſt Internet Information Services, any report, chart or factsheet created by the BI tool can be safely published with a few clicks and rendered in all common web browsers. All Shibui-IT applications are standardised yet role-specific,
i.e. top-level managers get the information they need to run the company successfully, whilst account managers get access to reports needed to better serve the customers.
