摘要:
A scheme for automatic data conversion definition generation based on data feature such as a decision tree or a statistical feature, so as to enable a quick data analysis in a visual multidimensional data analysis tool. In an apparatus for converting data stored in database or files into graphic data according to the data conversion definition and displaying the graphic data, a definition generation assistance device for automatically generating the data conversion definition is provided, where the definition generation assistance device extracts a data feature of the data from a scheme and contents of the database or files, and automatically generates the data conversion definition according to the extracted data feature, the data conversion definition being formed by an attribute mapping definition defining combinations of data attributes and graphic data parameters and a data conversion method definition defining a method for converting a value of each data attribute into a value of a corresponding graphic data parameter.

An integrated retrieval scheme retrieves data involved in a plurality of semi-structured documents scattering over open networks and collects the required information item by item from the semi-structured documents through a unified interface without regard to differences in the document structures, presentation styles, and elements of the semi-structured documents. The search scheme receives a query consisting of search items and search conditions from a user. The search scheme finds, according to location data that specifies the location of each of the semi-structured documents, the location of each semi-structured document that contains all search items and converts, if necessary, item presentation styles of the entered query into that of the location found semi-structured documents according to style conversion data, and forms queries for the location found semi-structured documents, and transmits the queries to the found locations and obtains the location found semi-structured documents, and extracts item data from the obtained semi-structured documents according to structure data being used to delimit document into items and attribute data being used for conditional retrieval, and prepares a search result, and converts, if necessary, item presentation styles of the search result into the item presentation styles of each user according to the style conversion data.

In a data write apparatus to a flash electrically erasable programmable read only memory (EEPROM) built in a microcomputer which is mounted on a circuit board, a write control section first initializes the flash EEPROM to allow data to be written in the flash EEPROM, and supplies a signal indicative of the data for the flash EEPROM. A level converting section convertes a level of the data signal such that the data signal level matches to an actual operation voltage level of the flash EEPROM and supplies the converted data signal to the flash EEPROM such that the data is written in the flash EEPROM.

In a microcomputer comprising internal buses, a serial communication interface, a flash memory, a RAM, a ROM for storing a writing program, an input/output port, a CPU, and a mode control unit for setting various operation modes and test modes in the microcomputer, a switching circuit is connected between the ROM and the internal buses and between the input/output port and the internal buses. The mode control unit operates the switching circuit in an emulation test mode so that the ROM is deactivated and the input/output port is activated. Then, the CPU reads a program from the serial communication interface and writes the program into the flash memory in accordance with a writing program from the input/output port.
