Modularized extraction, transformation, and loading for a database

Techniques exporting data and metadata from a source database environment to a target database environment are provided. The techniques include the steps of analyzing metadata that describes one or more items, the data for which is in a source database, where the one or more items include at least one of a view, a sequence, a dimension, a cube, an ETL mapping, and any database object for which the metadata is stored outside of the source and target databases. The data for each item resides in a data file associated with the source database. The data for each item is incorporated into the target database based on the metadata by providing the target database access to an incorporated data file, where the incorporated data file is the data file or a copy thereof. Techniques are also provided for exporting database data from the source database. The techniques include extracting metadata that describes one or more items, the data for which is in the source database, where the one or more items include at least one of the structures described above. The data for each item resides in a data file associated with the source database. After the exporting, a database server that manages the target database is provided access to an incorporated data file, where the incorporated data file is the data file or a copy thereof.

Realization method of image searching system based on image recognition

The invention discloses a realization method of an image searching system based on image recognition; wherein the realization method comprises the following steps: carrying out preprocessing steps such as format transformation on images in adding images; carrying out recursion multilevel cutting to obtain all potential characters, portraits, objects and object subimage blocks based on uniform space, contrast grade, similarity in color and texture; obtaining marking texts of position and color; carrying out texture and material recognition, character recognition, outline object recognition and text marking on the subimage blocks; carrying out combination and word segmentation on the marking results; establishing index for the word segmentation result and related subimage block information and storing related data of the subimage blocks; in the situation of searching based on images, first identifying images and marking texts; then carrying out word segmentation on the text to obtain index data of a keyword sequence; combining and sequencing the index data of the keyword sequence to obtain related data of the subimage blocks and the images matching with the result set, and returning to users. With the system and method of the invention, the users can input characters and images to retrieve the content of the images.

Method for obtaining resident travel characteristic parameter based on mobile phone positioning data

The invention discloses a method for obtaining a resident travel characteristic parameter based on mobile phone positioning data. The method comprises the following steps of: (1) collecting mobile phone positioning data; (2) filtering the mobile phone positioning data, matching the mobile phone positioning data to traffic zones, and obtaining the matched mobile phone positioning data; (3) using users as units, ordering the matched mobile phone positioning data in one day by time, merging the continuous data in the same one traffic zone into one piece, and obtaining mobile phone positioning pretreatment data; (4) according to the number of emerged pieces and influence duration, judging residing points, restoring a travel path between two residing points, and obtaining the travel distance and the travel speed, and then obtaining a travel log table of all users; (5) on the basis of the matched mobile phone positioning data, statistically obtaining a place of residence and workplace result table; and (6) and conjointly analyzing the travel log table and the place of residence and workplace result table, and obtaining resident travel characteristic parameters. The method has the characteristics of low cost, large sample quantity, high precision and high time validity.
