Oracle database based data recovery method

The present invention discloses an Oracle database based data recovery method comprising the following steps: S1: determining a data table of a database; S2: obtaining all the information of the table; S3: obtaining a recorded logical structural relationship; S4: obtaining specific information of fields; S5: obtaining logical structural features of data recovery ; and S6: composing data into the form of the the data table, and extracting the data. The present invention has the following beneficial effects: the records and fields in the data table are parsed by virtue of an Oracle database structure, the head of each record and the structure division data of the fields are found and then are extracted, the data recovery efficiency is high, the data destruction and the data discontinuous fragment level database can also be normally extracted and recovered, the data recovery success rate is high, and the loss caused by database damages is effectively reduced.
