EXP/IMP data migration recently, all data of a user in a small database needs to be migrated to another one. Now, we first simulate that the data volume is not large, use exp to export all data objects of the User: [SQL] [lubinsu @ localhost orcl] $ exp lubinsu/lubinsu @ orcl_03 file =/home/lubinsu/orcl/lubinsu. dmp log =/home/lubinsu/orcl/lubinsu. log owner = lubinsu compress = n Connected to: Oracle Database 10g Enterprise Edition Release 10.2.0.1.0-Production With the Partitioning, OLAP and D

Bitmap indexes are best used for low to medium cluster (cardinality) columns on which multiple bitmap indexes can be used in conjunction with and OR operators. Bitmap indexes use bitmaps as key values, and each data row bitmap in a table contains True (1), FALSE (0), or null values. Bitmap indexes are stored in the page nodes of the b-tree structure.

Use of synonyms1) Simplifying SQL statementsIf the user creates a table with a long name, you can create an Oracle synonym for the table to simplify the statement.2) Hide the name and owner of the objectIn multi-user collaborative development, the names and holders of objects can be masked. If you do not have

], K2 = K5, but h (K2) = H (K5), so the storage address of K2 and K5 is the same. (2) conditions for preventing security conflictsThe best way to resolve conflicts is to avoid conflicts. To achieve this, two conditions must be met:① One is | u | ≤ m② The second is to select an appropriate hash function.This only applies to scenarios where | u | is small and the keywords are known in advance. At this time, the hashed function H is carefully designed to completely avoid conflicts. (3) conflicts ca

. When several small databases are integrated into a large database and serve a wide range of organizations, if the database stores historical data, it provides decision-making support, data aggregation, and read-only data, in essence, it acts as a data receiver for all the finished databases that provide data to it. Therefore, it is usually called a data warehouse. Instance) It is a part of the computer memory required to access the Oracle database and assists in processing background processes

Google provides synonym search results to try natural language understanding Technology Google's official blog today claims that it has used natural language understanding technology to identify synonyms in search. For example, Google search considers "pictures" and "Photos" to be the same in a certain context, taking the Query [pictures developed with coffee] as an example, we can see that the "Photos" in the search results has been bold. This is a
