俄国人写的内存数据库的delphi封装

FastDB Main Memory DBMS system version 2.61.

----------------------------------------------------------------------------------------
Installation under Delphi/Kylix
===============================
1. Open Delphi/Kylix IDE
2. Open FastDBd6.dpk project (File/Open Project)
3. In the project viewer (View/Project Manager) click "Compile", and then "Install".  The VCL library will be installed on the component panel under "Data Access" tab.  Two components will be registered: TFastDbSession and TFastDbQuery.

----------------------------------------------------------------------------------------
Known issues
============
1.  TFastDbSession
		  The following sequence of calls corrupts table field descriptor of SomeTableName1:
		  CreateTable("SomeTableName1", ...)
		  DescribeTable("SomeTableName1")
		  CreateTable("SomeTableName2", )
		  DescribeTable("SomeTableName1")

    Workaround: Don't call DescribeTable between CreateTable() calls 

2.  In large multi-threaded projects using LocalCLI interface if concurrently some 
    threads do inserts and others do deletes of records in the database, this may 
    lead to an Access Violation.  This problem was consistently observed in a large 
    database (512M).  It has not been a problem with single-threaded applications.

    Workaround: Modify application not to use record deletions in the database in a 
                multi-threaded content.
