Migrate MySQL to Microsoft SQL Server 2000 (2)-database-PHP Tutorial

MySQL tool for data migration
MySQL provides several client tools and utilities. The most common ones are: mysql-an interactive client program, you can publish a query to the database and view the results mysqldump-This tool can extract the architecture and data in the MySQL database and put it into a file mysqlimport-This tool can read the architecture and data in the file, and put it in a MySQL database mysqladmin-This tool can execute management tasks, such as creating a database and deleting a database myODBC-a 32-bit open database connection software, provides ODBC-level 0 (with level 1 and Level 2 features) drivers for connecting ODBC-recognized applications to the migration tool of MySQL SQL Server
SQL Server has a rich set of tools and utilities to simplify migration from MySQL. SQL Server 2000 data conversion service (DTS) is a set of graphical tools and programmable objects used to extract, convert, and merge data from various sources to one or more targets.
Functions of data conversion service
The data conversion service in Microsoft SQL Server 2000 allows you to migrate data from different data sources. Data transmission can be driven by a wizard or a data transmission package designer. The DTS Wizard allows you to quickly copy data directly. The package designer allows developers to write custom conversion scripts in multiple programming languages. DTS allows you to migrate data from MySQL to SQL Server 2000. The data migration table and data type are displayed before migration, for example, you can use the MySQL data table to migrate the text and date to the MySQL database to generate and view the migration report. Custom data tables and default data type ing rules are used to resolve conflicts, for example, the SQL Server reserved word conflict is deleted, and the object migration in the SQL Server architecture model is renamed.
The following are the terms used to describe DTS:
A data transmission package is an organized set of connection, data transmission task, data transmission conversion, and workflow constraints. It can be compiled in the data transmission designer graphically or programmatically.
A data transmission task is a set of discrete functions and is executed in a single step in the package. Each task defines a work item to be executed during data movement and data conversion, or a job to be executed.
DTS conversion refers to one or more functions or operations to be applied to the data before it reaches its destination.
The DTS package workflow allows the data conversion service (DTS) to run gradually, and the work items in the DTS package are sorted by the priority constraint. You can design the DTS data packet workflow graphically in the DTS designer or by programming.
Metadata provides the function of DTS to save the package metadata and data lineage information to the metadata service and link those information types. You can store the category metadata of the database referenced in the package and collect historical information related to specific data rows in the data mart or data warehouse.
