Ispirer Ecosystem for automated migration

Ispirer Toolkit is a solution for automated heterogeneous database migration. Using it, you can transfer tables and data, stored procedures, functions, packages, views, and triggers. This solution is based on an intelligent proprietary algorithm that analyzes data types, relationships between objects, reserved words, and code structures that do not have equivalents in a target technology.

Migration details overview

Ispirer Toolkit automates

Ispirer Toolkit automates the entire migration of database objects from Oracle PL/SQL to Microsoft SQL Server

Both conversion with connection to the source database, and conversion of files containing Oracle PL/SQL scripts are possible. The first option is most recommended, as the tool will get all the required information about object dependences directly from the database. Ispirer Toolkit can migrate the following objects: tables, views, functions, procedures, packages (specification and body), triggers and sequences, collection and object types. Each separate database object is converted to its equivalent in Transact-SQL.

If you have your own applications, the Embedded SQL and Database APIs can be converted using either Ispirer Toolkit or Ispirer Service. They will be able to work with your new Microsoft SQL Server database.
Table and Data Conversion

Ispirer Toolkit converts tables with all related objects

Indexes, referential integrity constraints and data to the target Microsoft SQL Server database. All Oracle native data types are converted to the SQL Server equivalents.

If necessary, the user can change the default settings of data type mapping.
Procedure, Function and Trigger Conversion

Transact-SQL

Oracle user procedures, functions and triggers are converted to stored procedures, functions and triggers written in Transact-SQL (T-SQL) syntax, depending on the version of the target database. Packages are converted to a separate set of objects - procedures and functions in T-SQL.

Package-level variables and constants are taken into account

They are migrated to tables where actual values are stored. Moreover, an additional set of user-defined functions (UDFs) will be automatically generated. They will work only with such tables.

These UDFs will be able to set and update values in such tables T-SQL built-in functions and procedures are converted to their equivalents in SQL Server

If there is none, the tool will try to convert the functions to T-SQL expressions. They will emulate the same behavior or generate a user-defined function that will work the same way as in the Oracle database.
Working with Collections and their Methods

Ispirer Toolkit supports collection conversion of all three types: Associative array, Nested table, Variable-size array (varray)

They are converted to a SQL Server table. Then a set of user-defined functions is generated. This allows to work with values in such tables.
Oracle Supplied PL/SQL Package Conversion

Ispirer Toolkit supports conversion of some Supplied PL/SQL Packages, such as UTL_FILE, DBMS_LOB and others

The list can be expanded depending on the requirements of your conversion project.

Automated conversion of SQL objects to application code. Ispirer Ecosystem supports Oracle, SQL Server, Sybase, PostgreSQL, Java, C#, Python, etc.
In case of changing the RDBMS, embedded SQL will be automatically rewritten to adhere to the syntax of the new database.
Migration with or without connection to databases. Both options allow you to successfully migrate business logic from the database to the application layer. However, connecting to the database allows the migration tool to take into account additional data from the database and helps improve the conversion.

Migration with\without connection to databases.

/ If RDBMS changes, EmbeddedSQL will be automatically rewritten to adhere to the new database syntax
/ Ispirer Toolkit supports Oracle, SQL Server, Sybase, PostgreSQL, Java, C#, Python, etc.
