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.

SQL Server to Oracle migration details overview

  • Ispirer Toolkit automates

    Ispirer Toolkit automates icon

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

    Both conversion with connection to the source database, as well as conversion of files containing Transact-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 and data, views, functions, procedures, triggers, sequences and user-defined types. As a result, each separate database object is converted to its equivalent in Oracle.

    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 Oracle database.

  • Table and Data Conversion

    Table and Data Conversion icon

    Ispirer Toolkit converts tables with all related objects

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

    If necessary, the user can change the default settings of data type mapping.

  • Procedure, Function and Trigger Conversion

    SQL objects icon

    SQL objects

    Transact-SQL user procedures, functions and triggers are converted to stored procedures, functions and triggers written in PL/SQL syntax, depending on the version of the target database.

  • Built-in Functions and Procedures Conversion

    Built-in Functions and Procedures icon

    Transact-SQL built-in functions and procedures are converted to their equivalents in PL/SQL

    If there is none, the tool will try to convert the functions to PL/SQL expressions. They will emulate the same behavior or generate a user-defined function that will work the same way as in the SQL Server database.

  • Working with User-Defined Types

    User-Defined Types icon

    Ispirer Toolkit supports conversion of user-defined type to its equivalent in the Oracle database

    According to the type and its usage, it may be converted to a user, native type, or to a Oracle table. Then a set of user-defined functions is generated. This allows to work with values in such tables.

Move your migration project to the next level. Migrate logic from database to application

Ispirer has a solution to unlock the full potential of your database. Our team helps you to move business logic to an application layer seamlessly to advance the database performance.

Seamless integration, limitless possibilities!

Application target Code

  • Java
  • JDBC
  • Spring
  • Hibernate
  • Automated conversion of SQL objects to application code. Ispirer Ecosystem supports Oracle, SQL Server, Sybase, PostgreSQL, Java, 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.
  • Unlock agility: shift your database logic to the application layer!

    Transform faster, scale smarter—see how moving from database to application layer drives real results. Let’s modernize it together.
