SQLData is a scalable, high performance data transfer, schema conversion and validation tool for Oracle to Microsoft SQL Server and SQL Azure migration.The tool allows you to move and validate the migration of large volumes of data and database schema within the shortest possible time frame.
SQLData benefits:Transferring tables in multiple concurrent sessions,performing concurrent read and write operations in each session,using Oracle OCI with array processing to extract data from Oracle, and using SQL Server Native Client Bulk Copy API to insert data to SQL Server.It is designed for DBAs and Enterprise-Class Migrations
SQL Server Migration Assistant (SSMA) for Oracle is a comprehensive environment that helps you quickly migrate Oracle databases to SQL Server, Azure SQL Database, or Azure Synapse Analytics. By using SSMA for Oracle, you can review database objects and data, assess databases for migration, migrate database objects to SQL Server, Azure SQL Database, or Azure Synapse Analytics, and then migrate data to SQL Server, Azure SQL Database, or Azure Synapse Analytics. Note that you cannot migrate SYS and SYSTEM Oracle schemas.
Oracle Data Integrator (ODI) seamlessly integrates data in Microsoft SQL Server. Oracle Data Integrator features are designed to work best with Microsoft SQL Server, including reverse-engineering, changed data capture, data integrity check, and mappings.
The Microsoft SQL Server concepts map the Oracle Data Integrator concepts as follows: A Microsoft SQL Server server corresponds to a data server in Oracle Data Integrator. Within this server, a database/owner pair maps to an Oracle Data Integrator physical schema. A set of related objects within one database corresponds to a data model, and each table, view or synonym will appear as an ODI datastore, with its attributes, columns and constraints.
Oracle Data Integrator uses Java Database Connectivity (JDBC) to connect to Microsoft SQL Server.
In the relational database management system (RDBMS) software space, two giants stand out from the rest, offering more features and user benefits: Oracle Database and Microsoft SQL Server.
However, it can be difficult to choose between the two leading RDBMS products. See below to learn how the two systems compare and guide your selection process:
A database management system (DBMS) is software that helps enterprises to organize and manage both structured and unstructured data across company databases.
Both Oracle Database and Microsoft SQL Server function as relational database management systems (RDBMS), or systems that help you to manage the relationships across data via tables.
Oracle describes a database management system as software that interfaces between databases and end users or programs, making it possible to work with data through performance monitoring, tuning, backup and recovery, management, and overall optimization.
Microsoft and Oracle are pretty neck and neck when it comes to most of their features but that hasn’t always been the case. Oracle has traditionally offered stronger querying features, but with the introduction of SQL Server 2019 and its Big Data Clusters, Microsoft is matching the pace of Oracle’s tools like Real Application Clusters (RAC).
There are still some areas where Microsoft falls behind, such as transaction control features. Transaction controls make it possible for a user to separate the different operations that happen in a transaction. If something goes wrong in the transaction, the user can identify where it happened, and they don’t have to roll back the entire transaction.
Transaction controls have been a feature of Oracle Database over the last several versions, separating each operation into individual transactions to increase visibility and avoid errors. In Microsoft SQL Server, each operation happens sequentially within a given transaction, so it’s challenging to check for and eliminate pinpointed errors within a transaction of data.
Again, the latest version of SQL Server matches many of the strengths that Oracle has shown off for years, but with features like transaction controls and a larger portfolio of in-house data tools, Oracle Database takes the feature category.
