data compare

Devart is glad to announce the release of dbForge Data Compare for PostgreSQL — a powerful and easy-to-use tool for table data comparison and synchronization. This tool allows you to review all the differences in compared tables and execute an automatically generated script to remove these differences. Customizable comparison and synchronization process allows you to select tables and fields for comparison and adjust many comparison options. User friendly wizard, guides you through the data comparison and synchronization process step by step. A possibility of using Windows Task Scheduler enables you to automate database synchronization process.

The key features of Data Compare for PostgreSQL include the following:

Flexible customization of database object mapping. Data Compare for PostgreSQL allows you either automatically or manually map schemas, tables, views, columns. You can use custom mapping to map schemas or database objects that can not be mapped automatically.

Comfortable view of data differences. Processing data comparison results is easy and quick, as they are displayed in a convenient way in the Data Comparison document. Database objects can be filtered by the differences.

Full control over data to synchronize. After comparison you can easily exclude tables or individual records from synchronization.

Easy to use Data Synchronization wizard. Data Synchronization wizard enables you to customize synchronization settings. You can backup target database before synchronization. Generated synchronization script can be immediately applied to the target database or saved in a file.

Warnings of possible data loss and various notifications. Before synchronization you will be warned if errors or data loss may occur because of types incompatibility. Also you will be notified about data overflow, roundings, etc.

Large script execution. dbForge Data Compare for PostgreSQL allows you to execute large scripts without opening script in the SQL editor and loading the whole script in memory. When you try to open a large script, you will be prompted to execute it instead with the help of the Execute Script Wizard.

Compare and sync data via command line. You can compare and synchronize data via command line. There is no need to open the application and go through the wizard pages any more.

Friendly GUI. Data Compare for PostgreSQL provides a self-intuitive user interface, so you will quickly learn how to use the product to your advantage.

Enhanced working with data. You will get new opportunities for analyzing and processing received data the best way:

• Group, filter, and sort data in the grid
• View data rows as neat cards
• Display data in the paginal mode
• Find the required data using the auto-search mode

Recently we were working over the release of the version 2.0 of  dbForge Data Compare for Oracle. One of the main features added to the new version was synchronization of the LOB data. When we developed the first release of the product we postponed this feature because of challenges of synchronizing LOB data. These challenges caused by nature of data stored in BLOB or CLOB columns. It’s large and simply does not fit into SQL script. But we’ve found the solution.

In this article we will examine basic methods of loading LOB data into a table.

During replicating data in one or another way, it happens that synchronized objects may differ. This situation may take place in the following cases:

• If changes made in one of copied databases were not captured
• The changes were captured but not forwarded
• The changed were forwarded but not applied due to some reasons

It should be admitted that full or partial synchronization may be required due to some other reasons, not related to replication. But the question is how to synchronize database objects?

In the process of developing databases many developers and testers encounter a problem of synchronizing data between local and remote Oracle database. Changes made in a local database must be reflected in a remote database. It’s also necessary to check test results with the model database, to find non-synchronized tables that appeared after these tests, to have possibility to return the test database to its initial state when testing newly developed versions of databases intensively. Another problem may be to create CRUD operations quickly without making too much effort to find different objects and to write DML statements. Now let’s find out how one can synchronize data of Oracle databases.

Simple solutions:

Devart today unveiled a new data comparison tool, dbForge Data Compare for Oracle. It delivers automatic data comparison in Oracle databases, provides a convenient GUI to manage the differences, and generates SQL*Plus-compatible synchronization script to synchronize the data.

Not a long time ago we started to write auto-tests for testing our new product –
dbForge Data Compare for Oracle. To recreate a schema in Oracle all user sessions should be killed.

To achieve this we’ve written the following PL/SQL script:

Recently our development efforts were focused on dbForge for SQL Server product line. We’ve made five major releases of SQL Server database tools in last 18 months. Besides, we’ve made two major releases of MySQL database tools in this period. Our Oracle database tools product line, once actively developed, was frozen for almost three years. Sure we made maintenance releases, but no new features and tools. Our Oracle tools even were not re-branded to dbForge for Oracle. But now we decided to breeze the new life into Oracle tools development.

The first tool in the dbForge for Oracle product line will be Data Compare. For the first release we decided to make a free tool with basic functionality:

We compared some best-of-breed data comparison tools with dbForge Data Compare 2.00 to find out which one is speedier to compare and synchronize data in SQL Server databases.

The participant tools were tested with default settings on live databases on SQL Server 2008 that installed with default settings on a desktop (with a dual-core processor and 2Gb of RAM). Both the SQL Server and the tools were installed on the same desktop.

Live Databases:
Two databases with total size of 1Gb: 115 tables containing one with 3 million records of numeric and string data types, the other with middle size BLOB data.

Task №1: We measured the speed of each tool while comparing the data, generating an update script, and at last synchronizing the databases.

Data Comparison/Synchronization Performance

Result №1: Tests results show that dbForge Data Compare for SQL Server v2.00 has leaved the competitors far behind.

Task №2: We decided to compare the performance of the selected participant tools based on the main industry-leading competitor’ performance. Besides we took into account the product price and tried to calculate the efficiency as best performance for less money.

Performance/Price

Result №2: This graph shows that not all the tools can be proud of delivering an expected combination of best performance and best price. dbForge Data Compare handles this task well.

Check Shot

To fully complete our research, we decided to go the whole hog and use the aforementioned tools to compare large databases with the size of 120Gb (some tables in these databases have 2.4 billion records, some tables contain 1.5Gb of LOB data, the FILESTREAM table is with 5.3Gb of records). dbForge Data Compare was good at comparison, while neither of the competitive tools compared tables with LOB data and records in the FILESTREAM table. When we excluded such tables, only one tool coped with 2.4 billion records.
Speed rate of dbForge Data Compare is several times higher than other popular competitive tools have.

Try dbForge Data Compare on your database. Delivering qualitative data comparison and synchronization is our fame.

We guarantee quick support and product improvement if dbForge Data Compare fails to compare and synchronize your database. We even may give you the product license for free.

Devart announced the release of a new version of the professional tool for SQL server data comparison and synchronization – dbForge Data Compare 2.00. Committed to support the needs of database-dealing professionals, Devart now delivers a performance-leading SQL comparison tool that incorporates three times faster data comparison and synchronization, the smallest price and greater satisfaction than all other data comparison tools offer.

Incorporating these three components, dbForge Data Compare 2.00 guarantees greater satisfaction and smother database-dealing experience for any SQL comparison and synchronization goals.

The highlights of dbForge Data Compare 2.00 include:
