Using AWS Schema Conversion Tool for Application Conversion

Posted by | On February 24th, 2017 | In AWS, Database Migration | Tags: , , , , ,

A typical database migration project includes not only the schema conversion and data migration but also the application remediation. We are talking about one or many applications interacting with the source database. To wrap up the database migration project, you will need to convert the SQL code used in the application and then reconnect it to the new database. AWS Schema Conversion Tool (SCT) helps to automate this process and simplifies required efforts estimation for manual SQL code conversion.

Check the following video to see the application conversion project in use and find out how the AWS Schema Conversion Tool helped our DBAs during migration projects.

Make sure to check out our new AWS Schema Conversion Tool Jumpstart offer to get you up and running fast for your migration to Amazon Redshift.

Portfolio spotlight: Momdezvous mobile application

Posted by | On February 5th, 2017 | In Customer Story, Mobile Development | Tags: ,

Mothers of small children are a specific category of people, united by common interests, problems, and hobbies. Absolutely all mothers are interested in finding new friends for communication, spending time together, and visiting various events. It would be great if new friends were living nearby. The main goal of the Momdezvous mobile application, developed at DB Best, is to unite moms with small children on one social network and provide interesting leisure and activities. Momdezvous is a private social network (like Facebook), intended for a narrow audience. It allows users to meet other users to build friendships for themselves and their children.

In the following video review, we’ll discuss the technical features of this project.

Cross platform video streaming using RTSP

Posted by | On January 27th, 2017 | In Mobile Development | Tags: , , , , ,

Remote cameras can be used in various application solutions. Usually, this technology helps with building a local monitoring system for home or office (for example, a baby monitoring system). Besides that, remote cameras can come in handy for the fun and games industry: you can attach the compatible device to drones or other radio controlled toys and control them using a live view from the remote camera.

Drone RTSP2


The live video broadcast from one mobile device to another can be carried out in different ways. For example, you can use the common Real Time Streaming Protocol (RTSP). It supports direct video broadcast and doesn’t require an intermediate server. In fact, the streaming device automatically becomes the server.

We used the RTSP to build an application prototype, which allows watching live video from the smartphone’s camera on the screen of a connected device. This application works in 2 modes: a server and a client. In the first one, the smartphone becomes a server broadcasting the video. And in the second mode, the application acts as a client receiving the video from the server and displaying it on the screen.

Watch the following video to learn more about the RTSP application, developed by DB Best.

Introducing Fast Data Comparison in Database Compare Suite version 4.6

Posted by | On January 27th, 2017 | In Database Migration, Database Upgrades | Tags: , ,

Many of us regularly use Database Compare Suite — a tool developed by DB Best — for database migration and upgrade projects. This powerful and handy software solution helps confirm successful database migrations by verifying that the data made it to the destination table.

Customers reported to us that comparing data between two huge tables simply took too long just to see if they were different. We listened and did something about it. This latest version of Database Compare Suite introduces a new feature called Fast Data Comparison to solve this problem.

Database Compare Suite 4.6 Release

Data Comparison

Data comparison has always been the core of the Database Compare Suite product. Originally, we included two data comparison operations in this application:

  • Comparing Data. A basic operation that displays the number of differences in two tables but does not show where they exactly are.
  • Comparing Data in Detail. Advanced operation that can show exactly which rows are different.

But they both were not suitable for faster comparison of big data sets in data warehouses.

So, we are proud to introduce the newest Fast Data Comparison feature capable of comparing the tables with millions of rows in just minutes, not hours or days.

Check the following video to learn more about how the Fast Data Comparison operation works.

First look at AWS Schema Conversion Tool with tighter DMS integration

Posted by | On January 3rd, 2017 | In AWS, Database Migration | Tags: , , , , ,

On December 20 2016, Amazon released version 1.0.502 of AWS Schema Conversion Tool (SCT). SCT now provides the integration with Data Migration Service (DMS)  and allows you to create AWS DMS endpoints and tasks. In addition SCT allows you to run and monitor the DMS tasks from SCT.


AWS Database Migration Service helps you migrate databases to AWS easily and securely. The AWS Database Migration Service can migrate your data to and from most widely used commercial and open-source databases. The service supports homogenous migrations such as Oracle to Oracle, as well as heterogeneous migrations between different database platforms, such as Oracle to Amazon Aurora or Microsoft SQL Server to MySQL.

As part of DMS integration, SCT introduced support for AWS profiles where users can store credentials for Amazon S3, AWS Lambda and DMS using the AWS Schema Conversion Tool interface. Finally, SCT now supports Amazon Aurora with PostgreSQL as a target database for conversion and migration projects.
