Our client is a large pharmaceutical company with a sophisticated data infrastructure. Along with the company’s rapid growth, its data infrastructure started growing as well. At one point, their data infrastructure exceeded 140 SQL Servers united by multiple scripts and connections. This growth made its maintenance more challenging and time-consuming. The customer created a professional support and monitoring team to handle any data infrastructure issues, but this did not solve the entire problem. The customer still had issues with organizing […]

One of our customers runs a large Azure data center that works with Personal Health Information ( PHI). Before the client contacted us, many of their servers have been running on legacy OS and the overall infrastructure was rather disorganized. The Company’s management was concerned about potential security holes and requested to conduct a thorough security audit. Before contacting ABCloudz, the Company’s IT staff had been aware of potential security gaps in their infrastructure. For example, their data infrastructure included […]

Our client is a healthcare testing and biotechnology company that quickly grew from a small antigen development lab into a large producer of various healthcare tests distributed across the U.S. The client developed a new custom device for some of the most rapid COVID-19 tests. It includes a pipette for collecting blood and a small test cassette in which the tested blood should be placed. 15 minutes after placing the patient’s blood into the cassette, rose or red stripes become […]

Recently, the ABCloudz team migrated a customer’s database from Apache Cassandra to Amazon DynamoDB. As part of this project, we needed to run multiple tests to ensure perfect quality for our delivery. However, we faced a problem in setting up the test environment. Even though we were using AWS CloudFormation templates for the EC2 instances, it was taking over 30 mins to get the dev/test environment setup. In addition, our developers couldn’t run parallel regression testing. So, we decided to leverage Docker to automate the environment set up.
In this blog post, we will share our experience with using Docker for automating a NoSQL database migration dev/test environment.

One of the world’s largest distributors of non-food consumable products wanted to rationalize their data platform and business intelligence strategy. Their current IBM DB2 database system lacked a repository to host historical audit-related data, so they could hardly retrieve data from past years. Then we came up with an Azure cloud database solution that could store all the historical data and created Power BI reports on top of it. We performed the IBM DB2 Azure SQL Database migration as a […]

HIPAA (Health Insurance Portability and Accountability Act) is one of the most important United States federal statutes which has a great impact on the development of medical software. This act stands for the safety of the protected health information (PHI) and defines security standards that each digitized medical business should follow. HIPAA sets numerous requirements for data security management. Enabling these rules is not easy and sometimes creates much complexity during the development process. Our client, a medical business developing […]

It’s no secret that a modern world runs on data. This essential asset is stored in databases or data stores. And keeping such databases or data stores healthy is vital in the digital era we live in. It is also no secret that database issues can take down entire systems and cost businesses many thousands of dollars per hour. The ABCloudz team has years of experience supporting customer databases and delivering database services. A couple of our customers recently requested […]

One of the largest educational organizations in the United States had been running their data handling system in the Oracle environment. They wanted to reduce maintenance costs due to the expensive Oracle licensing model, which includes an additional fee for the partitioning feature. The ABCloudz team provided a solution for migrating the customer’s database to SQL Server. Reconstruction of the original partitioning system in SQL Server allowed us to significantly lower SQL Server maintenance costs compared to Oracle. Check out […]

One of our clients, a large financial software company, wanted to migrate their billing solution from Oracle to SQL Server. They needed to initiate this project because the migration was required by one of their strategic partners. The customer decided to implement SQL Server Integration Services (SSIS) for this migration. Additionally, they needed to do the data transfer from Oracle to SQL Server. Because of the complexity of the project, the client sought software developers that would build an automated […]

One of our clients, prominent information technology company, needed to migrate its Oracle database to SQL Server so they called ABCloudz. They knew they wanted to automate the major part of the migration with SQL Server Migration Assistant (SSMA) but there were some challenges associated with this process. First, the company’s source database code contained over 400 hierarchical queries that could not be converted with SSMA. And second, the company’s technical staff was also unable to convert such queries. By […]

The migration of Oracle databases to Microsoft SQL Server brings many challenges. One of the most significant is associated with mapping Oracle schema to SQL Server. At the architecture level, the wrong approach will result in significant effort in the future. For example, you may even need to rewrite your app’s entire code from scratch. The problem Oracle database server includes an Oracle database and an Oracle instance. You may learn more about the architecture of the Oracle server here. […]

Mapping Oracle data types to SQL Server data types is often a problem during Oracle to Microsoft SQL Server database code conversions. A tried and trusted solution is to use an SQL Server database code conversion. Another reliable solution is to use SQL Server Migration Assistant. These solutions enable you to automate Oracle database conversions to SQL Server. However, there might be some issues you should consider while using SSMA. For example, by default, SSMA applies the maximum available size […]

A materialized view is an important property of Oracle. SQL Server recreates the same behavior as this materialized view in several ways. Unfortunately, SSMA may have issues with converting this object to SQL Server. It flags certain conditions as an error. In this blog post, we will overview the error O2SS0522. It goes about cases in which the Oracle materialized view includes FLOAT columns, subqueries, GROUP BY or WHERE clauses, MINUS, INTERSECT, UNION, etc. By default, SQL Server Migration Assistant (SSMA) converts Oracle […]

ABCloudz tech experts possess outstanding experience in migrating databases. For this purpose, we frequently use SQL Server Migration Assistant (SSMA). SSMA utilization may cause various types of errors, so we have created a blog post series which focused on typical database conversion errors. Each post in this series is dedicated to a separate problem statement and presents our recommendations on how it should be approached and fixed. Related posts Here is the list of blog posts on the most common SSMA […]

Oracle enables you to use specific interval literals for indicating a certain period of time. Unfortunately, there is no direct analog for such literals in SQL Server. As a result, when you apply SQL Server Migration Assistant (SSMA) for converting Oracle code with interval literals, you receive an error O2SS0086. The term ‘interval literals’ refers to a fixed data value, such as the constant value term. Interval literals can be specified in terms of seconds, minutes, hours, days, months, or even years. There are two […]
