What is a Microservices Architecture? Microservices architecture is a style that structures an app as a set of predetermined services. At its core, such app is split into smaller independent segments that perform their own functions. This approach permits to view microservices as a group of undivided apps that handle their own features. As a result, we get an app that can perform a variety of functions by employing appropriate services. Pros & Cons of Microservices Approach Just like any […]

What is monolithic architecture? Monolithic architecture is known as a traditional approach to software development that is based on a single-unit design. This means that a program is basically a self-contained and independent unit. It consists of a database, client-side user interface, and server-side application. As it is possible to clearly see, a monolithic app is a single logical executable that usually does not interact with other services.   Pros & cons of monolithic approach Let us take a closer […]

In this post we continue exploring the technical aspects of Oracle to PostgreSQL migration using AWS SCT. AWS SCT promises a very high level of migration efforts, however it is very rare that 100% automation is achieved. In this article we’ll look into conversion of INSERT ALL statements, which are quite popular in Oracle code. We were using AWS SCT build #660 to convert one of our Oracle test databases. Oracle gives you an option to use the conditional insert […]

In this post we explore the technical aspects of Oracle to PostgreSQL migration using AWS SCT. We’ll look into conversion of Oracle “aliases”. We were using AWS SCT build #660 to convert one of our Oracle test databases. The challenge Oracle’s subtype declaration allows creating an “alias” for some datatype declaration, which can be re-used later as many times as needed. PostgreSQL domains entirely differ from Oracle’s subtypes. Thus, whenever you try to convert PL/SQL code containing variables that are […]

Proprietary database features often create significant obstacles for developers. To demonstrate as an example, we will take a look at one of Oracle’s most valuable proprietary features – Oracle Call Interface (OCI). It ensures efficient communication between the database and the application code. Surely, you may use other options for connecting to Oracle. However, once you have committed to OCI, switching to another interface becomes a real headache. Read our new blog post to understand how you can overcome challenges […]

One of our clients contacted ABCloudz to request help with their SQL Server app’s performance issues. They upgraded from SQL Server 2008 R2 to SQL Server 2019 and began experiencing problems shortly after. We analyzed their database system and discovered a complex issue with updating SQL Server statistics. These stats are used by the Query Optimizer to create an execution plan for each query. The problem was that the time to update statistics was taking much longer than the planned […]
