What is DevOps?

Database DevOps is a philosophy that comprises the following concepts:

  • automating the development, deployment, documentation, testing, and monitoring processes between software developers and operations engineers
  • integrating the development and operations processes to efficiently synchronize, validate, manage, and apply database changes

The Database DevOps practice is focused on improving the efficiency of database management. It helps with streamlining the process of deploying and improving databases by giving the ability to automate many aspects of the database lifecycle, thus speeding them up and simplifying them.

Therefore, DevOps is the best practice to unify development, operations, and quality assurance processes. Read More

Automated testing of the desktop application: expediency and frameworks overview

Introduction

You have certainly heard about regression and acceptance testing. But do you know how much is actually spent on acceptance testing in a project?
We can quickly get an answer to this with the help of a time tracking system like TMetric.
On our project, acceptance-testing a desktop application of around 100 assemblies took more than 2 person-weeks. New QA specialists who didn’t know the application well were having the greatest difficulties. Compared to more experienced QA specialists, they spent much more time on each test case.
However, in my opinion, the most unpleasant part was this – if any critical errors are found before the release, acceptance testing must be performed again after these errors are fixed.
Written unit tests helped a little bit, but they still mostly reduced the time spent on regression testing. With this, when the amount of manual testing reached a critical level, we started moving towards automation. Read More

Database Normalization: A Primer

The Relational Model of data management was first developed by Dr. Edgar F. Codd in 1969. Modern relational database management systems (RDBMSes) are aligned with the paradigm. The key structure identified with RDBMS is the logical structure called a “table”. Tables are primarily composed of rows and columns (also called records and attributes or tuples and fields). In a strict mathematical sense, the term table is actually referred to as a relation and accounts for the term “Relational Model”. In mathematics, a relation is a representation of a set.

The expression attribute gives a good description of the purpose of a column – it characterizes the set of rows associated with it. Each column must be of a particular data type and each row must have some unique identifying characteristics called “keys”. Data change is typically more efficient when done using the relational model while data retrieval may be faster with the older Hierarchical Model which has been redefined in model NoSQL systems.

Computer programming language is a set of detailed instructions for computers or machines for performing specific actions. Through a programming language, we can control the behavior and output of a computer via accurate algorithms. A programming language is also called a computer language or programming system. The computer performs with various programming languages, such as SQL, Java, C++, Python, etc.. These languages allow computers and machines processing the large and complex data more effectively and quickly. That is the reason we find them valuable to organizations, particularly in the creation of system database management services. Read More
