Programming Transaction Management

Programming Transaction Management

What is the function of programming transaction management? How important is this to the company? These are some questions that need to find answered below.

What Is Programming Transaction Management?

Programming transaction management (PTM) is a collection of features in a programming language. That prevents data changes that are not performed in the right order. 

The ability to modify the data in a transaction is one of the most important features of any programming language. It allows programmers to change the state of the system. 

However, it also allows them to modify data in ways that do not conform to the business rules or produce incorrect results. In other words, PTM ensures that transactions are committed (or rolled back).

Following the constraints developed by the programmer. For example, if a transaction updates a column titled “Balance” and another column titled “Available Balance”.

It should be committed only if both values are changed. Also, if only one value is changed, then it must be rolled back.

If a transaction changes the value of a column in table 1, it must also change the corresponding value in table 2. If it does not change the corresponding value in table 2 then it must be rolled back.

In short, PTM ensures that transactions are consistent with existing business rules. And are applied in the correct order according to those rules. 

In this way, programmers can write code that modifies data without worrying about whether their code produces correct results. It is because they know that PTM will prevent incorrect results from being committed to the database.

How Important Is The PTM For The Company?

The importance of PTM to a company depends on the programming language used in the company. In languages such as C, C++, and Java, PTM is vital for ensuring data consistency and integrity.

It is because these languages provide low-level access to the database. Also allows programmers to change the data directly and without constraints. 

In contrast, high-level programming languages. Such as RPG or CL give programmers very little control over the database. 

They do so by providing built-in support for access to the database. And also preventing programmers from directly changing data. 

It means that transactions in these languages are always consistent with business rules. In other words, PTM is not necessary for these programming languages. 

However, if a company wants to use a high-level language like CL or RPG. Then it must use a product that provides PTM functions built into the language.

If they do not do so then they will have to use a separate product that provides PTM functions. As described above, PTM functions provide support for data consistency and integrity at all levels of programming language support.

In contrast, other products only provide support for data consistency at one level of language support or another. 

Conclusion:

The PTM is a vital feature for any programming language that allows programmers to change data directly. Such as C, C++, or Java. 

These languages do not have built-in support for PTM functions. In addition, if a company wants to use high-level languages like CL or RPG.

Then they must use a product that provides built-in support for PTM functions. 

Moreover, this product must provide PTM functions at all levels of language support provided by the language. Not just at one level of support or another.
