We will need to create as many as objects based on the number of order entries. It is also called as BO (Business Object) or a DTO (Data Transfer Object) – due to its nature of transferring the data from one layer to another within an application. We need to carry all the properties of an Order in a single entity – which is a Wrapper Object. This is a very essential script that carries the class structure for a POGO (Plain Old Groovy Object) to have the essential properties of an Order – like the Order Id, Date, Customer Name, Currency, Price, Country, Payment Mode etc., In this section, we will write a few simple Groovy Scripts pertaining to the business purpose.

Application Business Scripts – We will write a few simple Groovy scripts for creating random Order entries and write them into a delimited file (pipe separated) in a directory so that our Database scripts will be able to parse (read and process) them for inserting them into Database.In Java, it is called as POJO (Plain Old Java Object) where in Groovy it is called as POGO (Plain Old Groovy Object). It is a common practice to wrap all the relevant attribute into an Object of a corresponding class. Business Model (Domain Object) – We will create a Domain Object (Business Object) to carry all the information of an order as a single entity, otherwise it will be tedious and an overhead if we were to pass all the individual attributes of an order.Planning and approachįor our order processing script, we will do the following in order as a step by step approach. We will be using Groovy language basics for covering this example like String Concatenation, Collections – List and Map, File Handling, SQL Handling etc., You may please check the References section at the bottom of this article to have a quick glance on each of the topics to facilitate your understanding of scripts. Upon finding the files, it will process them and move the files into a different directory, so as not to process them in the next iteration. Our Groovy Script will continuously monitor the same directory in the file system at regular intervals for the new files. We will parse (read and process) the line entries from the file and add an Order for each line into the Database to store it permanently.įor the sake of our example, imagine a system that dumps such a flat file in our file system at regular intervals. We will see an example of an Order Processing System where we will get the details related to an order in a flat file (a pipe separated / delimited) file where each line contains the information pertaining to an order.

If you are an experienced Java professional for more than 5 years and have explored Groovy for sometime, you would undoubtedly agree with the above statement. Groovy is a programming language which can be used as a Scripting language due to its very simplified syntax which is very easy to use. In general, the scripting languages have one thing in common – their simplified syntax and ease of use as that is the main attracting point to the users (or developers) who aims to get the job done quickly and efficiently. However there are various scripting languges and tools with their owns pros and cons depending on the features they have to offer, the simplified syntax they have in store, the limitations they have by nature etc., Script is an executable program which is accomplished to automate the mundane tasks in a simple and easy manner that requires a minimal or no human intervention thereby resulting in time saving.
We use MySQL V 5.6 for Windows, with JDBC driver for MySQL - MySQL JDBC Connector 5.1.29. For our example Order Processing System, we will use MySQL open source database.
