The governmental registry systems comprised a multi-layered architecture encompassing a database, an intermediary server, and a streamlined client interface. These systems catered to approximately 700 users and managed a substantial database of roughly 1000 gigabytes.Technological Components Employed:Database: Leveraged either Oracle 10 or MS SQL Server 2005Middle server: Implemented the Microsoft .NET Framework versions 2.0, 3.0, and 3.5, alongside WCF and the BLToolkit libraryClient: Utilized the Microsoft .NET Framework versions 2.0, 3.0, and 3.5, integrated with DevExpress controls.One of the applications, known as "Art-zvit," functioned as a client interface for the Certification Authority MASTERKEY. It stood as an autonomous application meticulously tailored for the generation and submission of financial reports to governmental bodies such as the State Tax Administration of Ukraine and the Pension Fund of Ukraine. This application harnessed a localized Microsoft Access database and integrated sophisticated techniques for data security, including encryption and digital signature methodologies.Technological Components in Use for Art-zvit:Local database: Employed Microsoft AccessApplication: Developed on the Microsoft .NET Framework versions 2.0, 3.0, and 3.5, featuring the inclusion of DevExpress controls and the Spreadsheet Gear component.
