But between the multiplication of data, the tangle of flows between applications and the wide variety of infrastructure choices, these IS are increasingly complex. So, for a coherent, global vision of their data, organizations need to put in place a functional, organic system architecture.<\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"what-is-system-architecture\">What is system architecture?<\/h2>\n\n\n\n<p>IS architecture aims to build information system models. The aim is to provide a global, consolidated vision of the organization&#8217;s <a href=\"https:\/\/liora.io\/en\/data-mesh-definition-importance-applications\">data structure.<\/a><\/p>\n\n\n\n<p>To achieve this, <a href=\"https:\/\/liora.io\/en\/corba-infrastructure-definition-and-benefits\">system architecture<\/a> is based on 3 essential elements:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Operational vision<\/strong>: this is the objective of the information system.<\/li><li><strong>The functional vision<\/strong>: which provides a global understanding of how the IS functions.<\/li><li><strong>The organic vision<\/strong>: all the components that enable the IS to function properly, such as hardware, software and human resources.<\/li><\/ul>\n\n\n\n<p>And there&#8217;s a fourth essential element: business needs. System architecture must not only meet these needs at a given moment. It must also adapt over time to the organization&#8217;s strategy, processes and technological innovations. In other words, it must be capable of evolving rapidly according to the company&#8217;s needs and constraints.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"why-is-this-so-important\">Why is this so important?<\/h2>\n\n\n\n<p>With the constant increase in data volumes, the disparity of <a href=\"https:\/\/liora.io\/en\/terraform-and-azure-devops-pipelines-a-comprehensive-guide-for-infrastructure-as-code\">infrastructure<\/a> choices, the addition of application bricks, the widespread use of SaaS applications&#8230; information systems are becoming more and more complex.<\/p>\n\n\n\n<p>Implementing a system architecture helps to simplify them. Let&#8217;s take a look at the benefits:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Data understanding:<\/strong> without a clear system architecture, data can become unreadable, costing the company its competitive edge and productivity.<\/li><li><strong>Collaboration:<\/strong> the vast majority of organizations still operate in silos, because their information systems are too complex to use globally. Conversely, a system architecture that is comprehensible to all employees facilitates the exchange of relevant information between different departments.<\/li><li><strong>Cost control:<\/strong> by continually adapting to the organization&#8217;s needs, the information system enables it to reduce costs. Not to mention the savings achieved through greater productivity.<\/li><li><strong>Security:<\/strong> the system architecture defines a certain number of standards, particularly in terms of data exchange and transfer.<\/li><\/ul>\n\n\n\n<p>Ultimately, an efficient <strong>IS architecture<\/strong> optimizes the flow of information, and guarantees the uniqueness, comprehensibility and <a href=\"https:\/\/liora.io\/en\/data-sources-understanding-the-definition-and-inner-workings\">reliability of data.<\/a><\/p>\n\n\n\n<figure class=\"wp-block-image size-full\" style=\"margin-top:32px;margin-bottom:32px\"><img alt=\"System architecture components and relationships\" decoding=\"async\" height=\"500\" loading=\"lazy\" src=\"https:\/\/liora.io\/app\/uploads\/sites\/9\/2026\/08\/en-recovered-4dedafd6ea06-architecture-systeme-1.jpg\" style=\"width:100%;height:auto\" width=\"900\"\/><\/figure>\n\n\n\n<div class=\"wp-block-buttons is-layout-flex wp-block-buttons-is-layout-flex is-content-justification-center wp-container-core-buttons-is-layout-5ee10de4\" style=\"margin-top:32px;margin-bottom:32px\"><div class=\"wp-block-button\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/liora.io\/en\/courses\/data-ai\/data-analyst\">Learn how to deploy a system architecture<\/a><\/div><\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"how-to-implement-a-functional-architecture\">How to implement a functional architecture?<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"definition-of-requirements-and-specifications\">Definition of requirements and specifications<\/h3>\n\n\n\n<p>Implementing an efficient system architecture begins with defining the specifications. This involves identifying all the <strong>requirements for designing a high-performance, reliable IS.<\/strong><\/p>\n\n\n\n<p>To this must be added the specifications that will enable the <strong>IS to achieve its objectives.<\/strong> To define these specifications, however, you need to start from the organization&#8217;s core business, so as to adapt them to its real needs and strategic objectives. In other words, it&#8217;s not the technical constraints that must guide the organization&#8217;s activity, but the business needs that define the system architecture. It&#8217;s a top-down approach.<\/p>\n\n\n\n<p>That said, it is also essential that the information system integrates perfectly with the organization&#8217;s environment (the applications and tools used internally, the processes in place&#8230;). This is made possible by a <strong>SOA (Services Oriented Architecture)<\/strong> approach, in which all services are standardized and reusable within the architecture itself and all other applications in the ecosystem.<\/p>\n\n\n\n<p>As such, the system architect will establish links between business needs, applications and technical constraints, in order to design a coherent, high-performance IS.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"modeling-the-target-is\">Modeling the target IS<\/h3>\n\n\n\n<p>Once the requirements and specifications have been defined, the architect maps the current structure and identifies areas for improvement in order to design the target information system.<\/p>\n\n\n\n<p>For example, he will need to answer the following questions:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>How are<a href=\"https:\/\/liora.io\/en\/transactional-database-model-all-about-this-type-of-database\"> data modeled<\/a>?<\/li><li>How does it circulate?<\/li><li>What malfunctions and steps need to be optimized?<\/li><li>How can exchanges be improved?<\/li><\/ul>\n\n\n\n<p>Good to know: it&#8217;s essential to continuously map the IS structure. This systemic modeling ensures that companies don&#8217;t end up with an obsolete architecture unable to meet new needs.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"join-liora-to-learn-how-to-design-a-high-performance-system-architecture\">Join Liora to learn how to design a high-performance system architecture<\/h2>\n\n\n\n<p>Implementing a functional, <strong>reliable and high-performance system architecture<\/strong> is only possible with specific skills.
