Software product lines have emerged as a new software development paradigm of great importance. A software product line is a set of software intensive systems sharing a common, managed set of features, that satisfy the specific needs of a particular market segment or mission and that are developed from a common set of core assets in a prescribed way. Organizations developing a portfolio of products as a software product line are experiencing order-of-magnitude improvements in cost, time to market, staff productivity, and quality of the deployed products.

Anne Taulavuori. Component documentation in the context of software product lines. N2 - The use of third-party components in software system development is rapidly increasing. The product lines have also adopted this new tendency, as the COTS and OCM components are increasingly being used in product-line-based software engineering. Component documentation has become a key issue in component trading because it often is the only way of assessing the applicability, credibility and quality of a third-party component, especially for product lines in which the common architecture determines the decisive requirements and restrictions for components.

However, at the present time there is no standard model for component documentation, and, therefore, the component documents are often inconsistent, insufficient and of various quality.

The lack of a standard documentation model is thus one of the bottlenecks in component trading. The purpose of this thesis is to define the documentation requirements of software components and form a standard documentation pattern from these requirements. The documentation requirements are examined from the viewpoint of the software product lines, where the common product line architecture may define several specific requirements for a component.

The standard pattern is a skeleton of documentation, defining the content and structure for component documentation. The pattern ensures the documentation that assists the integrator in successful component selection, validation, integration and use within product lines. The development of the documentation is defined by identifying the roles responsible for the documentation and associating them with the pattern. Definition of the documentation pattern is not sufficient for the adoption of a new documentation practice.

An environment that supports the development of documentation is also required. This thesis also introduces the developed documentation system, which defines how the component documentation could be implemented. The system provides guidelines concerning how to document a software component.

It also offers the tools and technology for the development and handling of documents, and ensures that the developed documentation is in accordance with the pattern. In addition, the system is also applicable when the development of the documentation is split between different organisations.

An evaluation of the documentation pattern is presented at the end of this thesis. AB - The use of third-party components in software system development is rapidly increasing.

Software product lines - practices and patterns

Software is becoming larger and more complex mainly due to higher functionality of the product, software implementation of functions what used to be realized by hardware. As a result, increasing development and quality costs, frequent schedule overruns of software are becoming a business issue. To resolve this issue, we focused on Software Product Lines technology, which is one of commonalization, reuse technology. We developed technology for effective deployment, and trained expert human resources to lead the development. As a result, we deployed the technology to eight product groups in five years with each achieving the deployment purpose. The size and complexity of software for embedded products are increasing because of various factors.

Modelling is an essential activity in software engineering processes. It typically involves two meta-levels: one includes meta-models that describe modelling languages, and the other contains models built by instantiating those meta-models. Multi-level modelling generalizes this approach by allowing models to span an arbitrary number of meta-levels. A scenario that profits from multi-level modelling is the definition of language families that become specialized by successive refinements at subsequent meta-levels, hence promoting language reuse.

Long-standing standard practices in traditional manufacturing, the concept of production lines is relatively new in the software industry. A software product line is a set of systems that share a…. A software product line is a set of systems that share a common set of core technical assets, with additions and planned changes to meet the needs of specific customers or market segments. Software organizations of all types and sizes discover that when executed skillfully, the production line strategy can lead to enormous gains in productivity, quality and time to market. Software product lines are the culmination of extensive investigations by the Software Engineering Institute SEI at Carnegie Mellon University on how to "re-equip" leading software developers for production lines.

Architecture Design Pdf. Worked with design team to manage workload and deadlines and maintained project schedule and budgets. An in-depth literature review was conducted to identify green design and construction practices, design features of premium hotels, and major design conflicts between the twin goals of green building. Architectural patterns are similar to software design pattern but have a broader scope. Specific deep learning architectures 5.

Скрытые тенью, на него смотрели глаза Грега Хейла, глаза, полные ужаса. Тогда Стратмор понял, что Грег Хейл должен умереть. В ТРАНСТЕКСТЕ послышался треск, и Стратмор приступил к решению стоявшей перед ним задачи - вырубить электричество. Рубильник был расположен за фреоновыми насосами слева от тела Чатрукьяна, и Стратмор сразу же его .

 Да, но я на всякий случай заглянул в Интернет, запустив поиск по этим словам. Я не надеялся что-либо найти, но наткнулся на учетную запись абонента.  - Он выдержал паузу.

Повисла тягостная тишина. Когда Мидж заговорила, ее голос был мрачным: - Стратмор мог обойти фильтры. Джабба снова вздохнул.
