The main component of the data layer is the ontology-driven data access that is used for accessing external repositories ("archives, scientific collection, museums, art galleries, visual arts") and connecting them to the composition layer of the architecture.
The framework uses a standard enterprise layer architecture (i.e. web layer, application layer, service layer, business, and data layers) to identify components, and map compliance policies to corresponding Cisco products.
These components and interfaces fit into one of the three tiers: the presentation layer, the business logic layer, or the data layer.
These components can be separated into three conceptual layers as illustrated in Figure 1: (i) a top-level application layer, (ii) a data layer and (iii) a stream layer.
The meta data layer defines the application layer.
The classical division of the code divides it into a presentation layer, a domain layer, and a data layer.
This layer coordinates the commands requested, makes logical decisions and interacts with the data layer.
At the application layer, components may exhibit disparate data types and operations, and may have distinct business logics.
The architecture consists of three main layers: the presentation, domain and data layers, representing the interaction between the essential components of the solution Fig. 4 Similarity of the sequence and the 3D patterns in the Monoamine Oxidase B proteins.
We calculated Spearman rank correlation coefficients between the environmental variables and performed a principal component analysis (PCA) on all Bio-ORACLE data layers.
