Con el auge de los sistemas de bases de datos NoSQL los cuales implementan modelos de datos diferentes al relacional como son las bases de datos documentales o de grafos, ha surgido el concepto de Persistencia Políglota. Ésta sostiene que debido a la gran variedad y cantidad de representación de los datos, y los diversos servicios que pueden dar las aplicaciones hoy en día; es necesario el uso de más de un tipo de sistema de almacenamiento para ser capaz de cubrir de forma eficiente todas las necesidades de la aplicación que use dicho sistema. En este trabajo se busca dar una idea general de las Aplicaciones de Persistencia Políglota describiendo las posibles arquitecturas que hacen uso de las bases de datos NoSQL y su funcionamiento, se estudian algunos casos de éxito y se lleva a cabo un caso de estudio usando MongoDB y Neo4j.
El presente documento es una guía amigable de LaTeX para la redacción de protocolos de investigación con algunas sugerencias de como debe ser presentada y redactada la propuesta. Esta guía actualmente es utilizada por el departamento posgrado de ingeniería electrónica del Instituto Tecnológico de Morelia.

Gene regulatory networks have an important role to study the behaviour of genes. By analysing
these Gene Regulatory Networks we can get the detailed information i.e. the occurrence of diseases by
changing behaviour of GRNs. Many different approaches are used (i.e. qualitative modelling and hybrid
modelling) and various tools (i.e. GenoTech, GINsim) have been developed to model and simulate gene
regulatory networks. GenoTech allows the user to specify a GRN on Graphical User Interface (GUI) according
to the asynchronous multivalued logical functions of René Thomas, and to simulate and/or analyse its
qualitative dynamical behaviour. René
Thomas discrete modelling of gene regulatory network (GRN) is a
well known approach to study the dynamics of genes. It deals with some parameters which reflect the possible
targets of trajectories. Those parameters are priory unknown. These unknown parameters are fetched using
another model checking tool SMBioNet. SMBioNet produces all the possible parameters satisfying the given
Computational Logic Tree (CTL) formula as input. This approach involving logical parameters and conditions
also known as qualitative modelling of GRN. However, this approach neglects the time delays for a gene to
pass from one level of expression to another one i.e. inhibition to activation and vice versa. To find out these
time delays, another modelling tool HyTech is used to perform hybrid modelling of GRN.
We have developed a Java based tool called GenNet http://asanian.com/gennet to facilitate the
model checking user by providing a unique GUI layout for both qualitative and quantitative modelling of GRNs.
As we discussed, three separate modelling tools are used for complete modelling and analysis of a GRN. This
process is much lengthy and takes too much time. GenNet assists the modelling users by providing some extra
features i.e. CTL editor, parameters filtering and input/output files management.
GenNet takes a GRN network as input and does all the rest of computations i.e. CTL verification,
K-parameters generation, parameter implication to GRN, state graph, hybrid modelling and parameter
filtration automatically. GenNet serves the user by computing the results within seconds that were taking hours
and days of manual computation
