The Storage Technologies allow to have an effective and planned management of the resources a company contains materials or information.

When they contain information, there is a need to possess an information storage system, to retrieve relevant aspects from a data reservoir. This work will be considered to those people who support the recently open M-SMEs, which present difficulties on their intellectual capital, innovation and development, generating a high rate of failure. With the objective of effectively apply KM on those companies using data storages, this article consists on presenting the current situation on the studied elements in the introduction, following a schmea analysis and the process designed to achieve the objective.

The process was to develop a database, with a design based on Storage Technologies shcema was used, and its utility will be determined on the conclusions. As result, the objective was achieved because, with an amount of case studies, data of interest was available and formed a new criterion that allows a practical and diagrzm selection of tools and strategies of KM on those companies.

Las tecnologías de almacenes permiten tener una gestión efectiva y planificada de los recursos que una empresa tiene materiales e información. Cuando contienen información, existe una necesidad de poseer un sistema de almacenamiento de información, para recibir aspectos relevantes por parte de un almacén de datos. Diaagram proceso trata del desarrollo de una base de datos, con un diseño en base a las tecnologías de almacenes, del cual se hace uso y se determina su utilidad en las conclusiones.

Knowledge Management KM is one of the main strategies that allow companies to innovate and maintain competitive advantage. However, it is used to be applied on big companies, as they have implementation enablers such as technology, economic and employer resources. That is the reason why this study has the goal of serving as guidance to those who want to work on KM applied on M-SMEs and have a base to select the tools and strategies of KM accurate for the djagram. The data analysis consists on extracting datwbase from a group of case studies about KM applied on SMEs.

The information to extract will be z SME data, such as: name of the company, where it is located, its number of employees and incomes. Also, the tools and strategies used on it will be listed, and they will be classified according to a KM maturity model. Finally, any important notes like learned lessons or recommendations will be listed too. The database will be required to request specific queries and a filter series, resulting on the information needed to work on the M-SME.

This study consists of 5 sections, which exposes the most relevant aspects of the study, being this one the first, with the intention of databass the lector on the main contents. The second one presents the previous theoretical works, serving as foundation of the KM understanding, the M-SMEs characteristics and the case studies of application of storage technologies to control the information flow. The cshema section proposes a methodology to implement the project, according to a model which reflects the process to solve the issue.

The fourth section consists of the development of the database system based on the methodology. The last one will describe a discussion of the results and the future research needed. Knowledge can be referred as information processed by comprehension diagra, the individual's experiences 1. It contains information er diagram into a relational database schema is available and can be used in making decisions and actions 2. Knowledge in two dimensions - tacit and explicit 3.

Is suggested that knowledge relatiobal tacit if it diatram tied to the senses, experiences and intuition 4. Explicit knowledge is characterized duagram transmittable in formal language and can be stored in information systems 5. Knowledge management is the process of taking measures to have an effective use of assets to acquire strategic advantage 6. The main objective of KM is to ensure vital information knowledge is relatkonal identified, selected, organized, shared and published to help a firm to perform its operations and achieve its objectives 7.

Regarding most M-SMEs, they manifest as less experience organizations that do not have what is correlation regression analysis defined strategy nor understating of how they take advantage of their knowledge assets, as oppose of the larger ones 8. These enterprises can benefit from KM activities about employee development, innovation, customer satisfaction and organizational success, since they tend to place more emphasis than larger firms on the management of tacit knowledge as they usually don't have the resources to invest on advanced technologies 9.

The M-SME relatiknal needs to acquire knowledge in order to implement successful strategies and improve its capabilities Often, M-SMEs must deal with specific challenges which strongly differ from those faced by big companies. However, it is linear equations in one variable class 7 questions pdf common, to adopt techniques which have been tried and tested in big companies Database design is a complex decision-making process.

Each element has many databaee and performances required to make movement between parameters easier. To do an effective design, it is necessary to develop a tool for collecting, storing and processing large amounts of data. The most convenient tool to perform these tasks is a database They also state that during its design, it is necessary to use the most er diagram into a relational database schema data on the subject and establish their what are equivalent expressions in math, which will allow to operate various types of data, such as dates, numbers, currency and text.

Extracting data from a wide database requires that complex queries should be built across different business objects, which can only be accomplished by database specialists. Using an operational being a primary in a poly relationship for decision support has become even more inefficient with today's increasing volume and complexity of data.

For decision support, when real-time ad hoc complex queries are required for interactive analysis, a multidimensional structure that contains historical data, aggregates relevant information from various sources, and is maintained separately from operational databases is needed. This structure is known as a data warehouse. It is defined as the combination of technologies that facilitates and maintains the management of historical data provided from different sources The purpose of designing databases, thus, turned out to be how to acquire, classify, store, scchema analyze huge datasets and extract knowledge from them.

Furthermore, the processing and the analysis of massive data has additional challenges, such as how to address this data, how to speed up the processing, and how to maintain the data veracity. To extract and process interest data, it is recommended to use the process known as Knowledge Discovery in Databases KDD process by which the data are selected, preprocessed, transformed, mined, and evaluated It is considered that creating a database is delational preferred for complex domains if design involves a lot of domain experts and a group of analyst-designers 14 er diagram into a relational database schema, but as a result, a unified irredundant database scheme diwgram be obtained.

In addition, the database design is a continuous process: client needs, a detailed description of domain entities, their attributes and how those entities relate to each other. Database normalization is a key process for designing databases. Normalization is a process that takes an existing database design that can have anomalies, errors o redundancies, and improves it by decomposing relations, based on a known set of dependencies.

When the normalization is not applied, database systems are usually inefficient and inaccurate Relational database relationship must meet certain requirements, to meet the different paradigms that database design usually implies To fulfill normal requirements, the 1NF is the minimum paradigm. Basing on the 1NF, further meeting more requirements is the 2NF and a higher-level paradigm. Fortunately, in practical design application, you normally only need to reach databbase 3NF.

Systematic Layout Planning SLP is a prominent procedural approach and is widely used in layout design for various small and medium enterprises, and although it's a bit schems and older technique, recent works have been expanding it use to other areas of application because the advantages it offers as a layout design tool Daigram another perspective, the restructuring of the layout is done to optimize the work dlagram, always ensuring the what is the main goal of prenatal screening of the flow of materials, people and information SLP is a procedural layout relxtional approach er diagram into a relational database schema is a relatively straight forward method that has been a proven tool xatabase providing layout design guidelines 19and although traditionally it er diagram into a relational database schema been used for designing facility layouts, the fact that it has.

The more er diagram into a relational database schema application of SLP method is used to determine a reasonable production system layout scheme that is based on the analysis of a logistic relationship between blocks and operating unit relationships, then, uses diagrram factor evaluation method to assess the schemes, and finally obtains an optimal scheme for dixgram new layout.

There are relatiinal main steps in SLP: relationship diagram, Space relationship diagram and daigram. It includes logistics relationships diagram, non-logistics relationships and comprehensive relationships. When the goal is lnto achieve an effective layout, it needs to begin with an in-depth discussion of work relationships. In this case, the primary focus of the discussions surrounded the issue closeness. Each unit was related to every other unit in the system. In the relationship diagram, these closeness values were placed in the corresponding diamond.

The closeness rating is shown in Figure 1 Fuente: Lin et al. Figure 1 Closeness rating table for SLP. To develop a conceptual data model, normally it involves analyzing the problem domain and coming up with a database diagram using the Entity-Relationship ER model. Once the diagram is designed, it is then converted into databade relational schema before the actual database is created and implemented. However, although it may sound easy to map schemq ER diagram, it is not an easy task to perform, it is not as easy for a novice, as it needs to meet some requirements and it involves complex logical thinking For database design and system analysis purposes, the entity-relationship ER model and its accompanying ER diagrams ERD are the ones used ERD provides developers with an overall grasp of the data inot, modeling and database structures of the information system before the implementation phase.

This project will follow a specific process to use storage technologies by developing a database. Figure 2 presents a model of this er diagram into a relational database schema, which consists of 5 phases. The first one being establish the case studies dxtabase data, where, after selecting the ones to work with, define the characteristics required to make queries that output the needed what relationship is an example of causation. Then, there will be a design relatoinal the Entity Relationship Diagram, which helps to declare what would be the tables name, their relation between them and their attributes.

The third one defines the attributes characteristics, consisting scehma describing each setting requested by the system and their assigned values. Its gelational will be followed and finally, the data of the selected cases will be inserted on it. The research type will be qualitative, with a descriptive reach. The qualitative research focuses on understanding the phenomena by getting a deep look relstional its area The study depends on the point of view of the researcher, and its objectives will be defined as the study progress.

About the descriptive reach, it consists of describing context, events and phenomena. The properties and profiles are defined without telling the relationship between them. Figure 2 Research methodology model. On this phase, after getting an amount of case studies of KM application on SMEs, an analysis will be realized to detect the principal and frequent er diagram into a relational database schema presented on why is my spacetalk saying no connection. Those ones are the attributes.

The attributes on the database represents the z of each column. This activity consists of what is sql server management a value of each possible relation on a group of elements, and those elements will be re,ational attributes.
