Development tools application solutions are a very important part of the personal computer platform. The popularity of the platform depends on the flexibility, wealth, convenience and reliability of these tools. A platform without application development tools for it ceases to exist.
All platform providers supply and development tools applied solutions in one form or another. Operating system manufacturers offer all kinds of compilers and interpreters, database management systems, communication systems (for example, e-mail). Of course, solutions for popular operating systems are offered not only by vendors, but also by other vendors.
For platforms where the ability to develop solutions directly on them is limited (for example, for cell phones), manufacturers offer development tools operating under a popular and powerful operating system (Windows, Linux). In addition to these tools, a target platform emulator is provided on which you can debug your solution without using the target platform directly.
Currently, solutions are gaining popularity that ensure the independence of the developed application solutions not only from the hardware component of the platform, but also from the operating system. The most popular solutions of this kind are Java and Net.
The main idea of these platforms is to create a "virtual machine" - a special software package that operates on a specific hardware platform and on a specific operating system. The application program is processed virtual machine which translates "virtual instructions" into platform-specific instructions. As a result, it turns out that the program for the virtual machine functions on many bundles "hardware - operating system"without rework. The only condition is the availability of a virtual machine for a specific software and hardware solution. The most common hardware-independent platform is Java.
There is a certain class of software products - constructors, the use of which is limited to any subject area. These products implement not only basic functionality, but also flexible means of creating solutions in a specific field of activity. Such software products are often referred to as application platforms.
An application platform is understood as a runtime environment and a set of technological solutions used as a basis for building a certain range of applications. In fact, applications are based on multiple platforms in a layered environment. It is important that the platform provides the developer with a certain model, as a rule, isolating him from the concepts and details of lower-level technologies and platforms.
The key quality of the application platform is the sufficiency of its means to solve the problems facing business applications. This ensures that there is good consistency among all the technologies and tools that the developer uses. Another important point is standardization. The presence of a single application platform for a large number of applied solutions contributes to the formation of a common "cultural layer" that includes both people (programmers, analysts, users) and methodology (typical data structures, algorithms, user interfaces). Relying on this "cultural layer", the developer spends a minimum of effort to find the necessary solution in almost any situation, from the inclusion of a new specialist in the project and ending with the implementation of any subsystem of a business application according to a typical methodology.
A typical representative of special application platforms is the 1C: Enterprise system. The system itself is a flexible, customizable constructor that provides the solution developer with "more applied" methods and tools compared to traditional programming languages, that is, such a platform is a set of different mechanisms used to automate economic activities and not depending on specific legislation and accounting methodology.
There are complex application systems of the scale of corporations, which are the basis for the reliable conduct of large business, the so-called ERP-systems (Enterprise Resource Planning Systems). These systems are also an application platform that can be flexibly configured in its own subject area.
2.5. Platform selection criteria
Choosing a platform is an extremely difficult task, which consists of two parts:
There are several reasons due to which it is rather difficult to assess the capabilities of the platform with the selected set of components that are included in the system:
- such an assessment predicts the future: expected combination of devices, future use of software, future users;
- the configuration of hardware and software is associated with the definition of many inherently heterogeneous system components, as a result of which the complexity increases rapidly;
- the speed of technological improvements in hardware, functional organization of the system, operating systems is very high and is constantly growing. By the time a component is widely used and well understood, it is often viewed as obsolete.
- information available to the consumer about hardware, operating systems, software is of a general nature. The structure of the hardware that powers software systems has become so complex that experts in one area are rarely experts in another.
The choice of a particular platform and configuration is determined by a number of criteria. These include:
- Cost-performance ratio.
- Reliability and resiliency.
- Scalability.
- Software compatibility and portability.
Cost-performance ratio. The emergence of any new direction in computing is determined by the requirements of the computer market. Therefore, computer designers do not have one single goal. A mainframe or supercomputer is expensive because cost performance has to be ignored in order to achieve these goals when designing high-performance designs. Another extreme example is a low-cost design, where performance sacrificed to achieve low cost. This area includes personal computers. Between these two extremes, there are constructions based on the relationship cost - performance, in which developers find a balance between cost parameters and performance. Typical examples of these types of computers are mini computers and workstations.
Reliability and resiliency. The most important characteristic of a hardware platform is reliability. Improving reliability is based on the principle of preventing malfunctions by reducing the rate of failures and failures through the use of electronic circuits and components with a high and ultra-high degree of integration, reducing the level of interference, light modes of operation of circuits, ensuring thermal modes of their operation, as well as by improving methods for assembling equipment parts of a personal computer.
The introduction of fault tolerance requires redundant hardware and software. The structure of multiprocessor and multicomputer systems is adapted for automatic reconfiguration and provides the ability to continue the operation of the system after a malfunction occurs. Reliability includes more than just hardware, but also software... The main goal of improving the reliability of systems is the integrity of the data stored in them.
Scalability must be supported by the architecture and design of the computer, as well as by appropriate software tools.
The addition of each new processor in a truly scalable system should yield predictable and predictable throughput at an affordable cost. Really real increase in productivity difficult to estimate in advance, since it largely depends on the dynamics of the behavior of applied problems.
The scalability of the system is determined not only by the hardware architecture, but also depends on the inherent properties of the software. A simple transition, for example, to a more powerful processor can overload other system components. This means that a truly scalable system must be balanced in all respects.
Software compatibility and portability. Currently, one of the most important factors determining modern trends in the development of information technology is the orientation of computer equipment suppliers to the application software market. This is primarily due to the fact that it is ultimately important for the end user software, allowing to solve its problems, and not the choice of one or another hardware platform. The transition from homogeneous networks of software-compatible computers to the construction of heterogeneous networks, including computers from different manufacturers, radically changed the point of view on the network itself: from a relatively simple means of exchanging information, it turned into a means of integrating individual resources - a powerful distributed computing system, each the element of which best suits the requirements of a specific application.
This transition has put forward a number of new requirements:
Firstly, such a computing environment should allow flexible changes in the number and composition of hardware and software in accordance with the changing requirements of the tasks being solved.
Secondly, it should provide the ability to run the same software systems on different hardware platforms, i.e., provide software portability.
Thirdly, this environment must ensure that the same human-machine interfaces can be used on all computers in a heterogeneous network.

Formulation of the problem.
The IS includes various components: computing, peripheral, software, information, communication and technological. There are a lot of possible options for each component, which gives many outcomes for the design of the system as a whole and its development. In this regard, as the basis of IP, some established complexes of basic tools are usually considered, which are now called platforms. Any platform is based on computing and basic software. All other decisions in the system largely depend on the choice of these components.
In different parts of a complex system, different platforms can be used: some - as servers of different levels, others - at the workstations of users and employees of information departments as workstations. The choice of platform options is a key decision in the design of an information system.
In fact, this is always an important and complex problem that needs to be solved when building any IS for the most varied purposes. If the task is set more strictly - to substantiate the optimality of the chosen platform options, then its formulation and solution require sufficiently voluminous and science-intensive research (formation of models, determination of optimality criteria, as well as modeling, in some cases quite laborious). There are no uniform recommendations for solving these problems. Some firms use efficient versions of systems in which, due to the transfer of basic operations from a central machine to workplaces, the degree of parallelization of the computational process increases. Others, on the other hand, prefer consolidated central systems that provide parallelization of processes through better control and, at the same time, a high degree of information security.
Structure options.
In addition to the variety of possible combinations of means that can be used as the basis for IS, it is necessary to take into account the many options for organizing the system, technological processes that can be implemented in the system, and the standards corresponding to them, as well as the variety of personnel and management decision strategies.
Economic indicators serve as natural criteria in the problems of choosing solutions for the development of the system. In these, the main variables may be costs. The costs of purchasing and installing a complex of hardware, software and other means do not exhaust all costs. Personnel training, preparation and maintenance of premises, development of application programs, support of technology and other purposes also require funds, so the chosen simple option may turn out to be suboptimal, taking into account all the associated costs, i.e. by TSO.
In these conditions, reducing the problem to a choice between a simple central and a distributed system also does not reflect the situation in its entirety. So, according to the analytical company ITG, the central system based on the IBM ES / 9000 mainframe with a network of 50 or more IBM PCs has clear advantages over the distributed one: the average total cost of one PC user workplace in this system is about 2 times lower, and the average the total cost of a transaction is about 7-10 times lower than on the network.
The complete downsizing has been left behind, and the opposite process is already underway. It is recognized that the centralized maintenance of computer resources with a large number of users is more economically profitable than the distributed one. According to ITG, for financial systems, the cost per user per year for a decentralized system based on UNIX servers is $ 11.6 thousand, when using one UNIX server - $ 4.9 thousand, and the IBM S mainframe / 390 - $ 3.4K (this refers to the 500 user tier; with 1000 users, the S / 390 advantage is even greater).
According to the large systems department of IBM Eastern Europe, as the number of users grows in a distributed system, the cost of one workplace increases, while in a centralized system, on the contrary, it falls. In addition, the release of new processors leads to a decrease in the cost of 1 MIPS: at the beginning of 1999 this price in different systems was already 5-6 thousand dollars and is decreasing more and more. This leads to a corresponding reduction in the threshold for the number of seats, at which the maintenance of one seat in systems based on the S / 390 mainframe is less than in a distributed system, and the use of the mainframe becomes more profitable. At the beginning of 1999, this border was at the level of 100 jobs.
The cost of e-mail per year per person with the number of users from 1 to 5 thousand dollars in decentralized systems based on Windows NT is $ 287, in centralized systems based on NT - $ 149, on UNIX-based systems - $ 116 and on S / 390 base - $ 88.Total cost of ownership (TCO) per year per user working with online transaction processing applications centralized servicing UNIX servers is almost $ 5.5 thousand, and for mainframes - about $ 3.1K Distributed Windows NT-based systems are less cost effective.
True, when trying to apply this statistics to Russian conditions, one must remember the domestic specifics. Here, first of all, one should take into account the relatively lower level of wages in our country, while the cost of labor in the "American" estimate makes a decisive contribution to the total costs with a large number of users. Many other cost items are also related to the level of wages in the industry. Yet the desire for centralization is evident. So, in March 2000, the superserver SUN Entegrrise 10,000 was installed in the administration of the Ministry of Taxes and Duties in Moscow. It includes:
- 16 Ultra SPARC 400 MHz processors;
- 8 GB of RAM;
- 127 GB StorEdge A 5200 main disk array;
- the operating system Solaris 7;
- Oracle DBMS 8.1.
About 4 thousand users are connected to the "Unified State Register of Taxpayers" subsystem.
A seminar held in Krasnoyarsk in 2000 showed that in this region customers are showing interest in systems even older than RISC servers, for example, the AS / 400 and S / 390 platforms.
At the same time, the trend of downsizing of systems is clearly preserved. However, the need of the top management of the system for its high security and manageability from the center cannot be met by cheap and affordable PC-based systems and leads to the choice of systems based on UNIX or more powerful architectures typical for medium-sized machines (for example, IBM AS / 400) , or even mainframes (like IBM ES / 9000).
Developing a client-server strategy is a striving to combine the merits of both approaches: with powerful tools in the workplace, have a manageable and secure system as a whole. There are also some peculiarities along this path.
So, when moving from a two-tier computing architecture, including a server and a client workstation, to a three-tier one, which also includes an intermediate application server, both the cost of developing systems and the total price of DBMS licenses, if they decrease, are not very much. The cost of maintaining applications is reduced significantly: instead of installing and configuring software on each workstation (albeit remotely, as it happens in the two-tier version), the system administrator of the three-tier system will install and configure the application only on servers. Loading of client interfaces to workstations will happen automatically; therefore, the number of full-time administrators can be reduced.
In these conditions, the enterprise, which is going to purchase a new "client-server" application, the question arises:
which is more profitable - buy a two-tier system and hire two more system administrators to maintain it, or purchase a three-tier system, at the same time buying one more computer to install the application server, and hire only one new system administrator? The answer largely depends on what is cheaper - the server or the worker.
Another important factor in these conditions is the need to take into account the prospects for the development of the system. As users set tasks, resource requirements increase and the system is loaded above its nominal parameters, reducing the quality of work. In practice, many requirements can be effectively met by both powerful low-end computers and low-power high-end computers: for example, a powerful PC or UNIX machine, UNIX machine or AS / 400; AS / 400 or ES / 9000. As a rule, all families of machines allow a significant increase in resources (performance, memory capacity, number of processors) inside themselves, called scaling, which is always cheaper than changing platforms. This allows the system to exist for a fairly long time within the same platform.
The transition from one platform to another for any system is not painless and requires efforts, time and funds, in some cases very significant. The enterprise loses in income, while sometimes the entire system undergoes significant transformations. On this basis, the choice of older models of the computer family seems to be risky due to the prospect of quickly using the possibilities of their expansion.
For many years, IP in our country has been developing on the basis of uniform standard solutions. In the 90s. various platform options have already appeared, and the choice of a platform for the system seems to be a task of multi-criteria optimization, taking into account specific conditions.
Concluding this section, we can once again highlight the following main features of the current period and, most likely, a fairly long-term perspective of the production of these funds:
- creation of a single world informatization market;
- the disappearance of borders in the activities of companies;
- continuous development of the technological base of all components of the system, mutual penetration of various technologies;
- no sharp boundaries between production sectors:
- the same basic elements are used, software and information means are compatible, respectively, etc .;
- blurring the boundaries between firms (numerous corporate projects, joint ventures, mergers and mutual sprouting of firms, partial participation in capital);
- "denial of negation": the creation and introduction of new products with better characteristics significantly undermines the interest in those that are still on sale. Thus, the main components of IT - operating environments, systems for working with data, tools for creating application programs and complex applied systems, as well as computing means - ensure the creation of tenacious structures that allow for all-round development.
Of particular note is the increase in power and the improvement of the operational characteristics of powerful computers, on the one hand, and the significantly increased power of medium, mini- and microcomputers, on the other hand. As a result, on the basis of the latter, it became possible to build and develop such information systems and technologies for which powerful and superpowerful universal computers were previously used.

10.1.1 Concepts of IP Architecture
Architecture is the organizational structure of a system.Information system architecture - a concept
defining model, structure, functions performed and
the interconnection of the components of the information system.
Architecture is the basic organization of a system,
embodied in its components, their relationship with each other and
with the environment, as well as the principles that determine
system design and development.
Architecture is a set of meaningful decisions about
software system organization, recruitment
structural elements and their interfaces, using
which the system is assembled.
The architecture of a program or computer system -
it is the structure or structures of the system that include
program elements visible from the outside properties of these elements
and connections between them.
Architecture is the structure of an organization and its associated
system behavior.
System software architecture or
set of systems consists of all important design decisions for
about program structures and interactions between these
structures that make up systems.
11. Two groups of subsystems in the AIS structure:
AIS architecture is calleddistribution of functions according to its
subsystems and components, precise
defining the boundaries of these subsystems and
their interaction on management and
data as well as distribution
storage and execution of these subsystems
and components on various computers,
combined into a local
or the global computer network.
Two groups of subsystems in the AIS structure:
functional subsystems
supporting subsystems
12.
Under the architecture of software systemswe will understand the set of solutions
relatively:
organization of the software system;
selection of structural elements,
components of the system and their interfaces;
behavior of these elements in
interaction with other elements;
combining these elements into subsystems;
architectural style defining
logical and physical organization
systems: static and dynamic
elements, their interfaces and how they are
associations.
13.
The choice of IC architecture influencesthe following characteristics:
IC performance - quantity
work performed in the IS per unit
time.
System response time to requests
user (system response time).
Reliability - the ability to fail-safe
functioning for a certain
period of time.
