Computing strategyObjetive

Implementing the computer strategy to systematize the processes for all stages ofPopulation and Housing Census, using state-of-the-art technological platforms formultiplatform (Android, Windows) software applications development, on mobile devicesand for applications development in the web environment required by the project, as well asensuring a consolidated and secure technological infrastructure, such that theycontribute to an field operative with quality results in terms of coverage, integrity, andinformation consistency.

General planningMethodological bases

Of right or jure.

Usual residents of national territory and private and colectivedwellings.

Head of the dwelling, her/his spouse or a resident of 18 years oldor older.

General planningMethodological bases

Direct interview using one of the two questionnaires, also using online self-enumeration and telephone-assisted interview.

Basic form for exhaustive enumeration.

Long form for a probabilistic sample.

Social Assistance Housing (SAHQ).

Of locality for those that have less than 5,000 inhabitants.

Of the surroundings, in urban centers of 5,000 or more inhabitants and municipal head.

Operative designSystems

• Delimiting the geographical areas of responsibility of interviewers, supervisors, and direct responsible of field operation It delimits the operative responsibility areas using a simulated annealing

algorithm. It offers a solution that balances the workload and in compact geographic areas.

It establishes the interviewers route and/or canvass order, and dates of coverage.

Training system

WEB

• Providing operative personnel with necessary capabilities and tools for their functions execution through learning modules It download training materials: manuals, course agendas, presentations,

and exercises. Sending and receiving exercises for courses in combined

environments. Sending and receiving course evaluations.

Operative designTechnological training platform

Electron framework is used to generate the application that would run under the Windows operating system, and for the Android version, Apache cordova.

• Open source• Multiplatform applications (Mac, Windows and

Linux) of desktop with JavaScript, HTML y CSS - https://electronjs.org/ -

• Mobile apps with HTML, CSS & JS• Target multiple platforms with one code base• Free and open source- http://www.spanishdict.com/translate/Target -

The training application has been developed in JavaScript programming language under the Ecmascript6 standard (https://devcode.la/blog/que-es-y-por-que-aprender-ecmascript/). For information storage, the SQLite database was used.

• Standardize the recruitment and selection process of the personnel involved in the project to facilitate and expedite their recruitment.

Recruitment and staff selection

• Facilitating the activities follow-up related to the conformation of the operative responsibility areas.

Field expenses

• Controlling and facilitating the field expenses processing.

Logistic • Controlling the material resources provision to field personnel.

Data integrationand material distribution

• Transfering the fieldwork capture data to the central database. Distribute digital material to operative personnel.

Operative designOPERA system

• Facilitating the monitoring on contingencies prevention.Operativecontingencies

• Ensure registration and attention to incidents that occur during the operation in order that corrective measures are timely and effective.

Incidents

Massive mail • Establishing an immediate mean of communication with the operative personnel in order to provide instructions, clarify doubts, give warnings about updates, etc.

Documentsrepository

• Establishing a single way of distribution of various materials for the operation, as well as the information systems that are used before, during, and after the workfield.

Operative designTechnological platform of the system OPERA

Single Page App

(SPA)Seguridad

Backend Frontend

The main development tool for the Internet is Visual Studio .NET 2015 (https://www.visualstudio.com/es/vs/whatsnew/), which is a complete set of tools for the generation of web applications.

Also, AngularJS is used (https://angularjs.org/) because provides techniques for the creation of SPA applications (single-page application), which benefits the performance of the applicative, making lighter the requests to the server, for it makes requirements of only specific parts of the page.

On the other hand, with the use of (JSON Web Token-https://jwt.io/introduction/), a more secure communication is implemented and it facilitates the administration of the system users, assigning roles and permissions - Authentication: Once the user is logged in, each subsequent request will include the JWT, allowing the user to access routes, services, and resources that are permitted with that token. -

Oracle 12c is used to manage the database, which provides greater security and information availability.

USB for backup and transfer information between operative personnel.

GPS coordinates registry of the canvass of work areas, buildings, among others.

Use of voice and data service for communications between operative personnel, applications update, and device monitoring.

Use of the camera for reading the QR codes of labels, invitations of self-enumeration, and printed questionnaries.

Data collectionUse of QR and GPS

• Computer applications use from the cartographic update, data collection, to information exploitation.

• Canvass for collecting the information of questionnaires of urban environment and locality with GPS support, as well as updating the cartography that the interviewer will use.

• Data collection: direct interview in the dwelling with mobile devices, through a website with controlled access (self-enumeration via internet), via telephone (Call Center).

• Control of coverage, self-enumeration and printed instruments through the useof labels with unique folios (QR).

Data processingTechnological platform

• In information processing (coding and validation), tools developed with tha Java language are used.

• For the development of the cartographic update system, Java is also used, as well as the development of data access objects for intermediate processing.

• In the follow-up to the processes Visual Studio .Net 2017 is used and for the release offigures the 2015 version.

Results presentationTechnological platform

• For products generation, tools such as SAS, STATA, SPSS, Oracle databases and SQL server are used, as well as the Adobe Creative Suite.

• The SCINCE is based on the institutional platform MxSIGhttp://www.inegi.org.mx/geo/contenidos/MxSIG/default.aspx, which includes free software components and uses the R language for statistical analysis; for informationstorage, it uses PostgreSQL and for geospatial management PostGIS. MxSIG is the software platform offered by INEGI to its users to generate geographic information systems.

• The Panorama sociodemográfico de México and the consultation system of territorial integration and locality are developed in Visual Studio .Net 2017, using the Oragle 12c database.
