Basado en lo descrito en el documento “What Is The Difference Between System Analysis And System Design?”, elabore un cuadro comparativo en inglés de las dos fases del ciclo de desarrollo del software presentadas.
System Analysis The analysis of systems are all the steps that are performed to determine how a system will operate, taking into account the human part, physical plant, capital and means of diffusion, to perform this analysis can find if the system is viable, if Requires greater investment, which we require in physical plants, what difficulties we can present and how to solve them.
Differences
System Design The design is given after the analysis, it is the innovation that is wanted to do, and having planned to do, the design is what allows us to try to position ourselves with a product, and having decided whether to improve an existing product or creating A new one, the design is what will individualize us, doing something that is simple or elegant, fast or powerful, this being the implantation of all the data collected with the analysis

3. En el documento “Codd´s rules”, identifique la utilización de verbos modales. Extraiga diez (10) oraciones que incluyan estos verbos auxiliares e indique las variaciones correctas que podrían tener utilizando otros verbos modales y los verbos modales que no deberían utilizarse ya que cambiarían el sentido de estas reglas. 1. The system must (change to “have to”) (can’t be change to “may” because is an obligation) qualify as relational, as a database, and as a management system. 2. All data must must (change to “need to”) (can’t be change to “might” because is an obligation) be accessible. This rule is essentially a restatement of the fundamental requirement for primary keys. 3. It Can (change to “could”) (can’t be change to “must” because is an ability or possibility) be used both interactively and within application programs 4. This means that data can (change to “be able to”) (can’t be change to “should” because is an ability) be retrieved from a relational database in sets constructed of data from multiple rows and/or multiple tables. 5. This rule states that insert, update, and delete operations should (change to “ought to”) (can’t be change to “must” because is an advice) be supported for any retrievable set rather than just for a single row in a single table. 6. The distribution of portions of the database to various locations should (change to “may”) (can’t be change to “need to” because is a recommendation) be invisible to users of the database. 7. Existing applications should (change to “might”) (can’t be change to “will” because is a Suggestion) continue to operate successfully. 8. Changes to the logical level (tables, columns, rows, and so on) must not (change to “can’t”) (can’t be change to “would” because is a prohibition) require a change to an application based on the structure. 9. It must (change to “will”) (can’t be change to “could” because is a certain) be possible to change such constraints as and when appropriate without unnecessarily affecting existing applications. 10.All views that are theoretically updatable must (change to “must”)(can’t be change because is a strong obligation and is the only word to use in this case) be updatable by the system.

1. SDLC: The systems development life cycle (SDLC) is a conceptual model used in project management that describes the stages involved in an
information system development project, from an initial feasibility study through maintenance of the completed application. 2. Systems Analysis: system analysis as a problem-solving technique that decomposes a system into its component pieces for the purpose of the studying how well those component parts work and interact to accomplish their purpose 3. System Analysis and Design (SAD): The examination of a problem and the creation of its solution. Systems analysis is effective when all sides of the problem are reviewed. Systems design is most effective when more than one solution can be proposed. The plans for the care and feeding of a new system are as important as the problems they solve. 4. Relational database management system (RDBMS): RDBMS data is structured in database tables, fields and records. Each RDBMS table consists of database table rows. Each database table row consists of one or more database table fields. 5. Primary Key: A primary key, also called a primary keyword, is a key in a relational database that is unique for each record. It is a unique identifier, such as a driver license number, telephone number. 6. Database management system (DBMS): A database management system (DBMS) is system software for creating and managing databases. The DBMS provides users and programmers with a systematic way to create, retrieve, update and manage data. 7. Logical Data: Boolean is in computation that can represent values of binary logic, that is two values, values that normally represent false or true. It is usually used in programming, statistics, electronics, mathematics (Boolean Algebra), etc. 8. Data bases: Is an ensemble of data belonging to the same context and systematically stored for later use. 9. SAD: (Decision Support System) Information system that is designed to provide information and assist the manager or manager in making effective decisions. 10.DBSM: Database management system (DBMS) is an ensemble of programs that handle the creation and all access to databases 11.Linear syntax is a computer-programming term for an expression that can be parsed from left to right. Linear syntax implies the ability to write code without the use of line feed or carriage-return characters 12. Flowchart: is a type of diagram that represents an algorithm, workflow or process, showing the steps as boxes of various kinds, and their order by connecting them with arrows. 13.RDBMS: relational database management system is a database management system (DBMS) that is based on the relational model as invented by E. F. Codd, of IBM's San Jose Research Laboratory. In 2017, many of the databases in widespread use are based on the relational database model. 14.Row: It is a set of fixed and ordered scaled values. A scalar is defined as a single entity value or a series of characters
15.Support: to bear or hold up (a load, mass, structure, part, etc.); serve as foundatio n for. 16.Transaction log: is a history of actions executed by a database management system used to guarantee ACID properties over crashes or hardware failures. Physically, a log is a file listing changes to the database, stored in a stable storage format. 17.Operator: one that operates a machine or device 18.Logic level: a logic level is one of a finite number of states that a digital signal can inhabit. Logic levels are usually represented by the voltage difference between the signal and ground, although other standards exist. The range of voltage levels that represents each state depends on the logic family being used. 19.Relational security is the knowledge and understanding staff have of a patient and of the environment; and the translation of that information into appropriate responses and care. 20.Operational: is defined as a continual cyclic process which includes risk assessment
